There's a lot to look at in last month's map of average sea surface temperature anomalies. The La Niña signature continues to become more prominent. Meanwhile, the absurd record warmth over the North Pacific is still extending all the way from Asia to North America. Data from NOAA OISSTv2.1 🌊

The Northern Pacific Ocean is currently smashing temperature records. And it is reaching these levels far earlier than the current generation of climate models had expected. A short thread 🧵

We believe women. It is not a hoax, it's so commonplace in science that the National Academies have an entire report on it. Release the Epstein files #resist 500womenscientists.org/updates/2025...

How has climate change shaped your lifetime of heat? Younger people today are experiencing more extremely hot days during their childhood compared to previous generations. Check out the new interactive tool by @climatecentral.org: climatecentral.observablehq.cloud/generational...

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

Our 400+ page comment on the DOE climate working group report is now out. Our conclusion: The merchants of doubt are back, and they're coming for climate science.

Just so we're all clear, I've added Judith Curry's 2014 "hiatus" (no additional warming) prediction on this graph showing what's actually happened since:

A long-major heatwave is setting up for Central & NW Canada with temperatures 15-20 degrees C (30F plus) warmer than normal late next week into next weekend. That means widespread 30-35C high temps (85-95F) way up north even near the Tundra. Climate change has made these events more intense/ likely

Climate models have underestimated the departure of high temperature extremes from monthly means. If we assume these model biases persist in future projections, then the climate models are also likely underestimating the magnitude of future high temperature extremes. www.nature.com/articles/s43...

The ruling from the International Court of Justice last week is genuinely a big fucking deal. It makes it a legal obligation for countries to address climate change. Yes, even the ones not signed on to Paris. Yes, even the U.S. More from me & @rishpardikar.bsky.social drilled.media/news/ijc-1

This is a pretty alarming new study out today (doi.org/10.1126/scia... - read the abstract) and here are some great visuals and highlights from it by @propublica.org: www.propublica.org/article/wate... "Since 2002, 75% of the population lives in 101 countries that have been losing freshwater water"

Yeah this is the thing I'm told me and all my students need to uncritically embrace so they can get a job after college

This is a great article by Bill McKibben @billmckibben.bsky.social on how solar power hit an inflection point and has now become an unstoppable force. A must read. www.newyorker.com/news/annals-...

Under Trump, NOAA ran the most recent competition for their highly prestigious postdoc program in climate and global change — but funded no one, wasting huge amounts of applicant and reviewer time. It gets a lot worse. Now current postdocs in the program are going unpaid.

I can't stress enough how close U.S. science is to the cliff. "Numbers released in May by the National Science Foundation (NSF) indicate that if Congress approves the cuts to the agency proposed by the White House, the number of early-career researchers it supports could fall by 78%" (@science.org)

this is an excellent discussion of the July 4th Hill Country floods by @travisabc13.bsky.social, ABC13's chief meteorologist and a graduate of our program, @tamuatmo.bsky.social.

Are you from one of these states? Then we need your help to save American science! The Senate Appropriations Committee will be marking up the President's Budget Request for science on Wednesday. People have been saying the proposed cuts "decimated" US science, but that's wrong: they are apocalyptic

Disappearing snowpack across cold forests of the north could substantially slow their growth, in what researchers say is an overlooked consequence of climate change. 🧪🌍

The White House took down a website hosting the nation's top report on how climate change is affecting the United States.

The proposed NOAA budget for 2026 contains the literal line: Total, Climate Research: $0 www.commerce.gov/sites/defaul...

Proposed NOAA budget zeros out ALL climate laboratories and cooperative institutions. GFDL, NSSL, GML, etc. This appears to also end the US greenhouse gas sampling network, including at Mauna Loa, the oldest continuous carbon dioxide monitoring site on Earth. www.commerce.gov/sites/defaul...

ESRI has the interactive NCA atlas here:

Here is the web archive version of NCA5: web.archive.org/web/20250626...

Among the many resources the Global Change Research Program hosted was this interactive atlas of projected changes in relevant thresholds (e.g. hot & cold days, rainfall amounts and more) per degree of warming, showing people how meeting the Paris targets would impact them personally.

This is theft, plain and simple. They stole this from you. Every deletion, every erasure, every website that goes dark is a crime against the American public

The US Global Change Research Program's website, including all its sub-domains that host the National Climate Assessments and related reports, is now offline. The 1990 Global Change Research Act (see below) mandates its research findings be available to all federal agencies & departments.

A huge blow was dealt to hurricane forecasters this week as a critical tool was abruptly terminated by the Department of Defense and NOAA. The immediate discontinuation of data from three weather satellites will severely impact hurricane forecasts this season and beyond. More ⬇️

Today, Joe Rogan said: “Did you see the WaPo piece? They found that we’re in a cooling period…a very ‘inconvenient’ discovery, but they had to report the data—and kudos to them for doing that.” I'd love to know how WaPo found that cooling period and, even more importantly, where they hid it.

Y'all, this past week for science funding lawsuits has been 🔥🔥🔥 ✅ Major recent wins regarding: 1. U of California researchers 2. NSF indirects 3. NIH terminations 4. EPA terminations Plus: 5. Brand new NSF lawsuit (about terminations & slowdown of new awards) 🧵 Let's break it down

My challenge to you is to talk about it (more). Talk about climate change. Talk about the importance of the scientific infrastructure in the US. Talk about the implications of these cuts on the economy, our health, public safety, the environment, and what this means for the next generation as well.

They are kicking the National Science Foundation out of their 8-year-old HQ building, with no alternative plan for housing staff, in order to make a gym for Secretary of Housing & Urban Development Scott Turner and his family.

"Extreme summer weather patterns have tripled since the 1950s" | Great piece in @upenn.edu's #PennToday on our recent @pnas.org article, providing critical context for the extreme heat we're seeing right now in North America and Europe: penntoday.upenn.edu/news/extreme...

Today's Climate Shift Index (CSI) is highlighting just how much climate change has made today's heat wave more likely to occur, especially for the warm nighttime temperatures. Follow along with real-time and forecast CSI global maps from @climatecentral.org at csi.climatecentral.org/climate-shif...

Yikes! “Stuck” summer jet stream patterns responsible for many crazy extremes seen in recent years have increased 3x in 70 years, something “not well captured by current-generation climate models…indicating even greater risk of persistent extreme summer weather events with ongoing warming.”

Trump administration cuts to NSF will result in more than 200,000 FEWER people per year involved in basic science, training, and education - what should have been the next generation of US scientists. This isn't even eating your seed corn, it is setting your seed corn on fire and salting the earth.

Would it have killed them to mention the fact that this was due to climate change? @powcanada.bsky.social
