Foot in their mouths

People trying to push global warming worries have a new tactic - enshrining their projections into government rule making.
They project sea level rise of 5.5 to 7.2 feet by 2115.
So building in those areas should be restricted based on those projections.
Unfortunately, they have to deal with historical data.
They use a baseline from 1992 - 23 years ago.
They claim sea level rise of six inches (.5 feet) since then.
Using that data, in 100 years, sea level rise will be less than 2.5 feet.
The scary maps are a lot less scary when you reduce sea level rise by two-thirds.
