Billions at Risk of Living in Uninhabitable Conditions Due to Global Temperature Rise

A new study published in the journal Nature Sustainability warns that if global warming continues unchecked, billions of people will be pushed outside the "climate niche," where humans can flourish, and exposed to dangerously hot conditions. By 2030, around two billion people will be outside the climate niche, facing average temperatures of 29 degrees Celsius or higher, with around 3.7 billion living outside the niche by 2090. Living outside the niche could lead to increased mortality rates, decreased crop yields, and increased conflict and the spread of disease. Experts say there is still time to slow the pace of global warming by moving away from burning oil, coal, and gas and toward clean energy, but the window is closing.
