(Conversation recorded on July 30th, 2024)   The science surrounding our planet's dynamic and complex climate can be difficult to understand, and perhaps even more challenging to decipher what the actual realities and trajectories are among so much media coverage. Yet the study of Earth's systems has been ongoing for decades, with a majority of scientists reaching a consensus on the realities of human-driven global heating.  In this episode, ocean and climate physicist Stefan Rahmstorf joins Nate for an overview on the most common questions and misconceptions concerning the state of the climate, including the nuances of what our future planetary home might look like.  How can carbon dioxide – which makes up such a small percentage of the atmosphere –  have such a large effect on the temperature of the whole planet? Why does warming have such huge ripple effects across the biosphere –  from ocean currents and wind patterns to extreme weather and wildfires? What do projections for the future tell us about the survivability of some of Earth's most populated regions – and how can communities and nations prepare and mitigate these challenges amid many other converging crises we face?    About Stefan Rahmstorf: Stefan Rahmstorf is Co-Head of the Research Department on Earth System Analysis of the Potsdam Institute for Climate Impact Research (PIK) and Professor of Ocean Physics at the University of Potsdam. His research focuses on paleoclimate, ocean circulation, sea level, extreme weather events and Earth System modeling.  After working at the New Zealand Oceanographic Institute and the Institute of Marine Science in Kiel, Stefan Rahmstorf joined PIK in 1996. From 2004 to 2013 Stefan Rahmstorf advised the German government as a member of its Advisory Council on Global Change (WBGU). He is not only an outstanding and highly cited scientist but also a sought-after science communicator and speaker, winning the Climate Communication Prize of the American Geophysical Union in 2017.    Show Notes and More Watch this video episode on YouTube   ---   Support The Institute for the Study of Energy and Our Future Join our Substack newsletter Join our Discord channel and connect with other listeners  

The Prime Minister of Barbados, Mia Mottley, has been raising awareness of the impact that climate change is having on small island nations like hers – from the Caribbean to the Indian Ocean, right across to the Pacific Ocean. In addition to facing more extreme weather and temperatures, these islands also have to contend with the threat posed by rising sea levels – which for some islands, is existential. In this episode, Qasa Alom speakers to reporters in Fiji and The Maldives about what small island nations can do to survive. Guests: Dr. Nadya Vinogradova Shiffer, Director of the Ocean Physics program at NASA Dr. Rosanne Martyr-Koller, Coastal Hazards and Adaptation Scientist at Climate Analytics Shahudha Mohamed, on-the-ground reporter in the Maldives Tim Vula, on-the-ground reporter in Fiji Producer: Ben Cooper Researcher: Octavia Woodward Series Producer: Simon Watts Editor: China Collins Sound Engineers: Hal Haines and Rod Farquhar Production Coordinators: Debbie Richford and Sophie Hill

Why is the deep ocean cold? And why does this matter for global warming?Doing the maths with pipes and plumbing, not computers, we explore how processes that keep the deep oceans at frigid Arctic temperatures also determine how fast the world is warming in response to rising greenhouse gas concentrations – and also explain why it would be so difficult to say when the warming would stop even if we were to stabilize greenhouse gas concentrations at today's levels forever.A lecture by Myles Allen recorded on 31 January 2023 at Barnard's Inn Hall, London.The transcript and downloadable versions of the lecture are available from the Gresham College website: https://www.gresham.ac.uk/watch-now/ocean-zeroGresham College has offered free public lectures for over 400 years, thanks to the generosity of our supporters.

A team of NIWA scientists will board the research vessel Tangaroa today for a six-week voyage to Antarctica. Their mission is to better understand the ecosystem and ocean physics in the Ross Sea, as well as assess the impacts of climate change. Lauren Crimp spoke with some of the team getting ready for the adventure.

Welcome to a Cosmos Insights podcast, where we talk to scientists in Australia about the impact of their work.This year's Prime Minister's Prize for Science has gone to a mathematician who wondered how much heat is contained in a kilogram of seawater, while he was swimming in freshwater in Boston.Trevor McDougall AC, Scientia Professor of Ocean Physics in the School of Mathematics and Statistics at the University of New South Wales, has received the Prime Minister's Prize for Science, recognising “his transformative impact in the study of oceanography and ocean thermodynamics. “Today Cosmos journalist Imma Perfetto talks to Scientia Professor McDougall about his work. Find the science of everything at the Cosmos Magazine websiteSubscribe to Cosmos Magazine (print) or the Cosmos WeeklyWatch and listen to all our Cosmos BriefingsSpecial 10% discount on Cosmos magazine print subscriptions (1 or 2 year), or 1 year Cosmos Weekly subscriptions for Cosmos Briefing podcast listeners!  Use coupon code COSMOSPOD in our shop. 

This episode is all about how the ocean works. It is a LOT of physics, so be prepared for a ramble of science talk. However, this does not guarantee boredom but a lot of new facts. We talk about how the ocean affects the whole Earth, and what ridges are.  IG: @teenup.podcasthttps://linktr.ee/Teenup.podcast

This sea week Our Changing World joins Dr. Kim Currie on the Munida transect time-series - a long running investigation of how the chemistry of the oceans off New Zealand is changing.

Water is essential for life – that we know. But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life. Ice is more than a repository for water that would otherwise raise sea levels. It's part of Earth's cooling system, a barrier preventing decaying organic matter from releasing methane gas, and a vault entombing ancient bacteria and other microbes.  From the Arctic to the Antarctic, global ice is disappearing. Find out what's at stake as atmospheric CO2 threatens frozen H2O.  Guests: Peter Wadhams- Emeritus Professor of Ocean Physics at Cambridge University in the U.K. and the author of A Farewell to Ice: A Report from the Arctic Eric Rignot- Earth systems scientist, University of California, Irving, senior research scientist, NASA Jet Propulsion Laboratory Åsmund Asdal- Biologist, Nordic Genetic Resource Center, coordinator for operations and management of the Svalbard Global Seed Vault, Svalbard, Norway John Priscu- Polar biologist, Montana State University Originally aired August 14, 2017   Learn more about your ad choices.

Water is essential for life – that we know. But the honeycomb lattice that forms when you chill it to zero degrees Celsius is also inexorably intertwined with life. Ice is more than a repository for water that would otherwise raise sea levels.

Gabe & Rick interview Dr. Peter Wadhams of Cambridge University on his latest book “A Farewell to Ice”.  Dr. Wadhams is the UK’s most experienced sea ice scientists. He was Director of the Scott Polar Institute in Carnbridge 1987–92 and Professor of Ocean Physics at Cambridge University 1992–2015 and currently at the Polytechnic University of the Marche, Ancona, Italy.He has made more than 50 expeditions to both polar regions.

Rogue waves are rare, massive waves and Craig Stevens explains that although 'we know one when we see one' we don't understand how they form.

This week we speak to Professor Peter Wadhams, Professor of Ocean Physics, and Head of the Polar Ocean Physics Group in the Department of Applied Mathematics and Theoretical Physics, at the University of Cambridge. Prof. Wadhams is an expert in Arctic sea-ice, and is a review editor for the physical sciences component of the upcoming 2014 IPCC (or Intergovernmental Panel on Climate Change ) Fifth Assessment Report. We discuss the precarious nature of the Arctic Sea-Ice, the end of summer ice altogether, the problems with the IPCC reports, climate tipping points, the release of massive quantities of methane into the atmosphere, and likelihood of Southern Europe turning into desert in this century. Enjoy!
