New Study Lowers Estimated Ancient Sea-Level Rise

March 14, 2012

The seas are creeping higher as the planet warms, but scientists have not yet reached a consensus about how high they may go. Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers. By pinpointing where shorelines stood on cliffs and reefs there during an extremely warm period 400,000 years ago, they hope to narrow the range of global sea-level projections for the future.
Climate Scientist Studies Ancient Shorelines

The seas are rising, as they have during past periods of warming in earth’s history. Estimates of how high they will go in the next few thousand years range from five meters, putting greater Miami underwater, to 40 meters, wiping most of Florida off the map. “The range of estimates is huge to the point of meaninglessness,” says

Scientists aboard the research ship the JOIDES Resolution recently drilled two kilometers into Earth’s crust, setting a new record for the deepest hole drilled through the seafloor on a single expedition.
Study Predicts Maximum Sea Level Rise Close to One Meter by 2100

July 27, 2009

A new study of sea level fluctuations over the last 22,000 years is the latest to predict that rising seas could reach close to one meter by the end of this century, consistent with the most recent sea level projections made by the Intergovernmental Panel on Climate Change (IPCC).

Warming Climate Drives Plankton and Penguins Poleward

Adélie penguins are flocking closer to the South Pole. A new study in the leading journal Science explains why: they’re following the food supply, which is moving southward with changing climate.
Look at Glaciers Past Suggests Greenland Melting Could Rapidly Heighten Sea Level

North American Ice Sheet Dwindled Fast in Conditions Like Today's

In the face of warming climate, researchers have yet to agree on how much and how quickly melting of the Greenland ice sheet may contribute to sea level rise.
