On Thursday, Apr 16 at noon PT, I'll have a "lunch hour" livestream to discuss the already prolonged & severe marine heatwave affecting Pacific ocean near California. Also: are upcoming April showers connected to a West Pacific supertyphoon?

Winter rewind: When April across the Sierra literally looks more like February (Yosemite/Half Dome and Stateline/S. Lake Tahoe) w/ impressive 3 day totals. It is also the most April snow since 2022 according to @TahoeWeather. More opportunities may be lurking ahead...stay tuned. #CAwx 4/13/2026

California, let’s go!!! #BecerraForGovernor

Words have meaning, so when the Secretary of Defense declared "no quarter," he gave zero consideration to United States military members or ANY military members. This pilot needs more than thoughts and prayers, y'all.

New post on Weather West: As historic March heatwave finally fades, a brief cooler/wetter interlude will occur across the U.S. West in early April before warmth & dryness likely return. Also: a deeper dive into now record-low Western snowpack.

A good primer on the SAVE Act. #RadioFreeAmerica

I've been enjoying waking up to sun. Hate going back to the dark. And I don't need more light after dinner. I don't golf!

It's healthier to wake after sunrise with Standard Time, than to wake in the dark with Daylight Saving Time.

we reached the “no WMDs” phase in two days.

This week's cover @thelancet.com

I'll have a "late-breaking" livestream session tomorrow (Wed, Feb 18) at 2pm PT to discuss multiple topics, including: Recent switch to colder/wetter conditions (including news re: major avalanche) & updates re: EPA GHG regs & efforts to save NCAR. #CAwx

Doink!

No. No. No! This is critical research. It's not even centered on climate. It's solar physics! It's geomagnetic storms! It's space weather! It's sunspots! It's a research center needed for satellites and spaceflight!

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.

Doing our best to shop at stores that support DEI and share our values. Got an 8' Christmas tree at Costco today. It's super fresh and was only $76! We've seen similar trees on the lots for over $200. We also got a nice bottle of wine and some fresh Dungeness crab ($9.99/lb). Merry Christmas to us!

UC ANR helps Californians in all corners of the state adapt to climate change--and it's a team I'm personally proud to be part of. For #GivingTuesday, if you can, give to support this work: give.ucanr.edu

I’m gifting this article so you can read it without a subscription. www.nytimes.com/2025/11/12/u...

A newly released Jeffrey Epstein email says Trump “spent hours at my house” with one of Epstein’s victims. Other messages indicated Epstein believed Trump was well aware of the sexual predator’s illicit operation.

Epstein in emails: Trump knew about the girls. www.nytimes.com/2025/11/12/u...

This is actually good spin, or would have been. But the fact that the Democratic cave happened without even a coordinated, agreed-upon message like this indicates the depth of the leadership void.

What is the argument for voting for Democrats for harm reduction if the harm is not fucking reduced

Tonight’s Senate vote on the federal government shutdown should have been a time for strength. Instead we saw capitulation and a betrayal of working Americans. The American people need more from their leaders.

My statement on the proposed Senate deal

Musk immediately confirms Joyce Carol Oates' assessment.

Shapiro: He rose to some prominence by writing a book about growing up in Appalachia, where there are a whole lot of people who get SNAP. He made millions of dollars off telling their stories, and then he turned his damn back on those very people he likes to write about and claim as his own.

More people voted in New York City’s election this year than they have in 50 years. That’s a win for democracy, and a testament to @zohrankmamdani.bsky.social's inspiring campaign. Congratulations to the next mayor of the greatest city in the world. 🗽

New Yorkers have spoken and voted for change. Congrats Mayor-elect @zohrankmamdani.bsky.social!

You're going to want to buckle up before you read this crazy story. Can't wait for the Netfflix mini-series, hopefully with Patricia Arquette as MaryBeth

“We were here in the 1980s when the federal government threatened to take the California Coast and pollute it, drilling for oil, gas and now, for seabed minerals and they want to do that again,” said Santa Cruz Mayor Fred Keeley. 🔌💡 www.santacruzsentinel.com/2025/10/29/s...

we have a way for guys like this to fund the military it’s called “taxes” and clearly they should go up

It’s not his house. It’s your house. And he’s destroying it.

Today's Reliable Sources lead: Portland is not burning. Trump's rhetoric is totally divorced from reality. One way to prove it is by pairing Trump's words with the pictures... cnn.it/4q0hlJs

Editorial cartoonist Mike Luckovich questions whether Trump can distinguish between reality and fiction.

I can’t believe I’m watching interviews of city mayors talking about how they are coordinating with other mayors to discuss how to protect their residents FROM THE PRESIDENT OF THE UNITED STATES I know we are “used to it” but it is absolutely insane

Jayapal: It is a strange and bizarre time when we literally have a president thinking about plating the ballroom in gold—while he’s thrown 15 million Americans off healthcare, fired over 150,000 federal workers, and is threatening to fire even more if we go into a shutdown.

Explaining the G.O.P.’s Misleading Talking Point on the Looming Shutdown

Not true, Tom. In fact, this is about the 11,000 Minnesotans in your district and over 89k across the state looking at huge health insurance premium increases. Doesn’t that concern you?

“Winter Daylight Time” is permanent DST, now also called “Sunshine Protection”. It failed in the 1970s and 1940s. Remind your legislators to restore permanent Standard Time instead! www.votervoice.net/ditchDST/Cam...

On this day in 1974, from Texas: #OTD #DitchDST > Winter Daylight Time a failure… Going back to “nature’s time” [Standard Time] has several advantages, benefits of Daylight Time in winter are negligible.

A hazy Green Flash over Half Moon Bay. 9/26/2025

I am issuing an (un)official "cool cloud watching day" advisory for much of central & southern California, including the SF Bay Area by this evening. With mid-level instability, deep tropical moisture, a hot airmass, and offshore low pressure system all in place--things might get interesting. #CAwx

I have a dog who is more qualified to be giving medical advice than trump is. Just sayin'

Well, obviously Jimmy Kimmel was wrong to suggest that MAGA World was making a spectacle out of Charlie Kirk's death.

New Weather West post out on potentially widespread and significant thunderstorm outbreak later this week across much of California thanks to then-former Tropical Storm Mario's remnants. I discuss caveats re: dry lightning and more within... weatherwest.com/arch... #CAwx #CAfire
