|a The observed acceleration of outlet glaciers and ice flows in
Greenland and Antarctica is closely linked to ocean warming,
especially in the subsurface layer1–5. Accurate projections of
ice-sheet dynamics and global sea-level rise therefore require
information of future ocean warming in the vicinity of the
large ice sheets. Here we use a set of 19 state-of-the-art
climate models to quantify this ocean warming in the next two
centuries. We find that in response to a mid-range increase
in atmospheric greenhouse-gas concentrations, the subsurface
oceans surrounding the two polar ice sheets at depths of
200–500m warm substantially compared with the observed
changes thus far6–8. Model projections suggest that over
the course of the twenty-first century, the maximum ocean
warming around Greenland will be almost double the global
mean, with a magnitude of 1:7–2:0 [degrees]C. By contrast, ocean
warming around Antarctica will be only about half as large as
global mean warming, with a magnitude of 0:5–0:6 [degrees]C. A more
detailed evaluation indicates that ocean warming is controlled
by different mechanisms around Greenland and Antarctica.We
conclude that projected subsurface ocean warming could drive
significant increases in ice-mass loss, and heighten the risk of
future large sea-level rise. |
