摘要
Local climate changes differ significantly from global trends and require tailored mitigation practices. Here, we analyze the surface temperature data from the network of meteorological stations in the Southern Urals and the numerical experiments over the period from 1979 to 2012. The isolated greenhouse effect was evaluated using the global atmospheric general circulation model (ECHAM5). Simulations with constant concentrations of CO2 and CH4 at the level of the 1980s describe the real values of surface temperature better than scenarios in which the concentration of greenhouse gases changed according to observations.
