While climate change and sea-level rise are book-length subjects, this column will attempt to highlight major aspects of the problem. The World Ocean has an area of about 139 million square miles.

From 2000 to 2100 the estimated rise will be 7.5 feet. Is this a good number? Maybe it’s too small. As computer models have improved they show that the rise has been consistently underestimated.
