Change in future climate due to Antarctic meltwater.

Meltwater from the Antarctic Ice Sheet is projected to cause up to one metre of sea-level rise by 2100 under the highest greenhouse gas concentration trajectory (RCP8.5) considered by the Intergovernmental Panel on Climate Change (IPCC). However, the effects of meltwater from the ice sheets and ice shelves of Antarctica are not included in the widely used CMIP5 climate models, which introduces bias into IPCC climate projections.

Reconstructing surface ocean circulation with I time series records from corals.

The long-lived radionuclide I (half-life: 15.7 × 10 yr) is well-known as a useful environmental tracer. At present, the global I in surface water is about 1-2 orders of magnitude higher than pre-1960 levels.
