World leaders have gathered in Egypt this week to begin climate talks at the 27th Conference of the Parties. However, there are still outstanding questions about who should pay for climate change losses and damages. Vulnerable countries hit hardest by climate change are asking the wealthier countries most responsible for these damages for compensation.

Climate change correspondent Lauren Sommer joins Emily Kwong to talk about this debate — and the case one island nation is making to seek payment.

The Congo Basin is home to the world’s largest peatland. Simon Lewis, Professor of Global Change Science at UCL and the University of Leeds, tells Roland how peatlands all around the world are showing early alarm bells of change. From the boreal Arctic forests to the Amazon, Simon helps us understand how they could action huge change in the climate. Simon is joined by Dr Ifo Averti, Associate Professor in Forest Ecology at Universite Marien Ngouabi in the Congo who helps us understand what this landscape is like.

Hurricane Ian, which recently caused devastating damage to Cuba and the United States, may signify a growing trend of increasingly powerful storms. Karthik Balaguru, climate and data scientist at the Pacific Northwest National Laboratory, explains how climate change is causing hurricanes to rapidly intensify, making them faster and wetter.

On Sunday 6th November, COP27 will begin in Sharm El-Sheikh, Egypt. Dr Debbie Rosen, Science and Policy Manager at CONSTRAIN, breaks down some of the jargon we might hear throughout the conference.

We know the Earth's atmosphere is warming and it's thanks to us and our taste for fossil fuels. But how quickly is this melting the ice sheets, ice caps, and glaciers that remain on our planet? That's what listener David wants to know.

With the help of a team of climate scientists in Greenland, Marnie Chesterton goes to find the answer, in an icy landscape that's ground zero in the story of thawing. She discovers how Greenland’s ice sheet is sliding faster off land, and sees that the tiniest of creatures are darkening the ice surface and accelerating its melt.

CrowdScience explores what we're in store for when it comes to melting ice. In the lead-up to yet another UN climate conference, we unpack what is contributing to sea level rise – from ice sheets in Greenland and Antarctica, to melting mountain glaciers and warming oceans. There's a lot of ice at the poles. The question is: how much of it will still be there in the future?

Research Professor and climate scientist Jason Box from the Geological Survey of Denmark and Greenland shows us how much ice Greenland we've already committed ourselves to losing, even if we stopped burning all fossil fuels today. His team, including Jakob Jakobsen, show us how these scientists collect all this data that helps feed climate models and helps us all to understand how quickly the seas might rise.

Professor Martyn Trantor from Aarhus University helps us understand why a darkening Greenland ice sheet would only add to the problem of melting. And climate scientist Ruth Mottram from the Danish Meteorological Institute breaks down how the ice is breaking down in Antarctica and other glaciers around the world.

In 1859, Charles Darwin published On the Origin of Species, a book about the evolution of non-human animals by natural selection. In its wake, a political idea arose — eugenics. Reading Darwin's book, Sir Francis Galton proposed that humans should be bred to give more "suitable" characteristics a "better chance of prevailing." Today, producer Rebecca Ramirez talks to Adam Rutherford about his new book, Control: The Dark History and Troubling Present of Eugenics, which traces the inextricable link between political ideology and science, and the enduring shadow of eugenics.

The Congo Basin is home to the world’s largest peatland. Simon Lewis, Professor of Global Change Science at UCL and the University of Leeds, tells Roland how this peatland acts as a huge carbon sink and how climate change could result in these carbon stores being released.

Katie Wu is a cat person. She has two of them: twin boys named Calvin and Hobbes. But up until grad school, she couldn't be anywhere close to a cat without her throat tightening and her nose clogging up. In a stroke of luck, Katie's cat allergy suddenly disappeared. The reasons for her night-and-day immune overhaul remain a mystery.

In this episode, Katie walks host Aaron Scott through the dynamic world of allergies and what it reveals about our immune systems. Calvin and Hobbes make cameo appearances.

Political economist and journalist Will Hutton, author of the influential 1995 book The State We’re In, offers a state of the field report on the social sciences in this Social Science Bites podcast. Hutton, who was appointed in 2021 to a six-year term as president of Britain’s Academy of Social Sciences, addresses various critiques of modern social science – especially in its British incarnations -- from host David Edmonds.

As defined by the academy that he now heads, “social science is the understanding of society in all its dimensions,” and encompasses the societal, economic, behavioral and geospatial sciences. Despite that broad remit, the first question posed is whether social and behavioral sciences take a back seat to the natural sciences in the public imagination.

Hutton, for his part, says no – although he does see them not always getting their due. He notes that in combatting the COVID-19 pandemic, yeoman’s work was conducted by social and behavioral science. “It wasn’t called social science, but it was driven by social science.” The same, he continues, is happening as Britain confronts its economic demons.

“Academic prowess is a kind of team,” he details. “You need your humanities, you need your physical scientists, your natural scientists, your medical scientists and your social scientists on the pitch. Sometime the ball falls to their feet and you look to them to make the killer pass.”

One thing that might help in achieving that overdue recognition, he explains later, would be if the social sciences themselves shared their commonality as opposed to denying it. “[T]he Academy of Social Science was established 40 years ago, because we felt that good as the British Academy is, it couldn’t represent humanities and social science co-equally. Social science needed its own voice. Four decades on, I would say that social science’s standing in the world is higher than it was 40 years ago. But if [a score of] 100 is what you want to get to, we probably haven’t gotten beyond 20 or 30.”

Impacting society, meanwhile, is how the sciences must improve their score (although Hutton acknowledges the vagaries of what impact looks like by saying “I’m not willing to castigate people if it looks as if what they are immediately doing is not impactful or having an impact.”) Asked what he sees as the “most fundamental issue” social science should tackle straightaway, Hutton offers four broad avenues to move down: Economics, governance, change behavior to keep the planet in good shape, and constructing a civil society of institutions that serve both individual and community needs.  Among those, he concludes, “I think combining ‘the we and the I’ is the most important thing that social science can do.”

Hutton’s wide-ranging answers follow from a wide-ranging career. He served as editor-in-chief of The Observer newspaper, was chief executive of the then Industrial Society, was principal of Hertford College, Oxford from 2011 to 2020, and has authored a number of bestsellers since The State We’re In: Why Britain Is in Crisis and How to Overcome It. Those books include 2008’s The Writing on the Wall: China and the West in the 21st Century, 2011’s Them and Us, 2015’s How Good We Can Be, and 2018’s Saving Britain: How We Can Prosper in a New European Future (written with Andrew Adonis).
