Kerry’s claim that ‘we have nine years left’ to avert the climate crisis

Outlet: Washington Post

Washington Post: A. Scott Denning, a climate scientist at Colorado State University, said he found the political fixation with 12 years to be “frustrating.” As he put it, “Every bit of coal, oil and gas burned anywhere adds to the CO2 in the air and reduces the efficiency of Earth’s cooling to space, so every last lump contributes to heating the climate. That was true 20 years ago, and it will continue to be true 12 years from now. And once it’s in the air, it’s not going away.”
