The topic of global warming, and whether or not it is because of human activity, is almost a Mute point...instead, we need to realize that it IS happening, and start preparing. If the studies conducted by reputable scientists are accurate, the coastal regions will be under water in another 1 to 2 hundred years. They project that the U.S. could lose as much as 17% of its current land mass....with places like Houston, New Orleans, Florida, and most of the major cities on the East coast being permanently flooded and becoming modern day examples of "Atlantis". As the human populations continue to expand, the situation will only get worse, and continue to accelerate. Even the most drastic measures that might be taken today...the total abandonment of fossil fuel use, etc.....would have little effect on the warming cycle, as there is already so much pollution in the atmosphere that it would take decades to reduce. The ice caps at the poles, and Greenland continue to melt at an increasing pace, and sea levels continue to rise. Eventually, there will be a massive migration inland from the coastal regions, and the economic/social implications will be mind boggling. The earth has gone through similar warming cycles in the past, but during those cycles, there were not billions of people living in low lying coastal regions.
Personally, if I were building anything today, with the idea of it still being here in the distant future, it would NOT be anywhere within 100 miles of the oceans, or less than 100 ft. above today's current sea levels.
