Maybe not so simple. Deserts have in recent years been discovered as possibly a huge carbon sink that has been soaking up atmospheric CO2 and storing it as inorganic carbon (both in soil and in ground water). How will flooding with sea water affect that? See: http://www.sciencemag.org/content/320/5882/1409 (2008) "A CO2-gulping desert in a remote corner of China may not be an isolated phenomenon. Halfway around the world, researchers have found that Nevada's Mojave Desert, square meter for square meter, absorbs about the same amount of CO2 as some temperate forests. The two sets of findings suggest that deserts are unsung players in the global carbon cycle.
