Accounting for the Fact that Snow Falls Slower than Rain

by Alessandra Giannini 26 August 201911 August 2022

When calibrating satellite observations with ground-based ones, estimated precipitation rates are improved by considering that snow takes longer to fall compared to rain.

Past Climate Sensitivity Not Always Key to the Future

by Terri Cook 13 August 201924 March 2023

New research suggests that changes in continental configuration, solar brightness, and background atmospheric carbon dioxide levels all conspire to drive Earth’s climate sensitivity over geologic time.
