Since 2018, thousands of hectares of German spruce forest have succumbed to a severe drought and an accompanying wave of bark beetle outbreaks.

It’s one of many examples of large-scale forest die-offs around the world.

Forests once deemed ironclad are suffering surprising die-off — and to predict the fate of the world’s woods in the face of climate change, researchers need to understand how trees die.

Sidewalks without a hint of shade. Heat radiating up from asphalt streets and down from walls.

Depending on the city, environmental scientist Angel Hsu says, its downtown can average 3 to 4 degrees Celsius hotter than the surrounding suburbs and countryside.

This is not just a matter of discomfort. The heat-island effect endangers the health of billions of people.

The good news: Excess urban heat isn’t inevitable.

Our bodies crave more food if we haven’t had enough protein, and this can lead to a vicious cycle — especially if we’re reaching for ultraprocessed instead of high-fiber whole foods. Entomologist and nutrition researcher Stephen Simpson tells @KnowableMag in a Q&A.
