Spatial patterns of the climate response to cumulative emissions

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.
