If Philadelphia has a run of abnormally hot weather this summer, it will be considered less unusual than it would have been a year ago. Thats because normal now has a new definition. A set of updated national climate averages due to be released this week shows that average summer temperatures in the city are nearly 2°F warmer than the benchmarks meteorologists have been citing for the past decade.
The updates come from the National Oceanic and Atmospheric Administration (NOAA), which will impliment its new 30-year Climate Normals on July 1. When weather forecasters use terms like above normal or below normal, theyre referring to average temperatures and precipitation figures compiled from daily, monthly and yearly readings at thousands of locations across the country during the previous three decades. The normals that are about to expire are based on conditions from 19712000; the new ones start in 1981 and unlike their predecessors, they include the first decade of the 21st century, which was among the hottest on record for the country (and was the hottest on record globally). They also exclude the 1970s, which was a particularly chilly decade in many areas. As a result, the new normal temperatures for Philadelphia and the rest of the nation are higher than the previous set.

What we think of as really hot days just arent as unusual as they once were, says Gary Szatkowski, chief meteorologist at the National Weather Services Mount Holly, N.J. forecast office, which serves the Philadelphia metro area. Were having more of these really hot days, and that is now reflected by these new normals.

Different parts of the government saying different things.
I guess that is why, here in Central Washington State, we are two weeks behind in our norma cherry harvest.
Western NY has had a long cold Winter, and here it is end of June and not warm enough to swim in a pool that gets 80% sun.
Warming is a hoax, It’s to sell carbon credits, fund Universities and control our lives.
Total BS
Even after being caught red handed w/ mfg lies, They keep pushing the lies
NH just seems cold, colder and coldest. Live Freeze or Die.
Yawn...whatever.
This is a result of a couple different factors. First, the 1970s were indeed rather cool, and the 2000s were warmer (than the 70s). Second, the urban heat island effect is a part of this. Many measuring stations were in rural areas in the 70s but by the 2000s those areas were urbanized. Urban areas generate heat, creating a heat island. Some stations were outside the artificially warm areas in the 70s but are very much in them now.
The fruitcakes will be stirred up again. Ug.
We currently have available to us global data obtained by satellites.
I guess they don’t trust the readings of their own satellites, which show temperatures in decline since 1997.

yep. they’d rather use poorly sited urban readings, that a NASA report says can add up to EIGHT degrees compared to a nearby rural station.
(which is why the also eliminated over 1000 rural stations from the grid. ...anything, to “hide the decline”.)
...the greatest, most costly hoax in human history.
wow. great find!!!
i went to your link in #18, thinking it would be a denier site like greeniewatch (my favorite).
but that is much more mainstream. wonderful!
the cracks are opening faster than i thought!
...also, Steely Tom has a great link:
http://www.freerepublic.com/focus/f-news/2740366/posts
it shows that the OBAMA administration KNOWS
it is getting colder, at the same time the NOAA and NASA are hyping warmer.
i wish this would get as much attention as gunwalker.
it is a LOT bigger and more costly, affecting EVERY American!
