Sea ice in the climate system
Arctic sea ice is a sensitive indicator of climate change and changes to the sea ice cover can have potential implications for the Arctic region and beyond.
and/or observational records, and so cannot take into account changes in feedbacks and processes in the climate system as the ice cover declines. Therefore climate models remain our most robust tool for investigating future change. References Vaughan, D.G., et. al 2013: Observations: Cryosphere
