Don’t Believe The Washington Post Propaganda, DC Summers Are Not Getting Hotter

More fraud from Climate Central.

The temperature Thursday in Washington soared to 98 degrees, the hottest so far this summer. The heat index, which factors in humidity, registered 104 degrees.
Get used to it.
An analysis released Wednesday by Climate Central, a nonprofit science communication group based in Princeton, N.J., says these kinds of brutally hot and humid days are becoming more common.
Climate Central’s States at Risk project, featuring an interactive website, not only analyzed historical heat and humidity data to document observed trends but also, using climate models, projected how hot and humid days will evolve into the future.
All data point toward steamier times ahead.
Hot and humid days up substantially since 1970
The District is now sweltering in 95-degree heat on 7.5 more days per year than it did in 1970, Climate Central says. In 1970, D.C. averaged seven or eight 95-degree (or hotter) days in a typical year. Now the number is closer to 15. In the scorching summer of 2012, we had a record-tying 28 such days.
The nearest long running station to Washington is Laurel, in Maryland, just 17 miles away.
The USHCN whisker plot of daily maximum temperatures shows that daily temperatures are not increasing, and were actually highest in the 1930s.
It is easy to see why Climate Central used 1970 as their starting point.
As CDIAC show below, most daily summer temperature records in Maryland were set prior to 1960, while the cold 1970s is plainly evident. (Bear in mind, these daily records include ties, so the probability of a record should be the same in every decade, assuming an unchanged climate).
This carefully constructed deception is all designed to convince us that summers will become increasingly hot in the future, as the article goes on to state:
D.C.’s summer climate to resemble South Texas?
Using projections of summer warming by 2100, Climate Central says D.C.’s climate will, by then, most resemble today’s typical summer environs in Pharr, Texas — a Mexico border town. That is, it projects D.C.’s average summer high temperature to rise from roughly 87 degrees to 97 degrees.
Of course, such projections are based on climate models which assume the emissions of greenhouse gases will continue unabated through the end of the century. If the global community finds ways to cut emissions, the warming would not be this steep. Also, if the climate is less sensitive to increases in greenhouse gases than assumed by these models, the warming would be less.
But, observed data make it clear the D.C. area is on a warming trajectory.
Climate Central’s analysis documents similar trends in hundreds of metro areas across the Lower 48. “Using several measures, our findings show that most U.S. cities have already experienced large increases in extreme summer heat and absolute humidity, which together can cause serious heat-related health problems,” the analysis states.
The Washington Post article is written by Jason Samenow, their weather editor and chief meteorologist of the Capital Weather Gang. He should be ashamed of himself for publishing such blatant propaganda from the politically motivated Climate Central.
Indeed, his failure to carry out even the most basic checks on their grossly misleading analysis surely raises questions about whether he has the ability and objectivity to do his job properly.
