Fact check, please: EPA chief @GinaEPA says '99% of scientists agree climate change is happening'

Last week the White House organized #BigBlockOfCheese day to let Americans interact directly with some of the top people in the Obama administration via social media.

Here’s one of the questions to EPA chief Gina McCarthy:

Why are there such drastically different opinions on climate change? @GinaEPA #BigBlockOfCheeseDay

And here’s her answer which it looks like she just made up:

There aren't. 99% of scientists agree climate change is happening. #BigBlockOfCheeseDay https://t.co/GCQKfU7JoM

Oh, really? “There aren’t” any different opinions? 99% of all scientists agree that “climate change is happening”? How about a link to that study, eh?

Please reference the evidence of this claim. https://t.co/DlAqZbnvI3

Less than 1% of scientists are climate scientists.
Under half of climate scientists say man causes global warming. https://t.co/PPY08OZK0V

We assume she bungled the often used “97% of climate scientists agree” that climate change is happening and humans are the main cause of it, but that’s wrong, too:

@GinaEPA @CoachJsClass According to 2014 WSJ article there is no basis for Ms. McCarthy's claim. https://t.co/soYQNWdwfw

@GinaEPA May be climate change (see Greenland) but the "99%" is misleading as less than 40% say man made- https://t.co/f94e1O2KDV Fact, no?

So why just make stuff up? Here’s one answer:

@GinaEPA this government believes it can defeat opposing views by claiming there are none..
