Understanding Tropical Rainfall Projections Under Climate Change

by Suzana Camargo 11 February 20208 March 2022

A new mechanism explains changes in the probability distribution of tropical rainfall, which is not expected to change uniformly in a warming climate.

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.

Atacama Desert’s Unprecedented Rains Are Lethal to Microbes

by Katherine Kornei 12 November 201812 April 2022

Rainfall in the driest parts of Chile’s Atacama Desert in 2017 resulted in hypersaline lagoons that killed the majority of microbes adapted to millions of years of arid conditions.

The Acid Tongue of Climate Change Strikes Our Streams

by Ankur R. Desai 5 October 201821 March 2022

Clear air policies have led to dramatic reductions in acid rain and improved ecosystem health, but it now appears that climate change could counteract those gains.
