According to studies by scientists from China, the USA and Europe, by 2070 up to 3 billion of the projected world population of around 9 billion could be exposed to temperatures comparable to those of the hottest regions of the Sahara.
However, a rapid reduction in greenhouse gas emissions could cut the number of people exposed to such hot conditions in half.
The report highlights how the majority of people live in a very narrow mean annual temperature band of 11C-15C (52F-59F). The researchers found that, despite all the innovations and migrations, most people had lived under these climatic conditions for several thousand years.
Many people believe that this is scaremongering but it would appear as though the world’s leading politicians are behind it.
