This Earth Month, UCLA experts share concerns about summer heat, from a potential El Niño to longer heat waves, and risks of atmospheric sulfur injections.

UCLA professor David Eisenman offers advice on how to stay cool and check on others during elevated temperatures.

UCLA Fielding School’s Kirsten Schwarz co-leads a study to analyze, redesign and cool school landscapes.

ShadeLA aims to expand urban tree canopy and shade infrastructure, building heat resilience for Angelenos.

A new approach uses low-cost, scalable, transparent and infrared-reflective surfaces and hydronic panels.

The longest and rarest heat waves — which can last for weeks — show the greatest increase in frequency.

A new tool pinpoints where shade is lacking across 360-plus cities and towns.

A group of UCLA students is making it their mission to understand how heat impacts our bodies, communities and planet.

UCLA climate scientists’ analysis links climate change to about a quarter of the extreme vegetation dryness when the Palisades and Eaton fires began.

New research links intensifying wet and dry swings to the atmosphere’s sponge-like ability to drop and absorb water.

California chapparal fire burns into urban Ventura County, showing need for strategies beyond fighting ‘forest’ fires.

Signals from La Niña suggest we’re in for a hot fall, says UCLA atmospheric scientist and statistician Karen McKinnon.
