Like the east coast of the U.S , Ireland was under ice sheet. The crust is recovering from the weight and parts are sinking, which gives the appearance of sea level rise. https://news.harvard.edu/gazette/story/2019/02/study-of-sea-level-rise-finds-land-sinking-along-east-coast/
How can one tell either phenomenon from these minuscule alleged measurements, is what I’d like to know.
I have come to the conclusion that some people are willfully ignorant of logic and as long as the story they get fed supports their worldview, they don't care if it stands up to examination.
The world's oceans are not like a concrete swimming pool. Over the past 100 years a whole lot of construction has occurred on coastlines. People want to live there, buildings and roadways are heavy, people need water to drink. Soil gets compacted, aquifers get drained, erosion pulls topsoil away, pollution kills off oyster beds etc... and that's before you account for plate tectonics and the effects of the last ice age. If you wanted to so something real about sea level measurements, you would return. Portions of coastal cities throughout the western world to nature. Restore an equilibrium with nature and allow wetlands that have been overtaken by humanity to be depopulated and the residents resettled to places where their existence doesn't insult Gaia so darned much.
yes, subsidence of land in many areas accounts for what is being reported as “sea level rise”.
