Since the mid-19th century, the mean global temperature has increased by 0.7 degrees Celsius. This slight warming is not unusual, and lies well within the range of natural variation. Carbon dioxide continues to build in the atmosphere, but the mean planetary temperature hasn't increased significantly for nearly nine years. Antarctica is getting colder. Neither the intensity nor the frequency of hurricanes has increased. The 2007 season was the third-quietest since 1966. In 2006 not a single hurricane made landfall in the U.S.
South America this year experienced one of its coldest winters in decades. In Buenos Aires, snow fell for the first time since the year 1918. Dozens of homeless people died from exposure. In Peru, 200 people died from the cold and thousands more became infected with respiratory diseases. Crops failed, livestock perished, and the Peruvian government declared a state of emergency.Unexpected bitter cold swept the entire Southern Hemisphere in 2007. Johannesburg, South Africa, had the first significant snowfall in 26 years. Australia experienced the coldest June ever. In northeastern Australia, the city of Townsville underwent the longest period of continuously cold weather since 1941. In New Zealand, the weather turned so cold that vineyards were endangered.

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.
Oklahoma, Kansas and Missouri are just emerging from a destructive ice storm that left at least 36 people dead and a million without electric power. People worldwide are being reminded of what used to be common sense: Cold temperatures are inimical to human welfare and warm weather is beneficial. Left in the dark and cold, Oklahomans rushed out to buy electric generators powered by gasoline, not solar cells. No one seemed particularly concerned about the welfare of polar bears, penguins or walruses. Fossil fuels don't seem so awful when you're in the cold and dark.
No, they don't.
