At Davos, Al Gore says climate crisis is worsening

Former U.S. Vice President Al Gore warned Thursday that the world's climate crisis is worsening, as he provided an updated to the World Economic Forum about fighting global warming.

"We could take the whole session talking just about the new scientific evidence of the last few weeks and months," said Gore, who shared last year's Nobel Peace Prize for his efforts to fight climate change, adding that the "climate crisis is significantly worse and unfolding more rapidly."
