Is your statement suggesting that we have enough knowledge to control the earth's temprature by manipulating CO2 levels?
CO2 is about .0375 percent of our atmosphere. If every human started walking to work and never drove again and we stopped using transportation fuels all together according to this chart we would reduce CO2 by about 20%. If CO2 dropped in the same ratio the percentage of CO2 in the atmosphere would be .03% or 300 ppm. This is still at the highest pre-industrial range for CO2. If we took such a step you think we can predict what the impact will be? I don't. In the past few weeks I have not found a source for any scientific study stating we can make such a pridiction with any certainty. However, there are some who suggest other factors may be contributing to the higher tempratures. I think we should make informed decisions about energy uses that are causing CO2 levels to increase.
