Seems I was wrong on changes to sea levels:
From: The Spectator,
Rising credulity Worth a read.
In 2003 the satellite altimetry record was mysteriously tilted upwards to imply a sudden sea level rise rate of 2.3mm per year. When I criticised this dishonest adjustment at a global warming conference in Moscow, a British member of the IPCC delegation admitted in public the reason for this new calibration: ‘We had to do so, otherwise there would be no trend.’
This is a scandal that should be called Sealevelgate. As with the Hockey Stick, there is little real-world data to support the upward tilt. It seems that the 2.3mm rise rate has been based on just one tide gauge in Hong Kong (whose record is contradicted by four other nearby tide gauges). Why does it show such a rise? Because like many of the 159 tide gauge stations used by the National Oceanic and Atmospheric Administration, it is sited on an unstable harbour construction or landing pier prone to uplift or subsidence. When you exclude these unreliable stations, the 68 remaining ones give a present rate of sea level rise in the order of 1mm a year.
If the ice caps are melting, it is at such a small rate globally that we can hardly see its effects on sea level. I certainly have not been able to find any evidence for it. The sea level rise today is at most 0.7mm a year — though, probably, much smaller.
We must learn to take the environmentalists’ predictions with a huge pinch of salt. In 2005, the United Nations Environment Programme predicted that climate change would create 50 million climate refugees by 2010. That was last year: where are those refugees? And where are those sea level rises? The true facts are found by observing and measuring nature itself, not in the IPCC’s computer-generated projections. There are many urgent natural problems to consider on Planet Earth — tsunamis, earthquakes, volcanic eruptions not least among them. But the threat of rising sea levels is an artificial crisis.
