After the end of the Cold War，New changes have taken place in the international security situation，the threat of military threats to international security has been further reduced，and the threat of non-traditional security issues such as climate change has increased significantly. The IPCC’s previous assessment reports confirm the trend of global warming. Climate disasters and the resulting regional conflicts have a devastating impact on human social development and pose a major threat to international peace and security. The United Nations has actively promoted the governance of non-traditional security issues such as climate change. Since 2007，the Security Council has held four debates on climate security issues to promote the formation of international consensus. This has injected new impetus into the international response to the climate change process. As a permanent member of the Security Council and the largest emitter of greenhouse gases，China may also face greater pressures on emission reduction and funding donation. In order to show the image of my responsible big country and lead the global response to climate change，first，must actively participate in，promote and guide climate security issues；second，actively carry out international cooperation and response to climate risks；third，accelerate the development of domestic green and low carbon The fourth is to accelerate the construction of a climate-adapted society.
