UPDATE: A new set of data has been published. But there is still a value in the missing column. 0.01597 million sq km.

The updated graph:

I have been a bit worried about the deep deep dive in Antarctica Sea Ice Extent.

It appears to be a processing or sensor error. As of today the NSIDC data confirms it.

The table of data on the right of this image is the last 5 days. The data does have a value in the Missing column – 1.97873 million sq km.

The Missing column is usually empty. Sometimes it takes NSIDC a couple of days to sort things out.

This is a chart of the number of daily records and 2nd,3rd etc.  2014 now has more daily records (First) than any other year.

2014 is in 3rd place for top 5 … but it is only July 8. 180 days to go in the year.

There are no daily records from before 2007!

Many AGW true believers dismiss “Global Sea Ice” as an unimportant metric. I’m guessing that in a couple of days it will become important to them.

If I was an alarmists I would suggest that at the current rate of increase, by 2100 Antarctica will be completely inaccessible by ship.

But I’m not. I do wonder if the the spike in 1979 is an artifact of the satellite at that time, or if it is where we are now (remember the area to the left of 1979 just wasn’t recorded so we don’t know what it really looks like) and once the AMO cools Antarctica Sea Ice Extent will shrink and the Arctic will grow.
