Climate change truth wallops USA hard
On 2012 June 28 in the USA, 205 high temperature records were broken and 74 were tied, according to data from the National Oceanic and Atmospheric Administration’s (NOAA) National Climatic Data Center (NCDC).
An intense heat wave broke records in more than a dozen states on Friday, and spawned one of the most damaging severe thunderstorm events seen in years. At least 3 million Americans, mainly in areas from Indiana Southeast to Virginia, were facing the prospect of another day of triple-digit heat heat.
From Atlanta to Baltimore, temperatures approached or exceeded triple digits. Atlanta set a record with a high of 105 degrees, while the temperature hit 99 at Ronald Reagan Washington National Airport just outside the nation’s capital.
There were numerous daily, monthly, and all-time record high temperatures established on Friday. In total, there were 276 record daily high temperatures set or tied on Friday, along with 70 record warm overnight low temperature records. There were also 96 monthly record high temperatures, and 37 all-time high temperature records set or tied.
For the year-to-date, warm temperature records are outpacing cold temperature records by a ration of 7-to-1. Since January 1 there have been 21,402 daily high temperature records set, compared to just 3,338 daily records for cold high temperatures, according to a database maintained by the National Climatic Data Center.
In a long-term trend that demonstrates the effects of a warming climate, daily record-high temperatures have recently been outpacing daily record-lows by an average of 2-to-1, and this imbalance is expected to grow as the climate continues to warm. According to a 2009 study, if the climate were not warming, this ratio would be expected to be even.
