The massive floating canopy of ice that covers the Arctic Ocean receded over a nine-year period, possibly reflecting the effects of global warming, researchers said. The canopy, which at times is 70% larger than the United States, drew back about 2% between October, 1978, and August, 1987, researchers said. But scientists cautioned that they do not know enough yet to blame global warming, the expected consequence of a buildup in the atmosphere of heat-trapping gases.

Fifty-five million years ago the Arctic was a lot like Miami, with an average temperature of 74 degrees, alligator ancestors and palm trees, scientists report in the current issue of the journal Nature. Scientists had known the Arctic had warmed, but previously believed it had reached about 52 degrees. The new conclusion is based on first-of-their-kind core samples extracted from more than 1,000 feet below the Arctic Ocean floor.

Ray Sambrotto is a little out of touch. He can't be reached by phone, fax or e-mail. He won't see this year's World Series, or join the rest of the planet in enduring the final weeks of the 1996 U.S. presidential election. He'll even miss the trees bursting into red, orange and gold near his Hudson Valley home. The soft-spoken oceanographer has been thrown into one of the most isolated environments on the planet, a place a colleague calls "a sensory-deprivation tank with company." Until Nov.

A massive 19-square-mile ice shelf in Canada's northern Arctic has broken away and is floating in the Arctic Ocean, the latest sign of rapid climate change in the remote region, a team of scientists said Tuesday. They said the Markham Ice Shelf -- one of just five remaining ice shelves in the Arctic -- split away from Ellesmere Island in early August. They also said two large chunks totaling 47 square miles had broken off the nearby Serson Ice Shelf, reducing it in size by 60%. Derek Mueller, an Arctic ice shelf specialist at Trent University in Ontario, said the amount of ice lost from the shelves this summer totaled 83 square miles.

Loss of sea ice due to global warming could open new seasonal shipping lanes through the Arctic Ocean by midcentury, sharply reducing transit times and opening a Pandora's box of safety, environmental and legal issues, according to scientists. In a paper published Monday in the Proceedings of the National Academy of Sciences Plus, researchers estimated that new shipping lanes linking the Atlantic and Pacific oceans are likely to open between 2040 and 2059. The lanes would not be open year-round, however, and would likely be restricted to late summer, when ice cover is lowest.

A British explorer says he is planning the most accurate survey of the thickness of the Arctic ice to gauge the effects of global warming. The Vanco Arctic Survey will entail a 1,240-mile trek to the North Pole next year. On the way, explorers will take millions of readings of the thickness and density of the ice and snow to try to provide the clearest picture of the polar ice cap and how long it will last.

I can really relate to Haywood's piece on racism. I fairly recently made a mistake like his mistake of suggesting to his fellow jurors that a young black man's troubles with the Beverly Hills police might have been due to the color of his skin. My mistake was in suggesting to my colleagues at a principals' meeting that, perhaps, we shouldn't rely heavily on police in solving some of the problems we face in our schools. My reasoning was that in my opinion--based on my personal experiences as a black person--police officers don't always handle situations in a positive manner, especially problems involving minorities.

A Russian expedition led by a nuclear-powered icebreaker reached the North Pole on Wednesday on a mission to send two mini-submarines to the polar seabed. The expedition, which would be the first to reach the polar sea bottom 2.6 miles below the Arctic Ocean surface, is seen as part of an effort to bolster Russian claims to about 460,000 square miles of sea floor believed to hold lucrative deposits of oil and natural gas.

A russian expedition reached the North Pole on Wednesday and sent two men in submarines 2.65 miles below the Arctic Ocean to explore the seabed -- and, not incidentally, to plant a titanium capsule containing the red, white and blue Russian flag. The explorers want bragging rights for a journey they compare to "taking the first step on the moon," but they are also pressing Russia's claim to a vast swath of the Arctic Ocean.
