    ScienceDaily (Dec. 7, 2009) — In the long term, the Earth's temperature may be 30-50% more sensitive to atmospheric carbon dioxide than has previously been estimated, reports a new study published in Nature Geoscience.

    This would agree with what we are currently seeing. The climate response, particularly in the Arctic and Antarctic has been much more than predicted.

    The results show that components of the Earth's climate system that vary over long timescales -- such as land-ice and vegetation -- have an important effect on this temperature sensitivity, but these factors are often neglected in current climate models.

    Dan Lunt, from the University of Bristol, and colleagues compared results from a global climate model to temperature reconstructions of the Earth's environment three million years ago when global temperatures and carbon dioxide concentrations were relatively high. The temperature reconstructions were derived using data from three million-year-old sediments on the ocean floor.

    Lunt said, "We found that, given the concentrations of carbon dioxide prevailing three million years ago, the model originally predicted a significantly smaller temperature increase than that indicated by the reconstructions. This led us to review what was missing from the model."

    :lol::lol::lol::lol::lol::lol::cuckoo::cuckoo: :lol::lol::lol:

    Is this science or a stand up routine?

    Modern CO2 is more Liberal and has delicate feelings

    Nature, Geoscience. A bit more credible than Watts or Limpbaugh.

    So, it should be a piece of cake to show us a temperature increase in a laboratory setting from a 140PPM increase in CO2, right?

    Maybe you can have the Earth atmosphere watch "The Crying Game" to put its sensitivities into hyperdrive?

    Classic! So, it must be genetically modified, hypersensitive CO2!

    None dare call it science!

    Come on, Old. Show us one lab experiment where adding 140PPM, not 400,000PPM of Hypersensitive CO2 makes the temperature increase!

    This CO2 is really twitchy and itching to make the temp rise!

    Oh, wait a second, did you think this was supposed to help your case? No! LOL
    You didn't, did you?

    Take it easy, Big Joe!...Some of these atmospheric gasses got sensitive feelings!

    Huh...

    Can anyone else smell the desperation flop sweat on these greenies? I sure can. So many posts so quickly after the IPCC abandons them.

    So...the models don't show what we want them to show. The obvious solution? Make up something!
