New York:
Another killer is ready to take the lives of human beings after the corona virus, a UN report is warning of the serious dangers of global warming faced by billions of people. The report warns that incoming heatwaves will prove to be deadly enough to kill people.
Early climate change models suggested that if pollution continued unabated at the same rate, about 100 years later, unusual heat waves would be created that would be unbearable for humans, further research says. The report of the 4,000-page Intergovernmental Panel on Climate Change will be released in February 2022. However, some of its contents have been released.
The report paints a bleak picture, with an average 1.5 degree Celsius rise in global temperatures causing 14% of the world’s population to experience a severe heat wave every five years. Will face and if it increases by another half a degree, it will expand to 1.7 billion people. It will affect the major cities of the most developing countries, from Karachi to Kinshasa, from Manila to Mumbai and from Lago. To Manaus
It is not just the result on the thermometer that will make the situation worse, but the high moisture content with heat that makes it deadly. That is, if the air is dry, it will be easier to spend the day even in high temperatures, but if the humidity in the air is high, it becomes difficult to save lives even in low temperatures.
This is called wet bulb temperature. Experts say that if the weight bulb temperature exceeds 35 degrees Celsius, it becomes difficult for a healthy adult to survive, even if he has access to shade and drinking water. Colin Raymond, lead author of recent research on heat waves in the Gulf, says that when the weight bulb temperature is too high, the humidity in the air makes the sweat process ineffective in cooling the body. Thus, after 6 hours, the organs of the body stop working and if artificial means of getting cold, such as air conditioner, are not accessible, death will be certain.
This deadly heat has been experienced before. In 2015, a similar heat wave in Pakistan and India killed more than 4,000 people. The wet bulb temperature then reached only 30 degrees Celsius. Earlier, in 2003, more than 50,000 people were killed in a heat wave in Western Europe, even though the temperature of the wet bulb did not reach 30 degrees Celsius.
Experts say the worst effects could be avoided if global warming is limited to 1.5 degrees Celsius, in line with the Paris Agreement. But there will still be many areas where temperatures will rise far above the global average and have far-reaching effects.
