What Americans Lose If Their National Center for Atmospheric Research Is Dismantled - Eos Five ways dismantling NCAR will cost the American people, and two ways to save it.

NCAR represents what is possible when a nation chooses to invest in science as a public good, writes @carlonimbus.bsky.social of @ucs.org. #SaveNCAR

Attention folks in the weather, climate, disaster, wildfire, and Earth science communities: NSF has just published a new "Dear Colleague" letter inviting feedback (by Mar 13) on the proposal to dismantle the National Center for Atmospheric Research (NCAR). www.nsf.gov/funding/...

As severe convective storms become a dominant driver of insured losses, it is important to accurately estimate risk from SCS hazards, and that this is done beyond only using historical events. Here is a framework using an ensemble forecast system. Dataset available on Zenodo: doi.org/10.5281/zeno...

A Global Ensemble Forecast System (GEFS)-based synthetic event set of U.S. tornado outbreaks Abstract. Severe convective storms (SCS) are important drivers of global insured losses, and tornado outbreaks – when many tornadoes occur within a short time span – cause extreme and localized loss o...

🌪️ Happy to share this new paper from @mktippett.bsky.social and I. We constructed a synthetic event set for U.S. tornado outbreaks. It has 200,000+++ events, which can be boiled down to resolve localized risk, and we detect robust shifts in activity due to ENSO and trends.

Looking forward to participating in this webinar! Happening this Thurs!

An atmospheric general circulation model you can run on a Python Jupyter notebook?! Heck yeah! Check out this project- both an educational tool for undergraduates/graduate students, and a research tool for scientists interested in idealized climate modeling.

CNN news story, Climate.gov will re-launch under new URL thanks to a secret team of web ninjas

Curious what we are all about?

Congrats, Suzana!! Well deserved!

Sad to see that leadership didn’t approve of my suggested post language (assuming since this is what is posted) that I submitted on my last day in May as the social media manager.

Allow me share some of our team’s kind words here instead:

Our final updates have been posted to the Climate.gov website, and this will be our final post to our social media channels.

Table showing FY26 budget numbers for NOAA from the Trump Administration.

Trump's Budget is out. For NOAA, it's exactly what the previous passback document showed.

Bonus plot for Bluesky folks: Seems like AO is part of the story for this season. The teal dot is Mar 2025 (w/ prelim SPC report data), modestly AO+, which can be a subseasonal signal for increased tornado activity, i.e., top-left quadrant La Niña/AO+ does feature a lot of big tornado months...

How do a climate-scale patterns, like La Niña, influence extreme weather events, like tornado outbreaks? I break it down in this ENSO Blog post, plus discuss this hyperactive 2025 season in particular. 🌪️

Federal weather & climate science is under threat. Starting TODAY at 3:00 PM ET, join a coalition of scientists--including AMS leaders--for a 100-hour livestream. Learn what federal science does for you, ask questions, and help build awareness to "Save Our Forecasts": wclivestream.com

A major loss to our understanding of how extreme weather events are affecting us. There are 3 alternative databases I will be using:

I usually include NOAA NCEI billion-dollar weather/climate disaster figures in my talks. Over the last couple months, I've spent extra time highlighting who makes them and why it's so valuable, including "while we still have this data..." to convey my worry. Sadly I guess my fears were warranted.

Just kidding, I guess bluesky doesn't allow animated gifs yet? Guess you'll have to click on link to see!

How QBO affects weather/climate patterns can be confusing, but @jorgelgf.bsky.social tries to break down the main QBO teleconnection routes in this post. As usual, we had fun with graphics... here's an animated schematic:

The canceled grands are shock and awe, but the real damage will come from the long-term (massive) reductions in funding to the entire US research ecosystem and the defunding of entire fields and initiatives for training, growing, and diversifying the research workforce.

The gap between where people live and where insurance remains available is widening across the U.S. We explore this in our recent paper, “The Growing Void in the U.S. Homeowners Insurance Market: Who Should Bear the Rising Cost of Climate Change” co-authored with Ian Gray @stevebowen.bsky.social

Trump seeks to end climate research at premier U.S. climate agency White House aims to end NOAA’s research office; NASA also targeted

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency.

Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

Ending Cooperative Agreements’ Funding to Princeton University On Tuesday, April 8, 2025, U.S. Secretary of Commerce Howard Lutnick announced that nearly $4 million in funding is ending to Princeton University after a detailed, careful, and thorough review of the...

Get this: Commerce is slashing $ to Princeton's world-renowned climate research b/c modeling changes to Earth systems is "contributing to a phenomenon known as 'climate anxiety,' which has increased significantly among America’s youth."
