The Science of Global Warming: Sea Rise and Glaciers

Planet Ark reports that two articles published in Science today concern global warming.  First, a study by Miller et al indicates that sea level has risen at double the rate during the last 150 years (about a centimeter a year) than the rate during the preceeding 5000 years.  Miller says that half the sea level rise can be attributed to natural warming -- the remainder is attributable to human activity.  150 years, of course, corresponds nicely with the intensified use of fossil fuels since the Industrial Revolution.  A study by Stocker, et al indicates that carbon dioxide levels were relatively stable over the last 650,000 years until about 200 years ago.  The rise during the last 200 years is 200 greater than any previous rise.
