As Hurricane Florence slammed the East Coast and Typhoon Mangkhut hit the Philippines, a thunderous Al Gore told a San Francisco audience climate change is exacerbating extreme weather events.

"Every night on the television news is like a nature hike through the Book of Revelation and we’ve got to connect the dots between the cause and the effect," Gore said.

The former vice president was in town for the Global Climate Action Summit hosted by Gov. Jerry Brown from Sept. 12 to 15. Gore led a talk titled "The Importance of Renewed Ambition."

Gore criticized climate change deniers and he compared their disbelief to President Trump’s denial of the death count in Puerto Rico from Hurricane Maria.

"Some people evidently can still deny the reality," Gore said. "It’s a little bit harder to deny the 3,000 deaths in Puerto Rico from Hurricane Maria. C’mon. How far down that rabbit hole are people going to follow? This is utter insanity."

He also talked about people’s mistreatment of the planet saying, "We are treating the skies as an open sewer for carbon pollution." 

Business leaders, mayors, governors and activists from around the world have descended upon San Francisco for the Global Climate Action Summit this week. Participants are expected to introduce new ideas to address climate change and pledge trillions of dollars for spending on cleaner energy.
