WASHINGTON -- When the calendar turned to 2007, the heat went on and the weather just got weirder.

January was the warmest first month on record worldwide — 1.53 degrees above normal. It was the first time since record-keeping began in 1880 that the globe's average temperature has been so far above the norm for any month of the year.

And as 2007 drew to a close, it was also shaping up to be the hottest year on record in the Northern Hemisphere.

US weather stations broke or tied 263 all-time high temperature records, according to an Associated Press analysis of US weather data. England had the warmest April in 348 years of record-keeping there, shattering the record set in 1865 by more than 1.1 degrees Fahrenheit.

It wasn't just the temperature. There were other oddball weather events. A tornado struck New York City in August, inspiring the tabloid headline: "This ain't Kansas!"

In the Middle East, an equally rare cyclone spun up in June, hitting Oman and Iran. Major U.S. lakes shrank; Atlanta had to worry about its drinking water supply. South Africa got its first significant snowfall in 25 years. And on Reunion Island, 400 miles east of Africa, nearly 155 inches of rain fell in three days — a world record for the most rain in 72 hours.

Individual weather extremes can't be attributed to global warming, scientists always say. However, "it's the run of them and the different locations" that have the mark of man-made climate change, said top European climate expert Phil Jones, director of the climate research unit at the University of East Anglia in England.

Worst of all — at least according to climate scientists — the Arctic, which serves as the world's refrigerator, dramatically warmed in 2007, shattering records for the amount of melting ice.

2007 seemed to be the year that climate change shook the thermometers, and those who warned that it was beginning to happen were suddenly honored. Former Vice President Al Gore's documentary "An Inconvenient Truth" won an Oscar and he shared the Nobel Peace Prize with the Intergovernmental Panel on Climate Change, an international group of thousands of scientists. The climate panel, organized by the United Nations, released four major reports in 2007 saying man-made global warming was incontrovertible and an urgent threat to millions of lives.
