ABSTRACT
The scientific basis for addressing climate change comes mainly from the multi-volume climate change assessment report issued by the Intergovernmental Panel on Climate Change (IPCC), an international organisation that assesses climate change established in 1988. So far, IPCC has successively published 5 assessment reports on climate change. The fifth assessment report in 2014 pointed out that global climate warming will continue in the future, and the average surface temperature of the Earth by the end of the twenty-first century will rise by 0.3–4.8°C on the 1985–2005 basis. The report also evaluates the existing credibility of the main conclusions of extreme climate events and analyses the root causes of disaster risks from the perspective of “extreme climate events + vulnerability + exposure”, and integrates risk management into climate change actions of each country. The overall framework provides an important scientific basis.
