A high-amplitude flow pattern, characterized by near-record strength ridging and troughing (respectively) over the western and eastern U.S. and a very wavy jet stream, will bring a progression of notable weather to North America in the coming days.

“People are living with wolves and wolves are living with people. That’s why we’re talking about what mix of tools we’re going to use now,” Arthur Middleton @natureatcal.bsky.social tells @kurtisalexander.bsky.social

A better world is possible

For those confused by state of play on SNAP right now: You're not alone Yesterday, *before* SCOTUS paused order telling Trump admin to send out SNAP $$, a handful of states rushed to issue full SNAP benefits to at least part of their caseload. This includes CA, OR, WA, MI, and WI—all blue states (🧵)

Salmonella is notoriously difficult to get rid of, Maurice Pitesky @ucdavisvetmed.bsky.social & @ucanr.edu told @susrust.bsky.social. It can be introduced to flocks from wild animals, such as birds, rats, mice and other wildlife.

On the need for adaptation, @weatherwest.bsky.social agreed with Gates: The climate community does tend to focus on mitigation at the expense of adaptation, “whereas we really have to be doing both as much as we possibly can,” Swain said. Via @theenergymix.com www.theenergymix.com/gates-climat...

Groundwater market development has faced significant hurdles, such as determining allocations and resistance to trade due to fears of consolidation and the loss of small-scale farming. As a result, progress has been minimal. #cawater mavensnotebook.com/2025/11/06/g...

“Our understanding of barriers to this work is increasingly nuanced, you see that reflected in this Executive Order, with impactful tweaks to existing policy and strong agency directives that continue to elevate & prioritize beneficial fire,” said Lenya Quinn-Davidson @ucanrfirenetwork.bsky.social

The memo from a “very influential person who controls a lot of money” hinges on “inarguably a false binary” between a world where everything is fine and “literally the end of the world”, said @weatherwest.bsky.social @ucanr.edu via @dharna.bsky.social @theguardian.com

Earlier this week, @sammyroth.bsky.social talked about the #GatesMemo with climate scientists @kimcobb.bsky.social, @hausfath.bsky.social, @katharinehayhoe.com & @weatherwest.bsky.social. Watch the video here 👇

Wine grape growers uproot vineyards “Fresno County lost the largest proportion of acreage in the state: More than 6,000 acres, or an 18% reduction.” 🍇

Hybrid wine grape varieties bred by UC Davis to be resistant to Pierce's disease are off to a good start www.latimes.com/food/story/2...

MacKenzie Scott gave $38 million to Spelman College, an all-women’s historically Black college, and another $38 million to Clark Atlanta University, the first historically Black university in the US to confer graduate degrees. This is her second time giving to both schools.

Quick Weather West update today for sake of discussing fairly strong atmospheric river that will arrive in NorCal Tue-Wed, bringing widespread rain, gusty winds, and maybe isolated t-storms. Warm still, though, so Sierra rain vs snow, & dry in SoCal. #CAwx

It turns out that rocks might help fight climate change. UC Cooperative Extension scientists are studying enhanced rock weathering — adding pulverized rock dust to farm fields — to see how much CO₂ it can pull from the air while enriching soils. @ucdavis.bsky.social ➡️ bit.ly/4oOH0mK

I just recorded a short video--essentially an updated version of my social media threads--on the Bill Gates climate memo. Despite agreeing with some points therein, I still think its framing is fundamentally flawed and thus also its key conclusions.

LIVE or online: Daniel Swain @weatherwest.bsky.social @ucanr.edu to speak on extreme weather events Nov. 5 in Irvine. Join him for “Climate Change Through the Lens of Increasing Hydroclimate Whiplash” bit.ly/SwainNAS

Confused or curious about the Bill Gates climate memo? I've got you covered! TOMORROW at 1:30pm PT, I'm talking with 4 great scientists.

Great piece about why Zone Zero rulemaking is complicated for a state as big and diverse as CA. Thanks @nohaggerty.bsky.social for the clarity, and to the many (mostly) SoCal voices of reason including Max Moritz @ucanr.edu for improving the outcomes. www.latimes.com/environment/...

The state’s current consultation policies, while stronger than in many other states, remain inadequate and are inconsistently applied, leading to significant risks of irreparable harm to Tribal cultural heritage sites. #cawater mavensnotebook.com/2025/10/31/u...

The USDA sent an email to grocery stores telling them they are prohibited from offering special discounts to customers affected by the SNAP funding lapse. I'm aware of at least 2 stores that had offered struggling customers a discount, then withdrew it after receiving this email

Quite warm and dry weather will continue across CA this weekend, but next week is looking a bit different than originally predicted. Subtropical ridging will indeed persist, keeping SoCal mostly or completely dry for foreseeable future--but NorCal looks notably wetter. [1/3] #CAwx

“We have not yet seen enough rain in Southern California to end fire season,” said Daniel Swain, @weatherwest.bsky.social climate scientist with @ucanr.edu tells @paulrogerssjm.bsky.social. “But we probably have in Northern California.”

“The problem is that climate change is not divorced from poverty, or health inequity, or food insecurity, or any of these things,” Daniel Swain @weatherwest.bsky.social @ucanr.edu told @gizmodo.com. Climate change profoundly exacerbates these humanitarian threats gizmodo.com/bill-gates-c...

His outfit wasn't as scandalous as Teyana's, but Daniel Swain @weatherwest.bsky.social @ucanr.edu walked the TIME100 Next red carpet with the other stars for last night's gala 🌟 www.upi.com/News_Photos/...

If you are in Davis and will be affected by the SNAP benefits cut, go to Central Park at 9 pm on weekdays for the Night Market. It’s run by good people, I’ve checked it out and gotten a couple of things from it myself, and there was plenty of food - they collect surplus food from nearby restaurants.

"Livestock producers and wildlife managers around the West have been experimenting with strategies to minimize the need to remove predators," write @natureatcal.bsky.social & @ucanr.edu scientists. Ranchers try “range riding,” flashing lights or loud music to deter wolves from attacking calves

I wanted to offer some thoughts on the Gates climate memo that has been circulating this week. While I can't directly speak for others, I can say that my own response is one of dismay & deep frustration (and that this view is shared by many climate/Earth scientists). [1/n]

Drought could deny us pistachios, which are a key ingredient of Dubai chocolate. If growers irrigate pistachio trees under limited water conditions, “Yield will decline,” orchard advisor Phoebe Gordon @ucanr.edu tells Carlos Lomeli-Cabrera @kqednews.kqed.org www.kqed.org/news/1206070...

“Nutsedge competes for water, nutrients and can block out sunlight if it’s not removed before it spreads out in cilantro,” Oleg Daugovish @ucanr.edu said. “The only way to get rid of nutsedge currently is to pull it out by hand, which is cost-prohibitive in cilantro.” www.agalert.com/california-a...

“Maybe the most important thing to understand about hurricanes in the warming world is that not all of them will be able to take advantage of the raised ceiling from ocean warming... this one did,” Daniel Swain @weatherwest.bsky.social at @ucanr.edu, told @afreedma.bsky.social #HurricaneMelissa
