Last year's summer melt had been so fierce that climate scientists warned that the warmed seas gave us a 50-50 chance of an ice-free Arctic this summer.

"It's hard to see how the system may bounce back," fretted Washington University's Ignatius Rigor.

Countless headlines around the world blared this latest "proof " of global warming (which, sshhh, actually halted in 1998). The ABC and Fairfax flew reporter Marian Wilkinson up to file scary reports from an ice-breaker, declaring: "Here you can see climate change happening before your eyes."

Eco-explorer Lewis Gordon Pugh even announced he'd paddle a kayak all the way to the Pole to draw attention to this terrifying loss of ice.

But, oops. Pugh actually had to quit paddling when he found 1000km more ice in front of him than he'd expected.

Indeed, there was at least 9 per cent more Artic ice this summer than last, and the refreeze so far this autumn is so extraordinary there's a third more ice than there was this time a year ago.

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."

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."
