In 50 Years Many Parts of the World Could be Too Hot for Humans

"Unless steps are taken to check global warming, up to 3 billion people will find themselves in areas too warm for human comfort, a new study finds."

"By 2070, the world's habitable climate zone will shift so much that billions of people will be pushed past human comfort levels.

A new study published Monday in the Proceedings of the National Academy of Sciences shows  a "surprisingly narrow" human climate niche—between 52 degrees Fahrenheit to 59 degrees Fahrenheit. And it will shift geographically more in the next 50 years than any time during the past 6,000 years. As a result, up to 3 billion people are "likely to live under climate conditions that are warmer than conditions deemed suitable for human life to flourish," the international team of researchers wrote.

Los Angeles and Paris will bake in fiery desert temperatures, and the world's most populous cities in Asia and Africa will have deadly heat waves every year."
