We have all been experiencing the excessive heat even in our own homes.
Well, according to a new study, it will become worse 50 years from now if we don’t change our ways.
About 2 to 3.5 billion people around the world, mostly those who can’t afford air-conditioning, will be living in a climate that is too hot a human body can handle.
With every 1.8-degree Celsius increase in the global average temperature yearly, about a billion or so will end up with unlivable heat according to ecologist Marten Scheffer of Wageningen University in the Netherlands, co-author of the study.
We humans have a sweet spot of temperature as a group of international scientists have studied — average annual temperatures between 11 to 15 degrees Celsius.
We can live in warmer and colder places than that, but the farther we are from the sweet spot, the harder it gets either warmer or colder.
The scientists are looking places like parts of Africa, Asia, South America, and Australia that will likely to experience the effects of climate change first.
Our future highly depends on the climate altering choices we make and our population growth.
