People already live in heat stress on the brink of human survival

A team of researchers from Monash University and Hasanuddin University in Indonesia found that

some people who are in tropical regions already live under heat stress conditions. The problem is that they are approaching the upper limits of human survival

Climate models used forforecasts of thermal conditions around the world are usually based on data from weather stations in relatively densely populated areas. They do not include provisions for people who live in so-called informal settlements. To remedy the situation, scientists placed heat sensors in about 100 homes in Makassar, Indonesia, a community in the tropical part of the country. The researchers suggest that conditions at Makassar are likely typical of many such settlements in the tropics, areas home to about 370 million people in East and Southeast Asia alone.

It turned out that during the rainy season 80%sensors recorded temperatures that were above established health thresholds. At this temperature and humidity conditions, conditions are believed to have adverse effects on human health. In several cases, sensors recorded temperatures that represent the upper limit of human survival.

Millions of people living in many parts of the worldalready live in heat conditions that are harmful to their health. Many of them are actively engaged in manual labor in order to survive. The authors of the work noted that conditions in such places will worsen as the planet continues to heat up.
