NOAA keeps track of sea level on thirteen islands around the world. The graph above shows their reported sea level rise rates in mm/year. The pink area shows the IPCC range of projected sea level rise 19-59 cm /century.
The average sea level rise rate on island locations is 1.22 mm/year, which is well below the low end of IPCC projections.
Even if there was no accretion of new material on these islands, it would take over 800 years for sea level to rise one metre, and 4,000 years to reach Hansen’s five metres.
Tuvalu thinks they can stop the seas by using renewable energy. Besides the obvious effect of the token actions of a couple hundred people on the global climate, it should also lower their tropical heating bills.
