Pablo Saide discusses how fires can generate their own weather and that when they get to be so extreme that can result in fire-generated thunderstorms and other phenomena.
Huge pyrocumulonimbus clouds just formed over fires in the West. Here’s why they could become more common on a warmer planet. “If there is an increase in these clouds, the…
An episode of the series “Earth Focus,” which is co-produced by UCLA’s Laboratory for Environmental Narrative Strategies, or LENS, has won a Los Angeles Area Emmy Award. The episode, called “Coal Mining…
All I can say is, wow, what a remarkably prescient paper,” said Daniel Swain, a climate scientist at UCLA, noting that it was completed and submitted for publication prior to…
In California, the electric utilities’ infrastructure runs through highly flammable areas. “There’s just no question about that because we bring electricity long distance into the urbanized areas,” said Stephanie Pincetl,…
“I’m less convinced that recent events tell us that things are moving faster than projections have suggested,” Swain said. “But I am increasingly convinced that we’ve underestimated the impacts of…
“And if that layer under the cloud base is somewhat dry, as it often is out West, a lot of that water can evaporate before it actually hits the surface.…
A UCLA study published in Nature Communications shows definitively that abnormally heavy rain and snowfall events around the world are becoming more severe due to human-driven climate change. “These findings…
The intensity and scale of the floods in Germany this week have shocked climate scientists, who did not expect records to be broken this much, over such a wide area or…
Former Gov. Jerry Brown required Californians to conserve 25% of their water during the third year of the last major drought. State leaders have not yet taken that step during this…
In this episode of Slate’s “What’s Next: TBD,” UCLA climate scientist Daniel Swain discusses why it’s not too late to turn things around and what are the right questions to…
Scientists are mapping correlations between race, poverty and heat in cities, and suggesting solutions to reduce the dangers. In Los Angeles, researchers have calculated that two basic interventions — planting…
As fires propagate throughout the US west on the heels of record heatwaves, experts are warning that the region is caught in a vicious feedback cycle of extreme heat, drought…
Vegetation is at record-dry levels for this time of the year, and it is at least six weeks ahead of where it should be, said UCLA climate scientist Daniel Swain.…
President Biden’s plan calls for highway removal to right historical injustices and improve the health of people who live nearby. At least four bills in Congress would fund such efforts,…
Existing technology can support heavy-duty electric trucks that travel short distances, though longer trips still pose a challenge. “You can always keep waiting for the perfect technology to come,” Deepak…
Governor Gavin Newsom today hosted a virtual meeting with internationally renowned scientists and climate change experts, including IoES’ director Marilyn Raphael, to discuss California’s ambitious climate goals, efforts to protect…
“There is a clear human fingerprint on this particular extreme heatwave in the Pacific Northwest, and in general on extreme heatwaves everywhere in the modern era we’re living through,” said…
A new UCLA study links human activity to intensifying rainfall.”These findings further elevate the urgency of reducing greenhouse gas emissions to prevent even larger impacts down the road,” said Alex…
New research from Seol suggests elevated exposure to nitrogen dioxide from air pollution was linked with a greater risk of developing Parkinson’s disease. “We know that it is a disorder…
Now, UCLA ecologist Paul Barber and colleagues from UCLA and three other institutions have created a library of DNA “barcodes” that identify 605 species in the California Current, including 275…
Human activities, such as burning fossil fuels for transportation and electricity, have worsened the intensity of extreme rainfall and snowfall over land in recent decades, not just in a few…
Brad Shaffer, an evolutionary biologist at UCLA, has high hopes the wildlife crossing will reshape not just the landscape for its top predator but the character of Southern California. “From…
