Climate-friendly farming strategies can improve the land and generate income for farmers

Farmers can help slow climate change by mixing native grasses into croplands, restoring wetlands and raising perennial crops. These strategies also conserve soil and water and build new markets.

Harvard chemist: Permafrost N2O levels 12 times higher than expected

A recent study shows that nitrous-oxide emissions from thawing Alaskan permafrost are about 12 times higher than previously assumed. About a quarter of the Northern Hemisphere is covered in permafrost, which is thawing at an increasing rate. And, even though researchers are monitoring carbon dioxide and methane, no one seems to be monitoring N2O, the most potent greenhouse gas.
