New research shows that billions of people could be forced out of the “human climate niche” as the planet warms.
The Guardian reports that current climate commitments, which see global temperatures rise by 2.7C above pre-industrial levels, could push 2 billion people out of their “climate niche”.
Limiting warming to 1.5 °C would limit the number of people who would be pushed out of the climate niche by 80%, the paper said.
The newspaper notes that the climatic niche is defined by average annual temperatures above 29C. He continues: “The analysis is the first of its kind and is able to treat every citizen equally, unlike previous economic assessments of the damage from the climate crisis, which targeted the wealthy.”
The Times reports that on current emissions trajectories, more than one billion people could be forced to migrate.
The Press Association adds that “under worst-case scenarios of global warming of 3.6C or even 4.4C, half the worhttps://europeantimes.news/international/ld’s population could be left outside the climate niche, posing an ‘existential risk’.”
The Independent claims that “for every 0.1C warming above current levels, an extra 140 million people will be exposed to dangerous heat conditions”.
The South China Morning Post notes that in India and Nigeria, the population will be most exposed to dangerous heat.
Forbes quoted study author Tim Lennon as saying: “It’s easy to see how uncontrollable temperature increases will lead to extraordinary movements across borders.”
