The Trump administration is reviewing proposals to break up one of the world’s leading climate and weather laboratories, transfer its work to universities and private companies, take away its aircraft, and sell its property in Boulder, Colo.

The laboratory, the National Center for Atmospheric Research, has been targeted for months by the Trump administration. In a social media post in December, Russell Vought, the White House budget director, called the Colorado center “one of the largest sources of climate alarmism in the country.”
