This includes the US, which, although not willing to make any promises, nevertheless is the most active country in developing new energy sources to reduce greenhouse gases. This is because global warming will create heatwaves, storms, and flooding that will hit the US as hard as anywhere else, so global warming cannot be fobbed off as "the other guy's problem."
包括不願給予減量承諾的美國，卻是最積極發展新能源以降低溫室氣體的國家之一，因為暖化造成的熱浪、暴雨、河川氾濫也同樣在重擊美國，氣候暖化不是「別人家的事」。
