There is little evidence that Joe Average knows or cares about the consequences of more CO2 in the air. Many of the consequenses predicted for decades in the future have arrived already. People don't want to talk about it. I notice after three weeks only Inky has bothered to voice an opinion. Could it be that only 500 people submitted all 8,000 ideas and there are now only 50 people who ever read or post here? Or, more likely, the subject is simply of little interest to Big Thinkers! :(
