标题：MEDICAL AND DEMOGRAPHIC CONSEQUENCES OF CLIMATE CHANGE AND THE ASSESSMENT OF COMFORT LEVEL OF WEATHER-CLIMATIC CONDITIONS IN THE VOLGA FEDERAL DISTRICT
摘要：The paper provides a brief analysis of research on the impact of global climate change on human health. Using Tatarstan as an example, the paper discusses medical and demographic consequences of the extreme heat wave of the summer of 2010. Assessment of the Volga Federal District (VFD) bioclimate conducted with the help of certain biometeorological parameters allowed evaluating modern global and regional changes of weather-climatic conditions. The main emphasis was placed on spatial and temporal analysis of both the integral pathogenicity index (I) and its individual components for the district territory. In VFD, aggravating weather conditions increase from southwest to northeast. Summer months are associated with comfort weather conditions. In winter, the air temperature pathogenicity index and interdiurnal temperature fluctuations contribute the greatest to I&59; in summer, the role of cloudiness and humidity pathogenicity indices increases. The contribution of wind speed and interdiurnal pressure fluctuations to I is insignificant in all seasons. Analysis of the frequency distribution of I showed that comfort weather conditions (over 50 % of cases) occur in May–August, aggravating weather conditions occur in March-Appril, and harsh weather conditions in more than 50 % of cases occur in January–February and November–December. Calculation of biometeorological indices allows forecasting risk of thermal hazard under extreme meteorological conditions.
