It is widely believed and widely reported in the mainstream news media that because of global warming (directly tied to melting of glaciers) sea level will be rising rapidly in the next 10 or 50 years and that many low-lying coastal regions will be inundated by sea water. Recently there were some of the highest "King" tides on record in the Puget Sound Region (where I live). In our yard the high tide on the morning of December 27, 2022 was above our bulkhead for the first time in the eleven years that we lived here. The South Park neighborhood in Seattle saw a great deal of flooding and many residents were displaced. The sky is falling, the sky is falling. I believe that some of these projections were made in the 1990s, forecasting out 30-50 years. We're already 30 years past 1990.

So I looked at the data. The worlds main repository if specific information about changing sea levels is at the Pemanant Service for Mean Sea Level in Liverpool, England. They maintain data from hundreds of water level gauges around the world including Seattle. The Seattle data is provided to them by NOAA (The National Oceanic and Atmospheric Administration); the folks that run the weather service. Their Seattle data is complete back to 1899.

Their data clearly shows that Yes, Virginia sea level is rising. But, between 1900 and 2022 the overall rise has been 10 inches. In the decade between 2013 and 2022 the rise was 3 inches. But before you say that this shows an increasing trend...during the 10 years between 1993 - 2003 the sea level retreated. This decade was just after the sky is falling scientists first started blaming changing climate and changing sea level on mankind's activities. In fact these 10 years closely followed the 1991 eruption of Mt Pinatubo in the Phillipines which much more heavily impacted climate change than anything people do.

The King Tides that were experienced in December 2022 where long ago forecasted by NOAA. They are totally a factor of the relationship of the Earth, the Moon and The Sun. The actual (extreme height) resulted from extremely low barometric pressure which coincided with the forecasted tides.

Yes, The trend for sea level is that it has been rising for over 120 years. It will probably continue to rise slowly. Due to a lot of factors. However, it is rising much more slowly than scientists have forecasted. And it is much more the result of factors that are out of the control of human residents of this planet.
