A massive, gushing river in the sky — a mile high, more than 300 miles wide, and carrying up to 15 times the amount of water in the Mississippi River — has drenched huge swaths of the West Coast.  UCLA’s Daniel Swain has been following the atmospheric river and reported that it  brought more snow to...

Scientists have just revealed the climate forecast for the year 2080 in hundreds of cities across North America, and — surprise! — it looks like it’s going to get a whole lot warmer in all of them. Alex Hall, director of the Center for Climate Science at UCLA, said the work represents an effective way...

Daniel Swain is a climate scientist at UCLA. In this Mercury News article, Swain discusses the “growing likelihood of an atmospheric river storm hitting California late next week, raising concerns that if a warm “Pineapple Express” barrels in with enough force, it could melt parts of the state’s big Sierra Nevada snow pack and increase...

Alex Hall is Professor in the Department of Atmospheric and Oceanic Sciences and Institute of the Environment and Sustainability and Director of the Center for Climate Science at UCLA. His research is focused on reducing climate change uncertainty at both regional and global scales. All five of the hottest years on record have occurred in the last five...

Daniel Swain is a climatologist at UC Los Angeles. In this article in SF Gate about powerful winds in San Francisco, Swain points to weather models indicating “this could be the strongest wind event in at least several years” in coastal Northern California.

Daniel Swain is a UCLA climate scientist, studying the physics, dynamics, and impacts of the Earth’s changing climate system. In this SF Gate article, Swain talks about the high pressure ridge in the Bay Area. “Nearly every winter tends to feature at least one weeks-long dry interlude,” says Daniel Swain, “The real question is whether...

Daniel Swain, a climate scientist at UCLA, weighs in on a new poll about public opinion on climate change.  “A new poll finds 74 percent of Americans say extreme weather in the past five years — hurricanes, droughts, floods and heat waves — has influenced their opinions about climate change.” For Daniel Swain the willingness...

A study by Neil Berg and Alex Hall, climate scientists are UCLA, was referenced in a story on how Cal Poly is adapting to climate change. “The amount of snow in California mountains has already decreased by 25 percent and is expected to increase by at least 60 percent according to University of California, Los...

UCLA climate scientist Daniel Swain, an assistant researcher at UCLA who publishes the California Weather Blog, said he expects “unusually warm, dry and quiescent weather” in Northern California for weeks, perhaps until mid-February. “It does appear that California will rapidly dry out after this week’s storms and will enter a prolonged warm, dry period for...

Daniel Swain, a climate scientist at UCLA, writes about the rain storms this week in LA. 

IoES Center for Climate Science director Alex Hall talks with USA Today about the role of climate change in California wildfires and Atlantic Hurricanes.

Daniel Swian is a climate scientist at UCLA. As a climate scientist, he studies the physics, dynamics, and impacts of the Earth’s changing climate system. In this SF Gate article, he explains what common weather phrases actually mean.
