Over the past ten years, sea level at Lower Manhattan has trended downwards about four inches.
Meanwhile, this is what our top climate scientists are saying about Manhattan sea level.
Sea level rise at Manhattan has been averaging less than three millimeters per year since Republicans forced Democrats to give up their slaves in the 19th century. Most of this apparent rise has been due to the land sinking, and it will require more than 2,500 years for sea level to rise eight meters.
As is almost always the case with climate scientists, they either have no clue what they are talking about, or they are lying.
