Do you think climate change is impacting biodiversity more in the tropics than in temperate regions? You’re not alone - so did biologists. But nearly half of species in temperate zones are already facing local extinctions because of warming temperatures. ruththornton.substack.com/p/climate-ch...

Six regions remain in the eastern U.S. that could accommodate wolves, but they’re only found in one of them, the Great Lakes. Hear from experts about wolves’ precarious situation under the Endangered Species Act and why it’s not a purely biological question. ruththornton.substack.com/p/wolves-cou...
