guesstimates
and do we know what ill effects the planet and mankind have endured from sea level rise from the past 120years???
Cause this stuff - these "risks" seem rather vague

Risks from sea level rise
TS.C.5 Coastal risks will increase by at least one order of magnitude over the 21st century due to committed sea level rise
impacting ecosystems, people, livelihoods, infrastructure, food
security, cultural and natural heritage and climate mitigation
at the coast. Concentrated in cities and settlements by the sea,
these risks are already being faced and will accelerate beyond
2050 and continue to escalate beyond 2100, even if warming
stops. Historically rare extreme sea level events will occur annually by 2100, compounding these risks (high confidence).
