Restoring former prairies that have been plowed under for farming delivers land, wildlife and climate benefits. But a new study finds that the weather plays a surprising role.

The current state of our climate shouldn't be dismissed as a 'new normal'. The hard truth is many of our ecosystems will not recover from the damage.
Populations of plankton are in decline. If we push this critical foundation of the marine food chain to extinction, we could cripple ecosystems for millions of years.
