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

“To save computer time, the research community typically evaluates future climate scenarios every decade rather than every year, choosing multiples of 10,” Shindell told The Fact Checker. Swain said that if he were to revise Kerry’s comment, he would drop any reference to years and render this way: “The scientists have been telling us for decades that we need to act as fast as possible to avert the worst consequences of climate change. Moreover, 2030 is not a magic date when future efforts to combat man-made climate change will no longer be effective; it just means that if emissions are not reduced by 50 percent by 2030, the task will become even harder.
