Climate change: Millions may migrate due to extreme temperature
Scientists have warned that more than a fifth of people on Earth will live in extreme temperatures by 2100, with more than a billion forced to migrate if the planet continues on its present climate change trajectory.
A team from the University of Exeter and experts from Europe, China and the US found that billions of people face living in a climate outside the boundaries that have allowed humanity to flourish over millennia.
