ice-sheet maxima is also important for
understanding ice-sheet sensitivity to regional
and global climate change, as well as in
establishing ice-sheet–climate feedbacks.

some of the other Great Lakes — fell well

found to be underestimating the extent and
changes in GIS elevation and area; our findings
may help to improve the ability of models to
reproduce the GIS response to Holocene

39. “ Historical records indicate that Arctic sea-ice
extent has been declining since the late 19th
century. Although this decline was
accompanied by multidecadal oscillations, the
accelerated ice loss during the last several
decades lead to conditions not documented in

✓ shows us how critical landscapes and natural resources
have been affected by climate change in the past
✓ gives us a broader perspective on contemporary
environmental and resource issues
✓ provides a major contribution to international initiatives
that assess the dynamics of the global climate system
