   Kate should get on the phone to James.

   I wonder what they are gonna say in 2050 if the Ozone layer is the same as it is now?

     That they fix it. That their interdiction was directly responsible for saving the planet. Is what they’ll say, it is what they’ve said already.

       But appearantly right now it is getting worse again, So if it is no different by 2050 as they claim the Ozone will make a full recovery, than it is right now, then I guess the Montreal Protocol is junk science too!

       ME:
       Your guess would be correct!
       The Ozone layer responds to temperature and sunlight or lack of it and fluctuations are natural. There was no HOLE just a lessening of concentration! About now is when the concentration will start increasing so they had to proclaim disaster before the recovery. Now the event is on the books they can repeat the claim without updating the information until it starts to diminish again!

       LOL, sometimes I’m sooo right its scary. I was reading Anthony’s posting on this over at WUWT.

       “In the long term the ozone layer will recover thanks to extensive environmental policy measures enacted for its protection. This winter’s likely record-breaking ozone loss does not alter this expectation. “By virtue of the long-term effect of the Montreal Protocol, significant ozone destruction will no longer occur during the second half of this century,” explains Rex.

       Yep, we can all agree, we fixed it!!! Man’s triumph over …….. well…..something.

   That site omits a crucial factor – it’s referring to temperatures in the stratosphere (where the ozone is), not sea level temperatures in the lower troposphere. A better write-up is here: http://www.sciencedaily.com/releases/2011/03/110314100835.htm

   Cooling stratospheric temperatures is exactly what is predicted from greenhouse gas accumulation: it traps heat near the surface and warms the surface while cooling the higher layers of the atmosphere. Note that if the warming were due to solar factors, then both the troposphere *and* the stratosphere should be heating.

   It’s especially interesting that this year there have been cold stratospheric temperatures and high ozone loss despite a negative Arctic Oscillation. Normally a cold stratosphere is associated with a strong polar vortex and a positive AO. That also is consistent with the effects of climate change. This year, the negative AO was not due simply to weakening of the polar vortex, but also to the huge high pressure sitting over Greenland / Baffin / Canada, driven by heat released from the open water below. That heat was in turn due to the early melt and late re-freeze of these areas meaning they absorbed a lot more solar energy during summer.

     Based on the latest climatology Wild Ass Guesses. Thank you for sharing the Chicken Little Brigade’s latest regurgitated claims! Does it make you anxious to go back and consume more? You would probably get more respect if you used the favorite Vomitoriums like Surreal Climate or Airhead to upchuck your undigested fantasy!

   The Arctic ozone in March (the low point in the annual Arctic O3 cycle) correlates with the ENSO.
