30 (2): Sea ice in the polar regions
Understanding past, present, and future changes in Arctic and Antarctic sea ice is crucial to understanding a wide range of interconnected impacts. This special issue contains articles describing novel proxies and reconstructions of sea ice at a range of timescales from both poles, highlighting some state-of-the-art knowledge in this field.
