Despite the fact that they've been using the “climate action is useless because China won't act” canard as one of their favorite arguments for years now, Republicans' outraged response to the historic climate deal between China and the U.S. probably took noone by surprise.
Because that's the thing: it is historic. For the first time ever, China has agreed to put a cap on the emissions produced by its rapid, voracious economic expansion. While it's certainly not true that the U.S. taking responsibility for its share of global warming pollution wouldn't have had a meaningful impact anyway, it also can't be ignored that averting runaway climate change would be nearly impossible if China's emissions keep growing unabated.
But to say it's historic that two of the world's biggest economic superpowers—and the world's two largest carbon polluters, together responsible for nearly half of global emissions—have agreed to begin to lower their respective contributions to global warming is not the same thing as saying that the deal President Obama and Chinese President Xi Jinping struck is enough to get the job done.
The most important issue, of course, is the emissions targets themselves, which come nowhere near what climate scientists say are needed to prevent catastrophic warming. We must lower global warming pollution 80% below 1990 levels by mid-century, yet the US is still using 2005 as its baseline, and has only committed to lowering emissions 26-28% by 2025. China, meanwhile, needs to see its emissions peak by 2020, climate scientists say, but has only committed to doing so by 2030.
