Guardian: NASA researchers have determined that global sea levels have risen an average of nearly 8 cm since observations began in 1992. The findings, based on some 23 years of satellite data, were presented during a media conference on Wednesday. The rise is not uniform across the globe, however, due to ocean currents and other factors. Whereas some areas may actually experience a drop in water level, others may see a rise of nearly 23 cm. And by the end of the century, global sea levels could go up by as much as 3 m. The researchers say that one-third of the rise is due to the expansion of warming ocean water, one-third to ice loss from the Greenland and Antarctic ice sheets, and one-third to melting mountain glaciers.
