Stronger Rains in Warmer Climate Could Lessen Heat Damage to Crops, Says Study
Intensified rainstorms predicted for many areas in the United States as climate warms could more efficiently water some major crops, which would at least partially offset projected yield declines caused by rising heat itself.

More Intense Non-Tropical Storms Causing Increased Rainfall in U.S. Southeast
In the Southeastern United States, the increasing amount of rain during hurricane season is coming not from hurricanes but from non-tropical storms created by weather fronts, new research finds.

Warming Climate Could Abruptly Increase Rain in Africa’s Sahel
Climate change could turn one of Africa’s driest regions wet, according to a new study. Scientists have found evidence in computer simulations for a possible abrupt change in the Sahel, a region long characterized by aridity and political instability. In the study, just published in the journal Earth System Dynamics, the authors detected a self-amplifying…

In a Warmer World, Expect the Wet to Get Wetter, and the Dry, Drier
As the world warms due to human-induced climate change, many scientists have been projecting that global rainfall patterns will shift. In the latest such study, two leading researchers map out how seasonal shifts may affect water resources across the planet.
