"What the nation is now seeing is “a super-heated spike on top of a decades long warming trend,” said Derek Arndt, head of climate monitoring at the National Climatic Data Center in Asheville, N.C.
The U.S. set 107 new temperature records on Monday and in the past week has set 782 of them, which are large numbers but hard to put in context because the data center has only been tracking the number of daily records broken for little more than a year, Arndt said.
But what’s truly impressive, Arndt said, is that in the past three days in Colorado and Kansas, nine sites have set records regardless of the date. Usually hottest-ever marks are set in the scorching months of July and August."
