Antarctic Sea Ice Sets New Record For Jan 31st

Written by Paul Homewood

Antarctic sea ice extent continues to break records. Extent at 31st January, of 4.540 million sq km, beat the previous record set in 2008. This is 26% higher than the climatological average for this date of 3.598 million sq km.

Antarctic sea ice


On average, Antarctic sea ice reaches minimum on 20th February, about a month earlier, relatively speaking, than the Arctic. It is likely then that we will see a new record high minimum set this month. The current record was set in 2008, with 3.691 million sq km.

Meanwhile, global sea ice area is normal.

    DVV seems to get his Arctic and Antarctic mixed up. The Arctic sea ice extent has declined over the past 40 or so years while the Antarctic has increased. Given Antarctica is bigger, overall there is slightly more sea ice. This doesn’t mean much in itself because there is also land ice and I have no idea whether that has increased or decreased or stayed much the same.

    It seems sea ice is just another proxy for the ongoing fight between alarmists and denialists or whatever they are each called by the other side.

    It seems to me we should stop posturing on the basis of what is selective data.

    We need everyone to admit that there is climate change and always has been climate change caused by a combination of factors the relative proportion of which has varied from time-to-time (sunspots, solar flares, volcanic eruptions, meteorite impacts, the wobble of the earth’s axis, continental drift).

    If it is true that anthropogenic causes are now paramount (a hypothesis that is formed from post-hoc observations and forward projections based on models that may or may not be accurate), then it is probably also true that economic and social progress leading to technological innovation over the next fifty years will provide a much cheaper solution to this impact at a lower overall cost than taking action now.

    Having partaken as a society in the benefits of the industrial age, we should not deny it to the rest of the world by making the cost of energy higher. The market will move to renewable energy when its cost (through innovation especially in solar cells and the utilisation of the sun’s vast energy) drops below the cost of fossil fuels. It is economic and social vandalism to create poverty traps by mandating the use of a less efficient means of energy use. Shrinking the economy does not help anybody.

    DVV. I went to the site you referenced and clicked on ‘Antarctic’. The sea ice extent graph for the past 30 years jumps up and down, the site kindly provides a trend line which is positive at ” 3.7% (+/-4.1) per decade “.

    Ahhh, This graph above shows the summer sea ice extent. Sea ice extent normalized for seasonal variation, since 1979 shows a significant total decline in total sea ice.

    The graph is being misrepresented.

    Thanks, John, for your blog.

    Missouri continues to suffer ice storms, bitter cold, and loss of faith in our government’s AGW tale.

    Yet not a single member of the consensus science community has challenged the data in Figures 1-3 (pages 17-29 of Chapter 2 of my autobiography) or the conclusion that the Sun’s core is a pulsar remnant from the birth of the solar system.

    Is the United States National Academy of Sciences like “a generation of vipers,” a private, self-perpetuating organization that reviews the budgets of federal agencies for Congress and thus guides research, with little or no limit on conflict of interest?
