The polar ice caps are melting. This removes weight from the crust underneath. The crust springs back up, and this causes tectonic plates to shift. These shifts result in earthquakes and tsunamis. Therefore, global warming caused the recent tsunami. Well, actually not, but this is how some of our more harebrained friends have interpreted a study not yet published by Bill McGuire of the University College London’s Hazard Research Center.
Mr. McGuire notes that large changes in sea levels and ice masses could very well have a significant effect on long-term plate tectonics, noting that this process is still ongoing as a result of the end of our most recent ice age about 10,000 years ago. But Roland Burgmann, a geologist at the University of California, Berkeley, comments that “It would take a long time to add up to a significant amount.”
Since AGW is posited even by its most ardent supporters to have begun with large scale industrial development in the twentieth century, the geological clock has only moved a few clicks of the second hand. Dire predictions of immediate global catastrophe are unsupported by the evidence, but very useful to the global warming industry, which has watched its torrent of grant money begin to dry up in the face of increasing scrutiny of its carelessness with data and its fondness for Cassandra-like predictions of this nature.
The irony of all this is that we will never know. Few alive today will enjoy lifespans of several thousand years, which is the time frame under which these kinds if events operate. One can make any number of bizarre predictions about the future when one is insulated from accountability by the languorous pace of geology. Real estate speculators hoping for beachfront homes in Vegas have a long time to wait. I think.
