Bee-dubya-ell,

BillD,


A 15% change in one year on a variable that I have been told takes 30 years to be affected by man-made changes seems like something more than "slightly". We are seeing the results of actions 30 years ago-- 1975 or so. When did we stop the use of CFCs?

Present satellite data does not tell us the future duration of the ozone hole.


Les in Chorlton,

"Isn't ozone depleation caused by organic fluoro and chloro compounds from fridges and freezers? "

Never let it be said that facts should interfere with a point of argument...
