The article is devoted to the analysis of the climate change studies’ history in the Krasnoyarsk Territory (Krai). The authors identified four stages; each has some characteristic historical events, the results of scientific research, which influenced the development of regional climatology and increased knowledge about the Krasnoyarsk Territory’s climate. The dynamics of the scientific knowledge development concerning climate was possible to study on the basis of the content analysis of both the works of the first Siberian climate researchers (A.I. Voeikov, A.F. Middendorf, A.P. Stepanov, etc.), and modern scientific works (D.F. Zhirnova, V.S. Myglan, B.T. Kochkin, etc.). The study’s result was an orderly knowledge system about the history of studying climate change in the Krasnoyarsk Territory. A tendency has been found to study the regional climate not only from the point of its change towards an increase in the average air temperature, but also from the point of the influence of anthropogenic factors on the increase in climatic indicators and climate change – on the life quality for the population of the Krasnoyarsk Territory.
