Sea Level Rise: One disturbing activity by some government entities is using the highly speculative projections of future sea level rise to frighten the public The purpose appears to be to promote the false belief that humans can stop sea level rise by limiting or controlling carbon dioxide emissions. A common trick is using the widely ranging projections of the UN Intergovernmental Panel on Climate Change (IPCC). These projections are based on global climate models that have not been validated, and use of a few highly questionable studies based on a small sample of occurrences that cannot be generalized, globally.
In his presentation at the Ninth International Conference on Climate Change (ICCC9), former NASA meteorologist Thomas Wysmuller highlighted some of the difficulties in arriving at accurate estimate of global sea level rise. Even satellite measurements have significant errors, containing significant noise from wave action near the coast lines.
Wysmuller states that we have three different metrics for estimating sea levels: 1) tidal gages with an average of 1.7 mm per year; 2) TopeX/Poseidon/Jason 1 & 2 satellites with a rise of 3.1 mm per year; and ENVISAT satellite with a rise of 0.5 to 2.5 mm per year. Importantly, all the sources indicate linear trends!
