Ice sheet melting at the end of the last ice age may have caused sea levels to rise at 10 times the current rate, a study published Thursday by a team led by scientists from Britain s Durham University said.
Based on geological records, the researchers estimate that oceans worldwide rose 3.6 meters (11.8 feet) per century over a 500-year period some 14,600 years ago.
The findings raise a red flag about the potential today for rapid sea-level rise that could swamp coastal cities and densely populated deltas around the world.
On February 23rd the deepest snow depth in the state was 24” in Western Iowa at Little Sioux. Two weeks later, on March 9, the deepest snow is down to just 5.7” in Winthrop.

IT IS ALSO IMPACTING HOW MUCH ICE IS ON LAKE MICHIGAN. THIS WAS THE ICE COVERAGE ON FEBRUARY 21, 42% OF THE GREAT LAKES WERE COVERED. COMPARE THAT TO LAST YEAR WHEN THE PEAK WAS JUST UNDER 20%. NOW, 16% OF THE LAKES ARE ICE COVERED. ON FEBRUARY 21, NEARLY 26% OF THE WATER’S SURFACE WAS ICE. THAT IS ABOUT 10% MORE THAN THE LAST SEASON HIGHEST COVERAGE. FLASH FORWARD TO TUESDAY, NINE DAYS LATER, ICE COVER IS JUST 11%. THAT IS
