A new UCLA–NRDC report shows massive pricing disparities in who pays what for water from the #ColoradoRiverBasin. Some California urban water agencies shell out over $2,500 per acre-foot of surface water, while some irrigation districts pay $0—for the exact same water. ucla.in/4pC6ODH @nrdc.org

Been waiting for this to come out from colleagues Noah Garrison & Mark Gold of @uclaioes.bsky.social: The team investigated how much major suppliers spend on water from rivers and reservoirs in California, Arizona and Nevada. As covered by @ra-becks.bsky.social: calmatters.org/environment/...

It’s important that “people get information through channels they trust and see,” UCLA water researcher Greg Pierce tells the Washington Post. He calls for better flood warning systems as U.S. flood deaths rise. “We should invest in that, and we’re not right now.” @gregspierce.bsky.social

After multiple Waymo vehicles were set on fire during protests, the company pulled service across L.A. and much of S.F. UCLA professor Rajit Gadh told @sfstandard.com if torchings continue, companies may add sensors and cooling systems to protect their vehicles.

As cities race to adapt to climate change, they're demanding hyperlocal forecasts. But UCLA climate sciensist Alex Hall tells @Science.org the science behind these projections is far from settled: “It really is a mess right now.”

Watts residents led officials on a "toxic tour" to expose decades of pollution. UCLA loES PhD candidate Danielle Hoague, a researcher with the #BetterWattsInitiative, tells ABC7: "What's at stake is people's health,” with illegal dumping and contamination still impacting communities.

What are the long-term health effects of the LA Wildfires? UCLA researchers are working to find out—with help from the public. All LA residents are encouraged to join the #UCLAWildfireRegistry, a database of participants that will support research on physical and mental health impacts.

The carbon offset market could grow to $1 trillion — or collapse under its own weight. New research from leading scientists at UCLA, the Clean Air Task Force and Boston University shows why forest carbon credits need stronger standards to deliver real climate benefits.

👏 Marilyn Raphael, professor of geography and former IoES director, has been elected to the National Academy of Sciences—one of the highest honors a scientist can receive. She and 3 other UCLA faculty join a community of elite scholars and Nobel laureates.

What can cities learn from LA’s approach to clean energy and equity? A new UCLA study breaks down the data, decisions and trade-offs behind LA’s plan to reach 100% renewable energy by 2035–without leaving vulnerable communities behind. 🔋 More here: www.ioes.ucla.edu/article/what...

🧬 Have dire wolves truly been resurrected? “Probably not,” says UCLA’s Brad Shaffer. “Does it have some of their features? Yeah. And my guess is that’s as much as they hoped to accomplish.” He tells @Gizmodo.com it’s still ‘big accomplishment’ for conservation biology. gizmodo.com/has-the-dire...

💙🐻 Fun fact: my parents met at UCLA!—now I get to give a seminar there! Speaking @ #UCLA next week for the RUA Research Exchange! 🗓️ Apr 16 🕐 12pm PST 🔗 Zoom Link: lnkd.in/gb9cKae2 👉🏽 Second photo is of little me!—this moment’s a long time coming 💫 #RUA #BruinBaby @uclaioes.bsky.social

Kelp forests have flourished for more than 30 million years. But marine heatwaves—expected to become up to 16 times more frequent by 2100—could drive mass die-offs, a new UCLA study finds. Only 3% of the world’s kelp forests are highly protected.

UCLA ecologist @travislongcore.bsky.social spoke with California Builder & Engineer about light pollution at the Wallis Annenberg Wildlife Crossing. His team observed a barn owl using a “dark spot” over the crossing — early evidence that the design will support habitat connectivity.

Recycling just 40% of wastewater could transform the water outlook for 40M+ people across the Colorado River, says a new UCLA and @nrdc.org report. Some states are already doing it. “This is an entirely feasible solution”

Longer term, California and the West face serious water challenges due to climate change and overuse. Wastewater recycling could help, but states along the Colorado River aren't doing nearly enough of it, per a new report from UCLA: www.latimes.com/environment/... via @ianjames.bsky.social

UCLA report shows that if all 7 of the drought-plagued Colorado River Basin states recycled water as well as Arizona (or even 2/3rds as well as Nevada), they could save up to 30% of the shrinking river’s shortfall. newsroom.ucla.edu/releases/as-... Research by @uclaioes.bsky.social @nrdc.org

In a new report, UCLA researchers say California and other states should recycle more wastewater to help address the Colorado River’s chronic shortages. "Modest gains in water reuse could make an enormous difference." www.latimes.com/environment/... @uclaioes.bsky.social #CAwater

1 in 8 Californians now live in “high” or “very high” wildfire hazard zones—up 168% from 2011, per CalFire. UCLA climate scientist Daniel Swain says “weather whiplash” is a hidden factor; “It’s certainly relevant to what happened to LA this past winter.” @gristnews.bsky.social
