    Atmospheric circulation patterns in August helped spread out sea ice, slowing ice loss in most regions of the Arctic. NSIDC scientists expect to see the minimum ice extent for the year in the next few weeks. While this year's minimum ice extent will probably not reach the record low of 2007, it remains well below normal: average ice extent for August 2009 was the third-lowest in the satellite record. Ice extent has now fallen below the 2005 minimum, previously the third-lowest extent in the satellite record.

    So now it's not melting too fast since a few weeks ago you said it was "the" lowest on record.

    Again this proves what exactley? We all get at this point that you want to try to prove to all of us it is getting warmer, with your daily updates of various whether phenomenon and events. It means NOTHING in terms of mans effect on it.

    Again we get that it is getting warmer, but man's contribution to your dreaded CO2 now dubbed a polutant (really amazing considering said 'polutant' is essential to life on the planet) is statistically insignifant. Man's contribution to CO2 in the atmosphere is approximately 2 - 5 percent of this TRACE gas.

    Salt is absolutely essential for life. Now that we have established that, why don't you just down a quart of it and see what that does for you. There are many things that are essential for life which in too large a dose, can destroy life.

    The warming that we are seeing today is the result of the GHGs that man is adding to the atmosphere. Every scientific society, every national academy of science, and every major university in the world states that. The physics of it was established in 1896. And the predictions of warming made then have come to past.

    Arctic Sea Ice News & Analysis


    Further reading

    Three papers published in the past month have added important insight to our understanding of Arctic warming and sea ice decline. Elizabeth Hunke and Cecilia Bitz show that improved models can now reproduce the changes in sea ice extent and sea ice age that have occurred in the last 30 years. Ron Kwok and Drew Rothrock combine satellite data and submarine measurements to show an astonishing decline in sea ice thickness over the last 50 years. And Darrell Kaufman and colleagues show that recent warming has reversed a 2,000-year cooling trend in the Arctic, and that this cooling was what would be expected from slow changes in Earth's orbit. The recent changes cannot be explained by these natural factors.

    Salt does not "destroy life" ... it does prevent some plant life from growing, and some life forms need much more than we do. Saline is one of the building blocks, so is carbon. Without carbon and saline, all life would die.

    First simply saying ALL this or ALL that agree is a bit absurd. Some do some don't. Some do believe because they think the evidence is there, many 'believe' for financial gain.

    To put it to the question what you are saying is that ALL (except for these nobodies of course Global Warming:A Chilling Perspective ) these bodies believe that the 2 - 5% contribution to GHGs that man contibutes is a significant portion of the warming we're seeing, correct? That the 1.4 degree fahrenheit increase we have seen in the last 100 Years is mostly due to man?

    Interesting stuff, but it doesn't prove anything. People of your ilk (non-scientist, global warming alarmists) don't do the actual scientists any favors. First, unless you are a member of all of those sites you posted thus allowing you to read the FULL test of each of the links you provided you certainly can't speak to the conclusions they made. I'm not sure how the person who write for the 'revered' ARCTIC SEA ICE NEWS can either. He concludes normal patterns of orbit can not account for the increased rate of melting. Not sure how he can do that considering none of the links provided make that conclusion (good scientists rarely conclude anything, rather they report observations). They simply state sea ice melting has accelerated.

    These are the nobodies at "Global Warming, a Chilling Perspective". And, indeed, they are nobodies.

    Description This site totes itself as a learning resource. It is a science based website that has many different links to different earth science issues (pages they maintain themselves). They are private and have a "humans have not caused any problems - it is just a cycle" sort of view on climate change. It sucked. Bad.
    Orientation/
    Premise I couldn't discern any political premises or orientation in the website - they claim to be an educational website.
