Just a short post today about sea ice trends at Antarctica, a place that global warming alarmists don’t like talki9ng about
For some reason, the Japan Meteorological Agency (JMA) doesn’t add a trend line to the annual minimum and mean sea ice extent plot for Antarctica.
So we’ve added these trend lines:
Data source: JMA
Minimum sea ice extent has remained steady over the past 4 decades. But both the mean and maximum sea ice extents have risen, meaning more ice at the South Pole.
More ice of course only forms when the temperature drops. Global warming has yet to reach the South Pole. This is one of the most inconvenient regions on the planet for the global warming alarmists.

I just hate these “inconvenient truths” . . . with no apologies to Al Gore.
Antarctica is possibly the most important place on earth regarding the long term evolution of climate. Antarctica is the “Grand Central Station” of the global Thermohaline Circulation of ocean currents at all depths.
Antarctica led the world into glacial termination and the start of the Holocene, and it will lead us back to glacial inception. This has probably already started.

Do you have any data to support this hypothesis?
I’m interested.
{ OK, I found some links above. }
Here are two papers showing thattermination of the last glaciation started with slow ocean warming around Antarctica about 20,000 years ago:

Thank you, I’ll try to digest all that when I have some idle time again.
Is climate change the reason that Antarctic sea ice has grown over the past 10 years? Between 2012 to 2014, it reached record-high extents each year during the winter. … Since the late 1970s, the Arctic has lost an average of 20,800 square miles of sea ice per year, while the Antarctic has gained an annual average of 7,300 square miles.

That’s all correct, but please keep in mind that you posted a link to an article dated… 2016.
Here is a comparison of Antarctic and Arctic sea ice extent anomalies (wrt the mean of 1981-2010) from 1979 till now:
If the article had been written 3 years later, the author probably would have written something different.
Btw: no idea what happened with that downunder ice in 2016!
But of course (and luckily) Antarctic sea ice nevertheless is recovering, and still experiences an upward trend, even if increasing far slower than its counterpart decreases in the North.

At least it’s remote and kept safely away from CA and NY readers. It would only make them confused and angry and require much backfilling with guest op-eds from political leaders to return them to their comfort zones—of ignorance.
If I was looking at the data presented, not knowing what it was measuring, my first reaction would not be about a general trend, but about the increase in variance. Even if this is accurately measured, what does it mean?
