The region of China should become the most deadly heatwave zone: report

New scientific research suggests that unless there are strong reductions in carbon emissions, climate change will lead to damp heat waves that could push the area "against the limits of roominess" of 39, here 2070.
The results of the study The plain, which includes the capital Beijing, is particularly worrying as many of the 400 million inhabitants of the region are exposed to extreme weather conditions.
According to the study, heat and high humidity can create conditions that kill healthy people within six hours. "This place is going to be the hottest place for deadly heat waves in the future," said Professor Elfatih Eltahir, at the Massachusetts Institute of Technology (MIT), which has directed the new study.
"China is currently the largest contributor to greenhouse gas emissions, with potentially serious implications for its own population," said Eltahir, who specializes in hydrology and climate science . livability of the most populous region of the most populous country on the planet, "explains Eltahir
Impact of Climate Change
Projections are based on research showing that humans can not survive a certain threshold of temperature and humidity.
This threshold was determined by a measurement called wet bulb temperature (WBT), which is measured by wrapping a damp cloth around the bulb (or sensor) of a thermometer, so that evaporation water can cool the bulb.
In a wet bulb temperature of 35 degrees Celsius, a healthy person may not be able to survive outside for more than six hours, showed a study.
The MIT study shows that the risk of the new study has shown that if greenhouse gas emissions are not cut, the fatal threshold temperature of 35 degrees Celsius will be reached several times in the northern plain between 2070 and 2100.
An increased vulnerability to heat occurs because irrigation exposes more water to evaporation, resulting in higher air humidity than that which would otherwise be present and exacerbating the physiological constraints of temperature, according to the report's authors. "Irrigation exacerbates the impact of climate change," said Eltahir. He added that there had been a substantial increase in extreme heat waves in the region over the last 50 years.
The report states that in the usual scenario of greenhouse gas emissions, the plain concludes that conditions "may require the simultaneous development of effective measures of public health adaptation to avoid deadly impacts. future heat waves. "
