For the month of August, we're highlighting episodes from the 2023-2024 season of Energy Policy Now. We'll be back with new content, and a new season, on September the 10th. Climatologist Michael Mann discusses his new book on Earth's climate past, with insights into our climate future. --- (This episode was recorded on September 14, 2023) Renowned Penn climatologist Michael Mann's latest book, “Our Fragile Moment,” explores the history of climate change and the lessons it can provide into the trajectory of climate change today. The book is Mann's response to the phenomenon of “climate doomism” which, Mann writes, misrepresents the paleoclimate record to promote climate inaction. In the book, Mann seeks to set the paleoclimate record straight, and discusses how human agency remains our greatest tool in preventing the worst impacts of climate change. Michael Mann is Presidential Distinguished Professor in the University of Pennsylvania's Department of Earth and Environmental Science, and director of the Penn Center for Science, Sustainability and the Media. He is also a Faculty Fellow at the Kleinman Center for Energy Policy.

Looking at sediment under a microscope is a window into past environments and climates. In a dot of sediment, you may find thousands of microfossils - tiny remains of bacteria, protists, fungi, animals, and plants. Rajani Panchang, an oceanographer and micropaleontologist, uses microfossils from oceans, of tiny marine organisms, to interpret how the climate and environment may have been when they were alive. Such work gives us ideas about the chemistry and temperature of the ocean, ocean currents and wind patterns of the past. Paleoclimate research eventually feeds into reports that give us the large picture of climate change and our means of recovery. It starts with studying sediments.

What can shells tells us about marine paleoclimate? Shells and molluscs store a wealth of paleoclimate information. Molluscs build their shells with calcium carbonate from the sea water. Their shells record the sea water chemistry, which lets us decipher the changes that occurred in their environment. Paleoclimate scientist Devapriya Chattopadhyay studies mollusc fossils which help reconstruct the marine paleoenvironment. Her findings revealed that even periods of slight warming affected mollusc diversity in an area considered to be less affected by changes in the climate. In the context of present-day climate change, this paleoclimate research is considered to be very useful in bridging some knowledge gaps. In this episode of Imprints, Chattopadhyay talks about her fossil-hunting adventures, interesting discoveries and the people she encounters on the field. She also speaks about how infrastructure development could erase records of natural history and the challenge that India faces in setting up a museum for natural history.

The geologic record of Earth is an archive of data on the causes and effects of changing climates. As climate changes, it impacts everything from plants and animals to rocks and rivers. The study of ancient climates is paleoclimatology, and it’s important not only for our understanding of climate in the past, but also for teasing out what’s happening with our climate today and what we can expect for the future. In the news: tyrannosaur group, a chomped squid, horned crocs, and night dinosaurs. This episode, we’re joined by Dr. Rachel Lupien!

Imagine if you lived in a world where some humans evolved the ability to fly, use one hundred percent of their brainpower, or the ability to reproduce at twice the normal rate. These evolved humans would certainly have an evolutionary advantage over the rest of us, and likely outcompete us in the long-term. What if a similar situation happened around 541 million years ago? Around this time, in the late Neoproterozoic, the Ediacaran biota, mostly filter-feeding and immobile organisms, faced the threat of extinction from their more agile, burrowing, and mobile competitors that evolved during the late Ediacaran and early Cambrian. A mass extinction ensued, but the definite causes are still being debated. We talk to Associate Professor Marc Laflamme, an expert on Paleoclimate and Paleontology about this fascinating time period.  Primary Sources Discussed:  https://www.sciencedirect.com/science/article/pii/S0012825220304815

Today I am interviewing Sylvia Dee, an assistant professor at Rice University leading the Climate, Energy and Water Lab. Dr. Dee is a climate scientist specializing in atmospheric modeling, water isotope physics, and paleoclimate data-model comparison. In this conversation we discussed the intricacies of including proxy data in data assimilation products, climate modelling and inferring possible future rainfall changes from climates of the past.

The guest of this episode is Kaustubh Thirumalai, an assistant professor at the University of Arizona. We talked about him growing up and studying in India, and changing his path from chemical engineering to climate. We also talked a lot about networking in academia. The paper we discussed is about how sources of methane in the atmosphere from paleo records are related to orbital variability, and the implications for modern climate change. Learning all the things we need to take into account when analyzing paleo records was eye- opening…. And his spectral analysis of long paleo records is absolutely interesting and potentially applicable to other fields… so listen on!

What can the history of Earth's climate tell us about its future, and what is the relationship between climate change and the economy?

What can the history of Earth's climate tell us about its future, and what is the relationship between climate change and the economy?

In this interview with professor Richard Alley, from Penn State University, we speak about the climate of our planet in the past, and about how it is written in the ice of the polar ice caps or in the sediments of the bottom of the ocean. We speak about the predictive ability of climate models, about earthquakes triggered by glacial mass movement and about the role of CO2 in global warming. We conclude with some reflections about the future of energy production in our planet. Professor Alley visited Spain to receive the Fronteras del Conocimiento Award of the BBVA Foundation for Climate Change. We are grateful to the BBVA Foundation to provide us with the possibility of talking with professor Alley. This conversation was the basis for a radio show on paleoclimate and how ice provides techniques to study it. You can listen to it (in Spanish) here: http://www.ivoox.com/brujula-ciencia-s04e37-paleoclima-el-audios-mp3_rf_4723350_1.html This interview was recorded on June 22nd, 2015 at the headquarters of the BBVA Foundation in Madrid.

00:00:00 - Jason Head joins us to talk about Titanoboa, the largest snake ever found and subject a new documentary starring Dr. Head himself. Part 1 tackles the initial discovery and piecing together of the biology of the snake. We actually recommend watching the documentary (or play the game) first, but you're a smart person, you'll figure it out regardless. 00:27:29 - Some snakes function better in the water, some scientists podcast better with a drink. Charlie tries his hand at cider, Patrick calls back to an old-faithful Pinot Noir, and Ryan compliments his recently acquired Biere De Mars from Jolly Pumpkin. 00:31:28 - Trailer Trash Talk tangents into board game territory, i.e. anything to avoid talking about how bad Battleship looks. 00:43:50 - Part 2 of our interview with Dr. Jason Head finishes the story of The Infamous Biting of John Bloch, as well as discussing the paleoecological significance of this awesome find. We also ask about the process of having a documentary made about your work. All in all, a good time is had. 01:02:10 - PaleoPOWs are a lot like fossil snakes, easily lost to the rigors of time. Charlie has an iTunes review from an underaged fluffyraptor decrying his lack of ability to donate. We come up with an alternate, more collegiate use for the money. Speaking of money, Eric C. decides to set up a recurring donation, and Patrick is quick with the praise. And finally, Ryan has a question from Kyle H. concerning which scientific topic the guys would most like to see animated.   Thanks for listening and be sure to check out the Brachiolope Media Network for more great science podcasts!   Music for this week's show provided by: Crawling Snake King - The Doors Johnny Appleseed - Joe Strummer & The Mescaleros The Battle of Who Could Care Less - Ben Folds Five So Long - Guster

Ice on earth is sensitive to climate change and ice plays a role in climate change processes. Recent trends in the Greenland ice sheet provide an important example. Over the past two decades the extent of surface melt water on the ice sheet has increased. Inaddition, satellites have detected a decrease in the overall mass of the Greenland Ice Sheet. Paleoclimate is also discussed in this lecture, with a focus on climate over the last 5 million years. The mid-Pliocene was a particularly warm period from 3.3-3 million years before present. The Pleistocene was a more recent cold period ending with the Last Glacial Maximum about 14,000 years before present. In comparison, the Holocene (12,000 years ago to present) has been a relatively warm stable climatic period. Geomorphology is used to determine the extent of continental ice in the past.
