Sea Level Rise Threatens Larger Number of People Than Earlier Estimated

More people live close to sea coast than earlier estimated, assess researchers in a new study. These people are the most vulnerable to the rise of the sea level as well as to the increased number of floods and intensified storms. By using recent increased resolution datasets, Aalto University researchers estimate that 1.9 billion inhabitants,

Ice Sheet Modeling of Greenland, Antarctica Helps Predict Sea-Level Rise

LIVERMORE, Calif.–The Greenland and Antarctic ice sheets will make a dominant contribution to 21st century sea-level rise if current climate trends continue. However, predicting the expected loss of ice sheet mass is difficult due to the complexity of modeling ice sheet behavior. To better understand this loss, a team of Sandia National Laboratories researchers has

NASA, University Study Shows Rising Seas Slowed by Increasing Water on Land

New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise. A new study by scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of California, Irvine, shows

New Study Finds Steep Increase in East Coast High-Tide Floods

WASHINGTON, Oct. 8, 2014—Flooding during high tides—something that rarely occurred in the past—is now common in some places and is projected to grow to the point that sections of coastal cities may flood so often they would become unusable in the near future, according to a report the Union of Concerned Scientists (UCS) released today,

Shrinking Arctic Ice Prompts Drastic Change in National Geographic Atlas

The shrinking of the Arctic ice sheet in the upcoming 10th edition of the National Geographic Atlas of the World is one of the most striking changes in the publication’s history, geographers say. The reduction in multiyear ice—commonly defined as ice that has survived for two summers—is so noticeable compared with previous editions that National Geographic

Hurrricane Sandy to Katrina: Two Disasters Exceeding $200 billion in Damages Set Stage for Opening of 2014 Hurricane Season

At a recent summit in New York’s financial district, the news was pay now or pay much more later. Speaker after speaker either showed scientific evidence of potential disasters due to sea level rise or the enormous costs that are sure to follow the new reality of disaster brought about by the most costly storms,

New Tide Gauge Uses GPS Signals to Measure Sea Level Change

A new way of measuring sea level using satellite navigation system signals, for instance GPS, has been implemented by scientists at Chalmers University of Technology in Sweden. Sea level and its variation can easily be monitored using existing coastal GPS stations, the scientists have shown.

Climate Change Report Warns of Dramatically Warmer World This Century

Like summer’s satellite image of the melting Greenland ice sheet, a new report suggests time may be running out to temper the rising risks of climate change. “Turn Down the Heat: Why a 4°C Warmer World Must be Avoided,” warns we’re on track for a 4°C warmer world marked by extreme heat-waves, declining global food stocks,

North Carolina Wishes Away Climate Change

Some lawmakers will go to great lengths to deny the reality of climate change. But this week, North Carolina lawmakers reached new heights of denial, proposing a new law that would require estimates of sea level rise to be based only on historical data—not on all the evidence that demonstrates that the seas are rising
