Now that NSIDC is publishing data again I thought I would post two graphs comparing JAXA MASIE and NSIDC.
I’m doing it for Arctic and Antarctic (but MASIE has no Antarctic data)
Normally in the Arctic JAXA and NSIDC are very close only at the minimum … but now they are very close.
And in the Antarctic they might as well be doing just one they overlap so much.
UPDATE: Antarctic and Arctic has been published. MASIE is still one day behind.
There have been no updates to NSIDC/NOAA Antarctic Sea Ice Extent for three days. Arctic Data is late for today. And MASIE did update their data, but it is one day older than it should be.
Update: Below I noted that “there could have been one more record”. I was right. A 3rd All-time Record for Antarctic Sea Extent was set.
On October 3rd NSIDC put out a press release on the Arctic/Antarctic Sea Ice.
Let us take a look at the comments on Antarctic Sea Ice.
“As the Arctic was reaching its minimum extent for the year, Antarctic sea ice was reaching record high levels, culminating in a Southern Hemisphere winter maximum extent of 19.47 million square kilometers (7.52 million square miles) on September 22. ”
Wrong. The 2012 record was 19.47 million sq km on September 22, 2012. The 2013 record was 19.51234 million and was set on September 14th. Then the record was broken again with 19.51394 million sq km on September 21, 2013.
And looking at the graph until October 1st (when the shutdown ended the data ) there could have been one more record.
“The September 2013 monthly average was also a record high, at 19.77 million square kilometers (7.63 million square miles) slightly higher than the previous record in 2012.”
Wrong. The September 2013 monthly average was 19.35 million sq km which was 100,000 sq km higher than the September 2012 average of 19.25 million sq km. ”
One or two scientists claim it is because of the wind. But it could be the AMO and/or ocean temperatures. I think the wind claim is just an excuse.
“In contrast to the sharp downward trend in September Arctic sea ice, Antarctic September sea ice has been increasing at 1.1 percent per decade relative to the 1981 to 2010 average.”
And the anomaly at maxium was 900,000 sq km above the 1981-2010 average.
“The tiny gain in Antarctica’s ice is an interesting puzzle for scientists,” said NSIDC lead scientist Ted Scambos.
Tiny Gain? The September average in 1986 was 17.69 million sq km. In 2013 it was 19.35 million sq km. That is 1.6 million sq km higher!
“The rapid loss of ice in the Arctic should be ringing alarm bells for everyone.”
If it wasn’t for the August 2012 Cyclone. The trend would be up from 2007.
There were no NSIDC sea ice updates today. I emailed NSIDC to ask why and got this prompt and polite reply.
“Thank you for contacting the National Snow and Ice Data Center.Because our data provider, the National Oceanic and Atmospheric Administration (NOAA), has shut down the data stream as part of the government shutdown, we are temporarily unable to update the product.
I apologize for the inconvenience.

Day 73 (March 14) had Antarctic Sea Ice Extent set its 8th daily record – the 5th in a row.
2013 broke the old record from 2008 by 32,420 sq km. 2008 had broken the previous record (2001) by 240,070 sq km.
2008 was an amazing year for Antarctic Sea Ice. Did you know that on day 1 in 2008, the old record was broken by 1,391,120 sq km which had occurred in 1996?
Too bad the NSIDC “scientists” ignore Antarctica. It would have made a great story.
Day 71 in the Antarctic was another daily record for Sea Ice Extent (most ice on this day). That makes 6 for 2013 (corrected from 2003 typo). And the 3rd day in a row.
There are only 7 days where a daily record exists from before 2000. 345 records are from 2006 to 2013.
NSIDC has a dedicated page to Arctic Sea Ice. And one for Greenland. But no page dedicated to the Antarctic. That makes them propagandists, not scientists.
