On March 11, 2011, a magnitude 9.0 earthquake—one of the largest ever recorded—occurred 80 miles off the coast of Japan.Aea level rise corroborates other evidence of global warming The blue line in the graph below clearly shows sea level as rising, while the upward curve suggests sea level is rising faster as time goes on.The upward curve agrees with global temperature trends and with the accelerating melting of ice in Greenland and other places.Other skeptic arguments about sea level concern the validity of observations, obtained via tide gauges and more recently satellite altimeter observations.Tide gauges must take into account changes in the height of land itself caused by local geologic processes, a favorite distraction for skeptics to highlight.
