    Although this is new to Nature, it's not new to other journals. Here is one in Atmospheric Environment back in 2011.

    Oh no, it can only be CO2. No way a massive hole in the ozone layer can make a difference.

    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.

    Half of Late 20th-Century Arctic Warming Caused by Ozone-Depleting Substances – “It’s a Good-News Story”

    Ozone is continuously created by the action of UV-B sunlight on oxygen in the atmosphere.

    Science isn't a paper. It is a set of falsifiable theories. The 'hole' over Antarctica occurs during that pole's winter, when there is no sunlight. Another one forms in the Arctic pole during its winter for the same reason. You need sunlight to produce ozone.

    Can you tell me the institution where you studied thermodynamics and atmospheric chemistry, because they ought to be shutdown? I don't propose going through that load of bollocks yet again but suffice to say that CFCs do react with ozone (O3). The action of sunlight causes chlorine to be produced which then reacts with O3 to form chlorine monoxide (ClO) and oxygen (O2).

    Cl + O3 = ClO + O2

    Nope. Sunlight does not cause CFCs to be turned into chlorine. IF something does cause CFCs to disassociate (such as fire), chlorine is released, but it's so reactive it will react with something else long before it gets anywhere near the ozone layer. The ozone layer is continuously produced by the action of UV-B sunlight on oxygen. Ozone is also destroyed by UV-C sunlight near the top of the stratosphere. We can't destroy the ozone layer even if we wanted to.

    The sun.
    Yeh well there's more to it than that, don't attempt to deny it as it just makes you look ignorant.


    Why is the inside of a car hotter than the outdoor temperature on a sunny summer day?


    This phenomenon -whereby the inside of a car gets really very hot, much hotter than the outside -is known as the GREENHOUSE effect.

    This is what happens. Sun light travels from the sun in the visible part of the spectrum (i.e. we can see it!) and strikes the inside surface of the car. The sunlight is absorbed by the surface of the car (say the dashboard and the carpet) and since radiation is energy, the absorption of the visible radiation causes the surface that is struck to heat up. Now---- and this is the key part---- EVERY OBJECT emits energy at a wave length that is a function of the temperature of the object. Human beings around 100 deg F emit radiation in the INFRARED part of the spectrum. The human EYE cannot see this emitted radiation unless one uses special Goggles that enable this radiation to be converted to a range that the eye CAN see. In fact, this principle is the basis for NIGHT VISION goggles. Also SNAKES that catch rodents in the desert at night have such IR heat sensors!!!...

    At any rate, sunlight falls on the carpet of your car and then the carpet RE RADIATES that, the absorbed visible (short wave length) energy in the IR (long wave length) part of the spectrum. BUT water vapor and CO2 in the air in your car will ABSORB this re-radiated IR energy (the water and CO2 is transparent to the incoming visible radiation) and so the heat gets trapped in your car. This is because the incoming visible light gets absorbed and re-radiated at longer wave lengths and these long wave lengths are TRAPPED by the small amount of water vapor and CO2 present in the car.

    NEVER EVER leave a PET or a small child in such a situation... even if the temp outside is say 70 deg F which is not so hot, the interior of a car can easily exceed 100 deg F.
