Here’s geologist Patrick Barosh:

The fact is, climate and sea level are always changing. This is a fundamental tenet of the science of geology. The national recognition of climate change in the last dozen years is akin to discovering that the sun rises in the east; proposals to stop it amount to requiring the sun to rise in the west.

Barosh notes that a rising sea level was hardly new to the industrial era and, indeed, appears now to be happening at the same rate.  The world is not a constant; it moves.  In that spirit, he offers policy suggestions more in line with what one would expect from people who truly are concerned with the climate’s effect on humanity, rather than trying to use an environmental religion to increase their own political power:

Although climate changes are natural and cannot be stopped, we need to take measures to mitigate the damage, using the past sea-level rise rates and hurricanes as guides for the future. The movement of beaches and erosion of coastal bluffs should be fully recognized. This is a political, not a scientific, problem. The need is to better enforce coastal zoning to resist shoreline development with subsidized insurance, moving infrastructure inland rather than rebuilding it, discouraging sea walls and armored shores that cause more problems, and limiting rebuilding of destroyed shore buildings.
