In the future, the temperature of China will continue to increase, by the end of 21st century, might increase 1.3-5.0 ℃. Precipitation might increase 2%-5% nationally, with the northern part increase 5%-15%, while no significant change in southern part. Heat waves, extreme drought events might increase; sea level might continue to rise.
In the REPORT, more than 10 experts and scholars from Beijing Normal University, Institute of Geographic Sciences and Natural Resources Research, CAS, Institute for Urban and Environmental Studies Chinese Academy of Social Sciences, and the National Disaster Reduction Center, gave comprehensive assessment of the achievements of China’s response to the risks of climate change, and suggested addressing the challenges by integrated risk governance.
