Internet map of sea level increase
A visit to website http://flood.firetree.net shows the impact of sea level rises from one to 14 metres in one metre intervals. The site uses Google’s mapping API and 50 Gbyte of raw data from NASA. One can view the extent of potential flooding for almost anywhere, in some cases to high resolution and detail. The inundation estimates are optimistic in most cases–correcting the inaccuracy would make the consequences of any rise look worse. |
