New Video: Neil deGrasse Tyson Destroys Climate Deniers

The next episode of “Cosmos” will make the anti-science crowd’s heads explode. Here’s a preview.


For 11 episodes now, the groundbreaking Fox and National Geographic Channel series Cosmos has been exploring the universe, outraging creationists, and giving science teachers across the nation something to show in class every Monday. In the process, the show has been drawing more than 3 million viewers every Sunday night, a respectable number for a science-focused show that is, after all, a major departure from what prime-time audiences are used to.

Cosmos certainly hasn’t shied from controversy; it has taken on evolution and industry-funded science denial, and it has been devoting an increasing amount of attention to the subject of climate change. And apparently that was just the beginning. This coming Sunday, Cosmos will devote an entire episode to the topic. Here’s the episode description from National Geographic:

Our journey begins with a trip to another world and time, an idyllic beach during the last perfect day on the planet Venus, right before a runaway greenhouse effect wreaks havoc on the planet, boiling the oceans and turning the skies a sickening yellow. We then trace the surprisingly lengthy history of our awareness of global warming and alternative energy sources, taking the Ship of the Imagination to intervene at some critical points in time.

Courtesy of National Geographic, above is a clip from the new episode, which should have climate deniers fulminating. In it, host Neil deGrasse Tyson uses the analogy of walking a dog on the beach to helpfully explain the difference between climate and weather (pay attention, Donald Trump) and to outline why, no matter how cold you were in January, that’s no argument against global warming.

We’ve seen the rest of the episode already, and won’t spill the beans. But suffice it to say that it contains some powerful refutations of a number of other global warming denier talking points, as well as some ingenious sequences that explain the planetary-scale significance of climate change. It also contains some in situ reporting on the impacts of climate change, straight from the imperiled Arctic.

Back in November, I observed that if Carl Sagan, the creator and host of the original Cosmos series, were alive today, he would have been a leader in the charge to address global warming. After all, Sagan, who made his scientific mark studying the greenhouse effect of Venus, was deeply concerned about the megaforces that determine planetary fates.

In covering climate change so extensively then, the new Cosmos is living up to the legacy of its original creator.

Note: For those who miss it on Sunday, Cosmos also airs Monday, June 2 at 9 p.m. on National Geographic Channel with additional footage.

MORE HARD-HITTING JOURNALISM

In 2014, before Donald Trump announced his run for president, we knew we had to do something different to address the fundamental challenge facing journalism: how hard-hitting reporting that can hold the powerful accountable can survive as the bottom falls out of the news business.

Being a nonprofit, we started planning The Moment for Mother Jones, a special campaign to raise $25 million for key investments to make Mother Jones the strongest watchdog it can be. Five years later, readers have stepped up and contributed an astonishing $23 million in gifts and future pledges. This is an incredible statement from the Mother Jones community in the face of huge threats—both economic and political—against the free press.

Read more about The Moment and see what we've been able to accomplish thanks to readers' incredible generosity so far, and please join them today. Your gift will be matched dollar for dollar, up to $500,000 total, during this critical moment for journalism.
