Observed ice-sheet losses track the upper range of the IPCC Fifth Assessment Report sea-level predictions, recently driven by ice dynamics in Antarctica and surface melting in Greenland. Ice-sheet models must account for short-term variability in the atmosphere, oceans and climate to accurately predict sea-level rise.

Environmental Science
CryoSat-2 satellite altimetry is used to produce direct measurements of Greenland's runoff variability, based on seasonal changes in the ice sheet’s surface elevation, which shows runoff is now also 60 % more variable from year-to-year as a consequence of large-scale fluctuations in atmospheric circulation.

Accelerating changes in ice mass within Greenland, and the ice sheet’s sensitivity to atmospheric forcing
- M. BevisC. HarigThomas H. Nylen

Environmental Science, Geology
The spatial pattern of accelerating mass changes reflects the geography of NAO-driven shifts in atmospheric forcing and the ice sheet’s sensitivity to that forcing, and it is inferred that southwest Greenland will become a major future contributor to sea level rise.

This work combines satellite observations of its changing volume, flow and gravitational attraction with modelling of its surface mass balance to show that the Antarctic Ice Sheet lost 2,720 ± 1,390 billion tonnes of ice between 1992 and 2017, which corresponds to an increase in mean sea level of 7.6‚¬3.9 millimetres.

Environmental Science
This work uses extreme value theory to combine sea-level projections with wave, tide, and storm surge models to estimate increases in coastal flooding on a continuous global scale and finds that regions with limited water-level variability, i.e., short-tailed flood-level distributions, located mainly in the Tropics, will experience the largest increases in flooding frequency.
