Remember how, in A Clockwork Orange, the protagonist was forced to undergo a reeducation procedure called the "Ludovico Technique," whereby he was given a powerful drug and then, with eyes pinned open, forced to watch disturbing content on television? 

This is what springs to mind when I think that someone might make me watch David Letterman's return to television for the latest season of National Geographic's series on climate change. 

In the series, dubbed The Years of Living Dangerously (no, not Mel Gibson's 1980s romance flick), a rather self-serious Letterman is seen donning his hipster beard as he travels to India to discuss "environmental issues" with the country's prime minister. 

"My goal here is a conversation — containing several points both personal and with regard to environmental issues and climate change," Letterman said in a recently released behind-the-scenes video, teasing his preparation for his interview with [Indian Prime Minister] Modi.

The show's producers, David Gelber and Joel Bach, explained to NBC that they chose Letterman for his passion: 

"I've created, excuse the expression, kind of a love affair with this," Letterman in a promo teaser said of his passion for climate change, particularly clean energy. "Think about the coal-fired, dangerous, smoke-belching generating plants, and then you look at this and it's friendly. There's something very appealing about this, and it's smooth. Look at this. I can touch it and it's safe."

Letterman is just one of many celebrities, however, who host the series. Based on this season's roster you can expect to be schooled on the science of climate change by intrepid environmental researchers like Sigourney Weaver, supermodel Gisele, Jack Black, America Ferrera, and others.
