The sad thing is you, like many others, believe we can control global climate change when there is no solid evidence to suggest reduced CO2 emissions will make a difference in any climate change patterns. Read any journal from people in the "biz". You will read words like "we think", "its possible", "maybe", "we are not sure", etc. These are not words to rest expensive global policies on. Not to mention, has anyone done a study on negative effects of reducing CO2 emissions. There is simply to much hand waving happening in the science. I do not claim to have answers, but I do claim that no one else does either. Until the science matures beyond voodoo grade predictions, I'll continue to use my air conditioner.
