Sea level rise: Global warming's yardstick
Description: Global sea levels have been ticking steadily higher by about an eighth of an inch (3.2 millimeters) each year since scientists began measuring them two decades ago. That's why scientists were shocked in 2010 and 2011, when there was a quarter-inch (five-millimeter) drop in sea level - a sudden reversal of the trend. Using NASA's GRACE mission, which basically weighs water to tell us how much is present in different parts of the world, both in the ocean and on land researchers found there was actually less water in the ocean.
