Sentences with phrase «term sea level rise projections»

The findings do not significantly alter short - term sea level rise projections, but they mean that we may need to prepare for larger amounts of long - term sea level rise than previously thought.

Not exact matches

«The information will be a critical complement to future long - term projections of sea level rise, which depend on melting ice and warming oceans.»

The conclusion that the Greenland ice sheet melting was significantly enhanced by the increased N. Hemispheric insolation during the Eemian affects projections of future (near term) sea level rise insofar as Greenland melt contributed to the Eemian sea level rise.

Anthropogenic carbon emissions lock in long - term sea - level rise that greatly exceeds projections for this century, posing profound challenges for coastal development and cultural legacies.

In more recent years, even as forecasts of global sea - level rise have been notched up, most projections have not taken into account the possibility of a significant, near - term ice loss from the West Antarctic.

Scientists are working to understand how unstable the ice sheets are, and how much additional sea level rise we could see over the current projections, particularly for the short - term (like in the time frame your kids will see).

Such solecisms throughout the IPCC's assessment reports (including the insertion, after the scientists had completed their final draft, of a table in which four decimal points had been right - shifted so as to multiply tenfold the observed contribution of ice - sheets and glaciers to sea - level rise), combined with a heavy reliance upon computer models unskilled even in short - term projection, with initial values of key variables unmeasurable and unknown, with advancement of multiple, untestable, non-Popper-falsifiable theories, with a quantitative assignment of unduly high statistical confidence levels to non-quantitative statements that are ineluctably subject to very large uncertainties, and, above all, with the now - prolonged failure of TS to rise as predicted (Figures 1, 2), raise questions about the reliability and hence policy - relevance of the IPCC's central projections.

None of these could have been caused by an increase in atmospheric CO2, Model projections of warming during recent decades have greatly exceeded what has been observed, The modelling community has openly acknowledged that the ability of existing models to simulate past climates is due to numerous arbitrary tuning adjustments, Observations show no statistically valid trends in flooding or drought, and no meaningful acceleration whatsoever of pre-existing long term sea level rise (about 6 inches per century) worldwide, Current carbon dioxide levels, around 400 parts per million are still very small compared to the averages over geological history, when thousands of parts per million prevailed, and when life flourished on land and in the oceans.
