Paul's note: Congratulations, Canada, on ratifying Kyoto! Take a break to
celebrate. Then, write, phone or email your MP to thank/chastise him/her
(depending on how s/he voted). As Steven Harper says, the fight is only
beginning. Positive reinforcement is important. Plus, we still have to
implement this thing ...

Actually Ms. Crockatt is partially correct.  The ozone hole is indeed  much smaller this year than  in 2000 and 2001 and has split into two and this due to global warming.
The following is a précis of the NASA report

NASA states that the Southern Hemisphere's stratosphere was unusually disturbed this year  because of warmer than normal temperatures around the edge of the polar vortex
that forms annually in the stratosphere over Antarctica.
The main ozone depletion region, from 11 to 22 km. above the Earth, has large ozone losses, similar to the last few years. At more than 24 km. above the Earth, surface
measurements show higher than normal ozone concentrations and higher temperatures.
 The combination of these layers indicate total ozone levels in a column of atmosphere will be higher than observed during the last few years . However, some layers may
still show complete ozone destruction by early October, when ozone depletion is greatest.
The last time the ozone hole was this small was in 1988, and that was also due to warm atmospheric temperatures. Conditions change from year to year. There is no clear
trend.
 While chlorine and bromine chemicals cause the ozone hole, low temperature is also a key factor. The lower the temperature the greater the ozone destruction. This
counterintuitive result  stems from the fact that cold conditions lead to the formation of thin clouds. Chemical reactions on surface the cloud particles help chlorine and
bromine gases to rapidly destroy ozone. No clouds, no reaction, no hole.
The process is well understood, and has absolutely no bearing on the  Kyoto Protocol. We are talking about stratospheric not atmospheric temperatures.

The anti Kyoto arguments of the Petroleum Lobby have a similar structure to those of the anti  Evolutionists and most are as equally valid. The Ozone argument is a good
example.
