*Projections for the future still loom large*
The seas are creeping higher as the planet warms. But how high could they go?
Projections for the year 2100 range from inches to several feet, or even more.
The sub-tropical islands of Bermuda and the Bahamas are two seemingly unlikely places scientists have gone looking for answers. (more…)
*History of influence of industrial revolution hidden in glacial ice*
New clues about how Earth’s remote ecosystems have been influenced by the industrial revolution have been uncovered. Until now they were locked away, frozen in the ice of glaciers.
So say scientist Aron Stubbins of the Skidaway Institute of Oceanography and colleagues. (more…)
Melting mountain glaciers are contributing to sea-level rise faster than at any time in the last 350 years, according to new research published in Nature Geoscience.
A research team from the University of Exeter, Aberystwyth University, and Stockholm University undertook a survey of the 270 largest outlet glaciers of the South and North Patagonian Icefields of South America. (more…)
ANN ARBOR, Mich.— In an effort to understand how fast sea level could rise as the climate warms, a University of Michigan researcher has developed a new theory to describe how icebergs detach from ice sheets and glaciers.
This process of “iceberg calving” isn’t well understood. While scientists believe it currently accounts for roughly half of the mass lost in shrinking ice sheets, current sea level rise models don’t take changes in iceberg calving into account in their predictions, says Jeremy Bassis, an assistant professor in the Department of Atmospheric, Oceanic and Space Sciences.

*Could Impact Water Supplies for Millions and Cause Flood Conditions*
This retreat impacts water supplies to millions of people, increases the likelihood of outburst floods that threaten life and property in nearby areas, and contributes to sea-level rise.
WASHINGTON — Glaciers that detach from the seafloor and begin floating create larger icebergs than glaciers that stay on the sea floor, researchers have found. Floating glaciers also produce icebergs more erratically.
