The extent of global sea ice is more than 1 million square kilometers below the previous record for the current date. This year is particularly a result of the anomalous Antarctic.

@ZLabe The thing people neglect in looking at the sea ice figures is that the absence of ice cover itself directly affects the ecology and physical dynamics of the region. Regardless of what you think about climate change and net ice sheet growth, changes in the amount of sea ice have profound effects.
