Climate change is making heat waves linger for longer stretches of time, exacerbating the effects of extreme temperatures. When heat waves swept across large parts of the planet last summer, in many places the oppressive temperatures loitered for days or weeks at a time. As climate change warms the planet, heat waves are increasingly moving sluggishly and lasting longer, according to a study published recently. Each decade between 1979 and 2020, the rate at which heat waves travel, pushed along by air circulation, slowed by about 5 miles per day, the study found. Heat waves also now last about four days longer on average.
