Projected sea level rise on South Carolina coast 2030

A peer-reviewed study by P. Barford, R. Durairajan,and C. Barford has used data from the Internet Atlas and projections by NOAA of sea level rise affecting U.S. coasts to ascertain the impact of the rising sea level on the internet. The Internet Atlas provides a comprehensive global map of the internet’s physical structure.  The analysis suggests that by the year 2033 more than 4,000 miles of buried fiber optic conduit will be underwater and more than 1,100 internet hubs will be surrounded by water. The study was presented at the Applied Networking Research Workshop, a meeting of the Association for Computing Machinery, the Internet Society and the Institute of Electrical and Electronics Engineers.
