The Washington Post considers the heat wave and derecho thunderstorm that hit the Washington, D.C. area on Friday and wonders what role “manmade climate warming” might have played.
“As the intensity of the heat wave, without reservation, was a key factor in the destructiveness of this derecho event – it raises the question about the possible role of manmade climate warming (from elevated greenhouse concentrations),” the Post writes (emphasis added). “It’s a complicated, controversial question, but one that scientists will surely grapple with in case studies of this rare, extraordinary event.”
The Post does not provide evidence for its assertion, but the paper does detail the weather conditions:
…
On Friday, a historic, record-setting heat wave covered a sprawling region from the Midwest to the Southeast. … Here in Washington, D.C., the mercury climbed to an astonishing 104 degrees (breaking the previous record set in 1874 and 2011 by two degrees),our hottest June day in 142 years of records. …
This derecho event is likely to go down as not only one of the worst on record in Washington, D.C. but also along its entire path stretching back to northern Indiana.
The Associated Press has more details on the destruction:
Power officials said the outages wouldn’t be repaired for several days to a week, likening the damage to a serious hurricane. Emergencies were declared in Maryland, West Virginia, Ohio, the District of Columbia and Virginia, where Gov. Bob McDonnell said the state had its largest non-hurricane outage in history, as more storms threatened. “This is a very dangerous situation,” the governor said.
