Where are temperatures rising fastest due to global warming?

Global warming - an increase in the average temperature of the atmosphere near the earth's surface and oceans observed since the middle of the 20th century, simultaneous cooling of the stratosphere and the expected future warming resulting from the Earth's radiation imbalance. The total increase in average temperature from 1850-1900 to 2003-2013, calculated on the basis of the longest available data set, is 0.78 [from 0.72 to 0.85] ° C [1]. The essence of the problem related to the explanation of global warming is to determine the extent to which this phenomenon is affected by human activity and in which natural factors. The Intergovernmental Panel on Climate Change (IPCC) believes that "Human impact on the climate is obvious, as shown by the increasing concentration of greenhouse gases in the atmosphere, positive radiation enforcement, observed warming and understanding of the climate system" and "It is extremely probable [in accordance with the Convention] the probability assumed in the report is 95% -100%] that man has a dominant influence on warming observed since the mid-20th century. "[2] [3]. In the 20th century, natural factors such as solar activity and volcanoes caused only a slight warming in comparison to the period before the industrial revolution [A 1] [A 2] [A 3]. These conclusions were supported by more than 45 scientific associations and academies [A 4], including all national academies of science in the eight most industrialized countries [4] [5].
