The reason we've switched from "global warming" to "climate change" is that there are other effects that are only indirectly related to the thermometer. Sea level rise is a particular concern because it has "momentum." Meaning that even if we stopped adding CO2 to the atmosphere tomorrow, glacial melting would continue for decades, raising sea levels and threatening our low lying cities.

@ElwoodBlues That's weird, I just got back from San Diego and we went to Mission Bay. The ocean there has
not risen in the decades I've been going. Probably because it's not connected to other oceans. 🤔😉

@DogMan Gosh, according to the City of San Diego, you are DEAD WRONG!!!
During the 20th century, sea levels rose 0.71 feet in San Diego. By 2100, San Diego could experience another 3.6 to 7 feet of sea level rise. Sea level rise will mean more flooding and faster rates of erosion along the coastline.

Perhaps the City of San Diego is more careful about their measurements than you are. Or maybe it's a GiAnTt CoNsPiRaCy!!!

@ElwoodBlues Oh, OK, so during the 1900's it went up about 8". So that would be around .08 inches per year, or
8 tenths of an inch per decade. How did I miss that?
OK, so we know that about the 20th century, what about the last 25 years?

@DogMan Take a look at the map I posted; pay attention to the east coast. San Diego isn't the only seaside city we have.
