Rahmstorf continues displaying his ignorance today on RealBadClimateBS
Nature Climate Change publishes two new sea-level papers today. One, by Sallenger et al., is an analysis of US tide gauge data. The main finding is that there is a “hotspot” of acceleration in sea level rise over the past sixty years on the US Atlantic coast, with the largest acceleration found between Cape Hatteras and Boston. The authors argue that this pattern is consistent with a weakening of the Atlantic overturning circulation (and hence their first reference is to our 2005 paper where we show this sea-level pattern in our model). In my opinion an intriguing possibility that warrants further investigation. There could be other causes, like interdecadal changes in the wind field.
Tide gauges show significant sea level rise in that region ….
but satellites don’t ….
Satellites measure the absolute elevation of the sea surface, whereas tide gauges measure the height of the sea relative to the land. If tide gauges show a large increase in sea level, but satellites don’t – the only rational explanation is that the land is sinking.
This is very basic science, and the failure of the experts to realize this is yet another indication that these people are incompetent.
