Scientists from the Max Planck Institute and the Cyprus Institute in their study describe a region of North Africa and the Middle East as a climate hotspot, a place where the number of days with extreme temperatures compared to 1970 doubled. According to scientists, threatens this region may be in the foreseeable future plagued by unfavorable temperatures so that it leaves its inhabitants.
During the hottest days of the temperature climbs to nearly 43 ° C. Scientists estimate that by 2050, temperatures could rise up to 45.5 ° C in 2100 and could reach up to 50 ° C. Such extreme weather, according to scientists had serious impacts on human health and society. In the area while living on half a billion people.
"Prolonged heat waves and desert dust storms can cause some regions become uninhabitable. Whole certainly lead to a migration of people," said Johannes Lelieveld, who led the study.
Based on the analysis of climate data since 1986 by scientists forecast temperatures by the end of this century. The account had two scenarios, secondly, that when in mid-century humanity manages to reduce its greenhouse gas emissions, and then a scenario where humanity restrict their emissions.
Research has shown that in both cases it appears that the area south of the Mediterranean must prepare for the searing temperatures and heatwaves.
Between 1986 and 2005 there heatwaves lasted an average of 16 days. Scientists say the heat wave could take up to 80 days in mid-century and up to 118 days at the end of the century. And if humanity would not reduce emissions of greenhouse gases could heat wave at the end of the century last for 200 days. Under such conditions, the area was hardly livable and people would leave the area.
