Don't know anything about Abu Dhabi, do you?
Abu Dhabi lies in the middle of a vast stretch of salt flats that are barely above the level of the Persian Gulf. Any sea level rise will flood the entire city. Conversely, pumping out ground water will cause land subsidence, also flooding the city. together, they'll create a new Netherlands of the Desert.
Abu Dhabi's future requires three things; draconian population control, draconian water conservation, and development of energy efficient solar distillation factories.
