Microclimatic Refugia in Mountain Valleys

Quick fact

Steep, shaded valleys in the Alps can be 3–5°C cooler than nearby open slopes, enough to keep many species within their temperature limits despite regional warming.

Why this is interesting

You’ve probably noticed that a shady side of a mountain can feel drastically cooler than the sunny side. But did you know these cool pockets could be the key to survival for many species as the climate warms?
