Over the Antarctic, the Smallest Ozone Hole In a Decade

hypnosec writes "The ozone layer seems to be on a road to recovery over Antarctica; according to Europe's MetOp weather satellite, which is monitoring atmospheric ozone, the hole over the South Pole in 2012 was the smallest it's been in the last 10 years. The decrease in size of the hole is probably the result of reduction in the concentration of CFCs, especially since the mid-1990s, because of international agreements like the Montreal Protocol."

      Good job misrepresenting that. Here, let me post the abstract, literally the first thing you'd read:

      This Letter reports reliable satellite data in the period of 1980–2007 covering two full 11-yr cosmic ray (CR) cycles, clearly showing the correlation between CRs and ozone depletion, especially the polar ozone loss (hole) over Antarctica. The results provide strong evidence of the physical mechanism that the CR-driven electron-induced reaction of halogenated molecules plays the dominant role in causing the ozone hole. Moreover, this mechanism predicts one of the severest ozone losses in 2008–2009 and probably another large hole around 2019–2020, according to the 11-yr CR cycle.

      The paper does not say it's dependent on cosmic rays exclusively, instead it points out that cosmic ray activity seems to play a significant role in determining the activity of halogenated molecules destroying ozone. Guess which one of those parameters we've totally screwed around with from the 1970s onwards?

      *sigh*. If you're going to quote the scientific literature in support of your argument, you need to at least make some effort to understand it first.

      The paper says that cosmic rays strongly correlate with ozone depletion. The data point to cosmic-ray driven reactions of halogenated molecules as being the cause of the correlation. The *only* halogenated molecules present in the stratosphere in any significant concentration are CFCs. I'll repeat that: where the paper talks about "halogenated molecules", it's talking about CFCs, HCFCs and other man-made chemicals.

      Hence, this paper is presenting an alternative explanation to *why* CFCs damage the ozone layer. The prevailing hypothesis is that photolysis of CFCs (i.e. UV from the sun breaking them apart) is what kicks off the ozone-depleting catalytic cycle. This paper says "Nah, it's not photolysis, it's cosmic-ray-induced ionisation of the CFCs that sets the whole thing off".

      From the paper:

      In the CR-driven mechanism, the O3 -depleting reactions depend on halogen concentrations, CR intensity, and PSC ice (to hold the electrons) in the stratosphere [6,8]. From 1992 up to now, the Antarctic O3 loss has shown a clearest correlation with the CR intensity. This is because the total halogen amount of the stratosphere, particularly those of CFCs, is nearly constant in that period of time [30]; thus the regulating effect of CRs on O3 loss becomes manifest. In contrast, such a time correlation is hardly seen in the enlarging spring polar O3 loss during 1980s, since at that period of time, the halogen loading increased dramatically and thus ozone showed a drastic decreasing trend blurring the CR-O3 loss correlation. And in the pre-1980s, no significant halogen loading was found in the stratosphere, and thus no significant O3 loss was observed.

      Summarising that: since 1992, there's been loads of CFCs in the atmosphere, and hence the rate-limiting step in how much ozone gets broken down is how many cosmic rays there are. Before 1980, there were no CFCs in the stratosphere, and hence cosmic rays didn't destroy any ozone. Your bet is thus meaningless: this paper is part of the argument over *why* CFCs cause ozone depletion, not *whether*.

Anything beyond "anthropogenic gases are probably adding about 0.2% (1.6 W/m**2) to the Earth's heat budget at the surface" is extremely model dependent, and models are just not that good at predicting the detailed response of such a complex system.

      I am a computational physicist, and it is very clear after digging in to climate models a bit that climate models are not written by computational physicists, who typically have dealt with much simpler systems in much better controlled (and experimentally accessible) situations, which gives us a very healthy awareness of how inadequate our simulations are at capturing anything but the gross features of reality.

      If a computational model of a radiation detector comes within 10% of reality you're generally doing pretty well, and radiation detectors of various kinds are about as simple as you can get in terms of physics.

      So anyone who claims that climate models are adequate or even particularly useful as guides to policy response is likely not tightly coupled to reality. We don't really know what areas are likely to be affected by what kind of events. Even apparently simple things like an increase in hurricane force winds, or possibly an increase in the number of hurricanes, are hotly debated. No one, to the best of my knowledge, predicted ocean acidification as a likely outcome of increasing levels of atmospheric CO2, but this is likely going to be one of the more significant impacts. And so on.

      As such, it behooves us to pursue a number of policies that won't address any specific threat, but which will a) reduce human greenhouse gas emissions and b) increase our ability to respond the climate-driven humanitarian disasters. In the former category would be nuclear power development and other green power sources, and in the latter things like increased funds put aside for international relief via existing organizations.

      These positive actions have zero political support, however: people who are beating the drums regarding AGW policy are almost uniformly putting it in terms of controls and limits and restrictions on other people, which we know from far too much history never ends well, and certainly never solves the problem it was supposedly intended to address.

    This site is going way downhill with such idiots spewing political propaganda using techniques out of their party playbook instead of actually using their brains for something useful. If I wanted to read an anti-science site there's plenty of other places I can go so I'd rather not have such bullshit here.
    You've used the ozone issue as nothing but a trojan horse to push your own political agenda - that is an insult to the readers here that prefer to read something better than things excreted from the arse end of the batshit insane wing of US politics.
