If an international agreement to protect the world’s climate is to be reached, much greater action to reduce CO2 emissions will be needed on the part of the US, as well as binding commitments on China’s part to reduce its carbon burden. Ultimately, though, without US-China cooperation, a global climate agreement will be held hostage.
若一项旨在维护全球气候公约的国际协议达成，美国方面须采取更大行动削减二氧化碳排放量，而中国方面也应履行承诺削减其碳排放量。但若美中最终不合作，全球气候协议将受到挟制。因此，美中僵局是一个世界问题。
