"There is no proof that the current warming is caused by the rise of greenhouse gases from human activity. Ice core records from the past 650,000 years show that temperature increases have preceded—not resulted from—increases in CO₂ by hundreds of years, suggesting that the warming of the oceans is an important source of the rise in atmospheric CO₂. As the dominant greenhouse gas, water vapour is far, far more important than CO₂. Dire predictions of future warming are based almost entirely on computer climate models, yet these models do not accurately understand the role or water vapor—and, in any case, water vapor is not within our control. Plus, computer models cannot account for the observed cooling of much of the past century (1940–75), nor for the observed patterns of warming—what we call the “fingerprints.” For example, the Antarctic is cooling while models predict warming. And where the models call for the middle atmosphere to warm faster than the surface, the observations show the exact opposite.

The best evidence supporting natural causes of temperature fluctuations are the changes in cloudiness, which correspond strongly with regular variations in solar activity. The current warming is likely part of a natural cycle of climate warming and cooling that’s been traced back almost a million years. It accounts for the Medieval Warm Period around 1100 A.D., when the Vikings settled Greenland and grew crops, and the Little Ice Age, from about 1400 to 1850 A.D., which brought severe winters and cold summers to Europe, with failed harvests, starvation, disease, and general misery. Attempts have been made to claim that the current warming is “unusual” using spurious analysis of tree rings and other proxy data. Advocates have tried to deny the existence of these historic climate swings and claim that the current warming is "unusual" by using spurious analysis of tree rings and other proxy data, resulting in the famous “hockey–stick” temperature graph. The hockey-stick graph has now been thoroughly discredited."

Recent weeks have seen the return of unusually cold conditions to the Northern Hemisphere. On Dec. 7, St. Cloud, Minn., set a new record low of minus 15 degrees Fahrenheit. On the same date, record low temperatures were also recorded in Pennsylvania and Ohio.

Extreme cold weather is occurring worldwide. On Dec. 4, in Seoul, Korea, the temperature was a record minus 5 degrees Celsius. Nov. 24, in Meacham, Ore., the minimum temperature was 12 degrees Fahrenheit colder than the previous record low set in 1952. The Canadian government warns that this winter is likely to be the coldest in 15 years.

DENVER (AP) - Bitterly cold air poured southward across the nation's midsection Wednesday, dropping temperatures to record lows from Montana to Illinois.

The mercury dived to a record 45 below at West Yellowstone, Mont., the frequently cold spot at the west entrance to Yellowstone National Park, the National Weather Service said. The old record for Dec. 7 was 39 below, set in 1927.

The cold even extended south to the Texas Panhandle, where Lubbock shivered at a record low 6 above zero, the weather service said.

The body of a homeless man was found huddled next to a fence in Denver, where the temperature hit 11 below Wednesday, and authorities were trying to determine if he froze to death. He apparently had shed his jacket in a phenomenon called "paradoxical undressing," where victims of hypothermia become disoriented and hallucinate, deputy coroner Amy Martin said.

The Denver Rescue Mission opened all available space for the homeless.

The coldest spot in Colorado early Wednesday was Hohnholz Ranch, 50 miles northwest of Fort Collins, which bottomed out at 37 below zero, the weather service said.

In Gunnison, Alec Solimeo tended bar at the Timbers Sports Bar & Grill wearing a couple layers of clothing Tuesday as a faulty heater let the inside temperature drop to 42 degrees. The outside temperature fell to 12 below early Wednesday, the weather service said.

"I'm keeping these travelers happy," Solimeo said, adding that his regular customers apparently stayed home. "They're playing pool, drinking some Irish coffee and doing some singing."

Temperatures read like baseball scores in northeastern New Mexico—zero at Las Vegas and 1 at Raton. "I'm sitting here in my office and it's freezing and we've got the heat on full blast," said Bill Cox, owner of the Hillcrest Restaurant in Las Vegas.

The cold follows a blizzard that blasted much of the Plains on Nov. 27-28, shutting down hundreds of miles of major highways across a half-dozen states and piling up snowdrifts 8 feet high in South Dakota.

Just two of the 157 South Dakota towns that had power problems after that storm snapped power lines were still without electricity Wednesday, but more than 3,600 rural customers were still blacked out, said Tom Dravland, state public safety secretary. Lows across the eastern part of the state dipped to as much as 20 below.

A winter storm warning was issued Wednesday in and around the Dallas- Fort Worth area, where the temperature fell from the low 40s before sunrise to the upper 20s by the end of the morning rush hour. Freezing rain and sleet fell Wednesday and up to 2 inches of snow was predicted by Thursday morning.

Elsewhere Wednesday, the weather service said record lows for the date included 28 below zero at Drummond, Mont., where the date's previous record was 21 below in 1971; 26 below at Seeley Lake, Mont.; 25 below at Laramie, Wyo., tying a 1978 reading; 17 below at Alliance, Neb.; 19 below at Cedar Rapids, Iowa; and 3 below at Lincoln, Ill.
