Billionaire venture capitalist Chris Sacca has a message for anyone who will listen: "The climate is f---ed. Even worse than it seems," he said in a 12-page letter to potential investors, obtained by Axios on Monday.

Sacca's climate-focused firm Lowercarbon Capital announced a new capital raise of $800 million on Thursday, which Sacca said will be used to "keep unf---ing the planet." This is the first time the firm has accepted outside money, according to Crunchbase, and it comes on the heels of the earth's hottest month on record: July 2021, according to new global research released on August 13 by the National Oceanic and Atmospheric Administration.
