Poseidon

In 1993 the US sent up a satellite named Poseidon and its purpose was to measure sea level to accuracies never before achieved. Between 1993 and 2005 sea level rose an average of 3mm’s per year and between 2005 and 2010 it rose 1mm per year. That is 17 year average of about 2.5 mm’s per year. That means in ten years it would rise 2.5 cm’s and in 100 years it would rise 25 cm which is ten inches. That is less than one foot over the next 100 years

Al Gore’s book on global warming was published in 2006 and as you can see he access to ten years of data from Poseidon which he chose to ignore when he suggested that sea level could rise 20 feet

The film, An Inconvenient Truth, suggested that the sea would rise up to 20ft "in the near future" as the ice in Greenland or Western Antarctica melts.


This tells me that this was not an honest mistake but rather a deliberate attempt to mislead.
