Climate change is subjecting vulnerable people to temperatures that push their limits. In 2023, about 47,000 heat-related deaths are believed to have occurred in Europe. Researchers estimate that climate change could add an extra 2.3 million European heat deaths this century. That’s heightened the stakes for solving the mystery of just what happens to bodies in extreme conditions.
While we broadly know how people thermoregulate, the science of keeping warm or cool is mottled with blind spots. Researchers around the world are revising rules about when extremes veer from uncomfortable to deadly. Their findings change how we should think about the limits of hot and cold—and how to survive in a new world. Read the full story.

Whales are dying. Don’t blame wind turbines.
Whale deaths have become a political flashpoint. There are currently three active mortality events for whales in the Atlantic, meaning clusters of deaths that experts consider unusual. And Republican lawmakers, conservative think tanks, and—most notably—President Donald Trump (a longtime enemy of wind power) are making dubious claims that offshore wind farms are responsible.
But any finger-pointing at wind turbines for whale deaths ignores the fact that whales have been washing up on beaches since long before the giant machines were rooted in the ocean floor. This is something that has always happened. And the scientific consensus is clear: There’s no evidence that wind farms are the cause of recent increases in whale deaths. Read the full story.
