global warming and sea levels are rising -- I think we need to look at where we are constantly building concrete and pavement structures that does not allow rain water to be absorbed. Instead we are building surfaces that exceed 200+ degree and that divert water to run off faster to streams that run into the ocean. California is sinking ( http://www.livescience.com/519... ) because of less ground water. If we can build water collection areas we can reverse the rising sea levels and address the hotter water going into our oceans. Just think, if a building has been around for 50 years then the water that would normally be absorbed into the ground has had to be diverted for entire existence of the building (50 years at 20 inches of water per year comes up to 100 inches of water that has to go somewhere) now lets try to imaging over four million km of pavement in the US alone (https://www.cia.gov/library/publications/the-world-factbook/fields/2085.html ).
