Disclosed the reason for extreme rain events across the planet
Scientists from the Potsdam Institute of climate change came to the conclusion that the increase in global temperature of half a degree increased extreme weather conditions that occur throughout the planet.
So, increasingly began to encounter heavy rains, thunderstorms, and prolonged heat waves. Article researchers published in the journal Nature Climate Change. About it briefly told in the press release on the website Phys.org.
Forecasting the effects of global warming to 1.5 or two degrees Celsius includes certain assumptions. For example, scientists can rely on different models of oceanic circulations. So, to avoid uncertainty, experts have appealed to the data of many years of meteorological observations.
Climatologists compared the two 20-year period 1960-1979 and 1991-2010 year between the average temperature on Earth has risen by 0.5 degrees Celsius ©. It turned out that by the end of this period of time increased to such meteorological factors as the length of the dry season and intensity of extreme rainfall. In addition, average summer temperature has risen more than one degree, and winters become warmer on average in 2.5 s.
According to the findings of scientists, these changes go beyond natural variability, that is caused by the burning of fossil fuels by man. The data are also consistent with models that showed that the increase in global temperature due to anthropogenic activities of two degrees will double the number of crop failures, reduce the availability of fresh water and increased frequency of heat waves.
