I’ve noted innumerable times that the average sea rise over the last 7,000-8,000 years, a period used as it came after the big melt from the end of the last glacial age, is 6-8 inches per century. During a warm period, one would expect at least double that, as the cool periods last longer and can even have negative sea rise. In fact, sea rise during the 20th Century was exactly average, at 7 inches. And here’s the Washington Post’s resident climahysteric, Chris Mooney
Seas aren’t just rising, scientists say — it’s worse than that. They’re speeding up.
On a warming Earth, seas inevitably rise, as ice on land melts and makes its way to the ocean. And not only that — the ocean itself swells, because warm water expands. We already know this is happening — according to NASA, seas are currently rising at a rate of 3.5 millimeters per year, which converts to about 1.4 inches per decade.
So, the lower end of expectations. But, you know, doom
However, scientists have long expected that the story should be even worse than this. Predictions suggest that seas should not only rise, but that the rise should accelerate, meaning that the annual rate of rise should itself increase over time. That’s because the great ice sheets, Greenland and Antarctica, should lose more and more mass, and the heat in the ocean should also increase.
Yes, if it was a normal warm period, we should expect more than 1.4 inches per decade. Of course, the predictions are coming from computer models. Then it gets cute
This record actually shows a decrease in the rate of sea level rise from the first decade measured by satellites (1993 to 2002) to the second one (2003 to 2012). “We’ve been looking at the altimeter records and scratching our heads, and saying, ‘why aren’t we seeing an acceleration in the satellite record?’ We should be,†said John Fasullo, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado.
So, they went and found an excuse for what is just a mostly natural event, in order to Blame Mankind
In a new study in the open-access journal Scientific Reports, however, Fasullo and two colleagues say they have now resolved this problem. It turns out, they say, that sea level rise was artificially masked in the satellite record by the fact that one year before the satellite launched, the Earth experienced a major cooling pulse.
That came from the explosion of the volcano, Mt. Pinatubo. So, a natural event can cause a climatic change, but, nature can’t cause warming. And Warmists have to find excuses to continue propping up their cult.
