Australian sea level rises exaggerated by 8 fold (or maybe ten)

The Daily Telegraph exposed the NSW state government protecting the world from some dangerous scientific analysis of sea-levels.

Doug Lord examined 120 years of tidal data from Sydney Harbour, and found a 1 mm year on year rise which didn’t fit with the 900 mm rise projected by the Wizards of Climate Change at the Department. He finds the official figures exaggerate ten fold.

Ken Stewart has taken the dangerous data from 19 sites around Australia and finds it averaged 1.4 mm/year over the last 100 years. He finds about an 8-fold exaggeration. This is another sordid tale in the Science-perverted-for-PR category.
