I think it's pretty arrogant of us as a human race to think that WE can stop the earth's natural climate cycle.  When we came out of the last ice age, do you think all the ice melted because the dinosaurs were driving Hummers and using incandescent light bulbs??  The earth goes through NATURAL climate cycles.  It is up to US to adapt to IT - not make IT adapt to US!

I'm all for being more efficient.  That's one of the driving factors for innovation and invention and it's what has made us as humans so great.  If compact florescent bulbs are more efficient than other light bulbs and they save money, then the free market will drive their adoption.  But it's not up to governments to force this option by banning other forms of lighting...  

Rather than focusing our efforts on stopping climate change, we should be more concerned with adapting our lifestyles to the changing climate.  After all, we didn't go extinct after the "global cooling" scare in the 70's...  If Florida is going to be under water in 50 years because some ice off of a few glaciers melted, then start buying land further inland now while it's cheap.  In 50 years it will be ocean front again!  :)
