Podcasts about ocean circulation

Dr. Gavin Schmidt, Director of NASA's Goddard Institute for Space Studies, joins us for a deep dive into climate science, climate modeling, and the future of sustainable civilization. Gavin shares insights on the Arctic's rapid warming, machine learning's role in climate predictions, and the impact of methane emissions. We also explore how climate science intersects with astrobiology and the search for extraterrestrial civilizations.

As Gabriel says in the interview, if the AMOC collapses then we can expect much harsher weather in Europe (especially in UK & Ireland) as less heat is transported via the Atlantic circulation. Less heat means less moisture leading to less rain and more drought. In these conditions, food production is impossible and, with concurrent food crashes around the globe, famine is likely. What an AMOC collapse means for us all should be understood by citizens and policymakers alike. Averting it, if possible, a primary collective goal. From Climate Genn host Nick Breeze: Welcome to this ClimateGenn Episode. That opening clip was recorded on the Cryosphere Pavilion at COP29 in Baku. It shows IPCC Deputy Chair, Diana Urge-Vorsatz asking Professor Stefan Rahmsdorf about the latest research on the potential halting of the Atlantic Meridional Overturning Circulation – known as AMOC –  the ocean currents that transport heat from the tropics to the north Atlantic.  In this following interview with researcher Gabriel Pontes, we expand on his recent AMOC research and what this means for places like the UK and Ireland, identifying key components of the AMOC puzzle. We also consider whether policymakers should be weighing this kind of climate risk more seriously. If you are interested in how the COPs have been manipulated and rendered unfit for purpose by successive governments then you can order my book ‘COPOUT' from any online retailer. COPOUT traces my own footsteps documenting the failures that have led us to where we are now in the era of severe consequences.

Humans depend on the life produced in the planet's oceans. But new scientific modelling shows the oceans' capacity to sustain those necessary marine resources faces a new threat – and very soon. A new Australian study has found the deep ocean circulation that forms around Antarctica could be headed for collapse over the next three decades, bringing with it significant implications for the oceans, marine ecosystems and the climate for centuries to come. R.Sathyanathan, a veteran broadcaster, explains the story. Produced by RaySel. - தென்துருவப் பிரதேசங்களில் பனிக்கட்டிகள் வேகமாக உருகுவதன் காரணமாக கடல் நீர் மட்டம் உயருவது ஒரு பிரதான பிரச்சனையாக எழுந்துள்ளது. கடல் நீர் மட்டம் உயர்ந்து கடலில் மிக ஆழத்திலுள்ள நீரின் சுழற்சியின் வேகம் பாதிக்கப்படுவதால் காலநிலை மாற்றங்கள் துரிதமடைவதாகவும் கடல் வாழ் உயிரினங்கள் பாதிக்கப்படுவதாகவும் இந்த ஆராய்ச்சிகள் தெரிவிக்கின்றன. இந்த விவகாரம் குறித்து விளக்குகிறார் பிரபல வானொலியாளர் இரா.சத்தியநாதன்.

As the Intergovernmental Panel on Climate Change predicts future warming, climate scientists play a crucial role in understanding what ecosystem functions and services are impacted by climate change. Without effective climate science communication, coordination and collaboration among federal agencies, NGOs, scientists, and legislators, environmental policymaking processes will be incredibly difficult. In this episode, ELI's Georgia Ray speaks with ELI Science Fellow John Doherty about his paleoclimatology research, current climate change policy discussions, and barriers associated with making climate science education accessible.  ★ Support this podcast ★

Fact Check My Feed: Why Are People Taking Discredited Horse Medicine For COVID-19? If you've been online at all in the past few weeks, you've probably seen discussion about the drug ivermectin. It was originally developed as an antiparasitic treatment for livestock, and in 2015, the Nobel Prize in Medicine went to scientists who found that it helped control parasitic diseases in humans as well. But recently, non-medical groups have been incorrectly promoting the drug as a treatment for COVID-19—even though the coronavirus is a virus, not a parasite. Virologist Angela Rasmussen of the University of Saskatchewan joins Ira to look at the data behind sometimes hyperbolic COVID-19 claims, from the latest on booster shots to the emergence of a new coronavirus variant in South Africa.     What Happens If Atlantic Ocean Currents Cease To Churn? Early last month, the Intergovernmental Panel on Climate Change released its latest report. It was a grim document, concluding that global warming had already set in motion irreversible levels of sea level rise, along with other changes that are threatening lives and health around the globe. The report focused in part on climate tipping points, or phenomena that, if they occur, could lead to a long term re-setting of our global climate and cascades of dangerous changes. Included among tipping points like the loss of the Amazon rainforest and melting of the permafrost, was the potential shutdown of the Atlantic meridional overturning circulation—the AMOC, for short. That circulation, a set of currents that includes the Gulf Stream, ferries cold water from the poles toward the equator, and distributes heat from the equator to northern latitudes. And it's powered by two things that are both changing as the climate warms: the temperature of ocean water, and the varying concentrations of salt in that water.  Climate models that use data from thousands of years ago can help us predict what might happen if the AMOC shuts down. Because the currents are a huge source of heat redistribution globally, a shutdown could have a complex array of consequences, from rainfall disruptions in the southern hemisphere, to even greater sea level rise on North America's east coast. And if it shuts down completely, it may not come back on again in any of our lifetimes. Unfortunately, researchers have been finding evidence that the circulation is, in fact weakening, including a study published in the journal Nature Climate Change in early August. Ira talks to Levke Caesar, a researcher at Maynooth University's ICARUS Climate Research Center. While not affiliated with the latest research, her work has helped map the ongoing pattern of weakening in the AMOC.       A Sourdough Saga, From Starter To Slice What makes sourdough taste sour? Was the first bread invented, or discovered? How did scientists eventually figure out that yeast and bacteria were the true master bakers? Will commercial bread ever be as good as that hand-baked loaf? Ira releases his inner breadmaking nerd in this conversation with Eric Pallant, author of the forthcoming book Sourdough Culture: A History of Breadmaking From Ancient to Modern Bakers.  

One of the world's major ocean currents is slowing down and this could have a devastating effect on our climate and livelihoods. The Gulf Stream in the Atlantic Ocean, which helps warm Europe, is at its weakest level in a thousand years and if this continues, it could lead to more extreme and intense winters.

This week in the Planet Earth Podcast - how the Romans recycled glass, dinosaur colour, and what Europe's gravity mission tells us about ocean currents. Did you know that the height of the world's oceans can vary by as much as 200 metres? These huge differences depend almost entirely on very slight changes in gravity across the world. Sue Nelson goes to the National Oceanography Centre in Southampton to find out more. We also hear that even the Romans recycled glass. But were they being green, or did they have other reasons?

Richard Hollingham goes to Norwich to meet the archaeologists with the answer. Finally, what colour do you think dinosaurs were? Until now artists have been free to paint them whatever colour they felt like. But not anymore - scientists now have a way of figuring out what colour they were. Richard goes to Bristol University to get the low-down from one of the scientists at the forefront of this research.

The oceans are a critical component of the climate system, storing roughly 1000 times as much heat, and 50 times as much carbon, as the atmosphere. In this talk, Professor David Marshall (21st Century Ocean Institute, University of Oxford) will discuss the challenges of predicting the evolution of a complex system that is grossly under-sampled and spans a bewildering range of scales in both space and time. These challenges will be illustrated through the important but over-sensationalised problem of how the Gulf Stream may change over the next century and impacts on European climate.
