From 1974 to 1976, an unexpected large hole appeared in the Weddell Sea winter sea-ice cover, a consequence of ocean heat carried to the sea surface by convection. This may have been a window to the past, as model analysis suggests anthropogenic climate change will diminish the chances of a repeat performance.
