Intraregional variability shows a complex response to regional and local forcing. Our wide sampling of actual to changes shows that glacier acceleration across the ice sheet remains far below these estimates, suggesting that sea level rise associated with Greenland glacier dynamics remains well below the low-end scenario 9.

We find that the 2-D sea level reconstruction shows spatial trend patterns similar to the one observed during the altimetry era. A similar analysis is performed with 20th century coupled climate model runs with complete external forcing i. Our sampling of a large population of glaciers, many of which have sustained considerable thinning and retreat, suggests little potential for the type of widespread extreme i.

Andresen et al, Nature Geo. Results suggest that in the tropical Pacific, sea level trend fluctuations are dominated by the internal variability of the ocean—atmosphere coupled system. In Greenland, this work assumed ice-sheet—wide doubling of glacier speeds low-end scenario or an order of magnitude increase in speeds high-end scenario from to Our objective is to investigate whether this yr-long trend pattern was different before the altimetry era, what was its spatio-temporal variability and what have been its main drivers.

For that purpose, we have computed sea level trend patterns over successive yr windows i. In this study we focus on the sea level trend pattern observed by satellite altimetry in the tropical Pacific over the — time span i. Changes on fast-flow marine-terminating glaciers contrast with steady velocities on ice-shelf—terminating glaciers and slow speeds on land-terminating glaciers.

We try to discriminate the respective roles of the internal variability of the climate system and of external forcing factors, in particular anthropogenic emissions greenhouse gases and aerosols.

Regionally, glaciers in the northwest accelerated steadily, with more variability in the southeast and relatively steady flow elsewhere.

Our result is consistent with findings from recent numerical flow models Earlier research used a kinematic approach to estimate upper bounds of 0. The same behaviour is found in multicentennial control runs of the coupled climate models. The pattern appears to have fluctuated with time with a characteristic time scale of the order of 25—30 yr.

Observed acceleration indicates that sea level rise from Greenland may fall well below proposed upper bounds. Finally, our observations have implications for recent work on sea level rise. Voici une des figures importantes de cet article: While our analysis cannot rule out any influence of anthropogenic forcing, it concludes that the latter effect in that particular region is still hardly detectable.
