Why The Antarctic Sea Ice Is So Low--It's Not All Climate Change

.... record record tropical sea surface temperatures ...

Not climate change related? The article is about why this year is so low compared to other recent years. Record years *always* have a lot of contributors, but a long term secular trend will lead to more records in one direction than the other. And the article points out very clearly that the Arctic is a different kettle of fish--a really shocking decline, such that there has been a Northwest Passage every summer for the last few years...for the first time in recorded history.

Sigh. Record years are *never* 'all climate change.' That is the nature of a record compared to other years nearby. Just like mean global temperature *always* hits a local maximum in El Nino years, minimum ice extent records will have a number of components. The thing to watch is the number of warm record extrema vs number of cool extrema. Warm records have been vastly outnumbering cold ones in the last 50 years.
