President Donald Trump is reportedly poised to pull the U.S. out of the Paris climate agreement, and Neil deGrasse Tyson is clearly not happy.
In just one blistering tweet Wednesday, the astrophysicist threw major shade on the Trump administration’s controversial climate change policies — and suggested why it was considering withdrawing from the landmark deal in the first place.
The post has since gone viral, with many of his followers appearing to agree with his sentiment:
Trump plans to announce his decision on the Paris Accord via a press conference from the White House Rose Garden at 3 p.m. ET on Thursday.
