Feeling the heat: fossil-fuel producers linked to dozens of heatwaves

00:45 Attributing extreme heat events to major energy producers

Major energy producers increased the likelihood and intensity of heatwaves, according to research published in Nature. Using data from an international disaster database, a team developed a methodology to investigate how much anthropogenic climate change had influenced heatwaves. They conclude that many of these events would have been “virtually impossible” without climate change, and that nearly a quarter of the heatwaves recorded from 2000 to 2023 can be directly linked to the greenhouse-gas emissions from individual energy giants.

12:40 The growing resistance to the US war on science

Science in the United States is facing an increasing crisis, in the face of swinging cuts and President Donald Trump’s ongoing attack on anything with a connection to diversity, equity and inclusion. In the face of this crisis, many researchers are fighting back — we hear about some of their efforts, and what they think about their chances of success.
