OOPS!!! You know what that means? More ice...

Remember all those warnings about rising sea levels flooding coastlines around the world due to man-made global warming?

Global Sea Level Quarter of an Inch Lower Than Last Summer

Juliet Eilperin

The global sea level this summer is a quarter of an inch lower than last summer, according to NASA scientists, in sharp contrast to the gradual rise the ocean has experienced in recent years.

The change stems from two strong weather cycles over the Pacific Ocean — El Niño and La Niña — which shifted precipitation patterns, according to scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif. The two cycles brought heavy rains to Brazil and Amazon, along with drought to the southern United States.

Researchers monitored the ocean’s width, height, temperature and salinity through satellites and robot-operated floats, and presented their findings Aug. 8 and 9 at the annual Gravity Recovery and Climate Experiment (GRACE) Science Team Meeting in Austin, Tex.

“This year the continents got an extra dose of rain, so much so that global sea levels actually fell over most of the last year,” said Carmen Boening, an oceanographer and climate scientist at the lab, in a statement.
