Al Gore flubbed the name of activist Greta Thunberg as he tried to commend her as a leader of the movement to tackle climate change, a cause he has long championed.

"When morally-based, social revolutions gain the momentum necessary when the young generation takes on the cost," the former vice president said at the World Economic Forum in Davos, Switzerland. "Greta Thunberry, and she is quick to deflect to all of the others who have followed her lead and joined her in leading — this is a global phenomenon."



Gore, 71, also tweeted out a photo with Thunberg on Wednesday. "Great to see @GretaThunberg at #WEF20 today," he said. "Once again, I was struck by her potent and sobering call to action. Nobody speaks truth to power as she does: 'Our house is still on fire. Your inaction is fueling the flames by the hour.'"

The 17-year-old Thunberg said world leaders have been "cheating and fiddling around with numbers" when it came to dealing with climate change. "My generation will not give up without a fight," she said in a Tuesday speech.

The former vice president has been an outspoken critic of U.S. climate policy, but Gore has been accused by many critics of being a hypocrite when it comes to his own personal approach to climate change. A report from 2017 found that just one of his houses used over 20 times the amount of energy of an average home in the United States.
