And now NCAR. Science, on all fronts, is in tatters. The regression leaves the country and the world much worse off. Recovery from this damage to the United States will take decades.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Before the 1990s, plane crashes caused by microbursts used to kill planeloads of people fairly regularly.
Dr. Ted Fujita and NCAR scientists figured out how to detect microbursts and warn pilots about them.
Since then? Zero airliner crashes from microbursts.

When you ask weather/climate people to name places that act as a hub of lifesaving research and innovation, Boulder CO would rise to top 2-3. NCAR Mesa Lab is the heartbeat of activities there. Can’t believe this is even on the table, let alone being lobbed out there like it’s already a certainty.

NCAR does a whole lot more than just climate research, and I think calling it a climate research lab paints an incomplete picture. Atmospheric chemistry, severe thunderstorms, radar, software and tools, etc.

NCAR is crucial to cutting-edge meteorology and improvements in weather forecasting. As others have noted, it's far, far bigger than a "climate" research lab. This is self-sabotage by a wildly ignorant and malicious administration cutting off their nose to spite their face. Find a better scapegoat.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.

These people are nuts. NCAR developed the GPS dropsonde, which revolutionized the understanding of TC structure, improved forecasts, and validated remote sensing platforms, as documented in over 400 peer-reviewed publications in the last 25 years. And that’s just one of NCAR’s countless advances.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

This is terrifying.
It appears that the U.S. Environmental Protection Agency (EPA) has, within the past week, scrubbed a large amount of climate change content from its official website, as well as *removed human-caused warming* from the discussion on its "causes of climate change" page.

This is absolutely awful. This was one of the best resources for climate indicators data, and my go-to share for help answering public questions.
Luckily I captured some of them on my new U.S. climate page a few months ago: zacklabe.com/united-state...

Additionally, it appears that all of EPA's previously extensive "indicators of climate change" pages have been scrubbed entirely. The pages no longer exist; there are numerous dead links on the current/live EPA site, and no indication they have been moved to a new URL.

Many important weather and climate data streams have gone silent as the U.S. government shutdown continues on.
As just one example, NOAA’s Global Monitoring Laboratory did not release its regular monthly update for greenhouse gases, such as for carbon dioxide, methane, and nitrous oxide.
