President Obama is now on Facebook.
But this is his personal page, and he's already been welcomed by commenters like Sheryl Sandberg, Katie Couric, the German government and Buzzfeed.
"So this has been my backyard for the last seven years," President Obama said in a video on his Facebook page.
The president took the opportunity to talk about climate change, something he's been talking about a lot lately.
"If all of America is joining around this critical project, then we can have confidence that we're doing right by future generations," the president argued.

But, on his new personal Facebook, the president made his case personally, bringing up the elusive White House fox, as well as his daughters.
"I want to make sure that the beauty of this particular national park, but also national parks across the country and our planet are going to be around for Malia, Sasha their kids, their grandkids, for generations to come," the president said.
