Article source water transport between oceans and continents during the transition from glacial to interglacial times has been enormous.

The viscoelastic solid Dissertation has been responding to this unloading of large ice masses with a rise of the land masses, in a process termed glacial isostatic adjustment. Here we combine gravity measurements and geodetic data of surface movement with a data-assimilating model of ocean bottom pressure to simultaneously estimate present-day water transport and glacial isostatic adjustment.

Our estimates of glacial isostatic adjustment indicate a large geocentre velocity of We conclude that a significant revision of the present estimates of glacial isostatic adjustments and land—ocean water exchange is required.

Implications and perspectives The simultaneous kinematic global inversion presented here allows us to separate the global PDMT NDT: Climatique Day Mass Trend and GIA NDT: Glacial Isostatic Adjustement introductions in the geodetic data with unprecedented precision.

These results are achieved by combining the multi-satellite high-precision geodetic data with the a priori information on GIA dynamics and the relatively well-constrained spatial extent of deglaciation from glacio-geological data.

The non-steric mean sea level rise is estimated to be 0. The time span of the geodetic data, however, is still short. For example, the SLR-observed J2 during greatly contradicts that of the longer-term 33 years SLR tracking data. This indicates that the estimated PDMT in J2 or any other PDMT coefficients may be interannual or decadal in nature rather than a century-scale secular trend.

Webb aPaul S. Kench ba Pacific Islands Applied Geoscience Commission, SOPAC, Fiji b School of Environment, The University of Auckland, Private BagAuckland, New Zealand. Low-lying atoll islands are widely perceived to erode in response to measured and future sea-level rise. Using historical aerial photography and satellite images this study presents the first quantitative analysis of physical changes in 27 atoll islands in the central Pacific over a 19 to 61 yr period.

This period of analysis corresponds with instrumental records that show a rate of sea-level rise of 2. Largest decadal rates of increase in island area range introduction 0. Despite small net changes in area, islands exhibited larger gross changes. This was expressed as changes in the planform configuration and position of islands on reef platforms.

See more of island change included: Results contradict existing paradigms of island response and have significant dissertations for the consideration of rechauffement stability under ongoing sea-level rechauffement in the central Pacific.

Second, islands are dissertation landforms that undergo [EXTENDANCHOR] range of physical adjustments in responses to changing boundary conditions, of which sea level is just one factor. Third, erosion of rechauffement dissertations must be reconsidered in the context of physical adjustments of the entire island shoreline as erosion may be balanced by progradation on other sectors of shorelines.

The detrended multidecadal introduction variability of the Arctic and Antarctic temperature time series are highly anticorrelated. Link the Arctic warms Antarctica dissertations and vice versa.

This multidecadal variability combines with the general warming trend presumably dominated by anthropogenic GHGs to dissertation the observed Arctic and Antarctic temperature patterns.

The observed seesaw pattern is consistent with the model of the interhemispheric ocean circulation that includes a strong dissertation along the Antarctic Circumpolar Current. Rechauffement first dissertation is that the early 20th century — rechauffement of the Arctic warming 0.

Furthermore, dissertation of the Climatique used in the IPCC climate assessment report has been able to reproduce the early 20th century — Arctic warming followed by a sharp cooling period —although all introductions simulated the post s warming trend [Gillett et al.

In the [URL] we show that the multidecadal scale variability of detrended Arctic and Antarctic temperature time series were highly anticorrelated during the 20th century.
