Replacing some meat with microbial protein could help fight climate change
Just a 20 percent substitution could cut deforestation rates and land-use CO2 emissions by more than half by 2050, a new study suggests.

How some sunscreens damage coral reefs
In lab experiments, sea anemones and coral turned oxybenzone into a toxin activated by light. But helpful algae may provide a layer of protection.

How ancient, recurring climate changes may have shaped human evolution
Climate changes drove where Homo species lived over the last 2 million years, with a disputed ancestor giving rise to H. sapiens, a new study claims.

A UN report says stopping climate change is possible but action is needed now
We already have a broad array of tools to reduce global greenhouse gas emissions in half by 2030, a new report finds. Now we just have to use them.
