WORST SUMMER EVER? NEW ANALYSIS OF 2010 SUMMER HEAT TO HIGHLIGHT LITTLE-DISCUSSED “DARK SIDE OF CLIMATE CHANGE”: RECORD NIGHT-TIME TEMPERATURES IN U.S.
New Focus on Sweltering Highs in Night-Time Temperatures to Outline Risks to Human Health, Environment; Record Night-Time Highs Seen in More than Three Dozen States: AL, AZ, AR, CT, DE, FL, GA, IL, IN, IA, KS, KY, LA, ME, MD, MA, MI, MN, MS, MO, NH, NJ, NM, NY, NC, ND, OH, OK, PA, RI, SC, SD, TN, TX, VA, WV, and WI.
WASHINGTON, D.C./NATURAL RESOURCES DEFENSE COUNCIL – September 15, 2010 (Investorideas.com renewable energy/green newswire) – While it is common knowledge that the summer of 2010 posted record-high temperatures across the United States, almost no attention has been paid so far to the equally disturbing trend of pervasive record high night-time temperatures where evening cooling did not occur this summer, according to a new analysis to be released at 11 a.m. EDT Thursday (September 16, 2010) by Natural Resources Defense Council (NRDC).
More than three dozen states (and a correspondingly significant share of the nation’s population) contain weather stations that recorded record high night-time temperatures, the “dark side of climate change” under which temperatures do not cool off overnight. The NRDC analysis breaks out the number of U.S. counties and their respective population that experienced these record night-time temperatures.
The 37 states with record high night-time temperatures highlighted in the report are: Alabama, Arizona, Arkansas, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Virginia, West Virginia, and Wisconsin.
News event speakers will be:
- Dan Lashof, director, Climate Center, Natural Resources Defense Council; and
- Kim Knowlton, senior scientist, Health Program, Natural Resources Defense Council.
The NRDC analysis outlines the danger of heat deaths and other impacts that are linked to the growing problem of summer temperatures that do not drop overnight.

Note that the concrete surface is around 22-24°C, while the grassy areas are between 12-19°C. This was shortly after a rain, about 2 hours before sunset. The rain did nearly nothing to cool down the concrete.
