US heat dome Two-thirds of North America is at risk of energy shortfalls this summer, particularly during periods of extreme demand, according to a report from the North American Electric Reliability Corporation.
Meanwhile, 108 million Americans are under heat alerts as unforgiving temperatures bake much of the Lower 48. In addition to the Southwest, where temperatures could climb as high as 130 degrees, the nation’s three most populous states — California, Texas and Florida — are facing triple-digit temperatures. The magnitude and duration of the heat is setting records.
Southern Europe isn't doing any better.
