well the new ice age is on the way.
Researchers with the Russian Academy of Sciences warned Wednesday that the Earth could be headed for a 60-year cooldown, the news agency Interfax reported.
Scientists based at the academy's Pulkovskaya Observatory in St Petersburg, Russia, said they expected a gradual decrease in global temperatures in 2012-15, followed by a more dramatic, 60-year period of cold to come in 2055-60.
Khabibullo Abdusamatov, chief researcher at the observatory, said the predictions were based on solar cycles, and that after the 60-year glimpse of the Ice Ages warmer weather could be expected.
Abdusamatov did not say how much cooler the Earth would get.
Little is known about long-term weather patterns. Evidence that the globe's surface temperature has warmed by about a half-degree Celsius in recent years has livened debate about whether a buildup of greenhouse gases is to blame for global warming, or if it is part of a naturally occurring cycle.
The United States' National Academy of Sciences has reported it cannot say with any certainty what has caused the current warming. Scientists have noted a warming of the surface temperature appeared to have occurred between the 1890s and 1940s, and that a 30-year period of cooler temperatures followed.
What is clear is that a little warming goes a long way: During the most recent ice age, which ended 10,000 years ago, much of North America, including New York, is thought to have been covered in glaciers.
The global surface temperature then was some 4 to 5 degrees colder than it currently is.
The Russian academy, meanwhile, did not use its predictions to weigh in on whether greenhouse gases will lead to catastrophic global warming.
Abdusamatov, the researcher, did add that his colleagues had prepared instruments to monitor changes in the Earth's temperature from outer space.
The technology is hoped to be installed on the International Space Station in 2008, with observations to begin in 2009.
"Such a highly accurate apparatus does not yet exist anywhere in the world," Abdusamatov said without specifying what exactly the apparatus was.
He said the Russian government had contributed 20 million rubles (7.5 million US dollars) to cover half the project's costs. The scientists, Abdusamatov added, are hoping to find sponsors to provide the other half.
