Opportunities and challenges from melting Arctic icecap discussed at CEOI Challenge Workshop

16 October 2013

Observations from satellites (IceSat and CryoSat 2) have shown that the annual minimum of Arctic sea ice cover is shrinking, both in extent year on year, and possibly in thickness and volume. If warming trends continue, as is likely, we may see ice-free summers in the Arctic within the next decade.

NASA supercomputer generates closer look at future climate conditions in U.S.

10 September 2013

Global models of the climate system are now the foundation for many important climate studies, but they typically show climate changes at very large geographic scales on the order of 100 to 250 kilometres. Some data sets have scaled that down to about 10 kilometres, but even these make it difficult to analyse climate change impacts on a local or regional scale.
