As if we thought Ian Somerhalder couldn't get any hotter the actor was spotted happily waving to his fans while making an appearance on Extra on Wednesday April 23rd in Universal City, California.

The 35-year-old looked to be in great spirits during an appearance on "The Tavis Smiley Show" the day before.

According to Just Jared, "The Vampire Diaries" season 5 star was asked how he is making the climate change issue sexy and attractive for his younger fans. Nina Dobrev's ex-boyfriend turned serious for a moment and revealed his method.

He said, "How do you make it cool? How do you make it sexy? Well one cool thing about it is that the most underdeveloped, underutilized, under appreciated, undervalued people in the world are our youth.

"They make up half the population and they're going to be running the world so why wouldn't we give them the tools to ultimately be able to do that?"

The CW star went on to say, "If it takes a vampire soap opera, which has been such a great five years of story-telling that really resonated with this audience and built this audience.

"My whole thing is... I don't know how to do very much in the world, but leveraging entertainment value and using social media to create quantifiable global change, that I know how to do."

According E! News, later on in the week Somerhalder stopped by "Chelsea Lately" where he talked about how he became involved with "Years of Living Dangerously," the new Showtime documentary series focusing on climate change.

He explained, "When your manager calls you and tells you James Cameron, Jerry Weintraub and Arnold Schwarzenegger are producing a show for Showtime that's Harrison Ford, Don Cheadle, Matt Damon, Lesley Stahl, Thomas Friedman, and then says you, I jumped out of my chair."

Molly Swenson's rumored boyfriend went on to say, "It's a nine-episode docu-series [that] shows the world these insane things that are happening."

The hunk added that he's "beyond grateful" the program was developed.
