American scientists found that heat waves will be much larger in size by the middle of this century. About it reported in a press release on Phys.org.
According to the scenario of moderate greenhouse gas emissions, the area that will encompass the extreme heat, will increase by 50-80 percent. At the maximum increase in the concentration of carbon dioxide, the area affected can be doubled. This will increase the number of people that will undergo thermal stress will increase the risk of premature death among the elderly and other vulnerable groups of the population. Also will increase the load on the grid because of the larger number of working air conditioners.
In addition, the expected increase of such indicators as the duration of heat waves and its intensity. According to the researchers, it is consistent with the predictions about climate change and global warming.
“If over a densely populated area established a large and prolonged heat to meet peak demand for electricity will be more difficult than in the case of multiple areas with fewer heat waves, which together are the same size,” says Tony Barnston (Tony Barnston), one of the authors of the study.
