Current climate policies will leave more than a FIFTH of humanity exposed to dangerously hot temperatures by 2100, study warns

The prophecies never stop but nothing much ever happens

But the article is an amusing one. Very old-fashioned in its way. It examines -- wait for it -- "numbers of people left outside the ‘human climate niche’—defined as the historically highly conserved distribution of relative human population density with respect to mean annual temperature. We show that climate change has already put ~9% of people (>600 million) outside this niche." --

Fortunately, as a retired academic I can understand academic gobbledegook. More simply put: Heat is bad for you

It can even be regarded as racist to claim that climate has any effect on human beings but they are gaily doing just that. They imply that the tropics are lightly populated because heat is distressing and global warming will put more people into distressingly hot situations.

As someone who grew up in the tropics, I completely reject that. I loved my home in Far North Queensland and dream of going back there. Warmth is comforting and relaxing. You drink a lot of cold beer there but that is pretty good. It is cold that is threatening.

So why are the tropics lightly populated? I know why but dare not say it. Let me simply point out that most of the lightly populated tropical areas are in Africa

Current climate policies will leave more than a fifth of humanity exposed to dangerously hot temperatures by 2100, a study has warned.

Led by scientists at the University of Exeter, the study found that the legally binding measures currently in place will result in global warming of 4.9F (2.7C) by the end of the century.

This means two billion people - around 22 per cent of the projected end-of-century population - will be exposed to dangerous heat, with average temperatures of 84.2F (29C) or more.

At these high temperatures, water resources could become strained, mortality could increase, economic productivity could decrease, animals and crops could no longer flourish, and large numbers of people may migrate.

Globally, there are 60million people already exposed to this heat.

However, the researchers suggest there is 'huge potential' for decisive climate policy to limit the human costs of climate change.

They say the forecasts show that limiting global warming to 2.7F (1.5C), in line with the Paris Agreement, would mean five times fewer people are exposed to extreme heat.

The study, which was in association with scientists from the Earth Commission and Nanjing University in China, also found that the lifetime emissions of 3.5 average global citizens today would expose one future person to the dangerous conditions.

And in the US, this was even more concerning, as it was found just 1.2 US citizens' emissions would have the same result. This means that for almost every average person in America, their individual contribution to climate change over their lifetime could result in another person living in dangerous heat in the future.
