There is lots of chatter about the forecast development of a strong #ElNiño. Models are in very good agreement on that. But the consensus is an "average" strong El Niño, not historic. RONI values: bmcnoldy.earth.miami.edu/tropics/roni/ ENSO forecasts: iri.columbia.edu/our-expertis... [1/3]

Tax the oil companies and invest in climate mitigation/adaptation infrastructure now!

I wonder which party cares more about the working class

What exactly is El Niño, and what makes this year’s event “super”? What happens when El Niño interacts with fossil fuel–driven climate change? UCS’s @marc-alessi.bsky.social breaks it all down in his new blog:

I am simultaneously so excited to be living during an energy revolution while terrified and disgusted by everything the fossil fuel industry is doing to stop it

This #EarthDay, we’re grateful to NASA and the Artemis II crew for giving us a whole new perspective on our work tackling the world’s most pressing issues.

Republicans, bought out by fossil fuel companies, are doing their very best to shield ff companies from any accountability from climate change damages. It’s just insane levels of corruption. Never forget that Shell predicted this over 25 years ago: www.ucs.org/resources/fo...

The swath of over 1 foot of rain needed for drought recovery in the South…

How could the CA marine heatwave impact Southwest US precipitation? During my PhD, I used a Green's function to analyze Southwest US precipitation sensitivity to patterns of ocean surface temperature. Here's a map showing that sensitivity...

Big Oil companies are going all-out to avoid taking responsibility for the harm caused to communities and for driving the climate crisis. They are using an age-old strategy: delay, distort, and deny. But we won’t let them off the hook.

This global surface temperature forecast from UMiami is striking: there is a nonzero chance that we'll experience a monthly global temperature anomaly of +2.0C if a super El Niño develops later this year.

This is wild! “Even more troublingly, other researchers say, the fake papers were then cited in peer-reviewed literature. Osmanovic Thunström says this suggests that some researchers are relying on AI-generated references without reading the underlying papers.”

I love a day out in upstate NY

woah cold front!!

For more information on what the AMOC is, what’s causing its collapse, and what could happen to the Earth’s weather patterns if it does collapse, check out @marc-alessi.bsky.social blog on the AMOC circulation:

New science is out on one of Earth's critical "tipping points": the potential collapse of the Atlantic Meridional Overturning Circulation (AMOC), which brings warm Gulf Stream water toward Europe and helps make the mild climate of northern Europe possible. (🧵⬇️)

For humans’ ~300k year history, we have existed in a climate where carbon dioxide (CO2) concentrations in the atmosphere were between 180 and 280ppm. 1200ppm of CO2 in the atmosphere would be devastating for not only the Earth’s climate system, but for human civilization.

According to the Climate Prediction Center, there's about a 40% chance of a "strong" or "very strong" El Nino at the end of this year...

A story in three parts

As the first reanalysis data become available, I think I can say with a fairly high degree of confidence that the March 2026 heatwave will go down as the most anomalously extreme heat event ever observed at any time of year in the southwestern U.S.

Flagstaff, Arizona: • March 19, 2026 high: 84°F • Previous March all-time high: 73°F • April all-time high: 80°F That's just plain ridiculous.

According to preliminary/unofficial data from coolwx.com, March 19-22 hold spots 1-4 in days with most high temperature records broken (globally) since 2010.

"A summer-like heat wave… in March? 🌡️📈 As we watch record-shattering temperatures hit the Western US for this time of year, UCS's @marc-alessi.bsky.social explains the direct relationship between these extreme heat events and fossil-fueled climate change."

I found this particularly striking: yesterday broke the *global* high temperature record count. So despite this event only occurring in the western US, it still was record-breaking global for total number of records. This database only goes back to 2010, though.

This was only Day 1... The fact that this heat will continue (and in some places get worst) through the weekend is insane.

39F at my mom’s house in Cicero and 57F at my apartment in downtown Syracuse! Only 9 miles apart!

@ucs.org (I and @marc-alessi.bsky.social on behalf of UCS) have submitted our public comment to the National Science Foundation about its intent to restructure the National Center for Atmospheric Research (NCAR) @ncar-ucar.bsky.social We are very concerned (no pun intended) by this intent.

Check out our thoughts on this new study on sea level observations in @nature.com!

smashing the old record before the storm is even over is wild!

This band over eastern New England is quite impressive. And the number of locations observing blizzard conditions-- what a storm!

I am so sick of living in a country without a functioning opposition party

⌛Did you vote? There are still 24 hours left! We’re glad to be participating in @projectforawesome.com! Thanks @zentouro.info for the wonderful video featuring UCS's cliamte scientists Angel Fernandez-Bou and @marc-alessi.bsky.social ❤️

@zentouro.info is so awesome for this. Check out this video and vote for @ucs.org in this year's @projectforawesome.com!

8F, no one driving, eyelashes frozen 🫡❄️

Honestly cannot remember the last time we got a synoptic winter storm with temperatures this cold. Heavy snow continuing through the evening...

I mean, tech leaders were quite literally with Trump yesterday:

Nearly 150 million Americans are under a winter storm warning. Some locations might see an inch of ice, which would be devastating. Meanwhile, the government is trying to downplay messaging to avoid reminding folks of the ICE occupation in MN. All at the expense of Americans' safety.

I want to appreciate for a moment: There’s a historic ice storm bearing down on a huge part of the country. And government workers are being told to downplay the ice—the most damaging part of the storm—bc they’re worried it might remind people of the government’s disastrous occupation in Minnesota

The National Science Foundation has just released its Dear Colleague Letter (DCL) regarding NCAR and it is gut-wrenching. The deadline to submit comments to the DCL is March 13th. I urge folks to please share and inform NSF on the critical importance of NCAR. www.nsf.gov/funding/info...

Good luck to those traveling to AMS this weekend...

That heinous DOE climate report written by climate skeptics? Unlawfully formed. Let's take the wins where we can! 👏

I'm not sure how to react to posts like this, because on the one hand, she was perfectly ok with the government going after LGBT families. But on the other hand, this type of messaging is just a tool of the billionaires to turn minorities against each other. We can't organize if we're fighting

We’re following a likely significant winter storm this weekend across a large swath of the United States. The National Weather Service is forecasting heavy snow and freezing rain for many locations that don’t typically see this type of dangerous weather. Check out the latest #NWS graphic:

as trump keeps beating up on renewables, a new analysis shows that we can basically offset data center emissions simply by boosting wind and solar a little bit more:

This Facebook comment I just saw 😢
