There's no cooler name than President's Obama's Facebook address handle of POTUS, but his advocacy is sexy as well.

On Nov. 10, the POTUS joined Facebook to share his advocacy about climate change.

"Hello, Facebook! I finally got my very own page. I hope you'll think of this as a place where we can have real conversations about the most important issues facing our country - a place where you can hear directly from me, and share your own thoughts and stories. (You can expect some just-for-fun stuff, too)," he wrote.

"I'm kicking it off by inviting you to take a walk with me in my backyard - something I try to do at the end of the day before I head in for dinner. I say this often, but that's because it's always at the front of my mind: We've got to preserve this beautiful planet of ours for our kids and grandkids.

"And that means taking serious steps to address climate change once and for all. Now, we've made a lot of progress to cut carbon pollution here at home, and we're leading the world to take action as well. But we've got to do more. In a few weeks, I'm heading to Paris to meet with world leaders about a global agreement to meet this challenge."

President Obama continued his Facebook message by asking everybody to pitch in on the fight against climate change.

"I hope you'll join me in speaking out on climate change and educating your friends about why this issue is so important," he said. "At a time when nearly three in four adults online use Facebook, this feels like a great place to do it. Share your thoughts in the comments, and pass this message on to folks you think need to see it."

"If we're all in this together, I'm confident we can solve this and do right by future generations."

And President Obama even got a welcome message from Facebook founder Mark Zuckerberg himself, who wrote, "Welcome, President Obama! I'm excited that you've joined our community, and I look forward to seeing how you engage with people here on Facebook."

President Obama's Facebook profile describes him as "Dad, husband, and 44th President of the United States."
