Al Gore: "The climate crisis is now the biggest health threat facing humanity."

"Unless we stop the use of the sky as an open sewer... billions of people will find themselves living in areas where it's no longer safe to stay outside for more than a couple of hours."

"And of course that mobilises climate refugees in much larger numbers."
