In the case of the Arctic sea ice, which is entirely on top of the ocean, this means that the warmer waters are eating away at the ice from beneath it.<BR/><BR/>Something else that is going on is that since the ice is cracking up sooner, the warm water underneath is coming into contact with the extremely cold air above the cracks, and this is causing water vapor to form and flow upwards -- you can see this by looking for the odd-shaped, darker-gray, cloud-type patches in the black-and-white, IR, satellite images. Regular clouds mostly appear white.<BR/><BR/>I assume that this is just one way in which the air above the Arctic is heating up.<BR/><BR/>People can say whatever they like about Greenland once being warmer and greener, but so far as we know, the Arctic has not been ice free at any time during the sojourn of human beings on this planet.<BR/><BR/>The process is different at the South Pole because the ice sits on bedrock so it is not possible for warm ocean water to circulate under it. (Of course, it can circulate under the ice shelves.) Thus, the heat first causes more snow (as all the models have predicted), and the heat released has gone to the troposphere, where there has been the greatest warming recorded.<BR/><BR/>If the ocean buoys are not showing an average increase for the past 4 years, then the heat is going somewhere else. Eventually, they will figure out where it went.Anonymoushttps://www.blogger.com/profile/06411884167270802998noreply@blogger.comtag:blogger.com,1999:blog-579549341020421678.post-54316036815905688332008-04-13T09:31:00.000-05:002008-04-13T09:31:00.000-05:00"Red indicates ice that is only one year old.

Notice that in February of this year there was very, very little older ice, and it was mostly located just north of Greenland and the northern islands of Canada. One-year-old ice now represents a good 70% of the coverage ..."</I><BR/><BR/>Given that so much of the arctic was free of ice last August, as was widely reported, wouldn't we expect much of the current ice in the arctic to be 1 year old or less?Anonymousnoreply@blogger.com
