I’ve spent more than a year reporting on how the fossil fuel industry has infiltrated academia over the last 30 years, shaping fundamental paradigms on how to address climate change. My first story in the new @propublica.org and @drilledmedia.bsky.social series, “Carbon Captured”, is out today.

The UK summer of 1976 was an extraordinary heatwave for its time. On the 50th anniversary, we look back to learn about what that event can tell us today. For those who experienced the heatwave it is engrained in the memory, but it gives us a stark warning about future extreme heat for the UK.

As Hudson Bay sea ice melts, the bears are moving onshore. This is a bit early than optimal but depends on the condition of the bears & how long until freeze-up in autumn. Bears were lean in April-May when I was out sampling in the spring but a lot can change later in spring (most critical time).

What is the probability (and physical mechanisms) of having your local record temperature occur earlier or later than the climatologically hottest time of year? E.g., the 2021 PNW heatwave occurred >1 month before the hottest time of year. Anyone know a study? Figure based on ERA5 1940-2025.

El Niño is here, which means it's time for me to dust off and refine my old collection of ENSO-related climate visualizations. Check out how much sea surface temperatures have already warmed this year across the equatorial tropical Pacific. Wow! Data from psl.noaa.gov/data/gridded...

NY times covered our cut today (gift article) www.nytimes.com/2026/06/12/s...

Context: in 2018, FB labeled clean energy & climate as “political” topics. I was told I had to “register as a political entity.” I’m a scientist, I said. Over my dead body. So my previously thriving page was shadowbanned-til Dec when the algo was altered to deliberately promote divisive content 😳

May 2026 had the second-worst May drought conditions in contiguous U.S. history, with a Palmer Drought Severity Index (PDSI) of -6.93. The only worse May: the Dust Bowl year of 1934 (a PDSI of -7.03). Three of the top-10 months for worst U.S. drought since 1895 have been in 2026:

Ein problem für ganz Europa, und wo die USA ausnahmsweise auch voraus liegt (durch ua die flächendeckende Klimaanlagenaustattung ist die Anzahl der Hitzetote generell viel niedriger, auch bei ähnlichen und teils viel schlimmeren Hitzeperioden!) (zB hannahritchie.substack.com/p/heat-guns-... )

Thank you for joining us and speaking out in support of weather & climate science, @repericsorensen.bsky.social ! @wclivestream.bsky.social

That's a wrap! - 50 hours of science + calling Congress - 300 letters given to Congress after a 250-mile walk We provided the templates and our viewers and supporters injected their voices. And like last year, we feel so uplifted by our community. Thank you for spending your time with us

Thanks Jeff! Emphasis on "may". Lots of competing (and complementary) theories out there on which forcing will win out. I did make a bet with another professor re snow drought occurrence this decade. The looser will have to give a guest lecture explaining why they lost. :)

I’m a climate scientist. Let me fix this headline. “Nearly a century ago, scientists showed that burning fossil fuels warms the planet. Today, we know human emissions account for over 100% of the warming. Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”

@wclivestream.bsky.social 's very own Syl Foisy is walking 250 miles from NYC -> DC ! Follow along on our Bluesky, YouTube & Instagram (all at @wclivestream)! The walk culminates in a 50 hour-long Livestream starting June 1st! GET HYPED! 😁

The 250-mile @wclivestream.bsky.social walk to deliver letters in support of science directly to Congress doesn't begin until 10am, but I am officially claiming the first miles traveled on behalf of the walking team 🏆 (the others live in NYC but I have to get there!)

If you're a reviewer or an editor for a scientific journal, I urge you to not hop on the "RCP8.5 is dead" train. There are now editors that reject RCP8.5 but are ok with 1pctCO2. 🤯 Both are what-if scenarios, useful to science. Don't let politics influence what we can research and publish! 1/3

🚨 The Weather and Climate Livestream is back, June 1st - 3rd 2026!! We're streaming 50 hours for our future in the face of a new round of proposed budget cuts and attacks on science. Want to speak at the event? wclivestream.com/volunteer/

We have a new preprint on this, led by my former postdoc David Lafferty (now at Verisk) and with a great set of co-authors including @climateflavors.bsky.social. We use a "meta-ensemble" of downscaled climate products to partition temperature and precipitation projection uncertainty across CONUS.

🧵 There's been a lot of noise about the 'dropping' of RCP8.5 and what that means for worst-case climate outcomes. But this debate is largely missing the point. 1/6 #ClimateScience #ClimateRisk #Adaptation #ClimateModels

Very interesting paper teasing out the nuances of flood risk distribution in the US using an incredible individual-level dataset. Documents a huge concentration of flood risk among the very highest income group - lots of wealthy people enjoying the coast and river views from their second homes.

Hi everyone, gridded data for the flat10MIP project is now open and public on the Norwegian Research Data Archive. Research using these data for understanding carbon-climate feedbacks, including climate commitment and reversibility is super relevant for AR7-WG1. archive.sigma2.no/dataset/flat...

In the SPM of IPCC AR6 WGI there was a hexagon gap in assessed trends of heatwaves & extreme rainfall in Central Africa Can the hexagon gap be filled for AR7? @derrickmuheki.bsky.social et al. have rescued millions of historical observations from the Congo: egusphere.copernicus.org/preprints/20...

Wondering how to motivate students in intro programming classes? "... writing skill and CS achievement are significant predictors of vibe-coding performance, and CS achievement remains a significant predictor after controlling for domain-general cognitive skills." dl.acm.org/doi/10.1145/...

I regret to inform you that they are once again allowing me to share my opinion in public tasteofscience.org/new-york-eve...

After a year of repairs, one of the world's most beautiful commutes - the Cascadilla Gorge trail to Cornell - is open again!

"Climate science is not innately politically charged, whatever the administration says. ... It was our job to study the laws of physics, which remain true no matter who’s in power." - Kate Marvel, Sr. Scientist, Project Drawdown 📰 Full article in the @newyorktimes: https://nyti.ms/4tBNtEf

So... now we can breathe again. Let's talk about ScenarioMIP. The final version is now up on GMD - and there's some changes since the first draft. /THREAD/ gmd.copernicus.org/articles/19/...

This excellent piece from @madisoncondon.bsky.social shows why (nerd alert!)—even if the scenario underlying RCP 8.5 is implausible, RCP 8.5 serves an important role in our understanding of and planning for climate change, and is therefore not misleading. progressivereform.org/publications...

Indeed, wild to be in CO at this moment in time talking about our new 3km snowpack simulations. Great visit to a great department! Lots of fresh ideas on what drives Southwest drying. Thanks Maria Rugenstein and CSU!

My resignation letter

Just in: UCAR has filed a lawsuit against NSF, the Commerce Dept, NOAA, and OMB to prevent the dismantling of NCAR, alleging "violations of the Constitution and the Administrative Procedure Act."

This should be the biggest weather and climate news on your radar today. You can send an email today to say why dismantling NCAR is a bad idea for everyone: [email protected]

Today we showed up. Feeling proud of scientists and science supporters in this moment. Thank you all. #Standupforscience

This is going to be useful: The CMIP Rapid Evaluation Framework (REF) for derived data from the CMIP archives: dashboard.climate-ref.org Still working out the kinks and focused on CMIP6, but will expand for CMIP7. #CMIP2026

One year in the federal assault on climate science — a review and prospective

Hudson Bay polar bears took a big jump to the northwest this week. Why? I'm guessing favourable winds that made hunting that direction more effective (but we don't know for sure & it's something we're investigating).

Need more industries to speak up against the attacks on NCAR. www.riskmarketnews.com/trumps-clima...

Hudson Bay are well spread out & doing different things. One female (K) has moved close to shore. Bear C has emerged from a den - it's a bit early if she's got new cubs but we'll see if she stays there or moves onto the ice.

docs.google.com/document/d/1... Hey folks, tried putting together a letter in direct response to the NSF unprompted decision. Feel free to offer suggestion or to add your name as a signatory, and thanks to those that did it alredy! Current text follows (errors all mine!)...

Last December, weather and climate scientists sat down with us to tell us why they loved the National Center for Atmospheric Research, and why it benefits us all. Last night, the NSF began dismantling it. Listen to what they have to say, and why it's urgent that we #SaveNCAR wclivestream.com/act

🧵How might snowfall change in a warming world? I set up a very simple “toy” statistical model to explore this question. Isn't it obvious that snowfall decreases as temperatures get warmer? Yes, but …

I honestly thought December was way colder in the Northeast than what the numbers indicate. Seven mild Decembers in a row really messes up your perception...
