Dispatches from the era of extreme heat

Record High

EDITOR’S NOTE

As carbon emissions rise, communities across the globe are dealing with increasingly severe and frequent bouts of extreme temperatures. Scientists have observed an eightfold increase in record-breaking hot months over the past decade, and at any given time, extreme heat is now affecting about one-tenth of the Earth’s land area. Some 8 million Americans were exposed to “extreme danger” temperatures last year alone, defined by the National Weather Service as a heat index of more than 125 degrees Fahrenheit. By 2053, that number is expected to rise to 107 million.

These scorching temperatures are impacting public health, drought, agriculture, infrastructure, equity, ecosystems, and much more. But there are also innovative solutions, policies, and technologies being tested to adapt to this hotter future.
