The effects of global warming are economic and social changes caused by greenhouse gas emissions . There is , and that human activity is a major driver [1] . Many of the effects of climate change, such as the retreat of glaciers [2] , earlier flowering plants [3] , and changes in agricultural productivity [2] are already observed today.
The future effects of climate change will vary depending on [4] Two main areas of policy aimed at solving the problem of climate change are reducing human greenhouse gas emissions and adapting to the effects of climate change [5] . Geoengineering is another policy option [5] .
In the short term, climate change policies can have a positive long-term effect. [4] [6] Strict can limit global warming by about 2 ° C by 2100 , or lower. An increase in global energy consumption , and an increase in fossil fuel production [7] , can lead to global warming of about 4 ° C [8] [9] . Higher temperature increases will significantly complicate adaptation [10] , and will increase the risks of negative consequences [11] .
Definition
The term “climate change” means the global change in temperatures that have been preserved for a long period of time [12] [13] . The World Meteorological Organization defines this period as 30 years [12] . Consequences may include global warming, changes in rainfall , and an increase in the frequency of . Climate change can be caused by natural causes, such as anthropogenic factors , changes in solar activity , or changes in atmospheric composition [14] . Any anthropogenic impact on climate change can occur against the backdrop of natural climatic changes [14] . In addition, human activity can increase or decrease climate vulnerability (for example, population growth offshore, or in arid regions) [15] .
In addition, the term “anthropogenic factor” refers not only to the natural human impact on the environment, but also to the artificial one [16] .
