TOPEX/JASON Sees 22-Year Sea Level Rise

This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1, and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches. The color range for this visualization is -7 cm to +7 cm (-2.76 inches to +2.76 inches), though measured data extends above and below 7cm(2.76 inches). This particular range was chosen to highlight variations in sea level change. Download the visualization: http://svs.gsfc.nasa.gov/cgi-bin/deta....

This winter, areas across the globe experienced a shift in rain patterns due to the natural weather phenomenon known as El Niño. New NASA visualizations of rainfall data show the various changes to California. According to the National Oceanic and Atmospheric Administration, El Niño was expected to produce wetter-than-average conditions from December 2015 to February 2016. Scientists refer to historical weather patterns and to look at trends of where precipitation normally occurs during El Niño events. Also, several factors—not just El Niño—can contribute to unusual weather pattern.
