Trump demands that the UK allows American chlorinated chicken and hormone-treated meat into its supermarkets.
UK already agreed to pay more for US drugs, reduced tax on private equity managers, considering cutting tax on tech companies.

The importance of NCAR and the damage wrought by Trump administration actions is very well summarised by Ben Santer in this article @ueaenv.bsky.social @climateuea.bsky.social
"Attempting to erase a country’s scientific heritage, as the Trump administration is now trying to do, should be of concern to every US citizen. Because if climate science is viewed with disfavor today, other fields of scientific inquiry might be next in line for the chopping block."—Ben Santer.
Threatening NCAR, Trump administration seeks to extinguish a beacon of climate science
The Trump administration’s world view is that the US doesn’t need a climate science brain trust because it doesn’t like what the brains say.

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.
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.
