A recent study suggests the next ice age will likely begin in about 11,000 years unless emissions change the effects of natural climate cycles. 最近的一项研究表明，除非排放改变自然气候周期的影响，否则下一个冰河时代可能会在约11，000年内开始。 An ice age is a period of reduced temperatures causing ice to cover large areas of the northern and southern parts of the world. 冰河时代是温度降低的时期，导致冰覆盖了世界北部和南部地区的大面积。 A group of scientists studied changes in the shape of the Earth's orbit around the sun, the tilt of the Earth's axis and the movement of the axis itself, called a wobble. These three motions are believed to happen in cycles. The Serbian scientist Milutin Milankovitch developed a theory about 100 years ago that these cycles affected Earth's long-term climate. 一群科学家研究了地球围绕太阳的形状的变化，地球轴的倾斜以及轴本身的运动，称为摇摆。 据信这三个动作是在周期中发生的。 塞尔维亚科学家米兰科维奇（Milutin Milankovitch）大约在100年前开发了一种理论，即这些周期影响了地球的长期气候。 The team noted that small changes in Earth's orbit around the Sun caused predictable cycles of warming and cooling over a period of about 100,000 years. 该小组指出，在大约100，000年的时间里，地球围绕太阳围绕太阳的轨道的小变化导致了可预测的变暖和冷却周期。 These findings permitted the team to determine how the three factors of tilt, wobble, and the shape of Earth's orbit might have affected the Earth's climate over the last 900,000 years. 这些发现使团队能够确定倾斜，摇摆和地球轨道形状的三个因素如何影响过去900，000年的地球气候。 The group published its findings in Science on February 27. 该小组于2月27日在科学上发表了研究结果。 The scientists examined a million-year record of climate by looking at ice sheets across the northern half of the world and deep ocean temperatures.科学家通过查看世界北半部的冰盖和深海温度，检查了一百万年的气候记录。 They then compared this data with small but regular changes in Earth's orbit over time. 然后，随着时间的流逝，他们将这些数据与地球轨道的规律变化进行了比较。 The lead writer of the study is Stephen Barker, a professor at Cardiff University in Britain. He told the French News Agency (AFP) that for many years it has been difficult for scientists to show exactly how small changes in Earth's orbit have led to huge changes between warm and cold periods.该研究的首席作者是英国加的夫大学教授斯蒂芬·巴克（Stephen Barker）。 他告诉法国新闻社（AFP），多年来，科学家很难确切地证明地球轨道的小变化如何导致温暖和寒冷时期之间的巨大变化。 Earth is believed to go through cycles of ice ages and warm periods. The last ice age is thought to have ended around 11,700 years ago. Scientists, such as Milankovitch, have long seen a connection between Earth's orbit and climate. 据信地球经历了冰河时代和温暖时期的周期。 人们认为最后一个冰河时代大约在11,700年前结束了。 诸如米兰科维奇（Milankovitch）之类的科学家长期以来一直看到地球轨道和气候之间的联系。However, researchers have struggled to precisely date when each of the climate changes happened. It has also been difficult for them to know exactly which orbit positions affect the start and stop of cold or warm periods. 但是，研究人员在每种气候变化发生时都努力准确地日期。 他们也很难确切知道哪些轨道位置会影响寒冷或温暖时期的起点和停止。 Barker said his team of researchers studied slow changes in temperature over long periods of time instead of only looking at shorter periods of change between cold and warm climates. 巴克说，他的研究人员团队研究了长时间温度的缓慢变化，而不仅仅是看寒冷和温暖气候之间的变化时期较短。 Barker told AFP, "We would expect a glaciation to occur within the next 11,000 years, and it would end in 66,000 years' time." 巴克告诉法新社：“我们预计在未来11，000年内会发生冰川，这将在66,000年的时间内结束。” Lorraine Lisiecki is a professor at the University of California, Santa Barbara, and a co-writer of the study. She said the study shows that changes in climate over tens of thousands of years are not random.Lorraine Lisiecki是加利福尼亚大学圣塔芭芭拉分校的教授，也是该研究的共同作家。 她说，这项研究表明，数万年以上的气候变化不是随机的。 The team aims to expand its findings to investigate the long-term effects of human activity on climate. They also want to find out how it might affect Earth's natural climate cycles. 该小组旨在扩大其发现，以调查人类活动对气候的长期影响。 他们还想找出它可能会影响地球自然气候周期。

El término fue acuñado tras los estudios realizados por el astrónomo y geofísico serbio Milutin Milanković que en la década de 1920, teorizó que las variaciones resultantes provocaban cambios cíclicos en la radiación solar que llega a la superficie terrestre y que ello influía considerablemente en los patrones de los cambios climáticos sobre la Tierra.

Is Earth's crustal formation influenced by its position in the galaxy? And how would we know? It's obvious there are many celestial cycles, from the earthly ones that Milankovitch described to the orbit of the solar system through the galaxy, but how can we tie those to geological planetary cycles, like the 800 m.y. resonance of the core, the 500-300 m.y. supercontinent cycle, and the ~ 30 m.y. impact cycle? Professor Chris Kirkland and team from Australia's Curtin University have developed a zircon-based approach that they say can tease apart the cyclic secrets of crust formation. We talk radiometric dating, limits and benefits of the technique, asymptotic time horizons, and the difficulties of doing geology on a galactic scale.

14And God said, "Let there be lights in the expanse of the sky to distinguish between the day and the night and let them be signs to mark the seasons and days and years. 15And let them serve as lights in the expanse of the sky to shine upon the Earth." And it was so. 16God made two great lights: the greater light to rule the day and the lesser light to rule the night. And He made the stars as well.… Genesis 1: 14-16Each time I think of the cycle of the Earth, the above verses of scriptures come to mind; I pause and ponder, looking at it closely, and all I see is a cycle. I ask myself, does this cycle, this movement, literarily affect everything that the earth warehouses?In asking this question and researching the topic, I came upon this article titled 'Milankovitch (Orbital) Cycles and Their Role in Earth's Climate by By Alan Buis, 'Our lives revolve around cycles: series of events repeated regularly in the same order. Hundreds of different types of cycles exist in our world and the universe. Some are natural, such as the change of the seasons, annual animal migrations, or the circadian rhythms that govern our sleep patterns. Others are human-produced, like growing and harvesting crops, musical rhythms, or economic cycles.Cycles also play critical roles in Earth's short-term weather and long-term climate. A century ago, Serbian scientist Milutin Milankovitch hypothesized the long-term, collective effects of changes in Earth's position relative to the Sun are a strong driver of Earth's long-term climate and are responsible for triggering the beginning and end of glaciation periods (Ice Ages).Specifically, he examined how variations in three types of Earth orbital movements affect how much solar radiation (known as insolation) reaches the top of Earth's atmosphere as well as where the insolation reaches. These cyclical orbital movements, which became known as the Milankovitch cycles, cause variations of up to 25 percent in the amount of incoming insolation at Earth's mid-latitudes (the areas of our planet located between about 30 and 60 degrees north and south of the equator).' https://climate.nasa.gov/news/2948/mi... Milankovitch cycles%20include%3A,is%20pointed%2C%20known%20as%20precession.Looking at this research above, I see some answers to the question I have entertained for a while now, which has influenced my thoughts in this video. One's ignorance of things somewhat does not release the person from the consequences of not knowing, but it will put the person in an advantageous position if the individual is armed with a certain level of information and vis-a-vis knowledge that the person can manipulate in surmounting the challenges the person is likely to faceSupport the show

Patrick Albert Moore is a Canadian industry consultant, former activist, and past president of Greenpeace. Since leaving Greenpeace in 1986, Moore has criticized the environmental movement for what he sees as scare tactics and disinformation, saying that the environmental movement "abandoned science and logic in favor of emotion and sensationalism.” According to Greenpeace, Moore is "a paid spokesman for the nuclear industry, the logging industry, and genetic engineering industry” who "exploits long-gone ties with Greenpeace to sell himself as a speaker and pro-corporate spokesperson" Time stamps: 0:00:00 Opening thoughts 0:09:30 Podcast begins 0:10:45 The story of polar bears and how they tie into the global warming conversation 0:21:35 The first principle of science: skepticism  0:33:30 Climate and doomsday 0:42:30 Milankovitch cycles and climate change 0:54:30 Carbon dioxide isn't the issue 0:58:55 How growing plants in different levels of C02 affects their size 1:11:30 We are a tropical species 1:15:45 It's clear: temperature rises before the increase in carbon dioxide 1:28:15 The three ways heat moves from one place to another 1:32:30 C02 in the ocean   Sponsors: Heart & Soil: www.heartandsoil.co  White Oak Pastures: www.Whiteoakpastures.com, use code: CarnivoreMD for 10% off your first order Belcampo: www.belcampo.com use code: CarnivoreMD for 20% off your order Blazing Bull: $150 off of a 1500 degree grill at BlazingBullGrills.com with code “CARNIVOREMD” at checkout BLUblox: https://blublox.cc/ CARNIVOREMD for 15% off

Los movimientos de la Tierra puede que nos resulten un campo sencillo y muy intuitivo. A fin de cuentas, sabemos lo que es la rotación y la traslación... ¿no? Pero, ¿hay más movimientos? Y no solo eso... ¿Qué pasa con los ciclos de Milankovitch? Puede que hayamos oído hablar de ellos en algún momento, pero no tengamos muy claro qué impacto tienen en nuestro planeta...

This week on The Conduct Science Podcast, join Mitch and Tom as they explore the frozen expanses of ice ages. What classifies an ice age, how long do they last, how do they start in the first place? Did you know we are technically still in the same ice age in which woolly mammoths roamed the Earth?! Mitch explains Milankovitch cycles and other possible causes for ice ages while time takes us through the major ice ages in Earth's history. With a lot of interesting tangents along the way join us for this cool episode ;) Music: WhiteBatAudio.com

The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change the climate. Many other theories of climate change were advanced, involving forces from volcanism to solar variation. Thomas Edison, pioneer of electrical technologies, voiced concern for climate change and support for renewable energy in the 1930s.[1] In the 1960s, the warming effect of carbon dioxide gas became increasingly convincing. Some scientists also pointed out that human activities that generated atmospheric aerosols (e.g., "pollution") could have cooling effects as well. During the 1970s, scientific opinion increasingly favored the warming viewpoint. By the 1990s, as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory of the ice ages, a consensus position formed: greenhouse gases were deeply involved in most climate changes and human-caused emissions were bringing discernible global warming. Since the 1990s, scientific research on climate change has included multiple disciplines and has expanded. Research has expanded our understanding of causal relations, links with historic data and ability to model climate change numerically. Research during this period has been summarized in the Assessment Reports by the Intergovernmental Panel on Climate Change. Climate change, broadly interpreted, is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (such as more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as oceanic circulation), biotic processes (e.g., plants), variations in solar radiation received by Earth, plate tectonics and volcanic eruptions, and human-induced alterations of the natural world. The latter effect is currently causing global warming, and "climate change" is often used to describe human-specific impacts.

Recently, Global warming, Climate change and the decrease of ice caps have been more of an issue than ever. Most come to think its us who are the main causes but did you know it's really not just us we should be looking at. Believe it or not its space, space is a huge impact in the climate change role. Topics discussed in this podcast will be: -Climate Change - Milankovitch Cycle - Albedo - Moon

Welcome to Finance and Fury, the Say What Wednesday edition. Today we are going to cover off on Climate Change. This may be a bit weird. But, the majority of proposed solutions are political/economic. Firstly, the taxation on CO2 emissions. What is this going to do to the economy overall, with additional costs of business? Furthermore, capping of production of emissions. In this episode, we will discuss climate change in terms of the narrative that it is presented as. This is around rising temperatures and the world being doomed in a few years’ time. I won’t be talking about environmental destruction. Is global warming man made? How will the solutions help? The common theme of Fear: Different predictions over the last few decades A similar theme is fear Most people fear catastrophic events Predictions by experts on climate change keeps turning out to be incorrect From predictions, there was supposed to be a lot of misery in the world due to climate change caused events Policy changes due to global hysteria The climate change direction changed We look at an overview of predictions and temperature claims. We should be fearful of these events, right?   The issue with acting out of Fear: Opt for any solution we think will work Even if it is against our own self-interest How does this affect the brain? Social learning and context can be tools to help fears or make fears worse There is a potential to influence the way we experience fear Social isolation is another thing people are afraid of Climate change has religious elements to it This comes down to ideological subversion   The message is in our face every day: 97 movies since 2010 depicting the end of the world The irony of Hollywood around actions towards fighting climate change The hypocrisy of politicians surrounding climate change Paid to pretend to be someone else for a living Our climate does change, it’s the only consistent thing about it   The climate definitely changes, there is no clear consensus on why or how: 97% of climate scientists agree that humans are the leading cause of climate change Do they really? Christopher Monckton criticised John Cook’s findings These are unscientific findings UQ is now proving a free climate change course These claims can be broken down in the resources below Why don’t other scientists speak out about it? How well can weathermen predict the temperatures? Saying that it is human-induced through CO2 emissions is why I have an issue with this The mathematical modelling and their numeric assumptions What is the relationship between CO2 and temperatures? When do the records of temperature begin? What are the mathematical models and how do scientists come to their conclusions? Joseph Postma wrote A Climate of Sophistry, which covers the modelling and math involved The same modelling shows the increases in CO2 help boost plant life Milankovitch cycles describe Earth’s movements and the climate changes The debunking always goes in both directions Financially, who has the most to gain? Politicians, climate scientists, and the media. Summary: I am not denying that the climate does not change There is no measurable increase in temperature anomaly in 18 years Focusing on clean energy is a good idea, but following advice on voting for policy change doesn’t help long term How does the Paris Climate agreement help? Let's come up with some long term plans to help produce cleaner energy Thanks for listening today. If you want to get in contact you can at the contact page here.

Fine Music Radio — We all know the name Albert Einstein, not to be confused with the musicologist Alfred Einstein, and we know the famous e=mc 2 thing, even if we’re a bit hazy about what it means. But I certainly didn’t find the name Milankovitch rolling off my tongue – yet he should be commemorated as a very great scientist. Milutin Milankovitch was born in Serbia the same year as Einstein, and died just a year or two after the celebrated physicist. He was a mathematician, astronomer, geologist, climatologist and engineer – truly one of the great polymaths of the century. But his name is familiar to climatologists in the term Milankovitch Cycles. And it’s worth remembering that term. The news headlines seem obsessed with ‘global warming’ ‘climate change’ - one-and-a-half degree temperature increase – ‘fossil fuels versus sustainable renewables’. We’ve covered the territory here on Being Green haven’t we just? And it’s very important, not to be diminished. Public understanding has gone a long way to helping policymakers, industrialists, engineers, designers, make informed choices to avoid the worst pitfalls of unwise development. Milutin Milankovitch

Don't believe the hype! The's a big difference between an ice sheet and sea ice. And the movement can actually move the axis of the Earth herself! To explain which is which, Dr. Surendra Adhikari from JPL/Caltech tells Kevin, Jimmy, and Owen the difference. Using a NASA satellite, Dr. Adhikari, tells how he made his measurements that grabbed social media's attention last week. Since Jimmy's back from Boston after hanging with real life heroes, he tell the guys about the trip.

This episode of the Geology Flannelcast discusses Milankovitch Cycles, which are the main drivers of Earth's climate.

Kuzey Kutbu’ndaki (Arktik) buzun erimesi her geçen gün daha kötüye gidiyor. Buzun hacmi yıl boyu değişkenlik gösterir, kış ortasında zirveye yükselir ve genelde Eylül ayı gibi, yani yaz sezonu minimum seviyeye geriler. Son 1400 yılda, her Eylül ayında arta kalan Kuzey Kutbu buzul hacmi neredeyse sabittti. Ancak 1980'den beri bu buzun % 80’ini kaybetmiş durumdayız. Bir konuyu anlamamız lazım ki, o da 4,7 milyar yıldır ısıma ve soğuma anlamında birçok iklimsel doğal döngü olmuştur. Günümüzde Kuzey Kutbu’nda oluşan hadise doğal kaynaklı iklimsel döngü değildir,  biz insanların son yüzyılda yaktığımız fosil yakıtlarla birlikte bir trilyon tondan fazla karbonu atmosfere göndermemizin sonucudur. Pekala, nedir bu doğal döngüler?  Onlardan pek çok vardır. Hadi bunlardan biri olan Milankovitch döngülerine bakalım. Bu döngüler Dünya ve onun Güneş çevresindeki yörüngesi ile alakalıdır. Üç ana Milankovitch döngüsü vardır. Bunların her biri, Dünya'nın ne kadar güneş radyasyona maruz kalacağını, ve bu radyasyonun buza, karaya veya sulara ne zaman düşeceğini etkiler. İlk Milankovitch döngüsü şudur; Dünya'nın yörüngesi nerdeyse dairesel bir formdan hafifçe eliptiğe kayar. Bu durum 100.000 yıllık bir döngüde gerçekleşir. Dünya, Güneş’e yakınlaştığı zaman daha fazla ısı enerjisi alır, uzaklaştığında ise daha az. Şu anda Dünya'nın yörüngesi “nerdeyse dairesel” ve “hafif elips” arasındadır. Yani her takvim yılında Güneş'e olan mesafe değişimi yaklaşık 5,1 milyon kilometredir, bu da Dünya'ya varan güneş ışınımının % 6,8'lik bir fark göstermesine sebep olur. Dünya’nın yörüngesi en yüksek eliptikliğe kavuştuğu zaman, yerküreye varan güneş ışınımında % 23'lük fark oluşacaktır. Gezegenimize varan güneş radyasyonunu etkileyen ikinci Milankovitch döngüsü ise, Dünya'nın kuzey-güney yönünde yatan dönüş ekseni ile Dünya’nın güneş etrafında dönerken üzerinde bulunduğu düzlem arasındaki eğimdir. Bu eğim ise dikeyde 22,1º ile 24,5º arasında oynar. Bu döngü 41.000 senede bir tekrarlanır. Günümüzdeki konumumuzdan bahsedersek, kabaca ortalarda bir yerdeyiz -dikeyden 23,4º açıyla eğik durumdayız ve 22,1º ye doğru ilerliyoruz. Yaklaşık 11.800 yılında en düşük seviyeye ulaştığımızda, genel eğilim her iki yarımküre için de yazın daha az güneş ışınımına maruz kalma yönünde olacak iken, kışın daha fazla güneş ışınımı alacak ve genel olarak hafif bir serinleme olacaktır. Gezegenimizin güneş ışınımından ne kadar etkileneceğini etkileyen üçüncü Milankovitch döngüsünün anlaşılması biraz daha zordur. Buna ‘eksen sapması’ denir. Dünyamız Güneş etrafında dönerken, kuzey-güney yönelimli dönüş ekseni, dikeyde gerçekleştirdiği 22,1º ile 24,5º arasında sallanmaktan fazlasını yapar. Aynı zamanda —çok yavaş dönen devasa bir topaç gibi— döner gövdenin dönme eksenin savrulmasıyla çizilen 360º daireyi tarar, ve bu 26.000 yıl sürer. Böylece 4 Ocak’ta Dünya Güneş’e en yakın olduğu zaman,  Güney Kutbu (yani Antarktik)  Güneş’e doğru yönelmiştir. Şartlar şu an eşit olsa, güney yarımküre daha sıcak bir yaza sahip olur, çünkü daha fazla güneş ışınımına maruz kalır, fakat altı ay sonra daha soğuk kışlara sahip olur. Ve buna karşılık, kuzey yarımküre ise daha ılık bir kış ve serin bir yaza sahip olacaktır. Elbette “her şey” eşit değildir. Kuzey yarımkürede daha fazla kara parçası vardır, güney yarımküre ise daha fazla okyanusa sahiptir. Kuzey Kutbu, su üzerinde yüzen ve arazi ile çevrelenmiş buzdan oluşur. Güney Kutbu ise tam tersidir — sularla çevreli kara parçası üzerinde oturan buzdur. Bunların ne kadar karmaşık olduğunu görüyorsunuz, değil mi? Şu an içinde bulunduğumuz döngü içerisinde, son üç milyon yıldır mükerrer buzul çağları yaşandı. Bir buzul çağı sırasında buzulun kalınlığı üç kilometre olabilir ve hemen hemen tüm Kanada’yı kaplayabilir. Sibirya ve Avrupa'ya yayılabileceği gibi, nerdeyse bugünkü Londra'ya kadar ulaşabilir. Tabi ki buzu oluşturan su okyanuslardan geliyor ve bu sebepten ötürü geçmişte deniz seviyesi yaklaşık 125 metre daha alçaktı...
