I have a leftist sister in Kalifornia that will strongly disagree with you. She told me the water rises at different levels in California beaches due to glowbull warming. Of interest, her and her daughter do not recognize Trump as their President. I can’t stomach talking to those potheads.
If there were any part of the globe that would reveal sea level rise, it might be equatorial islets like the Maldives (which are still nicely above water.).
