The 2011 La Niña was so strong that it caused global mean sea level to drop by 5 millimeters (0.2 inches), a new study shows. Since the early 1990s, sea level has been rising by about 3 millimeters (0.1 inches) per year, satellite data show. But between the beginning of 2010 and the middle of 2011, sea level fell by 5 millimeters (0.2 inches).
