NOTE ON POPULAR POSTS

The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

ANTARCTIC MELTING SINCE 1947 SAYS USGS

New data shows that ice-shelves are retreating in the southern section of the Antarctic Peninsula due to climate change, which can can cause glaciers to retreat and a rise in sea-levels if warming continues, threatening coastal communities and low-lying islands.

Research by the U.S. Geological Survey is the first to document that every ice-front in the southern part of the Antarctic Peninsula has been retreating overall from 1947 to 2009, with the most dramatic changes occurring since 1990. The USGS previously documented that the majority of ice fronts on the entire Peninsula have also retreated during the late 20th century and into the early 21st century.

The ice-shelves, which are attached to the continent and floating, hold in place the Antarctic ice-sheet that covers about 98% of the Antarctic continent. As they break off, it is easier for outlet glaciers and ice-streams to flow into the sea and raise it.
