Records shattered as summer heat hits Southwest in March

Scientists say the March heat dome added 4.7–7.2°F to temperatures, making the record-breaking heat wave virtually impossible without human-caused climate change.

  • A historic heat wave shattered March records across the U.S. Southwest on Thursday and Friday, with Martinez Lake, Arizona, reaching 110°F—the highest March temperature ever recorded in the United States.
  • Human-Caused climate change made the extreme heat "virtually impossible," according to a Friday report by World Weather Attribution; warming from burning coal, oil, and natural gas added up to 7.2 degrees Fahrenheit to temperatures.
  • University of Victoria climate scientist Andrew Weaver stated extremes are pushing "beyond the bounds we once thought possible," as the Southwest faces deadly heat months ahead of normal seasonal timing.
  • Authorities in Phoenix restricted access to popular hiking trails through Sunday due to dangerous heat conditions, while the National Weather Service reported temperatures running up to 30 degrees Fahrenheit above average in parts of the region.
  • Data from the National Oceanic and Atmospheric Administration shows the United States is breaking 77% more hot weather records now than in the 1970s, with experts warning such events are becoming recurring features of a warming world.
