SUMMARY

Climate change is one of the most pressing environmental security issues and is of planetary significance. Еspecially climate changes caused by human activity are а threat to the sustainable and safe existence and development of the planet. They are inherently multi-layered and diverse. Climate changes lead primarily to global warming, the main cause of which is also the human activity. For minimizing or at least mitigating the effects of climate change and its impact on the quality of life of a human and society, the state and environmental security, in-depth comprehensive studies, as well as consistent effective efforts are required. Moreover, there is an urgent need to review and reassess both the traditional ways and tools for solving environmental problems, and their content and purpose­fulness, yet at the same time, the realities shaped in certain spheres should be assessed, and new mechanisms for adapting to new conditions should be developed.

Climate change is also one of the most serious economic risks. Various expert assessments indicate that climate change will have a long-term negative impact on global economic growth, labor productivity
and mass migration. Accordingly, the article discusses the Nordhaus, Weizmann, Dietz-Stern models for quantitative assessment of economic damage due to climate change. However, it should be noted that the estimates of economic damage from climate change differ primarily depending on whether the model takes into account the existence of a critical moment in warming, from which the damage to the economy begins to grow rapidly.

The results of the forecasts given in this article once again confirm the fact of huge losses and rising costs of the economy following climate changes.
