There is a 97% scientific expert consensus on human-caused global warming. That consensus isn’t a result of groupthink, or a vast conspiracy, or money-grubbing scientists lying to get their greedy little hands on grant funds. In fact, scientists are very hard to convince of anything, and they’d much rather be the one to disprove a theory than the twenty-thousandth to reaffirm it. 

Scientists base their conclusions on evidence and the evidence for human-caused global warming is overwhelming. Trump and his cabinet don’t consider climate change a threat, because they want you to think the question of human responsibility is still under debate. That's one of the reasons the Trump administration talks about “alternative facts.”

The interesting thing about scientific facts is they're right whether Trump agrees with them or not. They're not subject to his or any other climate deniers opinion. We'll see what alternative facts Trump tries to spin when Mar a Lago is under water.
