The summer of 2010 was the hottest in New York’s history, which proves global warming.
The summer of 2009 was the coldest in Chicago’s history, which also proves global cooling. Or perhaps it was the “Urban Cold Island” effect.
Heat is climate, but cold is just weather.
OOOOO a cold summer. How about looking at overall trends. You might see that it is warming. Don’t do big oils bidding. Educate yourself.
OOH – Big Oil!!
What filling station do you top up at Hal?

“Heat is climate, but cold is just weather” is generally trotted out as a free pass for “hey, it’s cold, where’s that global warming?” Oddly, if one watches forums where GW is discussed, there are almost always more ‘cold=weather’ excuse posts than the opposite, though both sides are guilty to some extent.
Climatologists know that individual weather events are not statistical trends. So does anyone who studies the issue honestly. Neither side’s argument benefits from single weather events.
Dr. Hansen is more than happy to trot out a 12-month El Nino average temperature as proof of global warming, and also is careful to dismiss La Nina cooling as just weather.
“Proof?”, he said? I don’t believe you. Not to be overly rude, but I don’t think that happened. Those are merely superimposed signatures, same as the PDO, insolation, particulates, etc. In my readings 30 years is widely seen as an appropriate statistical climate series.
You could show me the quote if you like. Or not. It’s casual.
Like the climatologists at NRDC? http://yubanet.com/enviro/2010-Summer-is-Preview-of-Future-Climate-Destruction.php
Yea, both sides are guilty, but only one side uses it to scare people into thinking we are all doomed. Hard to compare as balanced the used of the term weather on one side, and climate destruction on the other.
“Fall may be here but we should not forget the Summer of 2010 as a harbinger of things to come,” said Dan Lashof, NRDC’s climate center director. “And this should come as no surprise to anyone because scientists have been warning us for years to expect this kind of climate destruction as a result of carbon pollution.”
Mmm, I wouldn’t let one suit’s summary scare you. The link to the actual report is in the article:

Not much doom to be found.
Ensemble models for hurricane tracking are a good example.
The “climatological” model (ie what the average over all records shows) is invariably way off from “current” models (ie fed with todays measurements and fine tuned based on +/- assumptions about the actual value of the varous equation parameters) that each investigate various “versions” of the factors most likely to affect the track.
Just seeing how the model “guesstimates” pan out is an education in itself.
An example of the above:
