California experienced record rainfall this year, and may have even made headway against the state’s historic drought. Now that lush landscapes abound and spring is upon us, what does this mean for allergy sufferers?
This vernal equinox — the first day of spring — flora and fauna from Palos Verdes to the Yosemite Valley have been rejuvenated by a historically wet, snowy winter.
The UCLA study has important implications in an era of climate change.
Professor Alex Hall’s research shows that, as temperatures warm in the Sierra Nevada, a deluge could overwhelm California’s patchwork network of dams and reservoirs that currently supplies 60 percent of the state's water.
To counter likely cuts in federal funding for research into climate change and energy innovation, California’s government must fill the gap.
New research shows that a collapse of an ice sheet 14,000 years ago in what is now western Canada triggered a reorganization of the jet stream in a century — a geological blink of an eye.
UCLA scientists are studying the Sierra Nevada's climate future using a technique to create simulations to predict outcomes under different circumstances and help them understand the physical reasons for the projected changes.
From the capuchin monkeys of Costa Rica to the Los Angeles area's mountain lions, UCLA experts are developing new techniques and advancing knowledge.
L.A.’s only species of newt is showing signs of severe distress, troubling researchers and raising questions about the impacts of the drought and climate change.
Researchers found the association between ozone and mortality began at 35 parts per billion.
Robinson shared the story of her awakening to the global impact of climate change on the world's impoverished countries and communities at a lecture hosted by the UCLA Luskin School of Public Affairs Tuesday.
Global climate models vary in how much they show rain and other precipitation changing due to climate change. UCLA researchers discovered a way to reduce these differences by 35 percent.
All eyes are on Paris as the 2015 UN Climate Conference begins. California is well-represented, with many from the state participating, including five UCLA faculty and seven students.
In show of support for action at upcoming global climate talks, UCLA and UC pledge to combat climate change.
UCLA environmental professors Magali Delmas and Susanna Hecht are among the climate experts, politicians and industry leaders gathering in San Diego today for a University of California climate change summit.
At a "Thinking L.A." event co-hosted by UCLA and Zócalo, four panelists discussed the importance and difficulty of implementing desalination plants, water-recycling facilities and other tools to help California make better use of its water resources.
Researchers from UCLA and the Jet Propulsion Laboratory found that extra heat from greenhouse gases has been trapped in the subsurface waters of the Pacific and Indian oceans.
New research sheds light on the Earth’s climate over geologic time scales.
Despite progress, dirty air and water are just the beginning of the region's environmental troubles. The findings, which are believed to be the most comprehensive environmental report card for any region in the nation, show the county needs tutoring to bring up its grades.
UCLA researchers looked at 22 indicators to determine grades in six main categories — water, air, ecosystem health, waste, environmental quality of life, and energy and greenhouse gases.
Expanding customer access to energy data can bring cleaner, more efficient power to Californians, save money and boost emerging clean technologies, according to a new report by the Climate Change and Business Research Initiative, a partnership between UCLA and UC Berkeley schools of law.
Climate model simulations of the 21st century show little change in total precipitation, but more rain instead of snow, posing flooding risk and shortening chance to capture water.
A UCLA environmental law clinic coaches students to become legal advisers and official delegates to the annual United Nations climate conference
At a climate change conference on campus today, UCLA researchers and other speakers are discussing the challenges facing cities around the world.
UCLA atmospheric scientists were instrumental in the creation of the Santa Ana Wildfire Threat Index, which will help classify the fire threat potential of the Santa Ana winds.
