Today the U.S. National Research Council released a synthesis of reports from thousands of scientists in 60 countries who took part in the International Polar Year (IPY) 2007-08, the first in over 50 years to offer a benchmark for environmental conditions and new discoveries in the polar regions. University of Massachusetts Amherst geosciences researcher and expert in the paleoclimate of the Arctic, Julie Brigham-Grette, co-chaired the NRC report, "Lessons and Legacies of the IPY 2007-08"...

Image 1 - Crust Below Mississippi Delta Still Subsiding, Just Much Slower
2012-04-04 04:21:55

New data suggests that the Mississippi Delta is still sinking, but at a much slower rate than previously estimated. A new paper published in the journal Earth and Planetary Science Letters reports these new findings. Geoscientists arrived at this new conclusion after comparing detailed sea-level reconstructions from different areas of coastal Louisiana. The new findings not only reveal new information about the subsidence of the Mississippi Delta, but also admonishes the continuous...

Are Ocean Levels And Temperatures On The Rise?
2012-04-02 13:29:53

A new study has revealed a global warming and rising of the oceans. Contrasting ocean temperature readings from the 1870s with modern readings, this study reveals an upward rising trend spanning over 100 years. Dan Roemmich, a Scripps Institution of Oceanography at UC San Diego physical oceanographer led the research. He found a .33 degree Celsius (.59-degree Fahrenheit) increase on average in the top portions of the ocean, down to 700 meters. Ocean surface temperatures, however, saw the...

Image 1 - Global Sea Level Could Rise As Much As 70 Feet In The Future
2012-03-21 04:04:57

Scientists looked back in time - in the geologic record - to see the future Even if humankind manages to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit)--as the Intergovernmental Panel on Climate Change (IPCC) recommends--future generations will likely have to deal with a completely different world. One with sea levels 40 to 70 feet higher than at present, according to research results published this week in the journal Geology. The scientists, led by Kenneth...

Rising Sea Levels Could Boost Storm Surges
2012-03-16 05:19:24

Sea level rise due to global warming has already doubled the annual risk of coastal flooding of historic proportions across widespread areas of the United States, according to a new report from Climate Central. By 2030, many locations are likely to see storm surges combining with sea level rise to raise waters at least 4 feet above the local high-tide line. Nearly 5 million U.S. residents live in 2.6 million homes on land below this level. More than 6 million people live on land below 5 feet;...

Evidence In Bahamas And Bermuda Suggests Increased Rise In Sea Levels
2012-03-15 11:45:55

Scientists are now predicting sea levels will climb another several inches -- or even a few feet -- by the year 2100, according to recent studies. Studying cliffs and ancient reefs on the sub-tropical islands of the Bahamas and Bermuda, scientists are investigating global sea rise and comparing these results against data from more than a century ago. The Bahamas and Bermuda have been attracting fossil hunters for many years. The land on the Bahamas, for example, is built on a foundation...

But projections for increase today still loom large The seas are creeping higher as the planet warms. But how high will they 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...

Nearly four million Americans, occupying a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests. A new study, published today, 14 March, in IOP Publishing's journal Environmental Research Letters, asserts that around 32,000 km2 of US land lies within one vertical meter of the high tide line, encompassing 2.1 million housing units where 3.9 million people live. For this study, the...

The Greenland ice sheet is likely to be more vulnerable to global warming than previously thought. The temperature threshold for melting the ice sheet completely is in the range of 0.8 to 3.2 degrees Celsius global warming, with a best estimate of 1.6 degrees above pre-industrial levels, shows a new study by scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Universidad Complutense de Madrid. Today, already 0.8 degrees global warming has been observed. Substantial...

Visualizations Help Communities Plan For Sea-level Rise
2012-02-20 04:00:08

Researchers at the University of British Columbia have produced computer visualizations of rising sea levels in a low-lying coastal municipality, illustrating ways to adapt to climate change impacts such as flooding and storms surges. The researchers are working with a municipality south of Vancouver, Canada that is surrounded by water on three sides and is expecting the sea-level to rise by 1.2 meters by 2100 — a change that would affect a number of waterfront homes, inland suburban...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
