Sea Level Rise 1. High confidence from paleo sea level data & few long tide gauge records that there was an increase in the rate of MSLR during the late 19th and early 20th centuries; San Francisco Brest Swinoujscie

Sea Level Rise 2. Virtually certain from tide gauge & satellite observations that global MSL has risen at a average rate of: a. 1.7 mm/yr 20th century ; b. 3.3 mm/yr 1993-2018;
