Prof Tim Lenton at the University of Exeter, UK, who led the new research, said: “The costs of global warming are often expressed in financial terms but our study highlights the phenomenal human cost of failing to tackle the climate emergency. India is already suffering from extreme heatwaves, and a recent study found that more than a third of heat-related deaths in summer from 1991-2018 occurred as a direct result of human-caused global heating. In countries with large populations and already warm climates most people will be pushed outside the human climate niche, with India and Nigeria facing the worst changes. The analysis is the first of its kind and is able to treat every citizen equally, unlike previous economic assessments of the damage of the climate crisis, which have been skewed towards the rich. However, urgent action to lower carbon emissions and keep global temperature rise to 1.5C would cut the number of people pushed outside the climate niche by 80%, to 400 million. ![]() ![]() ![]() ![]() Up to 1 billion people could choose to migrate to cooler places, the scientists said, although those areas remaining within the climate niche would still experience more frequent heatwaves and droughts. ![]()
