Impact of climate changes on population vital activities in Russia in the early 21st century

The study substantiates the approach to the assessment of impact of climate change on vital activities of population in Russia in the face of increasing climate extremes. The obtained results reveal the occurrence of the essential climate extreme events over the period 1991–2013 in Russia that are vital for population activities. Annual amounts of interdiurnal temperature differences and pressure were calculated. Propagation of heat and cold waves, trends and frequencies of daily precipitation extremes were evaluated. The map "Zoning the territory of the Russian Federation by natural living conditions of the population" adapted for modern climate (2001–2010), illustrates the climate changes in the early 21st century. The modern warming of climate has led to a significant easing of discomfort in the territory of Russia. The steady decline of the absolutely unfavorable zone resulted from the expansion of less unfavorable areas is observed, especially in the Northern and Arctic regions. In the south the boundary of unfavorable territories shifts toward the north. It results in the expansion of the conditionally unfavorable area in West Siberia and in the south of East Siberia. In European Russia the favorable area expands and shifts far to the northern regions.
