Researchers from Hawaii who published a study in the journal Nature have warned that due to man-made climate change, major cities such as London, Paris, and New York could be uninhabitable within 45 years.
They added that even if we utilise all resources to stop our current carbon emission, the changes are irrevocable and can only be postponed.
Study leader Camilo Mora told NBC news: “We are used to the climate that we live in. With this climate change, what is going to happen is we're going to be moving outside this comfort zone.
“It is going to be uncomfortable for us as humans and it will be very uncomfortable for species as well.”
He added: “Countries first impacted by unprecedented climate change are the ones with the least economic capacity to respond. Ironically, these are the countries that are least responsible for climate change in the first place.
“By expanding our understanding of climate change, our paper reveals new consequences for biodiversity and highlights the urgency to take action now.”
