The U.N. Climate Panel said last year that global warming was "unequivocal." It said temperatures rose by 0.74 degrees Celsius (1.3 Fahrenheit) in the 20th century and could rise by a "best guess" of another 1.8 to 4.0C (3.2 to 7.2F) by 2100.

And they are at it again.
Even though global warming has stalled out for almost ten years, and 2008 began with cooling in many areas.
I agree with the U. N. Climate Panel's first sentence: global warming is unequivocal. And it is entirely natural.
Unlike Al Gore and the U. N. Climate Panel, who have to deny the undeniably warmer Medieval Warm Period, and totally ignore the even warmer Holocene Optimum in order to further their messianic belief that global warming is man made, we skeptics of man-caused global warming trumpet the fact that there is global warming, that it is expected, and that it is natural.
In support of our position we have hundreds of thousands of years of records of prior dramatic climate changes. We can point to voluminous records that show warming periods are soon followed by increased atmospheric carbon dioxide, again what would be expected since oceans are the primary depository for carbon dioxide, and lose carbon dioxide to the atmosphere as they warm.
However, at the moment the religion of man-caused global warming has hit a dog leg in their dogma. Since 1998 global temperatures have not been rising. In fact, in may locales there has been some cooling.
Computer models don’t show this scenario, where atmospheric CO2 is increasing steadily, and temperature is not.
Rajendra Pachauri, the head of the U.N. Panel that shared the 2007 Nobel Peace Prize with former U.S. Vice President Al Gore, said he would look into the apparent temperature plateau so far this century.
While Mr. Pachauri is doing that, he should also look at the climate record since 1900. By doing that he would notice that most of the increase in global temperatures since 1900 occurred in the first half of the century, and that six of the ten warmest years in the United States occurred over fifty years ago.
Over fifty years ago was before atmospheric CO2 caused by mankind’s industrial activities increased significantly.
Mr. Pachauri would also notice that, during the first thirty years of greatly increased atmospheric CO2 (1945-1975), the Earth experienced global cooling.
Although the twin anomalies of a greater increase in global warming in the first half of the 20th Century and global cooling for most of the second half don’t fit the man-caused global warming constructs, these anomalies do fit very well with fluctuations in solar activity.
Not surprisingly, the Medieval Warm Period, Little Ice Age, Holocene Optimum, Roman Warm Period, and Dark Ages Cool Period all track precisely with solar variation.
For Al Gore and the U. N. Climate Panel, inconvenient truths indeed.
