Greenland Ice Sheet

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal Nature say that ocean warming could be causing a four-fold increase in ice loss on the Greenland Ice Sheet. The Greenland Ice Sheet is about a 2-mile thick layer of ice that covers the country. Glaciers that drain the ice sheet plunge into coastal fjords that are about 2,000 feet deep, helping to expose the ice sheet edges that contact the ocean. Oceanographers from Woods Hole Oceanographic...

Data from end of the last Ice Age confirm effects of climate change on oceans The first comprehensive study of changes in the oxygenation of oceans at the end of the last Ice Age (between about 10 to 20,000 years ago) has implications for the future of our oceans under global warming. The study, which was co-authored by Eric Galbraith, of McGill's Department of Earth & Planetary Sciences, looked at marine sediment and found that that the dissolved oxygen concentrations in large parts...

New research into the Earth's paleoclimate history by NASA's Goddard Institute for Space Studies director James E. Hansen suggests the potential for rapid climate changes this century, including multiple meters of sea level rise, if global warming is not abated. By looking at how the Earth's climate responded to past natural changes, Hansen sought insight into a fundamental question raised by ongoing human-caused climate change: "What is the dangerous level of global warming?" Some...

A mammoth iceberg that struck a glacier off Antarctica, dislodged a newer chunk of ice that could affect ocean currents and also lower the levels of oxygen in the world's oceans, according to Australian and French scientists. The two icebergs are drifting together about 62 to 93 miles off Antarctica after the Feb 12-13 collision, said Neal Young, a glaciologist for the Australian Antarctic Division. The first iceberg, measuring 60 miles long, collided with the Mertz Glacier Tongue and...

Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is loosing mass at an accelerating rate, reports a new study in Science. This mass loss is equally distributed between increased iceberg production, driven by acceleration of Greenland's fast-flowing outlet glaciers, and increased meltwater production at the ice sheet surface. Recent warm summers further accelerated the mass loss to 273 Gt per year (1 Gt is the...

The U.S. Department of Energy is at odds with researchers over the handling of a project aimed at showing the long-term effects of global warming on forests. The ongoing project began more than a decade ago. Researchers have pumped large levels once-liquefied carbon dioxide in carefully metered doses into clusters of trees in hopes of gauging how well they would respond to global warming. The loblolly pines planted in 1994 at Duke in North Carolina are located behind gates several miles from...

Ice core and ocean deposit comparisons show complex links between carbon dioxide levels, ocean currents and climate; may help explain past, present and future climate trends In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences. In a paper published last week in the journal Science, researchers...

By Timothy Gardner NEW YORK -- If the world continues to get warmer, vast amounts of methane gas trapped in ice under the sea could belch up and worsen climate change, according to a study. "We may have less time than we think to do something (about the prospect of global warming)," Dr. Ira Leifer, a marine scientist at University of California Santa Barbara, said in an interview. Leifer is the main author of a study that looks at how "peak blowouts" of melting undersea formations called...
