Yesterday, the U.S. Congress approved President Donald Trump's so-called 'Big Beautiful Bill'. This controversial federal budget is set to defund a huge proportion of the nation's climate and environmental science - what will the impacts be for America, and for global efforts against the climate crisis?

Bertie spoke to John Holdren, who served as President Barack Obama's Director of the Office of Science and Technology Policy from 2009-2017, becoming the longest-serving Science Advisor to the President in U.S. history. He is now a Research Professor of Environmental Policy at Harvard University's Kennedy School of Government.

In 2022, Gustavo Petro became the first left-wing candidate to win the Colombian presidential election. During his election campaign, Petro pledged to end the granting of new oil and gas exploration contracts, a commitment his government has so far succeeded in maintaining.

This week, Alasdair speaks with third-year doctoral student Guy Edwards who has interviewed over 50 people - from former government ministers to academics and industry representatives - about the impact of Petro’s pledge on Colombia’s energy transition.

Guy and Alasdair discuss what the pledge entails, how it was received by the fossil fuel industry and right-wing media and what will likely become of it following fresh presidential elections next year.

Guy Edwards is a PhD candidate in International Relations at the University of Sussex and a member of the Working Group on Natural Resources, Energy and Climate Obstruction in the Global South of the Climate Social Science Network

Germany's 2025 federal election saw the far-right Alternative für Deutschland (AfD) double its support to 20.8%, becoming the second largest party, while the Green Party fell from 14.8% to 11.6%. The AfD denies climate science and opposes environmental policies on economic grounds.

This week, Alasdair interviews academic Felix Schulz, whose recent research has examined public attitudes toward climate policy across six countries - three in the global north and three in the global south.

The research found that core values – particularly those derived from neoliberalism and free-market ideology – are more effective than socioeconomic factors in indicating how people will respond to climate policies.

Felix and Alasdair discuss how neoliberal thinking has shaped public opinion, why climate policy must integrate social and economic considerations, and how job security concerns in industrial roles affect political support for climate action.

Felix Schulz is a postdoctoral research fellow at Lund University researching public opinion and climate policy.
