Climate-change\textendashdriven accelerated sea-level rise detected in the altimeter era
Using a 25-y time series of precision satellite altimeter data from TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3, we estimate the climate-change\textendashdriven acceleration of global mean sea level over the last 25 y to be 0.084 \textpm 0.025 mm/y2. Coupled with the average climate-change\textendashdriven rate of sea level rise over these same 25 y of 2.9 mm/y, simple extrapolation of the quadratic implies global mean sea level could rise 65 \textpm 12 cm by 2100 compared with 2005, roughly in agreement with the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report (AR5) model projections.
