    According to this article, solar seems to play a very minor part in the present warming.

    Pubs.GISS: Abstract of Benestad and Schmidt 2009

    Benestad and Schmidt 2009
    Benestad, R.E., and G.A. Schmidt, 2009: Solar trends and global warming. J. Geophys. Res., doi:10.1029/2008JD011639.

    We use a suite of global climate model simulations for the 20th Century to assess the contribution of solar forcing to the past trends in the global mean temperature. In particular we examine how robust different published methodologies are at detecting and attributing solar-related climate change in the presence of intrinsic climate variability and multiple forcings. We demonstrate that naive application of linear analytical methods such as regression gives non-robust results. We also demonstrate that the methodologies used in Scafetta & West [2005, 2006a, b, 2007, 2008] are not robust to these same factors and that their error bars are significantly larger than reported. Our analysis shows that the most likely contribution from solar forcing a global warming is 7±1% for the 20th Century, and is negligible for the warming since 1980.

    This is astonishing. The GISS is now saying that the Sun has almost no effect on warming. What's next? The lungs have almost no effect on breathing? The air has almost no effect on flight? The ocean has almost no effect on fish?

    Someone cue the circus music. How many GISS scientists can fit into a Volkswagon?

    What is astonishing is that someone who has obvious intellectual capabilities can be so dishonest.

    You know full well what is being said is that the sun has been steady enough that there has been little contribution to the increase on it's part.

    The fact that you approach it by denigrating the efforts of the scientists, and useing false humor, simply shows the intellectual poverty of your viewpoint.

    true, but we've gotten used to your inability to distinguish reality from wishful thinking. it's kind of cute, imo.

    warmest regards and a very merry christmas to you and yours.

    There is a lot wrong with that paper according to Scafetta (one of the authors of several papers this one claims to refute).
    Nicola Scafetta, Physics Department, Duke University

    Merry Christmas si modo.

    PLEASE shorten this post, and give the LINK, as per copyright rules of this board.

    Question:

    WHAT brought us out of the ''snowball earth''? What made the glaciers melt?





    Hint:

    NOT the sun's rays/heat....

    :lol::lol:

    merry Christmas Del!

    CO2 caused the melt....from natural events....massive earthquakes and volcanoes releasing the gas....

    Without the CO2, we...the Earth, was destined to stay frozen.

    We need to give THANKS and praise, to CO2!!!

    2 points....

    CO2 is released naturally, not just from manmade uses.

    CO2 can cause the warming of the earth enough to melt the glaciers of an entirely frozen earth, so it CAN be the scientific culpret of global warming today.

    AS TO whether this is all from man made causes or a mixture of natural and man made causes, is up for debate and scientific scrutiny....I would NOT rule out one theory or the other....

    the document is way too long...can you give your synopsis of why you say i am wrong? is it the volcano/ earthquake part? IT CERTAINLY is NOT the carbon released in to the atmosphere that began our warming.....?
