The sea level chart I provided earlier (from a global warmist organization) indicates that the sea level rise has slowed, which you would expect since we are approaching a cyclical maximum.
Note that there are cycles upon cycles cycles, all with different periods, superimposed upon each other. In the 1970's scientists were worried about the coming ice age. Now they are worried about the opposite. Who is to say what they will be worried about 50 years from now. The cycles they are looking at are short term, "small" magnitude shifts. I'm talking about a long term, large magnitude, maximum point clearly shown in the graph I posted earlier. We don't know if we are at the natural maximum or not, so they can dismiss that unknown, and lobby for money.
But, as I say, if the global warmists were really serious, they would stop borrowing one trillion per year, start paying down the debt, in preparation to handle an issue that they say is our next WWII. But, they don't. They keep trying to destroy the country by increasing benefits and opening borders. When they get fiscally serious, I will be convinced that they think this risk is real.
