A home to one-fifth of the human population, South Asia is facing the threat of heat waves that cannot be survived without protection owing to the rise in global warming.
A new study indicates that the without the decrease in carbon dioxide emissions, deadly heat waves can begin soon and strike the regions of Pakistan, India and even Bangladesh. Without taking considerable action, the climatic change can be devastating to the regions sheltering one-fifth of humans i.e. more than 1.5 billion people would get exposed to the humidity and lethal heat in the near future with the increase in the emissions of carbon.
The study also indicates that according to the current trajectory of the carbon emissions, the heat waves are likely to hit the regions within a few decades and would cause asevere devastating impact on the fertile lands of Ganges River Basins along with fertile Indus which can hamper the food supply of the region.
THE MEASURES TAKEN
The new Paris Climate Agreement, in 2015, that was signed for cutting the carbon emissions, can reduce the risks poses to the region if implemented soon. The vulnerable parts of the region can be benefitted majorly by the cuts made in the carbon emissions.
In Science Advances, the study was published, which demonstrated the potential future heat and rise in humidity in South Asia by using the climate models. South Asia is deemed to be the warmest regions of the world as it is.
THE IMPACT OF THE WET BULB TEMPERATURE
The wet bulb temperature, which is a combination of high humidity and high temperature, poses the most deadly results without any protection against it. Even with the wet bulb temperature of 35 degrees Celsius, the human body cannot protect itself to survive even for few hours.
In 2015, more than 3500 people were killed in India and Pakistan owing to the heat wave with the wet bulb temperature of 50 degrees Celsius.
As of now, only 2% of the Indian population faces 32 degree Celsius of wet bulb temperature but it is expected to get exposed to 70% of thepopulation without the subsequent cuts in the emission of carbons.
A large scale migration of people from one place to another is expected soon enough with the constant rise in temperature. Meanwhile, the officials are still trying to make changes for addressing the changes in climate since, without it, the heat wave is going to prove catastrophic.
