Disappearing lakes and AI are helping scientists map Arctic permafrost thaw in near‑real time

The abrupt disappearance of a lake is one clear sign that the ice below is melting, and a clue to wider permafrost changes.

Beavers and oysters are helping restore lost ecosystems with their engineering skills – podcast

Restoring entire ecosystems is a difficult and expensive process. Thankfully, certain species, called ecosystem engineers, can make restoration easier. Gaining social and political support is critical too.
