Understanding the Arctic as a System

Arctic climate change: Alternative futures

While changes of sea ice and air temperature have received widespread media coverage, other changes in the cryosphere and the broader Arctic environment have been synthesized in recent assessment reports. A consistent pattern of change through the Arctic system has emerged. However, the future trajectory of the system is subject to various uncertainties, and human actions can alter this trajectory.

In this presentation we view future changes in the Arctic climate system over two time scales (near-term and longer-term). This framework allows us to illustrate how the key uncertainties change over time and to distinguish an adaptation timescale from the a mitigation timescale. Determining whether or not the Arctic system can be stabilized by existing international targets for global warming is a key issue for climate science.
