I am the Federal Clean Air Director and a senior attorney for the Natural Resources Defense Council. This is my personal account.

In the hot, hazy, smoggy summer of 1988, George H. W. Bush declared it “the year the Earth spoke back” and pledged to use the White House effect to fight the greenhouse effect. The Earth is screaming again this summer, but Donald Trump is using the White House effect to make it *worse*.

Good news! A major U.S. federal court just rejected the EPA’s attempt to roll back Biden-era limits on deadly soot pollution. This is a vital win in the midst of the Trump administration’s relentless attacks on clean air.

BREAKING: In our case, blocking the slush fund, the Trump admin has refused to say under oath the fund is not moving forward, even after the court gave them a week to do this. We aren’t surprised. We already blocked this fund and will aggressively pursue the next steps in the case.

No joke, it would be cheaper to pay every coal miner $5m every year to not mine coal. There are only 40,000 coal miners, while the coal industry produces >$500 billion in external costs every year, including by routinely burning coal just to burn it despite it costing more ("uneconomic dispatch").

"This first phase of the Monarch Compute Campus will be a 2.16-gigawatt natural gas-fired off-grid facility. It will rely on 864 reciprocating internal combustion engines and associated equipment. Another 120 engines six burning natural gas and the others using diesel fuel for other uses."

Thread. The Trump administration’s air-pollution-truther garbage is hostile to human life on a scale not unlike its willful destruction of USAID and its efforts to undermine vaccinations

Each part of this Trump EPA statement about deadly soot pollution is a lie or reckless or both. ctmirror.org/2026/04/21/t... The harmful impacts PM2.5 & ozone emissions have on human health are among the best established realities in human health science. Trump's EPA is "still considering" them. 1/
