    Look, it's not my job to educate you about basic concepts you should have learnt at college. I don't know how old you are or your level of education but you ought to be embarrassed. So where is your fine feathered friend to demonstrate his woeful misunderstanding of both thermodynamics and physics?

    Apparently YOU don't understand that CO2 is heated by the Earth's surface, which COOLS the Earth's surface. Energy isn't free. You can't create energy out of nothing.

    The sun.
    That same car will LOSE all that energy again too, at night. It will be the same temperature as the outside air by morning.

    Nope. It's really as simple as he says it is. You are just trying to restate the same thing in a more complicated way. Your problem.

    A few days ago, an international research group from the USA, Canada and Switzerland led by Lorenzo Polvani of Columbia University (New York) published a sensational study in Nature climate change, which attributes a large part of the warming of the 20th century to CFCs (“Substantial twentieth-century Arctic warming caused by ozone-depleting substances“).

    CFCs don't deplete ozone. You can put CFCs in a tank full of ozone and no reaction occurs.
    No gas or vapor is a capable of warming the Earth. You can't create energy out of nothing.

    No, that would be YOU. It is YOU that ignores the 1st law of thermodynamics.

    I never asked you to educate me, and if I did, I'd be asking for my money back.

    It appears that he is now back from his hiatus.

    The woeful misunderstanding is yours, not his.

    Abstract

    The rapid warming of the Arctic, perhaps the most striking evidence of climate change, is believed to have arisen from increases in atmospheric concentrations of GHGs since the Industrial Revolution. While the dominant role of carbon dioxide is undisputed, another important set of anthropogenic GHGs was also being emitted over the second half of the twentieth century: ozone-depleting substances (ODS). These compounds, in addition to causing the ozone hole over Antarctica, have long been recognized as powerful GHGs. However, their contribution to Arctic warming has not been quantified. We do so here by analysing ensembles of climate model integrations specifically designed for this purpose, spanning the period 1955–2005 when atmospheric concentrations of ODS increased rapidly. We show that, when ODS are kept fixed, forced Arctic surface warming and forced sea-ice loss are only half as large as when ODS are allowed to increase. We also demonstrate that the large impact of ODS on the Arctic occurs primarily via direct radiative warming, not via ozone depletion. Our findings reveal a substantial contribution of ODS to recent Arctic warming, and highlight the importance of the Montreal Protocol as a major climate change-mitigation treaty.
