Ice model emulator
State-of-the-art ice-sheet models are computationally expensive to run. A single simulation may require hours to days of computing time, making it difficult to explore uncertainties in future climate …

Ice streams and ice sheet sensitivity
Ice streams can display oscillatory and even chaotic behaviour. Does the internal state of an ice stream affect how the ice sheet responds to anthropogenic warming? And if so, how predictable is …

East Greenland ice core dust record reveals timing of Greenland ice sheet advance and retreat
Grains of dust in an ice core illustrate how fast a landscape is covered with ice after an ice age sets in.

Optimistic and over-confident ice sheet projections in AR5
Take away message: The graph on the right shows that AR5 process based ice sheet projections are optimistic and over confident when compared to views of ice sheet experts. To be fair they do mention a …

Relative importance of mass and volume changes to global sea level rise.
We examine the relationship between 50-year-long records of global sea level (GSL) calculated from 1023 tide gauge stations and global ocean heat content (GOHC), glacier and ice sheet melting. The …
