2007 Sea Ice Post Mortem

2007 Sea Ice Post Mortem“. Lately it’s been embarrassing for denialists to talk about the 2010 Arctic Sea Ice Extent, so the indefatigable Steven Goddard tries to recast various denialist comments about the record low 2007 season and misrepresent the remarks of professional climatologists from the time.

First, he tries to pretend that ice volume was what really counted in 2007, not ice extent. Actually, they fought pretty hard against that metric back then. Too bad the ice volume has been steadily declining.

Next, he tries to tie the expert’s ice predictions to newspaper speculations. That’s just plain dishonest.

It seems that no progressive loss of Arctic sea ice will make Steven admit he’s spitting in the wind unless the Arctic Ocean is completely ice-free. Whenever his ‘nothing to worry about’ BS starts getting shaky, he simply moves the goalposts. The only thing thinner than the Arctic sea ice is Steven’s own skin.

One thought on “2007 Sea Ice Post Mortem

  1. POLAR AMPLIFICATION CONTINUES………. Steve Goddard argues that there are some limits to sea ice changes because Arctic summers have not warmed up. But warmer temperatures in other seasons are now producing thinner ice, year after year. And wouldn’t a resulting warmer summer be just the expected consequence of increased, and prolonged, areas of open water?

    His argument about the consequences of colder temperatures at the pole doesn’t seem convincing. When there’s less ice in the the Arctic overall, what would keep some of it at the pole?

    IN OTHER’S WORDS……….”Goddard appears not to understand that Arctic summer temperatures don’t get much above zero degrees Celsius because all the heat’s going into melting ice. As scientists might put it, the temperature is ‘constrained’ by the melt, and so will only show dramatic increases in summer when all the ice is gone.” (etc) HotTopic (June 10, 2010)

    ON THIN ICE………. (VOLUME)….. NASA Press Release (July 7, 2010)….. “Arctic sea ice thinned dramatically between the winters of 2004 and 2008…about 7 inches a year, for a total of 2.2 feet over four winters.”

    Multiyear ice area is down 42% over the same period.
    Per PIOMAS, sea ice volumes have continued to decline in 2009 and 2010. May 2010 has the lowest May volume in their records.

    …..(EXTENT)….. NSIDC Press Release (Oct 6, 2009)

    “…the 2009 minimum sea ice extent was the third lowest…The past five years have seen the five lowest Arctic sea ice extents ever recorded.”

    “…Arctic sea ice in September is now declining at a rate of 11.2 percnt per decade and in the winter months by about 3 per cent per decade.”

    80% GONE BY 2016?………. Climate Progress discusses Maslowski, his presentation and his prediction, here.
