The American Institute of Physics hosts a large and detailed website/publication called The Discovery of Global Warming. The Scientific American shares a more succinct outline, part of which is copied below. Given some of the the 'superstorms' like Sandy, I wonder, as a construction guy, what will the implications be for building codes? The kinds of baseline and criteria extremes will have to shift codes to accommodate changing conditions for wind and rain the may have a drastic effect on construction costs.
