The scientific research and assessment promote the progress of the international response to climate change,as well as national action. More scientific evidences show that anthropogenic activity is the main cause of global warming. The research scope of climate change impacts,adaptation and vulnerability is expanding and deepening. The problem of regional level even sub-national level has reached highlighted. Achieving the goal of 2 ℃ temperature control has reached consensus. The benefit assessment of policy coordination and integrated into related policies in different areas has been the research emphasis. The future research and action of China's response to climate change should be in four aspects:firstly,it needs to strengthen the research of different disciplines and cross-cutting areas in particular,such as related 1.5 ℃,land use,and oceans,as well as cities aspects. Secondly,the research on domestic low-carbon transformation strategy and international negotiations should be strengthened. Thirdly,the climate service system should be established. The ability of climate change adaptation should be promoted gripped with disaster risk management. Finally,the energy innovation should be realized through building energy Internet,so as to accelerate the domestic energy revolution and the economic development of low carbon transformation.
