Strong Recovery In Multi Year Arctic Sea Ice Continues

April 14, 2015

By Paul Homewood  




I mentioned a couple of weeks ago we have been witnessing a strong recovery in Arctic sea ice volume and thickness in the last three years.

This is due to the build up of multi year ice in recent years. I have been waiting for NSIDC to publish their Ice Age chart, which they have now done. (There is no link, as they have not released it publically yet – they have emailed it to me).




As can be seen, all categories of multi year ice have increased since last year, apart from the 4-year percentage. Perhaps most significantly, 5-year and over ice has strongly recovered from its low point in March 2012.

The 2012 figure, of course, reflected the large amount of ice lost in 2007 and 2008.

With the large increase in 3 and 4-year ice in the last couple of years, there is a strong foundation for a continued increase in 5-year ice in the next two years.

    no surprise to me

    I understand satellites have been measuring Arctic sea ice since the early 1970’s, but 1979 was chosen because it was a high point in Arctic Sea Ice and thus a reduction from this level was almost guaranteed. Is there any truth in this, a. that there is a longer history of measurement and b. 1979 was the high point.

      Correct. If they start that graph in 1975 there would be more ice now than then.

      Cherry picking 1979 is a conveni eco con job

    Paul there must be some fuming zealots out there with all the factual source data that you represent in your reports, as it comes from ‘the horses mouth’ leaving them no leeway to fabricate any criticism. Interesting about the 1975 / 1979 starting points
    Have been learning a lot over the last 3 or more years, but just leads to being even more disillusioned and cynical. Like many I trusted organisations like the BBC MetO etc had morel Integrity
    Not anymore

      I downloaded the 1990 IPCC report. It has a chart of satellite Arctic sea ice that begins in 1974. It shows 1979 with 2 million Sq KM more sea ice than 1975. That chart properly attributed to the IPCC is damming evidence of the misinformation we get from the warmists.

    I see yahoo news has a story running now that says we are now experiencing rapid warming. Whats going on? Cooked books? Record high antarctic sea ice doesn’t seem like rapid warming to me.

    For some strange reason you neglect to mention that the NSIDC also recently reported that:

    “The monthly average Arctic sea ice extent for March was the lowest in the satellite record”

    Here’s the link:

    So the Bering and Barents Seas aren’t in the Arctic either?
