The report said a rise of one meter, the best case scenario, was not “unlikely.” It would put 1,155 square kilometers of the country’s coast under water by 2050; nine meters, the worst case, would submerge most of Abu Dhabi and much of Dubai.
A one meter rise would cost Abu Dhabi more than 10sq km of built-up area and more than 100 sq km of urban greening.
The report, Climate Change: Impacts, Vulnerability and Adaptation was commissioned by the Environment Agency – Abu Dhabi (EAD) and compiled by the Stockholm Environment. It warns that unless future development planning accounted for the changes, there would be unacceptable economic damages for the UAE’s coastal zones.
The International Panel on Climate Change, the world’s most authoritative scientific body on the subject, estimates that sea levels will rise by between 0.37 metres and 0.59m by the turn of the century. The actual fluctuation will depend on a number of variables, including how much global temperatures rise, and how that will affect glaciers and snow cover on polar caps.
