Is There Evidence of 'Fingerprints' in North Atlantic Tide Gauge Records?

Sea level is rising but clear evidence of an increase in the rate of rise has proved elusive. Recent observations have suggested that there has been a marked increase in the rate of Greenland melting. Increased melting from high latitudes should produce an identifiable pattern of sea level change ('fingerprints') that may provide evidence of an acceleration in the rate of sea level rise. Here we show evidence of recent changes in the latitudinal pattern of sea level change from North Atlantic tide gauges. These gauges, selected from the most well sampled ocean basin, show a latitudinal pattern of sea level change over the past 60 years which are indicative of an acceleration in the rate of sea level rise and consistent with higher Greenland melting.
