  1. Utter nonsense. Sea level appears to be rising at a small and steady 3mm per year. It is neither acclerating or decelerating. The trend is linear. As regards NOAA tide gauge data, let's look at some examples from around the world. N.B. All sites show a linear Relative Sea Level Trend: Kanmen, China 2.40mm/yr; Sydney, Australia 0.75mm/yr; Ferandina Beach, Florida 2.20mm/yr; Los Angeles, California 1.04mm/yr; Mera, Japan 3.8mm; Cascais, Portugal 1.32mm/yr. Remember, all linear over many decades, or more than a century. No acceleration (or deceleration for that matter). Anyway, if you prefer satellite data NOAA's trend was +3.0mm/year Global Mean Sea Level (1993-2022), again linear last time I looked (but hey, it may have accelerated in the last month). NASA satellite data (1993-present) for Global Mean Sea Level shows a linear rise of 3.3mm per year. All linear. No acceleration, so no relationship to the exponential increase in CO2 in the atmosphere. It's going to be decades before even your big toe is submerged.
