Gerald Meehl of the National Center for Atmospheric Research (NCAR) and colleagues that are more pessimistic about the evolution of global warming. According to their research published in Science, even assuming a net stop all emissions of greenhouse gases due to human activity, global warming is inevitable.
At the end of 21ème century, in the best case, the average global air temperature and win 0,5 ° C and sea level 11 cm. The researchers carried out the summary results of many simulations of two types of climate models - the Parallel Climate Model (PCM) and the Community Climate System Model 3 Version (CCSM3) - conducted on supercomputers at NCAR and laboratories of the US Department of Energy and the Japanese Earth Simulator.
Despite differences between the two on the intensity of the phenomenon, the trend remains the same: the increase in global temperature and sea level over the next 100 years. For researchers, this inevitability can be explained largely by the thermal inertia of the oceans and the long life cycle of carbon dioxide and other greenhouse gas in the atmosphere. The performed model simulations (not taking into account
the impact of melting glaciers and ice caps) confirm the need to act strongly to prevent further aggravate the future situation.
