““Collectively, we put 90 million tons of global warming pollution into the atmosphere every 24 hours,” Gore explained. “Twenty percent of it will still be there 10,000 years from now. It’s adding up.” “
I’d wager it will all be around somewhere 10,000 years from now. Just as it was here 1 million years ago.
The number I’ve heard for the half-life of a molecule of CO2 in the atmosphere is 100 years, much shorter for any other species of GHG. Just like Al Gore. I have no idea what he is talking about.
