SNL’s Pete Davidson joins Al Gore onstage during climate change event in Atlanta

Former Vice President Al Gore was back in Atlanta on Thursday for a three-day meeting to train activists on environmental justice and climate change.

Pete Davidson of “Saturday Night Live” joined the former vice president on stage, and those attending the training lit Twitter up with posts.

“Pretend the environment is a girl you’re in love with who just got engaged to someone else. The situation is dire but there’s still time,” Davidson reportedly told the trainees.

Davidson not only got Gore to talk to millennials in their language ...

The comedian and Gore announced their plans to bring back Captain Planet — with Davidson playing Captain Planet. Davidson is a regular cast member on "SNL," sure, but he also had a role in the Taraji P. Henson movie "What Men Want," which was filmed in Atlanta. He appeared in scenes filmed at Woodruff Arts Center.

Captain Planet was created by Ted Turner and Barbara Pyle aired on TBS in the early 1990s to teach children about saving the Earth.

Gore and Davidson appeared to be a hit with the group.

The Climate Reality Project continues through Saturday. This is the 40th time Gore has hosted this kind of training, but the first time he's included "A Moral Call to Action on the Climate Crisis," an interfaith mass meeting at 7 p.m. Thursday at Ebenezer Baptist Church, featuring the historic church's pastor, the Rev. Raphael G. Warnock, and the Rev. William J. Barber II, a 2018 MacArthur fellow.

“The climate crisis, as many of us have said for a long time, is not a political issue,” Gore told The AJC in January. “It is a moral and spiritual issue for the survival of humanity.”
