Today, the U.S. faces one billion+ dollar climate/weather disaster on average every 2w. That's a massive increase from one every 4m in the 1980s.
This is 'global weirding' and people are taking notice!
The government told NOAA to stop tracking these events: but @climatecentral.org is on the job.

Our comment on the DOE CWG report is done. It tips the scales at 439 pages, approx. 3x longer than the DOE report.
This is related to Brandolini's law: The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it.
Example: refuting one sentence.

We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me.
We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

I was honored to work on the 5th National Climate Assessment in 2022-23. One of my most inspiring moments in climate was sitting in a hotel ballroom with hundreds of experts, scientists, and civil servants, all working to inform Americans about our possible futures. www.nytimes.com/2025/04/28/c...

The Trump administration told researchers it was “releasing” them from their roles. It puts the future of the assessment, which is required by Congress, in doubt.

This is such a horrible loss for NOAA and all of us. I’m so sorry Tom.
Please enjoy my last ever post at Climate.gov/ENSO Blog. This afternoon I was fired by the Trump Administration 15 days before my 2yr probationary period ended on March 13.
I have worked at NOAA since 2010, and I'm so incredibly proud of the work I did. If anyone wants a quote, let me know.

Predicting El Niño and La Niña is tough, but new research analyzing 20+ years of forecasts finds dynamical models outperform statistical ones, especially for El Niño. La Niña onset? That's been much harder. Read more in our new ENSO blog post! www.climate.gov/news-feature...
