Migration: Of the 17.7 million internal refugees, the International organization for Migration (IOM), the tracked, had to leave until September of 2018 of two million people because of disasters, in conjunction with the weather and the climate of your home. Such as droughts, Floods and severe storms. global warming: as a result of climate change heat to take waves: The number of affected people increased from 2000 to 2016 estimated 125 million. This is mainly due to the fact that heat waves lasting an average of 0.37 days longer than in the period between 1986 and 2008. Experts expect that such events in the frequency, strength and duration will continue to increase. warming of the oceans: in 2018, there were new record values for the so-called heat content of the oceans in the upper 700 meters, and in the upper 2000 meters of the waters. According to the report, more than 90 percent of the as a result of global warming, the additional energy going into the oceans. The heat content of the oceans is a measure of the Energy build-up. the decline of the glacier: According to preliminary analysis by the world glacier monitoring service (WGMS) glacier mass in the water economy year 2017/18 31.
