re: That's the website I usually go to for that info.
I agree. I had the same argument when the CFC issue came up with the ozone hole over the Antarctic. I knew that there was no way the scientists could truly tell you what the trend was over centuries, that the data was all extremely new.
Now I'm not saying that it still isn't a good idea to take precautions just in case the assumptions of trends are absolutely correct but in all cases the actions should always have additional benefits along with the defensive ones.
