A group of Japanese researchers has found that carbon dioxide levels over the Antarctica rose by over 2.6 percent from six years ago - the first such detection of an increase in a "greenhouse" gas above the southern continent, group members said Tuesday.    Many scientists fear carbon dioxide, produced by burning fossil fuels and other industrial processes, may be causing global warming by trapping heat in the Earth's atmosphere...

Global warming is melting the Arctic ice faster than expected, and the world&#39;s oceans could rise by about a meter by 2100, swamping homes from Bangladesh to Florida, the head of a study said.

Glaciers in Antarctica are thinning faster than they did in the 1990s and researchers have discovered an unexpected folded section deep beneath the ice cap, findings that may indicate the ice is less stable than had been thought.    Glaciers in West Antarctica are discharging 60 percent more ice into the sea than they are accumulating from snowfall, a research team led by Robert Thomas at NASA Goddard Space Flight Center in Wallops Island, Va., reports in Thursday's issue of the journal Science...
