Just look at Alaska, which experienced all-time record heat in July, topping out at 90 degrees Fahrenheit. Dozens of other cities are in the throes of a heat wave this week, which forecasters have warned will be “prolonged, dangerous, and potentially deadly.”
But how much will temperatures in US cities change by 2050? By then, scientists say average global warming since preindustrial levels could be about twice what it is in 2018 — and much more obvious and disruptive. It’s a world you’ll (probably) be living in. And it’s the one we’re definitely handing off to the next generation.
