The theory of global warming proposes that man's activities are causing the Earth to heat up, but there is compelling scientific evidence that does not support this conclusion.   Very few people have heard of the Larsen B ice shelf. For thousands of years in the Antarctic, the place was a desolate frozen wasteland, crisscrossed by crevasses and swept by powerful ice and snowstorms. Beginning in 2002, satellite imagery began to show instability in the Larsen B ice shelf. According to research published by the journal Nature, much of the more than 4,600 square mile ice shelf collapsed. Since then, icebergs...

ST. JOHN'S, NFLD. - Canadian scientists have found some intriguing similarities between grooves caused by icebergs and marks on the surface of the Red Planet. Chris Woodworth-Lynas normally sets his sights on the ocean floor, studying how icebergs scour the seabed. Oil and gas companies need the information to lay down pipelines. After work, Woodworth-Lynas applied his skills to Mars. "There has been theories that there was perhaps an ocean or series of oceans in the north polar regions," said Woodworth-Lynas. When Woodworth-Lynas downloaded NASA's orbital photos of Mars from 1997, he was able to resolve features. On their own...

Source: Pacific Northwest National Laboratory Date: 2003-11-04 Sky-high Icebergs Carried Boulders From The Rockies To In South-central Washington Seattle -- Geologists have uncovered a scene in the Pasco Basin west of the Columbia River in Washington state that shows how boulders piggybacked icebergs from what is now Montana and came to rest at elevations as high as 1,200 feet. Although glacial deposits of rocks and boulders are common, especially in the upper Midwest, "There probably isn't anyplace else in the world where there are so many rocks that rafted in on icebergs," said Bruce Bjornstad, a geologist at the Department...

Filed at 2:33 p.m. ET WASHINGTON (AP) -- The icebergs breaking away from Antarctica in recent months -- some as big as small states -- are part of a process scientists say marks a return to ice conditions of years past. Several ice shelves around the continent have been growing in recent years, a process that has puzzled researchers concerned about possible global warming. In the last three months -- autumn there -- several icebergs, one the size of Delaware and another nearly as big as Chesapeake Bay, have broken free. ``The icebergs that have calved in last couple of...

Breakaway Bergs Disrupt Arctic Ecosystem WASHINGTON, DC, May 9, 2002 (ENS) - Another large iceberg has newly calved from the Ross Ice Shelf, the National Ice Center has confirmed. Iceberg C-18 is the latest in a series of bergs to break away from the warming Antarctic ice mass. National Ice Center analyst Judy Shaffier spotted the new iceberg Sunday while performing a weekly satellite image analysis of the Ross Sea using an image from the Defense Meteorological Satellite Program. The Ross Ice Shelf is a large sheet of glacial ice and snow extending from the Antarctic mainland into the...
