Since the signing of the Kyoto Protocol in 1997,the road to-wards international cooperation in responding to global warm-ing has been quite bumpy.Following the aborted Copenhagen Agreement,the Paris Agreement in 2015 strenuously reunited various countries based on the principle of individualized contri-butions.Yet,in the recent UN Framework Convention on Cli-mate Change 26th summit meeting (COP26) held in Glasgow,US government leaders again pointed the finger at China,accus-ing China of not doing enough and setting insufficient goals for reducing carbon emissions.However,the US has only symboli-cally signed the Kyoto Protocol—having never obtained the ap-proval of Congress—and has treated the Paris Agreement with a wavering position,seemingly forgetting the fact that the US is leading the world in various indicators of carbon emissions and,according to its commitment,future emissions will remain high.For this,we have to let the data speak.
