Podcasts about West Antarctica

About seven hundred emperor penguins in West Antarctica, only six months old, huddled together at the edge of a towering icy cliff fifty feet above the frigid water. Finally, one penguin leaned forward and took “a leap of faith,” diving into the icy water below and swimming away. Soon scores of penguins took the plunge. Young penguins typically jump just a couple of feet into the water for their first swim. This group’s death-defying leap was the first to be caught on camera. Some people would say that the blind leap into the unknown by those penguins is similar to what happens when a person trusts in Jesus for salvation. Putting faith in Him is just the opposite. The author of Hebrews said, “Faith is confidence in what we hope for and assurance about what we do not see” (Hebrews 11:1). Enoch’s faith pleased God: “Without faith it is impossible to please God” (v. 6). The world hadn’t seen anything like the great flood and yet Noah, “in holy fear built an ark to save his family” (v. 7) because he trusted in God. By faith Abraham followed God “even though he did not know where he was going” (v. 8). When we first put our trust in Jesus it is by faith. As we continue following Him and our faith is tested, we can remember how God came through for these men. Even when we don’t know the whys and how’s we can trust God with the outcome.

The Antarctic Ice Sheet (AIS) has historically lost mass, significantly contributing to sea-level rise, with intensified losses in West Antarctica and parts of East Antarctica, particularly from 2011–2020.  However, between 2021 and 2023, driven by anomalous precipitation, the AIS experienced a record-breaking mass gain, even reversing trends in critical glacier basins like Totten, Moscow, Denman, and Vincennes Bay. Jimmy and Americans' Comedian Kurt Metzger discuss whether all this hullaballoo about climate change and melting ice caps may be so much hot air. Plus segments on Israeli police beating up Hasidic Jews in Jerusalem for protesting the Gaza genocide, Donald Trump signing a ban on gain of function research and former congressman and presidential candidate Dennis Kucinich discussing the condescendingly warmongering ways of Arkansas senator Tom Cotton.

China is planning another summer research station in West Antarctica. Officially, the focus should be on climate research. But experts fear that the expansion could fuel geopolitical tensions, particularly as the new facility will be located in a previously “unclaimed” region. - China plant eine weitere Sommerforschungsstation in der Westantarktis. Offiziell soll der Fokus auf Klimaforschung liegen. Doch Experten fürchten, dass die Expansion geopolitische Spannungen befeuern könnte, vor allem da der neue Standort in einer bisher „unbeanspruchten“ Region liegt.

This week we dive into the history and science behind Antarctica and question who made it out: Childs or MacReady? The Thing is a 100% PERFECT film. Grab your flamethrower and join in. About our guests:Peter Neff is a glaciologist and climate scientist working primarily to develop glacier ice core records of past climate, environmental conditions, and atmospheric chemistry. Peter's current research focuses on better understanding recent climate of changing coastal regions in West Antarctica, areas which play a large role in uncertainty for future projections of sea level rise. Peter is also working to capture the last 200-500 years of hydroclimate variability in southwestern British Columbia, Canada, through recovering and developing the southernmost annually-resolved ice core record in North America, from Mount Waddington in the Coast Mountains. Peter is also the Director of Field Research and Data for the Center for Oldest Ice Exploration (COLDEX), a National Science Foundation Science and Technology Center that seeks to find the oldest possible ice core records of past climate preserved in Antarctica. Peter shares widely about ice core climate science via Twitter, TikTok, and Instagram.Matthew Siegfried is a glaciologist who uses satellite remote sensing techniques in combination with field-based and airborne geophysical methods to understand physical processes of Earth's glaciers and ice sheets. He runs the Mines Glaciology Laboratory, where the team collects and synthesizes ground-, air-, and space-based datasets in an effort to span the spatial (centimeters to 100s of km) and temporal (minutes to centuries) on which these processes occur. He is particularly interested in processes at the ice-bed interface, which lies hidden beneath 10s to 1000s of meters of ice at the intersection between glaciology, hydrology, geology, microbiology, and oceanography. He strives to work with a diverse set of researchers to create a unique perspective on the role of subglacial processes within the larger global Earth system. As a polar scientist, Matt is also committed to maintaining an open discussion of the changing cryosphere, having collaborated with institutions ranging from local elementary schools to the U.S. State Department in an effort to facilitate our conversation about the local, regional, and global impacts of changes at the Earth's poles. Matt is currently an assistant professor in the Department of Geophysics at Colorado School of Mines and is affiliated faculty with the Hydrologic Science and Engineering Program and the Humanitarian Engineering Program.Daniella McCahey's primary research attempts to connect Antarctic geographies to greater world history. Her current book project examines the United Kingdom's 1955-1958 Commonwealth Trans-Antarctic Expedition, arguing that the way this project unfolded demonstrated a scientific community unable to cope with the twin pressures of decolonization and the Cold War. Dr. McCahey has broad interests and has authored/co-authored articles and scholarly book chapters on topics ranging from the media-savvy of Elizabeth Bowes-Lyon, to paleontology and popular culture in the 1990s, to pornography in Antarctic research stations. She is also conducting ongoing international collaborative research projects on the history of permafrost science and on the history of the British Empire's use of science in its Southern Ocean empire.

A team of scientists say seawater flowing underneath and into gaps in the Thwaites Glacier in Antarctica is contributing to the melting of the massive ice formation — a potentially ominous sign of the coming effects of human-driven climate change from the world's widest glacier. These areas of the glacier may be undergoing "vigorous melting" from warm ocean water caused by climate change, which could lead to even more rapid sea-level rise around the globe. The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise — is the world's widest glacier and roughly the size of Florida. It's also Antarctica's most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice. Thwaites, which already contributes 4% to global sea level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world's coastal communities.

Dr Dan Price is a glaciologist with research work focussing on Antarctic sea ice thickness with satellite and airborne sensors. He has been to Antarctica 8 times for both scientific research and program and logistical support. He developed crevasse avoidance techniques for heavy vehicle traverses across the world's largest ice shelf- the Ross Ice Shelf which is roughly the size of France. This involved finding a new 1,000km long route across the West Antarctica using novel satellite techniques. Dan took this theoretical investigation and was able to put it in to practise in Antarctica with his participation in the initial traverse. Dan has now driven across the Ross Ice Shelf 6 times. In 2015 he led a campaign called Pole to Paris to draw attention to the COP21 climate conference. He cycled a push bike from New Zealand to France over an 8 month period passing though more than 18 countries. During this expedition he gave presentations about the threat of climate change to people who will most likely be affected by sea level rise. He is currently the Chief Scientist for Christchurch based aerospace company Kea Aerospace, who are developing high altitude solar powered aircraft for earth observation. These initiatives will enhance our ability to respond to natural disasters by reducing the time it takes to assess impacts and damage from these events. Dan remains involved in sea ice research at Gateway Antarctica at the University of Canterbury and plans to launch a project to undertake the largest sea ice study ever conducted in Antarctica by flying a sea ice measuring instrument 5,000km from New Zealand's Scott Base to Australia's Casey Station. Dan has a bachelor of science from Cardiff University in Marine Sciences and a doctorate (PhD) in sea ice remote sensing from the University of Canterbury. He's an Edmund Hillary Fellow and is actively involved in not for profit organisations.

IS CLIMATE CHANGE REAL OR IS IT BULLSHIT PROPAGANDA? Your complete guide to false propaganda masquerading as serious commentary about climate change Commentary on 3 December, 2015 With the United Nations climate change summit now underway in Paris, those opposed to tackling greenhouse gas pollution from fossil fuels are engaged in a last-ditch desperate attempt to prevent a new international agreement. It is little surprise then that ‘The Wall Street Journal' has published a long and rambling polemic by two of the UK's most prominent campaigners against the regulation of the pollution from fossil fuels. The article by Matt Ridley and Benny Peiser of the Global Warming Policy Foundation, which lobbies against policies to reduce greenhouse gas emissions, recycles a series of ‘sceptic' talking points, to create a false impression of the science and economics of climate change. They start with the standard ploy of misrepresenting the scientific evidence for climate change. First they claim that global mean surface temperature has “gone up only very slowly”. They add that “the world is barely half a degree Celsius (0.9 degrees Fahrenheit) warmer than it was about 25 years ago”. In fact, the World Meteorological Organisation has warned that the last five years are the warmest such period since instrumental records began in the 19th century, and that the average global temperature for 2015 is likely to be about 1 centigrade degree higher than the average during the pre-industrial era, before the burning of fossil fuels started to dump large volumes of carbon dioxide into the atmosphere. Viscount Ridley and Dr Peiser downplay the significance of this rise in global mean surface temperature, which may seem small compared to local daily fluctuations. But it should be remembered that the global mean surface temperature during the last Ice Age was only about 5 centigrade degrees lower than today. During the last major interglacial period, which ended about 116,000 years ago, global mean surface temperature was no more than 2 centigrade degrees higher than today, but the polar land-based ice sheets on West Antarctica and Greenland were much smaller, and global mean sea level was between 5 and 10 metres higher than today. This shows the profound consequences of what may appear to be relatively small changes in global mean surface temperature. Viscount Ridley and Dr Peiser next seek to obscure the impacts of the rise in global mean surface temperature that has already occurred, falsely claiming that “on a global scale, as scientists keep confirming, there has been no increase in frequency or intensity of storms, floods or droughts”. This is blatantly misleading. The most authoritative assessment of the scientific evidence, published by the Intergovernmental Panel on Climate Change in 2013, concluded: “Changes in many extreme weather and climate events have been observed since about 1950”, including a likely rise in the frequency of heatwaves in large parts of Europe, Asia and Australia, and an increase in the number or intensity of heavy precipitation events in North America and Europe. Viscount Ridley and Dr Peiser try to hide the true picture on floods and droughts by ignoring the fact that the impact of climate change varies between regions, which means some parts of the world are becoming drier while other parts are becoming wetter. Hence the IPCC noted that “although the most evident flood trends appear to be in northern high latitudes, where observed warming trends have been largest, in some regions no evidence of a trend in extreme flooding has been found”. And on drought, the IPCC found that “it is likely that the frequency and intensity of drought has increased in the Mediterranean and West Africa and decreased in central North America and north-west Australia since 1950”. Similarly the data for storms across the world also presents a complex picture, but the IPCC noted that it is “virtually certain” there has been an “increase in the frequency and intensity of the strongest tropical cyclones since the 1970s” in the North Atlantic basin. Hence, the attempt by Viscount Ridley and Dr Peiser to focus only on global trends is really an obfuscation of the evidence of regional changes. They also turn a blind eye to the growing number of studies that have analysed how climate change has increased the probability of different types of extreme weather. Recent research by scientists around the world found that climate change influenced the probability of the frequency and severity of many extreme weather events in 2014.

As Earth's climate warms, more ice is melting near the poles. And that is a huge driver of sea level rise around the globe. But some coastal communities are threatened by this more than others.Places like the Gulf coast of Texas, for example, are feeling the impact of melting ice in West Antarctica, thousands of miles away.NPR Climate Correspondent Rebecca Hersher traveled to Galveston, Texas, to see how that ice melt is affecting sea levels there and what experts are doing to prepare. This reporting is part of NPR's Beyond the Poles: The far-reaching dangers of melting ice series.In participating regions, you'll also hear a local news segment to help you make sense of what's going on in your community.Email us at considerthis@npr.org.

Transcript: Hey. Good morning. This is Robert at English 360. And today we talk about Glacier. Glacier as the Americans like to call it. Basically, glaciers are big bodies of ice and they hold a lot of freshwater and scientists believe that it is catastrophic if they were to melt because the sea levels we don't see new rapidly. There is an article in the news which talks about Doomsday Glacier. It says there's a Doomsday Glacier, which could raise sea level by several feet, two three feet, basically about a half meter or more.And it's trying to survive by its fingernails. Now, obviously, glaciers are not living animals. It's figurative. This glacier is on the edge. It may melt completely. And if it does, we will be in big trouble. Let's see why. Antarctica's so-called Doomsday Glacier, nicknamed because of its high risk of collapse and threat to global sea level, has the potential to rapidly retreat in the coming years, amplifying concerns over the extreme sea level rise that would accompany its potential demise.Now, this is a difficult word to pronounce. The Thwaites glacier, capable of raising sea level by several feet, is eroding along its underwater base as the planet warms. In a study published Monday in the Journal Nature Geoscience. Scientists mapped the glacier's historical retreat, hoping to learn from its past what the glaciers will likely do in the future. They found that at some point in the past two centuries, the base of the glacier dislodged from the seabed and retreated at a rate of 1.3 miles or about two kilometres per year.That's twice the rate that scientists have observed in the past decade or so. So basically this huge glacier, which is rooted to the seabed now, is starting to detach. And one basic problem is that if it detaches from the seabed, it's going to melt more quickly. That swift disintegration possibly occurred as recently as the mid-20th century, according to a study.It suggests that Thwaites has the capability to undergo a rapid retreat in the near future once it recedes past a seabed ridge that is helping to keep it in. Thwaites is really holding on to today by its fingernails, and we should expect to see big changes over small timescales in the future, even from one year to the next.once the glacier retreats beyond a shallow ridge in its bed. The Thwaites glacier located in West Antarctica, it's one of the widest on earth and is larger than the state of Florida. But it's just a fraction of the West Antarctic ice sheet, which holds enough ice to raise sea level by up to 16 feet or about five meters, according to NASA.As the climate crisis has accelerated, this region has been closely monitored because of its rapid melting and its capacity for widespread coastal obstruction. The Thwaites glacier itself has concerned scientists for decades. As early as 1973, researchers questioned whether it was high risk of collapse. Nearly a decade later, they found that because that glacier is grounded to seabed rather than to dry land, well, ocean currents to melt the glacier from underneath, causing it to destabilize from below.It was because of that research that scientists began calling the region around the Thwaites the weak underbelly of the West Antarctic ice sheet. In the 21st century. Researchers began documenting the Thwaites rapid retreat in an alarming series of studies. In 2001, satellite data showed the grounding line was receding by around 0.6 miles or about one kilometer per year.In 2020 scientists found evidence that warm water was indeed flowing across the base of the glacier, melting it from underneath. And in 2021, a study showed that Thwaites ice shelf, which helps to stabilize the glacier and hold the ice back from flowing freely into the ocean could shatter within five years. From the satellite data we're seeing these big fractures spreading across the ice shelf surface, essentially weakening the fabric of the ice, kind of a bit like a windscreen crack slowly spreading across the ice shelf, and eventually it's going to fracture into lots of different pieces.Monday's findings, which suggest that Thwaites is capable of receding at a much faster pace than recently thought, were documented on a 20 hour mission in extreme conditions that mapped an underwater area the size of Houston, according to a new release. So there we have it. Basically this massive Armageddon of glacier or glacier like Americans like to call it is slowly melting.If it melts, catastrophe will take place literally. When glacier stored, fresh water is released to the sea and atmosphere. It brings about massive changes. It threatens agriculture, power generation and drinking water supplies. A study on New Zealand's glaciers has shown that glacier retreat closely tracks atmospheric carbon dioxide levels and as glaciers continue to melt, their loss will impact supplies of fresh water for drinking and a host of other human activities.This is how they can affect people around the world. Populous Asian countries such as China and India get much of the late summer river flow volume they rely on from glacier meltwater. In dry periods, the population of La Paz, Bolivia, relies heavily upon glacial meltwater from an ice cap. Farmers in Switzerland, Rhone Valley, have relied upon glacial meltwater to irrigate their crops for centuries by channeling it to their farms.Glacial meltwater drives, hydropower plants all around the world. Bottling companies package glacial mineral water, glacial melt water and even ice cubes made of glacial ice are in demand for specialty drinks. I mean, in essence, we rely on glaciers as a form of national water storage infrastructure. We don't have natural water. We don't have glaciers. They take on water in winter and release it evenly during warm months.But if precipitation remains the same, does it really make a difference? Yes, because glacial ice, sequesters water in a way that prevents it from evaporating readily without glaciers even if precipitation remains constant in high mountainous areas, that water will remain in liquid form, subject to peak evaporation and runoff. Whichever way you look at it, glaciers are fundamental to our survival and it is alarming that we are losing them by kilometers every year because of global warming.Big fossil fuel companies don't want you to think about this prospect of glacial melting. It goes against their profit, they would like you to use fossil fuels until they completely run out whether we are still able to live on this planet or not. It's up to us essentially to make those tough decisions. It's a very difficult prospect, but we must do our best.With this, we end it here. I hope you like this podcast.

Very long and very widebut only a few kilometres thick, atmospheric rivers carry water from the tropics towards the poles – and they shift huge amounts of heat as well. A few decades ago, atmospheric rivers hit West Antarctica and collapsed two massive ice shelves.

In segment one of this Utterly Moderateepisode we are joined by Dr. Richard Alley (professor of geosciences at Penn State University) to discuss climate change's impact on the Doomsday Glacier (the nickname given to the Thwaites Glacier in West Antarctica) and the potentially catastrophic consequences that this could have for sea level rise and coastal cities across the globe. Some research suggests that in as little as five years the glacier could suffer a massive collapse. In segment two we take a look around the news at a few stories from this past week, including: Possible Russian invasion of Ukraine (Wall Street Journal) Pittsburgh bridge collapse (Pittsburgh Post-Gazette) Supply chain woes (the Bulwark) Moderna vaccine gets full FDA approval (Washington Post) Foreign journalists in China face intimidation (Axios) Illiberal Right and Left are asymmetrical (the Bulwark) Trump floats Jan. 6 pardons (CBS News) Trump admits wanting to overturn election (Snopes.com) Trump wanted to seize voting machines (New York Times) Episode Music: “Please Listen Carefully” by Jahzzar (creative commons) “Draw the Sky” by Paul Keane (licensed through TakeTones) “Reading by Lamplight” by Maarten Schellekens (creative commons) “Happy Trails (To You)” by the Riders in the Sky (used with artist's permission)   See omnystudio.com/listener for privacy information.

In this episode we are going to talk about what happens when the polar ice caps melt, with a focus on effects seen in the earth's crust and permafrost loss. Ongoing ice loss in West Antarctica has increased over the past few decades. Measurements since the 1950s indicate that the amount of sea ice in the Arctic has been declining. Permafrost in the Arctic alone is estimated to hold nearly twice as much carbon as exists in the atmosphere now, as well as a sizable amount of methane, and losing it turns what is one of the greatest carbon sinks on earth to a major emissions source. Since the retreat of a glacier can reduce stress loads on Earth's crust underneath, impacting the movement of subsurface magma, this can lead to volcanic activity and other surface implications.

It's no secret that the glaciers of Antarctica and Greenland are melting at a catastrophic rate. This is raising public concern, but truthful information about the true reasons is not conveyed to the general public. From this video, you will learn:

The planet's core is now having the greatest impact on the climate, contrary to the theory of the anthropogenic factor. Destabilization of the core leads to more volcanic eruptions and destructive earthquakes, and the weakening of the magnetic field. A number of unprecedented changes are taking place in our planet's core:

For Dr. Jennifer Kay (she/her/hers), global warming and ice loss brings up many headspaces. “I'm curious, scared, hopeful, frustrated, and inspired all at once.” As a climate scientist at the University of Colorado, understanding the physics of snow, clouds and ice is her job. Growing up in upstate New York, she spent most of her days skiing, sledding, and loving snow. It's not surprising that she loves all things cold. Now, she's a doctor, professor, and highly cited researcher with a focus on polar regions. In our warming world, polar regions are losing snow and ice. For example, the loss of land-based ice in West Antarctica and Greenland is currently causing irreversible sea level rise. Because land-based ice sheets can melt and collapse so much faster than they can be rebuilt from snow accumulation, this current land ice melt is irreversible on human timescales. Irreversible keeps Dr. Kay up at night. What will happen to the billions of dollars, lives, and ecosystems that depend on coastal environments? What will happen to Island Nations and Coastal Cities? Does everyone understand what is at stake here? Dr. Kay stresses: “We have a shared climate future. Investing in infrastructure and committing to reduce greenhouse gases are encouraging steps, but more action is needed. Irreversible ice loss is just one of many reasons we need to reduce greenhouse gas emissions now.” On this episode, we talk about the climate crisis, how adventurers and scientists can work together and about gender bias in climate science.

Grab your parkas, put on those winter boots, don't forget those big ol mittens and hang out with us tonight as we head to the place where the coldest temperature on earth has ever been recorded, a mild -89.2°C (-128.6°F). Maybe we should bring swim trunks instead, eh? Well, aside from the coldest temps known anywhere, there is also possibly Nazis, maybe a hole to the center of the earth, a blood waterfall, and giant sea spiders with legs ranging up to 70cm, and for those of you who aren't sure if that's big or not cus we're a bunch of archaic buttholes that don't do metric… It's big.. Like close to 28 inches big… oh and how could we forget… the Penguins!! Lots of penguins! Well, if you haven't figured it out yet, we're heading to Antarctica! We're going to be discussing the continent and find out a little about it and then we'll talk about some creepy natural things going on and of course creepy conspiracies. It should be a fun one so let's get going!!!   So let's learn a little about Antarctica first off. Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Most of Antarctica is a polar desert, with annual precipitation of 200 mm (8 in) along the coast and far less inland; yet 80% of the world's freshwater reserves are stored there, enough to raise global sea levels by about 60 metres (200 ft) if all of it were to melt. The temperature in Antarctica has dropped to −89.2 °C (−128.6 °F) (or even −94.7 °C or −138.5 °F, as measured from space), although the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra. Wanna know some fun facts… Well, tough shit negative Nancy, we're gonna tell ya anyways.    Antarctica holds most of the world's fresh water An incredible 60-90% of the world's freshwater is locked in Antarctica's vast ice sheet. The Antarctic ice sheet is the largest on Earth, covering an incredible 14 million km² (5.4 million square miles) of Antarctic mountain ranges, valleys and plateaus. This leaves only 1% of Antarctica permanently ice-free. Some areas are ice-free in the summer, including many of the areas we visit on the Antarctic Peninsula.   At its deepest, Antarctica's ice is 4.5km (2.7 miles) thick – that's half the height of Mt Everest! Again, If it all melted, global sea levels would rise about 60 m (200 ft).   As mentioned, Antarctica is a desert With all of that fresh water held in the ice sheet, how could Antarctica be a desert?   When most of us think of deserts we think of sand dunes, cactuses and sizzling temperatures, but technically a desert doesn't have to be hot or sandy, it's more about how much precipitation the area receives as rain, snow, mist or fog. A desert is any region that receives very little annual precipitation.   The average annual rainfall at the South Pole over the past 30 years was just over 10 mm (0.4 in). Although there is more precipitation towards the coast, the average across the continent is low enough to classify Antarctica as a polar desert.   So, while Antarctica may be covered in ice, it has taken an incredible 45 million years to grow to its current thickness, because so little rain falls there.   As well as being one of the driest continents on Earth, Antarctica is also the coldest, windiest and highest.   Antarctica used to be as warm as Melbourne Australia! Given that the coldest ever land temperature was recorded in Antarctica of -89.2°C (-128.6°F), it can be hard to imagine Antarctica as a warm, temperate paradise. But Antarctica hasn't always been an icy land locked in the grip of a massive ice sheet. In fact, Antarctica was once almost as warm as Melbourne is today.   Researchers have estimated that 40-50 million years ago, temperatures across Antarctica reached up to 17°C (62.6°F). Scientists have also found fossils showing that Antarctica was once covered with verdant green forests and inhabited by dinosaurs!   The Antarctic Peninsula is one of the most rapidly warming areas on Earth The Antarctic Peninsula is warming more quickly than many other areas on Earth. In fact, it is one of the most rapidly warming areas on the planet. Over the past 50 years, average temperatures across the Antarctic Peninsula have increased by 3°C (37.4°F), five times the average increase on Earth.   This has led to some changes, for example where and when penguins form colonies and sea ice forms. It also means that the lush mosses of the Antarctic Peninsula have a slightly longer growing season.   There is no Antarctic time zone The question of time in Antarctica is a tricky one. At the South Pole the lines of longitude, which give us different time zones around the globe, all meet at a single point. Most of Antarctica experiences 6 months of constant daylight in summer and 6 months of darkness in winter. Time starts to feel a little different without the normal markers for day and night.   Scientists working in Antarctica generally stay in the time zone of the country they departed from, but this can cause some issues. For example, on the Antarctic Peninsula you can find stations from Chile, China, Russia, the UK and many other countries. You can imagine that if all of these neighbouring stations keep to their home time zones it could get a little confusing trying to share data and resources without accidentally waking one another up in the middle of the night!   For travellers with Aurora Expeditions, they generally stay on Ushuaia time – unless they're travelling to the Falkland Islands and South Georgia. Then they adjust to their local times, changing as they travel.   Every way is north! If you stand at the South Pole, you are at the southernmost point on Earth. It doesn't matter which way you look, every direction is north. So why do we talk about the Antarctic Peninsula as being in West Antarctica, and the section directly south of Australia as East Antarctica?   It's based on the prime meridian, an imaginary line which passes through Greenwich in the UK at 0 degrees of longitude. If you stand at the South Pole and face towards Greenwich, everything to your left is west Antarctica and everything to your right is east Antarctica. Got that?   Antarctica has active volcanoes Antarctica is home to several volcanoes and two of them are active. Mount Erebus, the second-highest volcano in Antarctica, is the southernmost active volcano on Earth. Located on Ross Island, this icebound volcano has some unique features such as ice fumaroles and twisted ice statues that form around gases that seep from vents near the volcanic crater.   The first ascent of Mt Erebus was made in 1908, when a team led by Australian scientist Edgeworth David, and including Douglas Mawson, completed an arduous and very chilly five day climb to the steaming crater.   The second active volcano is on Deception Island, a volcanic caldera in the South Shetland Islands. Once home to a thriving whaling station and later a scientific station, it was abandoned after the most recent eruption in 1969, and today it is a fascinating place that we visit on some of our Antarctic Peninsula voyages.   Antarctica has its own Treaty When humans caught their first glimpse of Antarctica in 1820, it was the only continent without an indigenous population. Several nations quickly made claims to the continent, which led to significant tension. While some countries argued that Antarctica was rightfully theirs, others heartily disagreed.   As tension mounted, everyone agreed on the need for a peaceful resolution. In December 1959, 12 countries signed the Antarctic Treaty, an unprecedented international agreement to govern the continent together as a reserve for peace and science. Since then, 41 other countries have signed the Treaty and participate in annual meetings, where decisions are made about how human activity in Antarctica is managed. All decisions made within the Antarctic Treaty System are made by consensus, with collaboration and agreement as the central pillars. Today, the Antarctic Treaty System has expanded to include strict guidelines for commercial fishing, sealing, and a complete ban on mining and mineral exploration.    We got those fun facts  from Aurora expeditions. Com   So let's look at some of the weird natural phenomena that goes on in Antarctica.    You guys like weird sounds? Well we got weird sounds for you. Scientists and researchers at the Ross ice shelf have recorded a slow seismic hum being generated by wind whipping across the Antarctic ice shelves. The scientists also discovered that the frequency of the vibrations changed in response to changing weather conditions on the shelf — when the temperature rose or fell, for instance, and when storms resculpted the shelf's snow dunes. The firn was "alive with vibration," Douglas MacAyeal, a glaciologist at the University of Chicago, said in a written commentary that accompanied the paper. "This vibration was found to be driven by the wind blowing across the firn layer and interacting with the intrinsic roughness of the surface called sastrugi." MacAyeal also offered a more poetic description of the sound, comparing it to "the buzz produced by thousands of cicada bugs when they overrun the tree canopy and grasses in late summer."   Julien Chaput, a geophysicist and mathematician at Colorado State University in Fort Collins and the leader of the research, told NBC News MACH in an email that the sound was "a little like yodeling, except with 10 people all singing in dissonance. It's a little eerie." But the singing ice is more than a sonic curiosity. Chaput and his colleagues argue in their paper that it might be possible to tap into seismic data to help monitor the health of ice shelves, which have been thinning in response to global warming — and causing sea levels to rise around the world. so that's all pretty crazy. Antarctica is singing to us. (Play sound)   Ever hear of a solar pillar? Well you're about to. The air in Antarctica is frequently very dry. The low temperatures mean that little or no water vapour is held in the air, instead it freezes and falls out, or builds up on surfaces as frost. Sometimes however, depending on the particular atmospheric conditions, the frozen water vapour remains in the air as suspended ice crystals. In these conditions the crystals can reflect sunlight in a variety of ways forming atmospheric phenomena of different types.   One of these phenomena is the "Solar Pillar" in the picture. The sun is reflected very strongly off tiny suspended flat ice crystals in the air which are oriented at or almost horizontally, so that the reflection is almost as bright as the sun itself. Like a rainbow, this sight depends on the viewing angle, where the light is coming from and where the observer is standing. The pillar appears to move when the observer moves, but always remains directly below the sun because the ice crystals are found throughout the air but only act as mirrors for the sun at the correct viewing angle.   Most of you have heard of the northern lights, but did you know there are southern lights? The Southern Lights, commonly known as the Aurora Australis, is one of the world's greatest wonders. The Southern lights are much more elusive than their Northern Hemisphere counterpart-Aurora Borealis. There is significantly less land mass in the Southern Hemisphere and fewer ideal viewing spots to see the Aurora. However, the Southern Lights are just as, if not more, impressive. Boasting a breathtaking colour palette that goes beyond the green and blues commonly seen at the Northern Lights, to include pinks, purples, oranges and golds.   Here's a little nerdy science for ya: The Aurora Australis phenomenon occurs when charged particles from solar winds bombard the Earth's atmosphere and interact with gases in our planet.   These highly energised particles are emitted from the sun and smash into the Earth's magnetic field at more than 6 million kilometres per hour.   For the most part, Earth is protected from solar winds by the magnetosphere, which sounds like Magneto from the X-Men franchise's bachelor pad. The magnetosphere is a region of space that surrounds the Earth's magnetic field and has a primary purpose of preventing cosmic rays, such as solar winds from entering Earth's atmosphere. However, occasionally, at particular times of the year, a few charged particles from solar winds make their way through the magnetosphere into our atmosphere. The charged particles move along the Earth's magnetic field lines towards the south and north pole. When they reach the each pole, they collide with atoms in the atmosphere, particularly nitrogen and oxygen, and become increasingly charged. Once the electrons settle back down to their normal level of excitement they glow, creating the magnificent light display, we know as an Aurora.   One more fun natural thing for you guys and probably the creepiest. BLOOD FALLS! THIS FIVE-STORY, BLOOD-RED WATERFALL POURS very slowly out of the Taylor Glacier in Antarctica's McMurdo Dry Valleys. When geologists first discovered the frozen waterfall in 1911, they thought the red color came from algae, but it's true nature turned out to be much more spectacular.   Roughly two million years ago, the Taylor Glacier sealed beneath it a small body of water which contained an ancient community of microbes. Trapped below a thick layer of ice, they have remained there ever since, isolated inside a natural time capsule. Evolving independently of the rest of the living world, these microbes exist in a place with no light or free oxygen and little heat, and are essentially the definition of “primordial ooze.” The trapped lake has very high salinity and is rich in iron, which gives the waterfall its red color. A fissure in the glacier allows the subglacial lake to flow out, forming the falls without contaminating the ecosystem within. If you've never seen the falls it's pretty awesome and metal. We'll post pics for sure.   Ok so enough of the sciency and nerdy stuff let's get into the crazy shit.    The first one is a fun one. In 2020 a clip from Google Earth was loaded onto youtube showing what appears to be an ice ship! So what exactly is it? Well friends, it depends on what you want to believe. The video sparked a conversation of epic conspiracy proportions! Some think that the "ship" is something connected to a secret Nazi base, which we'll get to later. Others claim ties to the secret elite and illuminati.    “I was told a couple of years ago that there are ships built underground somewhere on upper east coast (like the ones in the movie 2012) to save the rich and powerful when canary islands get hit with massive earthquake that will take out east coast,” one commenter wrote.    Other theory's range from military and government cover ups to some claiming it to be Noah's ark. The mundane exfoliation is that it's our minds playing a trick on us… but that's fucking lame and we're going with the fact that it's something creepy and crazy!!   Another fun thing found by Google Earth is a giant mountain sized alien face. Yes you heard right. And if you don't think this is leading to crazy talk… You are seriously mistaken.    Conspiracy theorists Blake and Brett Cousins – of YouTube channel thirdphaseofmoon – shared their thoughts on the Google Earth image.   "It appears to be a massive, ancient structure of some kind of face that is being revealed for the first time on Google Earth,” Blake said in his video.   "I would have to concur that whatever we're looking at resembles some sort of megastructure."   Brett added: "Could this be something that was left behind by the ancient civilisations of Antarctica?   "Ice melting could be revealing structures that would baffle the world."    There it is folks, a giant alien face structure hiding a civilization under Antarctica. Can't argue with the facts. I mean I guess you could say that it's just a case of pareidolia but that's not really that fun so… You know… Alien civilization it is.    Speaking of aliens, A video posted to an “alien" sub-section on Reddit shows how zooming in on a certain area of South Georgia and the South Sandwich Islands reveals a mysterious vast section of disturbed snow. It shows what looks like something that crashed into the snow and skidded some 3000ft. Of course that brought out the nut jobs, and moody, claiming that it is a ufo crash site.    Reddit user Hey-man-Shabozi captioned the post: "What's over 200ft long, casts a shadow of 50ft, and appears to have crashed on an antarctic  island, moving so fast that it slid over 3,000ft?”   The island, located near Antarctica, has a strange snow formation in the area near Mount Carse.   It looks very similar to an avalanche but the video posted on Reddit goes into detail about how it could be more than what it seems. The main point of contention for the Reddit user is that there appears to be a long thin object that has created a lengthy straight track away from the disrupted area as if it crashed at speed. The Reddit user estimated that the tracks were more than 3,000 feet long.   He also claims to have worked out that the object responsible was 200 feet long.   Let's be honest… If you can't trust a reddit user… Who can you trust these days? Of course most people will say “oh it was just a big rock falling during an avalanche”, but everyone else who actually knows… They know it's a ufo. And they all know that the claims of a rock falling during an avalanche is just another global cover up to hide the fact that there are aliens.  Another one comes thanks to a visual grab from Google Earth, which seems to suggest that there might actually be a tall building standing on the ice in Antarctica. These findings have been uploaded to YouTube Channel MrMBB33 (who coincidentally was also responsible for finding the ice ship we discussed earlier) and the conspiracy theorist who runs this channel suggests that this structure is as much as 2,000 feet in height and the width spans six football fields. Viewers are clearly interested in what they are seeing. “Strange that all countries want to take over land but no country claims Antarctica. I think there is something they know that we don't," comments a user Lorrie Battistoni. Another user suggested that something on the lines of the Project Iceworm was active in Antarctica—the Project Iceworm was a then top-secret project of the United States Army which attempted to build a network of tunnel based and mobile nuclear missile launch sites under the ice sheet in Greenland. Equally, there are sceptics who suggest this is nothing more than a block of ice, albeit with a slightly different shape.     Since we brought up tunnels, there's supposedly an air vent on top of a “metallic shield” in a no-fly zone on the icy continent. Estimates are that the area is over 150 feet wide — based on measurements using Google Earth tools. Its two distinctive features: a pitch-black “opening” and a metal-like “shield.”   "That looks like some sort of vent, a thermal vent that goes underground. You can tell that the snow is darker than any other snow in the surrounding area,” one person said “That would imply to me that there is heat transfer going on” and suggests the top section is some metal or metal alloy man-made structure “over an opening that goes underground.   Someone else points out there is no volcanic activity nearby: “It is just there all by itself.”   So what is it? Just a cave? A man made structure hiding a secret underground base? Should we just go back to aliens for this one? What do you guys think? Ok how about Hitler and the Nazis? Well since people believe there are Nazis and maybe even Hitler himself still hiding out in Antarctica. This theory originates from a story about a Nazi expedition to Antarctica.  The story says that while exploring and mapping the area, they uncovered a multitude of underground caves and rivers.  One of the caves was particularly large and was turned into a large city that would be home to both Nazi's and other powerful groups, like the illuminati.  Along the way, the Germans either came across alien technology or made contact with the aliens.  The Germans learned how to use the technology and were able to build a number of weapons.  This belief is extraordinary because there is no evidence that the Nazis ever did, or were even capable of building such a base.  Geologist and Oceanographer, Colin Summerhayes, partnered with journalist and historian, Peter Beeching, to examine evidence about Antarctica and the Nazis. In  support of this claim is the fact that the Nazis did at one point carry out an expedition to Antarctica in 1938.  Many conspiracy theorists claim that this was a large-scale expedition, with militarized and scientific ships. Another bit of evidence for this theory is about the Nazi's agreeing to The Antarctic treaty.  The treaty makes Antarctica a research zone and states that Antarctica cannot be targeted in any way by bombs or missiles.  Conspiracy theorists jump on this and say why would Nazi Germany sign this agreement?  The claim is that they signed this agreement to deter other nations from visiting Antarctica and stumbling upon their base and the research being done there.  There has been no evidence found to corroborate that point.  Additionally, some claim that Hitler himself is actually in Antarctica.  The evidence for this idea is based on the claim that a German ship arrived at an Argentinian base located in Antarctica after the war ended.  Another popular conspiracy theory is that Hitler escaped to Argentina at the end of the war, and so therefore he was picked up by a German ship, and sent to Antarctica to live at the secret bunker.  However there is no evidence that Hitler ever made it to Argentina or that the supposed German boat ever went to Argentina's Antarctic base… At least that's what they want you to believe! Since there have been other strange military activity there such as supposed German boats coming or the U.S. project “Operation Highjump”, since people really think that this is a feasible thing. Of course These strange events, and the lack of information around them, often lead people to conclude that it must be because there is something going on there that the government doesn't want us to know about.  Many of these beliefs actually come from Flat Earth.  Flat Earthers often propose that it is illegal to go to Antarctica and has a constant military presence, that's why none of them can go investigate if the ice wall is out there.  There is a subgroup of flat earth who believes that part of the reason you “can't go” to Antarctica is because of the Nazi base there. So think about that one...flat earthers believing there are Nazis bases in Antarctica… Good Lord. In 1978, Miguel Serrano, a Chilean diplomat and Nazi sympathizer, published El Cordón Dorado: Hitlerismo Esotérico [The Golden Thread: Esoteric Hitlerism] (in Spanish), in which he claimed that Adolf Hitler was an Avatar of Vishnu and was, at that time, communing with Hyperborean gods in an underground Antarctic base in New Swabia. Serrano predicted that Hitler would lead a fleet of UFOs from the base to establish the Fourth Reich. In popular culture, this alleged UFO fleet is referred to as the Nazi flying saucers from Antarctica. Oh boy. We really gotta figure out if the Nazis are on the moon or in Antarctica!   How about pyramids… You like pyramids? We got pyramids… maybe. THE oldest pyramids on Earth are hidden away under the deep cold snow of Antarctica, conspiracy theorists have shockingly claimed . Ancient alien theorists who are certain secret pyramids are concealed all around the globe, think some may be hidden on Antarctica. Conspiracy theorists, in particular, point to a pyramid-like structure near the Shackleton mountain range on the icy continent. The “pyramid” in question, when viewed on satellite imagery, does appear to have four steep sides much like the Great Pyramid of Giza. Conspiracy theory author David Childress told Ancient Aliens there is a distinct possibility the Shackleton pyramid is the oldest of its kind on Earth.   He said: “If this gigantic pyramid in Antarctica is an artificial structure, it would probably be the oldest pyramid on the planet and in fact, it might be the master pyramid that all the other pyramids on planet Earth were designed to look like.” Another conspiracy theorist agreed, saying: "All the way around the world we find evidence of pyramid structures.   "We should start looking at the possibility there was habitation on Antarctica.   "Was it a lost civilization? Could it be ancient astronauts?   "And just maybe, the earliest monuments of our own civilization came from Antarctica.”    But the theory was challenged by Dr Michael Salla, author of Exopolitics Political Implications of the Extraterrestrial Presence. The alien expert argued the Antarctic pyramid is just one node in a global network of power-generating pyramids strategically placed around Earth.   A popular pyramid conspiracy claims the triangular structures act as power generators of sorts, built for the purpose of transiting vast amounts of energy wirelessly.   Dr Salla said: “There has been extensive research done on pyramids throughout the world, in terms of their structure and what they really are.   “One of the theories is that pyramids are power generators and so if you have these pyramids strategically placed around the world generating a charge, it's possible to create a general standing wave around the world that is a wireless transmission of energy.”   Also There is a claim that the British set up a base called Maudheim-1 (there are no records) in Dronning Maud Land during the war to observe the apparent Nazi base, this was supposedly attacked by the Nazis in July 1945 followed by SAS led (failed) retaliatory attacks from October to December that year.   How about a couple quick hits:    Some think that the remains of a  Motte and Bailey castle were uncovered. Motte-and-bailey castle is a European fortification with a wooden or stone keep situated on a raised area of ground called a motte, accompanied by a walled courtyard, or bailey, surrounded by a protective ditch and palisade. Relatively easy to build with unskilled labour, but still militarily formidable, these castles were built across northern Europe from the 10th century onwards, spreading from Normandy and Anjou in France, into the Holy Roman Empire in the 11th century. The Normans introduced the design into England and Wales. Motte-and-bailey castles were adopted in Scotland, Ireland, the Low Countries and Denmark in the 12th and 13th centuries.    The structure is about 120m across which makes it of the appropriate size range and has two sort-of circles, though the whole thing appears to be more or less completely flat rather than having any significant raised earthworks which in part define a Motte and Bailey castle, the mounds of such castles in towns, cities and in the countryside in Europe are particularly enduring across the centuries. There's a scientific explanation for it but that doesn't stop people from believing what they want.    Then of course you have the flat earthers . There is a weird conspiracy theory that Antarctica and the South Pole do not exist. This belief is most common among flat-earthers who claim that our planet is flat. Flat-earthers believe that the North Pole is at the center of the world while the South Pole surrounds the Earth. According to flat-earthers, Antarctica is actually a thick wall about 30 to 60 meters (100 to 200 ft.) high that surrounds our planet. The wall stops everything from falling over the edge of the Earth. Flat-earthers say we cannot confirm the existence of the wall because world governments and the United Nations have strict no-fly and no-sail zones around Antarctica. Conspiracy theorists believe that the British Captain Cook is one of the few humans to have ever seen the wall apart from government agents. Supposedly, Captain Cook reported seeing the huge wall during the three voyages he made to Antarctica. The wall covered the entire coastline, and he could not land anywhere because it was just too tall to climb.   Speaking if stupid, we touched on this not long ago so we'll just mention it in passing… But apparently there's a hole at the south pole that is the entrance to the hollow earth...I mean… Come On people… Is this where we are as a society??   Going along with this theory of a hole at the pole, there are people that think the world is hiding that fact with a fake south pole. So when people go to the spot that is thought to be the south pole is actually an arbitrary random spot chosen by the powers of the world to throw everyone off the trail of hollow earth.    Some people also believe that there is actually a tropical region that is  hidden in Antarctica. Yes, a tropical region. Some say it is in the no fly zone that is also attributed to the spot where the hole to hollow earth is… we think these guys should fight it out. To the death. Like, no survivors. On the other hand there is recent evidence that there used to be rain forests on the continent so maybe the believers aren't as crazy as we think. Just kidding. They're nuttier than squirrel turds.   Some other crackpots also really believe Antarctica is the Land of The Ancient Race of Super-Beings With Big Angular Heads. Some of them tried to leave many years ago and made it to Easter Island where their enormous weight made them sink into the ground and a simple common bacterial infection turned them to stone. The bacterium cannot live in Antarctica so they continue their highly sophisticated secret society under the ice, dude we can't make this stuff up. Maybe it was Medusa… see, we can make shit up, too!   And finally… Is Antarctica really the lost city of atlantis? The theory that Antarctica is Atlantis is a relatively new one, dating back to the mid 20th Century.   According to Charles Hapgood's 1958 book 'Earth's Shifting Crust',  the continent of Antarctica was in fact originally much further north than its current position. Due to the shifting of the Earth's crust, the continent was displaced, and the climate of the continent, which had been mild, plummeted to below freezing.   This shift in location and temperature has led some to argue that an ancient Civilisation existed on the continent, which was subsequently destroyed by this monumental geographical realignment.   In 2016, faint credence was given to this claim with the revelation that remains of a human settlement had been found under the Antarctic ice.   One report claimed, 'the pictures, taken using remote sensing photography for NASA's Operation IceBridge mission to Antarctica, show what online sleuths believe could be a city.'

In this episode, I converse with Meghana Ranganathan, a fourth-year Ph.D student in Climate Science at the Department of Earth, Atmospheric, and Planetary Sciences at MIT. Meghana completed her undergraduate education at Swarthmore College and received a B.A. in mathematics, with a specialization in applied mathematics. Her past research has been on eclectic areas of interest, including focuses on El Nino-Southern Oscillation forecasting, statistical paleontology, and building queuing theory models for emergency rooms to identify bottlenecks in the intake process. Meghana is also passionate about diversity, equity, justice, and inclusion in STEM and has been actively involved in education and activism around issues of racism and colonialism in the geosciences. Meghana's current research focuses on the dynamics and energetics of ice streams in West Antarctica, illuminating processes on the micro-scale and connecting micro-scale processes with macro-scale dynamics. We indulge in a fascinating conversation on her terrific journey in science; naturally discovering maths in college and flaws with mathematical pedagogy in schools; applying a mathematical lens to solving the pressing challenge of the day - climate change; grad school and confronting the ubiquitous imposter syndrome; the importance of lucid science communication; breathtaking research on glaciology; engaging communities on the ground; forays into writing and the storytelling aspect of science; and many more things!!

What is the Doomsday Glacier? Thanks for asking!The Thwaites Glacier in West Antarctica is melting rapidly and risks breaking up completely. For nearly a quarter of a century, climate scientists have been observing it closely and have nicknamed it the Doomsday Glacier due to its instability and potential impact on the future of the planet. Thwaites Glacier is more than 1km deep and has a surface area of 74,000 m2, larger than all of England. It’s more than 1,000 miles away from the closest research base, making it remote even for Antarctica.The speed at which the glacier is melting has increased due to currents of warm water flowing underneath it, wearing away at its base. A study published last month by Gothenburg University researchers showed that the quantity of warm water, measured for the first time using a robotic unmanned submarine, was far higher than previously thought. How long ago did the glacier start melting? What will happen if the glacier disappears? I bet it isn’t the only glacier in the world that’s causing concern...

Melting glaciers in West Antarctica might collapse due to the effects of human-caused global climate change, but there are also risks in Antarctica's eastern part.

In this episode of podcast I have talked about Antarctica. I have talked about its physical geography and its history and at last little bit about its facts.Additional Info: Modern plate boundaries may be far different from ancient ones presumably marked by old fold belts. Ancient Antarctic mobile belts, such as are followed by today's Transantarctic Mountains, terminate at continental margins abruptly, as if sliced off, and seemingly reappear in other lands across young ocean basins. Much research has been concentrated on attempting to match intercontinentally the detailed structure of opposed coasts, such as between Antarctica and Australia, in an effort to learn whether they had been actually connected before the latest cycle of crustal spreading from intervening mid-oceanic ridges. Similarities between ancient mobile belts now suggest to some geologists that Antarctica may even have been connected to southwestern North America more than 600 million years ago, in late Precambrian time. Surface temperature trends show significant warming across the Antarctic Peninsula and to a lesser extent West Antarctica since the early 1950s, with little change across the rest of the continent. The largest warming trends occur on the western and northern parts of the Antarctic Peninsula. There the Faraday/Vernadsky Station has experienced the largest statistically significant (

In this episode of the podcast, I have talked about the Polar Region. It is a little bit long podcast but you will definitely like it for sure.Additional Info:Why are changes in sea ice so important to the polar regions?Sea ice is a dominant feature of polar oceans. Shifts in the distribution and extent of sea ice during the growing season impacts the duration, magnitude, and species composition of primary and secondary production in the polar regions. With less sea ice many marine ecosystems will experience more light, which can accelerate the growth of phytoplankton, and shift the balance between the primary production by ice algae and water-borne phytoplankton, with implications for Arctic food webs. In contrast, sea ice is also an important habitat for juvenile Antarctic krill, providing food and protection from predators. Krill is a basic food source for many species in polar marine ecosystems.Changes in sea ice will have other impacts, beyond these “bottom-up” consequences for marine food webs. Mammals and birds utilize sea ice as haul-outs during foraging trips (seals, walrus, and polar bears in the Arctic and seals and penguins in the Antarctic). Some seals (e.g., bearded seals in the Arctic and crabeater and leopard seals in Antarctica) give birth and nurse pups in pack ice. Shifts in the spatial distribution and extent of sea ice will alter the spatial overlap of predators and their prey. According to model projections, within 50 to 70 years, loss of hunting habitats may lead to the elimination of polar bears from seasonally ice-covered areas, where two-thirds of their world population currently live. The vulnerability of marine species to changes in sea ice will depend on the exposure to change, which will vary by location, as well as the sensitivity of the species to changing environmental conditions and the adaptive capacity of each species. More open waters and longer ice-free periods in the northern seas enhance the effect of wave action and coastal erosion, with implications for coastal communities and infrastructure. Although the overall sea ice extent in the Southern Ocean has not changed markedly in recent decades, there have been increases in oceanic temperatures and large regional decreases in winter sea ice extent and duration in the western Antarctic Peninsula region of West Antarctica and the islands of the Scotia Arc.Twitter: https://twitter.com/realyashnegiSuggestions are always welcome: yashnegi4920@outlook.comSupport the show (https://paypal.me/yashnegi27?locale.x=en_GB)

If the Thwaites Glacier in West Antarctica slides into the sea, this has consequences for the entire world. Many coastal cities could flood and entire countries could become uninhabitable. Barbara Barkhausen spoke to several researchers about the developments on the so-called “Doomsday Glacier” with concern. “We already know that the glacier is degrading enormously,” says Keith Nicholls from Great Britain. “The main section of the glacier could already have crossed the threshold of stability.” The latter is also confirmed by the American Ted Scambos. “Ice is not as firm as rocks, for example,” he says. “I don't want to sound depressed now, but it is likely that the glacier is already in the early stages of collapse.” Once the collapse has started, it cannot be stopped. - Rutscht der Thwaites-Gletscher in der Westantarktis ins Meer hat dies Folgen für die gesamte Welt. Etliche Küstenstädte könnten überfluten, ganze Länder unbewohnbar werden. Barbara Barkhausen sprach mit mehreren Forscher die Entwicklungen am sogenannten „Doomsday Glacier“ mit Sorge beobachten. „Wir wissen bereits, dass der Gletscher enorm abbaut”, sagt der Brite Keith Nicholls. „Das Hauptstück des Gletschers könnte die Schwelle der Stabilität bereits überschritten haben.“ Letzteres bestätigt auch der US-Amerikaner Ted Scambos. „Eis ist nicht so fest wie Gestein beispielsweise“, sagt er. „Ich will jetzt nicht depressiv klingen, aber es ist wahrscheinlich, dass der Gletscher bereits in der Anfangsphase des Kollapses ist.“ Ist der Kollaps einmal initiiert, lässt er sich nicht mehr stoppen.

The effects of our changing climate extend from main street to the ends of the Earth. Warmer air and oceans are melting the ice cap at the north pole, for example. And a recent study says the same thing is happening in the Antarctic.In recent decades, the West Antarctic Ice Sheet has been melting at an increasing pace. It contains about six million cubic miles of ice. But glaciers on its edge are getting smaller. Scientists have suspected that global climate change is playing a role. But natural changes in the Pacific Ocean also change the rate at which the glaciers melt.A recent study tried to separate the natural variations from those caused by humans. Researchers looked at Antarctic ice records compiled by satellites over the last 40 years. They also looked at records of changes in the Pacific Ocean going back a century. Those changes have a direct influence on conditions in the Antarctic. The researchers then used climate models to simulate what’s going on.They found that warmer air is changing the winds across West Antarctica. Instead of blowing mainly from the east, the easterly and westerly winds balance out. That’s allowing warmer waters to flow past the West Antarctic Ice Sheet. The warmer water melts some of the ice.On average, the glaciers are losing enough ice to increase global sea level by a couple of inches over the next century. As the air gets even warmer, though, that rate should increase – adding more water to the oceans at the bottom of the world.

New research found evidence that swampy rainforests once existed in Antarctica. A team of European scientists discovered plant fossils in the region, which proves that there used to be temperate rainforests less than 600 miles from the South Pole. Published in the journal Nature, the research confirms findings of previous studies about Antarctica's past, including evidence of an animal that could only survive in warmer climates. In 2017, experts extracted soil samples from the seafloor near the Pine Island Glacier in West Antarctica. Using the soil content drilled from that location, the researchers estimated that the temperature on the continent used to reach up to 25 degrees Celsius during the summer. Sixty-five varieties of plants dated around 83 to 92 million years ago were discovered in the sample, which revealed that the area possibly had swampy rainforests. Such forests are comparable with the ones present in the north-western region of New Zealand's South Island. Lead author Johann Klages said that a temperate environment near the South Pole would only exist if there were higher greenhouse gas concentrations and plenty of vegetation in the area. This finding implies that ice sheets were non-existent in the location millions of years ago. According to organic geochemistry expert Dr. James Bendle, investigating the ecosystem of Antarctica is significant in understanding the implications of climate change. He added that if the levels of carbon dioxide in the atmosphere continue to rise to extreme levels, humans can expect a planet with little to no ice in the future.

Esther Jansen spreekt in deze podcast over de mogelijkheden om het mens-zijn, of onze menselijkheid, opnieuw vorm te geven in het licht van het Antropoceen. Op welke manieren zit het huidige mensbeeld ons in de weg om deze broodnodige vormen te zien, te verbeelden, en het dagelijks leven naar in te richten? Het werk van Sylvia Wynter geeft aanknopingspunten om de vraag ‘wat betekent het om mens te zijn?’ op een andere manier te beantwoorden, en laat zo de tekortkomingen van het westers idee van ‘de Mensheid’ zien. Wat kunnen we hier van leren in het licht van de huidige ecologische ontwrichting? Deze lezing was onderdeel van de avond: Eco- catastrofe: de mens moet anders (18-02-2020) Dat de aarde verandert is overal om ons heen zichtbaar. We leven in vreemde tijden die vragen om radicaal handelen. We worden geconfronteerd met gevoelens van onbegrip, angst, onmacht en wanhoop, maar belangrijker nog worden we geconfronteerd met conceptuele kaders die niet langer houdbaar zijn. Hoe ver moeten we gaan in ons denken om mee te kunnen met de tijd? Klimaatverandering zet de kaders die wij sinds de Verlichting vanzelfsprekend achten op het spel: Wie is eigenlijk de ‘mens’ die in het Anthropoceen tot geologische kracht wordt verheven? Wat is onze rol? Staat de mens wel los van (en boven) de natuur? En is ons menselijke lot niet eigenlijk toch innig verbonden met dat van de kleinste wezens, met het plankton, de insecten? Wat moeten we denken van de massale uitsterving van soorten om ons heen? In 2019 lagen wereldwijd slechts twee landen op koers om hun doelen uit het Parijsakkoord te halen (te weten: Marokko en Gambia). Dat betekent volgens het (vaak conservatief geachte) IPCC dat we afstevenen op een opwarming van 3-4 of 4-5 graden boven pre-industrieel niveau in 2100 (rapport 2018). In een wereld van gemiddeld 4 graden extra bevindt de bewoonbare wereld zich in West-Antarctica, Canada, Noord-Europa en Rusland. Ter contrast: Zuid- en Midden- Amerika, de Verenigde Staten, Afrika, Zuid-Europa, Zuid- en Oost-Azie en Australië zijn onbewoonbaar door woestijnvorming, extreme droogte of overstromingen. Zoals Bruno Latour het zegt hebben we een oorlog reeds verloren, al vochten we hem wellicht niet bewust. Het gevolg? We draaien met zijn allen door. De een ontkent, de ander panikeert, een derde hoopt tegen beter weten in. De vreemde wereld waarop we leven vraagt om verandering, échte verandering. En in plaats van ons te laten verleiden tot cognitieve dissonantie, in plaats van de route van de vervreemding te nemen die ons onvermijdelijk op afstand plaatst van het geheel, blijven we deze avond dicht op de materie, en dicht op onszelf. Kan ons zelfbeeld standhouden? Tijdens deze avond van Felix & Sofie nemen we de ecologische catastrofe als uitgangspunt om te kijken naar de conceptuele, filosofische, maar ook substantiële revoluties die komen.

The planet is warming, from North Pole to South Pole. Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. In Montana's Glacier National Park, the number of glaciers has declined to fewer than 30 from more than 150 in 1910. --- Send in a voice message: https://anchor.fm/vijay-sonawane/message

Melting of Antarctica's massive Thwaites Glacier could add 60 centimetres to global sea level rise in the next 50 to 100 years, and unlock far more in the years beyond. A voyage by an icebreaker to the remote glacier's face laid the groundwork for a 5-year international research effort to try to answer urgent questions about Thwaites' future. Our reporter Carolyn Beeler takes us onboard the expedition, with deep dives into the science and the stakes for our future. (The Nathaniel B. Palmer anchored off the Rothera research station near the Antarctic Peninsula. Nearing its destination offshore of the Thwaites Glacier in West Antarctica, the ship had to divert back north to the station for a medical emergency. Carolyn Beeler/The World)

On a rocky island just off the coast of West Antarctica, ecologist Lars Boehme is standing face-to-face with a 1,500-pound elephant seal, eyeing the animal's bulbous nose and jowls to see if he's finished shedding his fur. When the seal opens his mouth wide to bellow, Boehme waves his hand in front of his face like he's just smelled something foul.

The Grand Duke of the Grand Duchy of Flandrensis takes two hours and thirty minutes out of his hectic governing and parenting schedule to pay a digital diplomatic visit to the third-world basement micronation of Expatria. His Highness and your host discuss at length the long laundry list of absurdities that go into founding and maintaining a microstate, the internecine disputes that arise between microstates (the majority of them ruled over by prepubescents), and the ecological objectives that the Grand Duke has in mind for his uninhabited Grand Duchy in the West Antarctic, a land that he has yet to visit himself, and one that he strongly discourages others from visiting, too.

On this weeks episode of Expanded Perspectives the guys start the show off talking about how bee populations around the world have been in decline for years due to a number of reasons that make it extremely difficult to fix the problem. Urban development, insecticides, fungicides, illness, climate change, and many other factors have been determined to be responsible for the decline in bee populations. This week, the nonprofit Bee Informed Partnership and the Apiary Inspectors of America published their annual survey of 4,963 beekeepers in the United States and it seems that we still have a problem. But it was a slightly better year for our vital pollinating friends. Then, millions of Americans say they engage in extreme binge drinking — or downing at least eight to 10 drinks containing alcohol on a single occasion — and the behavior appears to be on the rise in the U.S., according to a new report. The findings are concerning because this high level of drinking is linked with health and safety risks, including an increased risk of injury or even death, according to the researchers, from the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The study "reveals that a large number of people in the United States drink at very high levels and underscores the dangers associated with such 'extreme' binge drinking," George F. Koob, director of the NIAAA, said in a statement. The researchers analyzed information from more than 36,000 Americans ages 18 and older who completed a survey about their alcohol consumption in 2012 to 2013. The researchers asked the participants to report the maximum number of alcoholic drinks they consumed on a single day in the past year. Binge drinking was defined as consuming four or more drinks on a single occasion (for women), or five or more drinks on a single occasion (for men), while extreme binge drinking was defined as consuming double those amounts, or more. Then, for years, scientists have debated whether heavy inland snowfall on the vast East Antarctic Ice Sheet — Earth’s largest — balances out the rapid melting in West Antarctica. Given enough snowfall, the continent might not yet be contributing to sea level rise. Most research shows the melt rate is so high that the continent is indeed losing ice. But in 2015, a group of NASA scientists published a controversial study that found Antarctica was instead gaining ice. The NASA team combined space- and land-based measurements and found so much snow dropping in East Antarctica that even with drastic melting elsewhere, the continent was adding some 80 billion tons of ice annually. It contradicted prominent previous findings — including reports from the U.N.’s Intergovernmental Panel on Climate Change. The result drew global headlines and excited climate change skeptics. That’s despite warnings from the study’s lead author, NASA Goddard’s chief cryospheric scientist Jay Zwally, who predicted that melting would outpace increased snowfall in a decade or two. Then, An Arizona witness traveling by train through Apache County reported watching and photographing six hovering, “two-story” objects beaming light to the ground level. After the break Cam brings up the incredible tale of "The Black Flash". Shadowy figures have long haunted the pages of history. From ghosts to goblins to things less mentionable, the human psyche has a habit of inventing monsters to inhabit the dark reaches of the unknown. Several such figures have been chronicled: the Halifax Slasher, the London Monster, and Spring-Heeled Jack, to name a few. Today, we’ll be adding another cloaked and hooded terror to the rogue’s gallery, this one known by a name straight out of a comic book: the Black Flash.

Frostbyte by Muto Atsuhiro, for the World Climate Research Programme (WCRP) workshop 16-18 October 2013, Tromsø, Norway Workshop webpage climate-cryosphere.org/meetings/wcrp-cryo-gc-2013http://pdl.vimeocdn.com/64424/724/197865148.mp4?token=1382722341_2ca717a3efa39b8b5d1d75df3b48154d

If you want to truly grasp the scale of the Earth's polar ice sheets, you need some help from Isaac Newton. Newton taught us the universal law of gravitation, which states that all objects are attracted to one another in proportion to their masses (and the distance between them). The ice sheets covering Antarctica and Greenland are incredibly massive—Antarctica's ice is more than two miles thick in places and 5.4 million square miles in extent. These ice sheets are so large, in fact, that gravitational attraction pulls the surrounding ocean towards them. The sea level therefore rises upward at an angle as you approach an ice sheet, and slopes downward and away as you leave its presence.This is not good news for humanity. As the ice sheets melt due to global warming, not only do they raise the sea level directly; they also exert a smaller gravitational pull on the surrounding ocean. So water sloshes back towards the continents, where we all live. "If Antarctica shrinks and puts that water in the ocean, the ocean raises around the world, but then Antarctica is pulling the ocean towards it less strongly," explained the celebrated Penn State glaciologist Richard Alley on this week’s episode. "And as that extra water around Antarctica spreads around the world, we will get a little more sea level rise in the US than the global average."Alley, a self-described “registered Republican” and host of the PBS program Earth: The Operators’ Manual, spoke on the occasion of truly dire news, of the sort that ice sheet experts like him have been dreading for some time. Last week, we learned from two separate research teams that the ice sheet of West Antarctica, which comprises just one relatively small part of Antarctic ice overall but contains enough frozen water to raise global sea levels by some 10 or 11 feet, has been irrevocably destabilized. Scientists have long feared that of all the planet's great ice sheets, West Antarctica would be the first to go, because much of it is marine-based—the front edge of the ice sheet is bathing in increasingly warm water, which is melting it from beneath. On the show this week we talked to Alley about the science of ice sheets and what this most recent news means for our future.This episode also features a discussion of a controversial project to replicate some of the most famous studies in social science, and of new research on whether firstborn children are more politically conservative than their later-born siblings.iTunes: itunes.apple.com/us/podcast/inquiring-minds/id711675943RSS: feeds.feedburner.com/inquiring-mindsStitcher: stitcher.com/podcast/inquiring-minds

Nathan, Mike, and Mahler talk about West Antarctica, Syria, Boko Haram, South Sudan, Ukraine, water cannons, war crimes, energy efficiency, Oklahoma earthquakes, death row, feeding the homeless, and Oprah Winfrey.

Feature #1: (start time: 06:03) On January 12, 2010, just over three years ago, a magnitude 7 earthquake shook Haiti, taking more than 200,000 lives and displacing an estimated 2 million. Still today, the International Organization for Migration estimates hundreds of thousands of people are without permanent homes, and in many ways Haiti seems no closer to rebuilding than it did three years ago.  Co-host Beth Bartel speaks to Haiti's first seismologists -- Roby Douilly and Steeve Symithe, both graduate students at Purdue University -- about the future of Haiti and a career in seismology there Feature #2: (start time: 15:42) You’ve probably heard by now that 2012 was the warmest ever in the U.S.  We’re not the only ones overheating. At the bottom of the world, over the last 50 years, West Antarctica has warmed more than scientists had thought. The implications are huge; an enormous ice sheet there  may be at risk of long-term collapse, which could cause sea levels to rise alarmingly.  Co-host Susan Moran speaks with Andrew Monaghan, a climate scientist at the National Center for Atmospheric Research, or NCAR, here in Boulder. Dr. Monaghan co-authored the study, which was recently published in the journal Nature Geoscience.

The Antarctic Peninsula forms part of a magmatic arc at least since Jurassic times. Magmatic dykes are essential elements of such arcs and intrude along zones of instability. In contrast to other hypabyssal intrusions and the effusive products of arc activity, dykes do not only reflect the geochemical characteristics of their magma source but also the tectonic parameters at the time of their emplacement. The South Shetland Islands form an archipelago located at the northern tip of the Antarctic Peninsula and belong to this arc. Areas of up to 100,000 m2 have been mapped at several locations of these islands, mainly on King George and Livingston Island. A structural analysis of the dykes and the host rocks was carried out, and about 250 dykes were sampled for further studies. As deduced from field relationships, on Livingston Island six different intrusive events could be distinguished, on King George Island up to seven. This subdivision into different intrusive events is also well reflected by the geochemical data. Analysis of the structural data of the dykes and their host rocks shows, that the tectonic stress field was not only very similar throughout the archipelago, but that moreover only minor changes of this stress field occurred during the time of dyke emplacement. This holds for all investigated areas in the South Shetland Islands. The geochemical data (ICP-MS) reveal, that most dykes of the South Shetland Islands belong to a calc-alkaline, arc-related suite, ranging from basalts to highly differentiated rhyolites. However, especially during early stages of intrusive activity in the respective areas, also tholeiites occur. Isotopic data (Sr, Nd, Pb) prove a strong crustal component during initial stages of magmatic activity, especially on Hurd Peninsula (Livingston Island). This crustal component decreased with time, accompanied by an increase of sedimentary input into the subduction zone. The high amount of crustal contamination during the initial stages was probably due to a still unstretched continental crust. Besides the continental crust underlying the South Shetland Islands, partial melts from the subducted sediments, fluids derived from the subducting plate and a depleted, heterogeneous mantle wedge contributed to arc magma genesis. According to Ar-Ar datings on plagioclase separates and K-Ar (WR) age determinations, dyke intrusion was restricted to the Paleocene and Eocene. The dykes started to intrude around the Cretaceous/Paleogene boundary at Livingston Island. Only around the Thanetian/Ypresian boundary, dyke intrusion commenced also further NE at Nelson and King George Island, culminating during the Lutetian at 47-45 Ma in all investigated areas. Dyke intrusion then ceased in the latter areas but still continued at Livingston Island until the Priabonian. Combining the information given by the tectonic and geochemical datasets, the time interval covered by the dykes obviously marks a period of geodynamic stability. This includes a stable geometry of the subduction zone and the corresponding parameters (subduction direction and velocity) during that time, as well as stable magma sources. The contribution of the respective sources (sediments, slab, mantle, crust) varied, but the sources themselves remained the same. Very primitive, olivine tholeiitic dykes sampled on Penguin Island as a by-product of this work yielded an unexpectedly high Ar-Ar age (Tortonian), thus questioning the onset of rifting in Bransfield Strait during the Pliocene, as believed so far.
