No NSIDC Sea Ice Data For 2 days

There have been no updates to NSIDC Sea Ice Extent for two days. Data is usually found here and here.

I am guessing it is because of the recent intense solar flares and activity.

NSIDC and Antarctica

Filed under: Antarctic Sea Ice,NSIDC — sunshinehours1 @ 10:39 AM

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.

Government Shutdown Stops Sea Ice Data Updates From NOAA

Filed under: Antarctic Sea Ice,Arctic Sea Ice,NOAA,NSIDC — sunshinehours1 @ 9:39 AM
Tags: , , ,

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.

Best regards,

NSIDC is Broken Due to Boulder Flooding

The source of most of the the data I use for Antarctic and Arctic Sea Ice Extent is NSIDC.

They are not updating or providing data until Monday because of the flooding in Boulder Colorado.

Less Fresh Water in the Arctic and More Rainfall in Australia Leads To Lower Sea Level and Less Ice?

Filed under: Arctic Sea Ice,Australia,Mockery,Morons,NSIDC — sunshinehours1 @ 2:31 PM
Tags: , , , ,

Could massive amounts of rainfall in Australia have deprived the Arctic of fresh water so there was less sea ice?

NSIDC:  “Water from the Pacific Ocean and several rivers in Russia and Canada provide fresher, less dense water to the Arctic Ocean. So the Arctic Ocean has a layer of cold, fresh water near the surface with warmer, saltier water below. This cold, fresh water layer typically allows more ice growth in the Arctic than the Antarctic.

NCAR: ” when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably.”

Antarctic Sea Ice Extent – 6th daily record for 2013

Filed under: Antarctic Sea Ice,NSIDC — sunshinehours1 @ 7:53 AM
Tags: ,

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.

Year No of Daily Records
2010 129
2008 128
2006 29
2012 24
2007 21

2000 6

Updated/Corrected: Arctic Sea Ice Extent Average for 2012 is now higher than 2007 (NSIDC)

Filed under: Arctic Sea Ice,NSIDC — sunshinehours1 @ 10:51 AM

UPDATE: My apology. The original post was wrong.

What I did (in a hurry) was post the Extent for day 290, not the mean of the extent up to day 290.

Sorry.

The correct data is:

The mean for 2012 up to day 290 = 10.5267 million sq km
The mean for 2007 up to day 290 = 10.52817million sq km

2012 is still lower than 2007, but only by 1,468.4 sq km. A statistical tie.

If I had waited one more day and had done it right, the conclusion of my original post would have been right.

But it wasn’t.

However, the mean for 2011 up to day 290 is 10.522 million sq km.

Which means 2012 has now averaged 4,633.3 sq km more ice than 2011 thanks to normal extent earlier in the year.

Original Post Starts Here:

Using NSIDC data (to day 290):

The mean of Arctic Sea Ice Extent for 2012 = 5.78274 million sq km
The mean of Arctic Sea Ice Extent for 2007 = 5.74562 million sq km

The average Arctic Sea Ice Extent for 2012 is now 37,120 sq miles higher than 2007.

NSIDC Ignored Antarctica in 2006 Too

Filed under: Antarctic Sea Ice,Mockery,NSIDC — sunshinehours1 @ 7:49 AM
Tags: , , , , ,

Antarctic Sea Ice Extent set an all time record in 2012. The previous record was set in 2006. In 2006 there were 30 days where the ice extent was over 19 million sq km. That record has not been broken and was 9 days more than the previous record holder (1998).

So what did the NSIDC have to say about it in 2006?

Nothing.

They mentioned the Arctic a lot. And Al Gore’s movie. And that there was going to be an open house. But they ignored Antarctica. If they were scientists and not propagandists shouldn’t they be interested in both poles and maximum records too?

Antarctic Sea Ice Extent Still Another Daily Record – 23rd for 2012

Filed under: Antarctic Sea Ice,NSIDC — sunshinehours1 @ 9:46 PM
Tags:

Antarctic Sea Ice Extent set another daily record yesterday (day 276 – 2012 Oct 2.). Sea ice extent was 19.17826 million sq km.

The previous day 276 record was 19.15764 million sq km and occurred on 2005 Oct 3.

This is the 23rd daily record and 12th day in a row that is a record for the day.

 

NY Times Dishonestly Shills for NSIDC Antarctic Deniers

A few days I asked the question about the record Antarctic Sea Ice Extent in 2012 “Anyone wonder why NOAA isn’t making a fuss about this?”

One caveat is that I should have said NSIDC instead of NOAA (NOAA does partially fund NSIDC).

Today Justin Gillis took a cheap shot at bloggers (h/t Tom Nelson) and said:

“The National Snow and Ice Data Center uses a five-day moving average to track such matters, and always waits a few days before announcing a minimum or maximum in sea ice at either pole. That is to make sure the low or high point for the year has really been reached, given that sea ice can change abruptly in response to winds and other factors. The five-day averaging also helps smooth out small errors in the satellite tracking data.

.

This longstanding practice has been explained publicly many times, but that has not stopped climate-change contrarians from asserting that the snow and ice center had been trying to hide this year’s record in Antarctica by supposedly failing to make any announcement.”

I checked. The Arctic record was broken on the August 24th and NSIDC waited 3 days to call a news conference for the media on the 27th,

The Antarctic Extent record was broken on September 24th.  I wrote about the Antarctic Ice Area coming close to the record on  September 24th, but  I was 5 days late writing about the Antarctic Ice Extent breaking the record (NSIDC uses Extent and I had not come across the NSIDC data)  and did not post until September 29th.

So of course NSIDC held a news conference on September 27th to announce the new record … didn’t they?

No. No news conference.

Obviously there was a media advisory on the 27th.  Nope.

If you go the press page for NSIDC you will see that Antarctic Ice Extent record is not mentioned until October 2nd, 2012.

Justin Gillis and the NY Times owes a lot of bloggers an apology.
