For the first time since becoming President, Donald Trump has paraded his climate change denial on Twitter.

Trump posted his defiance of science in a message from his Florida vacation to those facing freezing temperatures along the East Coast:

Steadily increasing temperatures with climate change led to 2016 as the hottest year in history, and some studies show 2017 is on pace to become the fourth consecutive year to claim the record.

But the Trump White House has been dedicated in pushing aside any recognition. It has barred references to “climate change” on websites and in Government memoranda, sharply cut funding for scientific evaluation, gutted regulations, and withdrawn from the Paris Accord, leaving the US as the only country in the world outside the agreement. Climate change deniers have been appointed to senior positions, and Scott Pruitt, the head of the Environmental Protection Agency, has said that he does not believe the science about human-based climate change.

Trump’s Thursday tweet revived his forthright denial of any climate issue. In 2012, he chided:

A year later, he returned to his observations of the weather:

By the 2016 campaign, he refined his argument of a Chinese hoax:

Well, I think the climate change is just a very, very expensive form of tax. A lot of people are making a lot of money. I know much about climate change. I’d be — received environmental awards.

And I often joke that this is done for the benefit of China. Obviously, I joke. But this is done for the benefit of China, because China does not do anything to help climate change.

A White House official did not respond when asked what Trump’s latest tweet means for Administration policy.
