I would hope we have better climate prediction technology and methodologies than those 70s scientists who thought we were in a global cooling phase.
Think: supercomputers, satellites, GIS, etc. Our scientific tools have come a long way since 1977. On 2/7/07, John Robbins <[EMAIL PROTECTED]> wrote:

Its been 2 years so far. One thing to note with any fluorescent bulb is that every time you turn it on you shorten the bulbs life. IE, if you never turned off the bulbs you might get 5 years of use, but if it was in a bathroom where it was turned on for 10 minutes for 6 times a day you might get 2 years. This might explain why I haven't had but one or two burn out... I always forget to turn lights off (why I got CF in the first place) so my lights don't get cycled as much as a very power conscious person with incandescents would cycle theirs. If for nothing else, they are perfect for shop lights.... I had a bad experience with a $40 fluorescent hand held light (lowes carries it..), so went with the good old bulb on a cord light. I went through like 3 incandescent bulbs in one day from bumping into things and the light burning out. Put a CF in there and it takes TONS more abuse. I have broken two or three though (they don't like to be dropped 2-3 feet). > Plus don't they contain mercury? What do you do with them when they > burn out. > The ones I bought two years ago do. The one I bought last week doesn't... don't know if this is a brand thing or a industry wide change.
