Though it’s even questionable that climate change is largely driven by human activity, U.S. CO2 emissions have already been in decline since 2006 nonetheless, so harping on that point is dumb.
Any “solutions” that depend on a global reduction in CO2 emissions are dependent on Chinese and Indian economic policies, thus not solutions worth discussing in a U.S. domain.
I recommend to anyone who believes in reversing climate change as a solution to move to either China or India to vote in their elections, as that’s where those useless opinions might possibly be useful.
