Global warming to cause a U.S. "Extreme Heat Belt," study warns
A new study reveals the emergence of an “extreme heat belt” from Texas to Illinois, where the heat index could reach 125°F at least one day a year by 2053.
The big picture: In just 30 years, climate change will cause the Lower 48 states to be a far hotter and more precarious place to be during the summer.

What began as a theory in the 1890s — that industrial emissions of carbon dioxide could increase global temperatures — had progressed to a scientific fact a century later. Scientists across a range of disciplines are studying the impact of the still-growing concentration of carbon dioxide and other so-called “greenhouse gases” in the atmosphere as they call for industrial and governmental policies to slow, then halt, the warming of the planet.
