There's a reason you think it's getting colder. It is.

I've gone looking for the Big Green response to Lorne Gunter's article titled "Thirty years of warmer temperatures go poof" showing that temperatures are back to where they were in 1979 but all I've found are the odd comment attacking Gunter for being a conservative.

That's the way of things in Camp Climate - attack the person, obfuscate the science, start at low temperature points to show a positive trend...
In early September, I began noticing a string of news stories about scientists rejecting the orthodoxy on global warming. Actually, it was more like a string of guest columns and long letters to the editor since it is hard for skeptical scientists to get published in the cabal of climate journals now controlled by the Great Sanhedrin of the environmental movement.

Still, the number of climate change skeptics is growing rapidly. Because a funny thing is happening to global temperatures -- they're going down, not up.



On the same day (Sept. 5) that areas of southern Brazil were recording one of their latest winter snowfalls ever and entering what turned out to be their coldest September in a century, Brazilian meteorologist Eugenio Hackbart explained that extreme cold or snowfall events in his country have always been tied to "a negative PDO" or Pacific Decadal Oscillation. Positive PDOs -- El Ninos -- produce above-average temperatures in South America while negative ones -- La Ninas -- produce below average ones.

Dr. Hackbart also pointed out that periods of solar inactivity known as "solar minimums" magnify cold spells on his continent. So, given that August was the first month since 1913 in which no sunspot activity was recorded -- none -- and during which solar winds were at a 50-year low, he was not surprised that Brazilians were suffering (for them) a brutal cold snap. "This is no coincidence," he said as he scoffed at the notion that manmade carbon emissions had more impact than the sun and oceans on global climate.

Also in September, American Craig Loehle, a scientist who conducts computer modelling on global climate change, confirmed his earlier findings that the so-called Medieval Warm Period (MWP) of about 1,000 years ago did in fact exist and was even warmer than 20th-century temperatures.

Prior to the past decade of climate hysteria and Kyoto hype, the MWP was a given in the scientific community. Several hundred studies of tree rings, lake and ocean floor sediment, ice cores and early written records of weather -- even harvest totals and censuses --confirmed that the period from 800 AD to 1300 AD was unusually warm, particularly in Northern Europe.

But in order to prove the climate scaremongers' claim that 20th-century warming had been dangerous and unprecedented -- a result of human, not natural factors -- the MWP had to be made to disappear. So studies such as Michael Mann's "hockey stick," in which there is no MWP and global temperatures rise gradually until they jump up in the industrial age, have been adopted by the UN as proof that recent climate change necessitates a reordering of human economies and societies.

Dr. Loehle's work helps end this deception.

Don Easterbrook, a geologist at Western Washington University, says, "It's practically a slam dunk that we are in for about 30 years of global cooling," as the sun enters a particularly inactive phase. His examination of warming and cooling trends over the past four centuries shows an "almost exact correlation" between climate fluctuations and solar energy received on Earth, while showing almost "no correlation at all with CO2."

An analytical chemist who works in spectroscopy and atmospheric sensing, Michael J. Myers of Hilton Head, S. C., declared, "Man-made global warming is junk science," explaining that worldwide manmade CO2 emission each year "equals about 0.0168% of the atmosphere's CO2 concentration ... This results in a 0.00064% increase in the absorption of the sun's radiation. This is an insignificantly small number."

Other international scientists have called the manmade warming theory a "hoax," a "fraud" and simply "not credible."

While not stooping to such name-calling, weather-satellite scientists David Douglass of the University of Rochester and John Christy of the University of Alabama at Huntsville nonetheless dealt the True Believers a devastating blow last month.

For nearly 30 years, Professor Christy has been in charge of NASA's eight weather satellites that take more than 300,000 temperature readings daily around the globe. In a paper co-written with Dr. Douglass, he concludes that while manmade emissions may be having a slight impact, "variations in global temperatures since 1978 ... cannot be attributed to carbon dioxide."

Moreover, while the chart below was not produced by Douglass and Christy, it was produced using their data and it clearly shows that in the past four years -- the period corresponding to reduced solar activity -- all of the rise in global temperatures since 1979 has disappeared.

It may be that more global warming doubters are surfacing because there just isn't any global warming.
I'm sitting here in a much colder than normal Canberra and reading that New South Wales is suffering from an unseasonal cold snap.
RECORD cold temperatures have brought snow to the Blue Mountains and southern tablelands in NSW and wet and windy weather to the state's coast.

Temperatures dipped to three degrees celsius near Blackheath, west of Sydney, early this morning but wind gusts brought the mercury down further to minus two degrees and pockets of snow fell in Leura and west of Katoomba at Oberon.

The Bureau of Metrology (BoM) said snow was also reported in the southern tablelands at Cooma and in Bombala, near the Victorian border.

An unseasonal cold front from the southeast extends to just beyond the ranges and is moving north.

Thunderstorms and wind gusts of up to 70km/h have brought rain to the eastern part of the state and abnormally cold conditions to most of NSW.

BoM forecaster Jane Golding said average temperatures in the Blue Mountains for October ranged from seven to 18 degrees.

In Sydney today, the temperature is forecast to be 15 degrees, an October temperature which has only been seen twice in the past 14 years, Ms Golding said.
How does that happen when CO2 is meant to be forcing temperatures up?

The world is facing a financial crisis, temperatures are going nowhere but down and yet our government continues to push its lemming-like emissions trading scheme.

a funny thing is happening to global temperatures -- they're going down, not up. - are you blind? Look at the graph. The most recent point is higher than the one before it. So, global temperatures are going up, not down.

fudgie,

If I make the statement at 11AM that temperatures are going up for the day then I'd be right.

At 6PM if I said they were going down then I'd be right, also.

And how is that relevant to a graph plotting temperature anomalies?

...it's not.
