GLOBAL WARMING - PHYSICS AND GEOPOLITICS (Review). 2. Policies to mitigate the negative impact of climate change and adapt to it

Introduction. Reducing the negative impact of global warming and adapting to its devastating effects is an urgent global problem. Its decision is actively taken care of by politicians, leading world organizations and the expert community. Problems. Political, financial and economic, innovative, scientific and technical approaches and measures to reduce and / or neutralize climate change are widely discussed. World organizations - IPCC, IEA, WMO, IMF, etc. - are involved in solving the problems. Purpose. Assess the state of the problem, present the results of research and measures and tools for their implementation to reduce the greenhouse effect and / or adapt to its negative impact. Materials and methods. Authoritative literature sources with analysis of approaches, measures and tools to reduce greenhouse gas emissions, including the diversification of the fuel and energy balance of world energy resources, were used. Possibilities of adaptation to climate change are considered. Results. The main approaches and mechanisms of man-caused nature to actually reduce greenhouse gas emissions and global temperature in the 20th century are identified and their estimates for the period up to 2050 are given. The crucial role of RES and energy efficiency in the use of energy resources has been confirmed. Conclusions. It is likely that by the middle of the 20th century the world economy can be brought to a state of low-carbon development primarily through the use of renewable energy, energy efficiency, diversification of primary energy resources and their decarbonization, which will significantly reduce annual emissions of 10 carbon .
