I suppose all the global warming advocates who own beach houses are going to start selling the on the cheap now, right?
The study by the National Research Council gives planners their best look yet at how melting ice sheets and warming oceans associated with climate change will raise sea levels along the country’s Pacific coast. It is generally consistent with earlier global projections, but takes a closer look at California, Oregon and Washington.
Although the six inches expected for California by 2030 seem minor, the report estimated that sea levels there will be three feet higher by 2100. About 72 percent of the state’s coast is covered by sandy cliffs, and the rest include beaches, sand dunes, bays and estuaries.
“Rising seas increase the risk of coastal flooding, storm surge inundation, coastal erosion and shoreline retreat, and wetland loss,” the report said. “The cities and infrastructure that line many coasts are already vulnerable to damage from storms, which is likely to increase as sea level continues to rise and inundate areas further inland.”
Gosh, that sounds terrifying.
Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world’s ocean in response to global warming.
While the rise of the global ocean has been remarkably steady for most of this time, every once in a while, sea level rise hits a speed bump. This past year, it’s been more like a pothole: between last summer and this one, global sea level actually fell by about a quarter of an inch, or half a centimeter.
This was during the same time that the Earth had a fever and we were all going to die in a fiery ball of carbon dioxide induced world wide catastrophe.
Beside, President Obama told us his election would cause the seas to stop rising.
So, California can rest easy. Obama’s got their back.
