Watch Neil deGrasse Tyson Debunk Climate Change Denier Claims in Two Minutes

The ‘Cosmos’ host explains why a cold winter doesn’t make global warming a hoax.

Despite 97 percent of climate scientists saying otherwise, there’s a clamorous crowd arguing that global warming isn’t a problem. Sen. Marco Rubio doesn’t think human activity affects the climate “the way these scientists are portraying it.” Even Pat Sajak—who later claimed that he was joking—disparaged climate change activists two weeks ago on Twitter. In comes astrophysicist and Cosmos host Neil deGrasse Tyson, who appears to have had enough of the antiscience talk.

In this clip from tonight’s episode, Tyson starts by echoing the skepticism of global warming deniers: “OK, so if we scientists are so good at making these dire, long-term predictions about the climate, how come we’re so lousy about predicting the weather? Besides, this year we had a colder winter in my town. For all the scientists know, we could be in for global cooling.”

He then spells out the difference between weather and climate, using the simple analogy of walking a dog on the beach.

“The average weather over the course of years reveals a pattern. I represent that long-term trend, which is climate,” Tyson explains. “Keep your eye on the man, not the dog.”

The entire episode will be dedicated to climate and will address society’s perception of global warming. Who knows? Maybe the charming host can convert a few nonbelievers. Either way, the show could serve as a good primer for the issue the U.S. government has pledged to tackle aggressively starting Monday, when the Environmental Protection Agency will take the most significant step it has ever taken to battle global warming: capping greenhouse gas emissions from power plants, the country’s biggest climate change culprit.
