Trump mocks global warming in tweet

President Trump mocked the idea of global warming in a tweet Thursday, making one of his first (if not the first) such public comments on the topic since entering the White House almost a year ago.

Why it matters: Trump has tweeted in the past that he thinks global warming is a hoax, but that was in 2012 and he has not focused on the topic much at all in his Twitter activity as president. This tweet shows he's still openly mocking mainstream climate change science, even without directly questioning it.
