Where did the 97% agreement on Climate Change Crisis come from?

Where did the 97% agreement on Climate Change Crisis come from?

The claim that 97% of the world’s scientists agree is pretty much the ace of trumps in the whole climate debate. After all, who’s going to argue against a consensus that strong, backed by so many experts. But what exactly are they supposed to agree on? If you look behind the curtain, no one seems sure what the experts actually said.

At first glance it seems straightforward enough. In 2013 President Barack Obama famously tweeted that “Ninety-seven percent of scientists agree: #climate change is real, manmade and dangerous.”

In 2014, his Secretary of State John Kerry said 97% of “the world’s scientists tell us this is urgent.” And that same year, CNN said “97% of scientists agree that climate change is happening now, that it’s damaging the planet and that it’s manmade.”

That’s pretty much what most people think when they hear the 97% slogan: Every scientist believes man-made climate change is an urgent crisis.

But there are millions of scientists in the world. How many exactly were surveyed? When were they surveyed? Who did it? And what exactly did they agree on?

Please take the time to watch this video below, it tackles this question about the 97%.
