The World Bank has disclosed that increasing temperature and humidity pose a severe threat to human health and outdoor productive activities.

This disclosure was made in a recent report titled ‘The Cold Road to Paris: mapping pathways toward sustainable cooling for resilient people and economies by 2050’.

According to the report, there is a substantial threat of severe heat, with the possibility of 60 per cent of the global land surface being exposed to very high heat extremes by the end of the century.

 It was further stated that South America, Africa, and Southeast Asia will likely be more exposed to very high heat extremes by the end of the century at 2°C warming.

The report read in part, “With current policy efforts, there is a significant threat of extreme heat. If global warming reaches 4°C, it is expected that 60 per cent of the global land surface will be exposed to unusually high heat extremes by the end of the century.

“At 2°C warming, approximately 20 per cent of the global land surface and tropical areas in South America, Africa, and Southeast Asia, where heat extremes are rare, will be exposed to unusually high heat extremes by the end of the century. Already in the 2020s, policy directions leading to 2°C warming will affect populations exposed to heat extremes differently than those leading to 4°C warming.

“With a 4°C scenario, it is anticipated that about 17 per cent of the world’s population (living mostly in the tropics) will experience unusual summer temperatures by 2025. By 2040, this increases to 50 per cent (mostly in densely populated areas in Southeast Asia, the Americas, and the Mediterranean).”

The report also stated that 96 per cent of the world population would encounter uncommon summer temperatures, which pose great challenges to health, food security, and livelihoods, undermining poverty reduction efforts.
