Scientists say increasing greenhouse gas emissions in densely populated parts of South Asia will push temperatures past the " upper limit on human survivability . " They published their finding in the journalScience Advances .
The human body can only withstand so much heat , and the authors of the current newspaper note that 35 ° ascorbic acid ( 95 ° F ) pushes that upper limit . Anything above that will result in death " even for the fittest of human beings under shaded , well - give vent conditions . "
This 95 ° F maximum is what ’s called awet bulb(TW ) measuring . Like the heat index , TW conceive humidness as well as air temperature , which means it ’s a more accurate mensuration of how well our bodies can by nature cool themselves down . The muggy the climate , the higher the TW . And in places like India , the TW is reasonably darn gamey .

The research squad conflate climate information from Pakistan , Nepal , India , Bangladesh , and Sri Lanka with information about current and estimated succeeding greenhouse petrol emissions in those countries .
With these unite datum point , they created two potential scenario : the " job as usual " modeling , in which the region ’s rapidly growing economy continues to produce more and more air contamination ; and the " mitigation " model , in which something is done to slow , if not stop , emission .
Neither outcome bet peculiarly ripe , but there was a bounteous difference between them . The business - as - common modelling argue that ordinary temperatures will well attain TW 95 ° F by the year 2100 . For the mitigation model , that figure was closer to TW 88 ° F .

These were just the total averages . Some region were far worse off than others . In either situation , poorer agrarian communities in India will be pip the hardest — a particularly grave upshot in areas where most people subsist without air conditioning .
" This disparity raises important environmental Justice Department questions beyond the scope of this cogitation , " the authors indite . " The finding … may present a important quandary for India because the continuation of this current flight of rising emissions will likely impose significant added human wellness risks to some of its most vulnerable populations .
