Fears over a US-China cold war typically focus on disruptions to trade or even a potential military clash in the South China Sea. But there's another potential threat posed by escalating tensions, writes Minxin Pei for Project Syndicate: worsening climate change. "As it stands, China produces over nine billion metric tons of carbon dioxide per year, making it the world's largest emitter. The US comes in a distant second, emitting about five billion metric tons annually. If these two countries, which together are responsible for 38% of annual global CO2 emissions, are unable to find common ground on climate action, it is all but guaranteed that humanity will miss its last chance to prevent catastrophic global warming," Pei writes. "A Sino-American cold war would make such an outcome far more likely. The US would insist that China drastically cut its emissions, because it is the world's number one polluter in absolute terms. China would counter that the US bears more responsibility for climate change, in both cumulative and per capita terms. Locked in geopolitical competition, neither country would be willing to budge. International climate negotiations, already monumentally challenging, would end in deadlock. Even if other countries did agree on measures, the impact would be insufficient without the US and China on board." |
