Catastrophic sea level rise is one of the most valued hole cards played by alarmists in the global warming debate. In An Inconvenient Truth, Al Gore showed computer generated images of what Manhattan would look like if sea level rose 20 feet. Building on this theme, elevation charts of coastal cities have become a staple in global warming presentations by Al Gore wannabes. But what happens when sea level in the real world does not rise nearly as much as alarmists predict? If you are a NASA-funded gatekeeper of sea level data, you merely doctor the data.
Faced with the embarrassing fact that sea level is not rising nearly as much as has been predicted, the University of Colorado’s NASA-funded Sea Level Research Group has announced it will begin adding a nonexistent 0.3 millimeters per year to its Global Mean Sea Level Time Series. As a result, alarmists will be able to present sea level charts asserting an accelerating rise in sea level that is not occurring in the real world.
Human civilization readily adapted to the seven inches of sea level rise that occurred during the twentieth century. Alarmists, however, claim global warming will cause sea level to rise much more rapidly during the present century. United Nations Intergovernmental Panel on Climate Change (IPCC) computer models project approximately 15 inches of sea level rise during the 21st century. That’s more than double the sea level rise that occurred during the twentieth century. A more “mainstream” prediction among alarmists is 3 feet of sea level rise this century. Some alarmists have even projected 20 feet of global sea level rise this century.
Satellite measurements, however, show global sea level rose merely 0.83 inches during the first decade of the 21st century (a pace of just 8 inches for the entire century), and has barely risen at all since 2006. This puts alarmists in the embarrassing position of defending predictions that are not coming true in the real world.
