has sea level risen in the last 50 years

Theglobal average sea level has risen over 7 inches in the past 100 years. A few inches may not seem like much, but every inch of sea level rise covers 50-100 inches of beach. If the ice keeps melting, global sea level could rise more than 20 feet. That would put a lot of coastlines under water. Were unlikely to see the 20-story swells that Capra described, as most scientists today predict 5 to 6 feet of sea-level rise in South Florida by 2100. Yet climate change very much remains an 1992- 2022 PNG The altimetry data also show that the rate of sea level rise is accelerating.
