South Asia faces more heat due to climate change

DHAAA: The future of deadly heatwaves in South Asia is likely to experience more deadly heatwaves, with the region potentially having nearly triple the potential for lethal heat stress if global warming is not curbed, researchers said.
According to the American Geophysical Association, an international researchers, in this week’s study, the researchers met the target set under the Paris Agreement on Climate Change, limiting the temperature to 1.5 degrees Celsius during pre-industrial times. Scientific Association.
“The future looks bad for South Asia, but as little warming as possible can be avoided,” said climate scientist Motasim Ashfaq of the US-based Oak Ridge National Laboratory.
Ashfaq continued, with global temperatures already having temperatures above 1 degree Celsius, “there is no need for adaptation over South Asia today. There is no alternative to this in the future.”
The Intergovernmental Panel on Climate Change (IPCC) has said that global-heating emissions should decline by about 45% by 2030, compared to 2010 levels, to reduce warming by 2 ° C, higher in the Paris Agreement Temperature target.
A UN report said that prior to COP 26 UN climate negotiations in November, updated plans by 75 countries to reduce emissions needed major reductions to meet global climate targets.
The new study used climate simulations and projected population growth that estimated temperatures at temperatures of 1.5 and 2 degrees Celcius could experience stress at dangerous levels.
It looked at the predicted “wet bulb temperature”, which includes humidity and temperature, and aimed to more accurately show what people experience on a hot day.
Health experts and scientists say that at a wet bulb temperature of 32 degrees Celsius, labor becomes unsafe. He also said that at 35 degrees Celsius, the body can no longer cool itself.
If warming hits 2 ° C, the number of South Asians exposed to unsafe temperatures may increase two-fold, and nearly three times as many people can withstand deadly heat.
The study noted that South Asia accounts for a quarter of the world’s population and thus heatwave can have an impact on the production of crops in areas such as Punjab and Sindh in India and Punjab, such as West Bengal and Uttar Pradesh.
The study suggested that workers in cities such as Karachi, Kolkata, Mumbai and Peshawar could also be affected.
The study also noted that Pakistan and India already experience fatal heatwaves, with around 3,500 deaths due to one in 2015,
