So we know what we need to do, and we have tools available to achieve our goals. MEF leaders can therefore have confidence in adopting the interim and long-term targets recommended by the scientific community: keeping warming to below two degrees Celsius; peaking emissions within the next decade; and at least halving global emissions by 2050 versus 1990.
如此看来，我们已经知道了我们该做什么，我们有现成的工具来帮助我们实现目标。这样一来，MEF会上的各国领袖们就应该更有信心，实现我们中长期的目标：将全球温度降低2摄氏度，在10年后碳排放量达到最大峰值，到2050年将碳排放至少减少到1990年水平的一半。这也是科学界一致公认的目标。
