Spatial patterns of the climate response to cumulative emissions

《巴黎气候协定》阐述了减缓气候变化的挑战，并强调需要将全球气温升幅限制在比工业化前气温高1.5至2°C的范围内。要实现这一雄心勃勃的目标，就需要作出协调一致和持续的努力，减少温室气体排放，以尽量减少气候变化达到危险程度的风险。这些努力必须基于对气候系统将如何应对人类温室气体排放以及排放水平与巴黎协定中通过的气候目标相一致的科学理解。

The Paris Climate Agreement has articulated the challenge of climate mitigation and emphasized the need to limit global temperature increases to between 1.5 and 2°C above pre-industrial temperatures. Meeting this very ambitious goal will require concerted and sustained efforts to decrease greenhouse gas emissions so as to minimize the risks of dangerous levels of climate change. These efforts must be informed by a sound scientific understanding of how the climate system will respond to human greenhouse gas emissions, and what level of emissions are consistent with the climate targets that have been adopted in the Paris Agreement.
