    The IPCC tends to be too conservative in various aspects of climate science, from sea level to Arctic sea ice depletion

    http://www.agu.org/pubs/crossref/pip/2011JC007110.shtml

    The core finding that observations have trending downward faster than models predict isn't a new finding, but the new study provides an explanation.

    Looks like the paper was in press at the time I posted it. Thus, the "pip" in the original URL.

    Study: Arctic Temperatures Highest in 44,000 Years
    October 25, 2013 ~ Average summer temperatures in the eastern Canadian Arctic are higher than they have been in at least the past 44,000 years and perhaps higher than at any time in the past 120,000 years, according to a new study.

    And why should we be caring about this when its happened many times before ? Antarctica has actually been breaking records for ice coverage and volume lately but that doesnt get reported., It doesnt sell because it isnt panic worthy

    Just to put todays polar fluctuations into some kind of realistic historical context

    In short neither pole shows variations in level nor rate of change that are outwith natural variation . Today is nothing special

    This is why models are wrong.

    The IPCC models assume that temperature drives arctic sea ice. This has been proven false in the last few years. Arctic winds have been driving sea ice in the last decade. The arvtic has proven way more responsive to wind than temperature.

    Yes maps are models so they must be wrong. Lets get rid of them.

    At least it was appropriate to your post so I will take that as self-assessment. LOL

    No one wants to hear you preach. Either answer why the winds are driving ice melt and not temperature or leave.

    So you have no idea how to address the wind issue then.

    The arctic is far more sensitive to factors other than ambient temperature.

    Ocean currents, wind direction, wibd magnitude, black carbon, all have a far greater effect in arctic ice than temperature.

    So is the arctic more responsive to temperature or wind?

    You dont have an answer do you?

    That is why you should leave.

    Derpa-doodle-doo . . . time to wake up, throw the tea overboard, FINALLY, and smell that coffee.

    I recommend 1. Peet's 2. 'buck's

    I also brew the stuff.

    Since perennial ice is melting, and humidity is up, wherever the warming isn't wrecking everything is where ice may build up, and that is NOT in every area, of Antarctica, which is affected, by warming currents.

    Antarctica is continually the subject, of denier rants, after almost all the other land-locked glacial areas, in the world are receding.

    Whoop. Antarctica.

    Just wait, until the sea finishes warming up, so jellyfish are the top predator, and algae gets on everything, unless cold currents manage to spill acidic water, on everything and corals and shellfish.

    Considering what they've got wrong so far, being conservative is probably a good thing.
