  • 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 on Friday ...
  • "This really has strong impacts on public health," said Wei Zhang, a climate scientist at Utah State University and one of the authors of the study, which appeared in the journal Science Advances ...
  • Rachel White, an atmospheric scientist at the University of British Columbia who wasn't involved in the paper, said she had been waiting to see research like this. ...

      • If heat waves become more frequent, more intense, last longer and cover a greater area, he said, "that really increases the concern we have for their impacts.". . Dr. Zhang is especially concerned about cities, which are often hotter than their surrounding areas because of the urban heat island effect ...
