Andrew Gray, an associate professor of watershed hydrology at UCR, weighs in on the threats to life and infrastructure posed by fast-moving debris flows, and how residents can best respond.

Many phone apps offer general but nonspecific information about airborne particles. To help increase public safety amidst the LA fires, UC Riverside scientists are making new, real-time, advanced air pollutant measurements available to the public.

UC Riverside climate scientist Francesca Hopkins explains how carbon emissions from human activities turn into conflagrations, and she has some ideas about making urban landscapes more resilient.

Southern Californians are chronically being exposed to toxic airborne chemicals called plasticizers, including one that’s been banned from children’s items and beauty products.

Several Southern California communities are being hit with smoke from the huge Line Fire in the San Bernardino Mountains. UC Riverside experts on environmental pollution describe what we’re breathing.

Three UC Riverside faculty experts weigh in on how the extreme summer heat affects our flora.

New research shows that California’s Central Valley, known as America’s breadbasket, gets as much as half of its groundwater from the Sierra Nevadas. This is significant for a farming region that, in some parts, relies almost entirely on groundwater for irrigation.

A new study greatly reduces uncertainty in climate change predictions, a move economists say could save the world trillions in adaptations for a hotter future.

Lack of rainfall is not the only measure of drought. New UC Riverside research shows that despite a series of storms, the impact of drought can persist in streams and rivers for up to 3.5 years. There are two measures of drought in streams. One measure is the total water...

UC Riverside scientists are taking a modern approach to studying a murky subject — the quantity, quality, and sources of microplastics in Los Angeles County’s urban streams.

Using a new detection method, UC Riverside scientists found a massive amount of methane, a super-potent greenhouse gas, coming from wildfires — a source not currently being accounted for by state air quality managers.

Water in California’s Central Valley contains enough manganese to cause cognitive disabilities and motor control issues in children, and Parkinson’s-like symptoms in adults.

UC Riverside researchers have identified tiny organisms that not only survive but thrive during the first year after a wildfire. The findings could help bring land back to life after fires that are increasing in both size and severity.

New UC Riverside research suggests nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere, where it can contribute to climate change.

New research from the University of Quebec declares coffee pods are “better for the planet than filtered brew.” Here to weigh in on the matter is UCR's Andrew Gray, who studies the movement of plastic pollutants through the environment.

University of California scientists have a new way to demonstrate which neighborhoods are most affected by air pollution from vehicle emissions. Their technique could help ensure people most affected by pollution will benefit from efforts to reduce it.

The Salton Sea, California’s most polluted inland lake, has lost a third of its water in the last 25 years. New research has determined a decline in Colorado River flow is the reason for that shrinking.

New UC Riverside research reveals that items in litter typically originate less than two miles from where they’re found — and unless humans remove them, most of these items will never leave the environment.

Wildfires don’t stop being dangerous after the flames go out. Even one modest rainfall after a fire can cause a deadly landslide, according to new UC Riverside research. “When fire moves through a watershed, it creates waxy seals that don’t allow water to penetrate the soil anymore,” explained environmental science...

A new UC Riverside study finds that climate change will have a devastating effect on the greater Palm Springs area’s dominant industry — tourism. Thousands known as “snowbirds” flock to the region annually from elsewhere in the country to escape freezing winters. However, due to climate change, the number of...
