Western Antartica's immense glaciers are melting fast and giving up ice to the sea at a rate that is considered already past "the point of no return," according to recent research work done by two different groups of scientists. The resulting scenario is compelling: an increase in the world sea levels of 4 feet or more in the next centuries, according to findings announced Monday by scientists from the University of Washington, the University of California-Irvine and the Jet Propulsion Laboratory at NASA. "It truly is a startlingly disturbing situation," says Pennsylvania State University glaciologist Sridhar Anandakrishnan, who was not associated with any of the research studies. "This is a big part of West Antarctica, and it appears to have been pushed violently over the edge." The researchers claim the glaciers are most certainly bound to be lost. One study confirms that a river of ice named Thwaites Glacier is possibly starting to collapse and that complete collapse is likely to occur. A second research illustrates that six glaciers are giving up ice into the sea at an ever-increasing rate. At that rate, there will be a 4-feet increase in the sea-level, states study author Eric Rignot, a glaciologist at the University of California-Irvine, and NASA's Jet Propulsion Laboratory.

LETTER: Scientific findings on climate are real, not optional The letter by James Policelli ("America is heading down dangerous path," Jan. 22) is proof that the far right lunatic fringe disavows science. On the next page of that day's paper was a statement by the National Oceanic and Atmospheric Administration that 2013 was the fourth warmest year on record. Policelli would likely claim that NOAA is a puppet of the Obama administration and has broadcast false information to further a socialist agenda. (What!) Let's look at some indisputable facts. A comparison of NASA space shots of polar ice caps clearly indicates they are shrinking. Ocean levels have been measured to be rising. (Where do you think the melting polar ice caps go?) As a scientist, I have never been amused by junk science or those who espouse it. As one who helped develop some of the spectroscopic fingerprints used to monitor ozone-destroying man-made molecules in the upper atmosphere, I find the climate change denials of the far right lunatic fringe to be extremely offensive and exceptionally dangerous.
