Building sea walls and other measures to protect coastal developments address the symptoms of climate change, not the cause. We need to support legislation to counteract global warming, such as Sen. Bernie Sanders' (I-Vt.) Climate Protection Act of 2013.
Insurance companies should think twice about offering storm insurance for coastal areas; or if they do, the premiums should be comparable to what Californians have to pay for earthquake insurance. This alone should discourage building in these areas.
Most of us are worried about rising sea levels; that's nice. We can all rest easy knowing that of the 22 Republicans on the House Committee on Space, Science and Technology, 10 are from states with no coastline, and both the chairman and his predecessor are from Texas, with all that implies about their relationships with Big Oil.
