There is solid evidence that points to the possibility of a mini ice age. The sun's most recent cycle of sunspot activity is less than the previous 11 year cycle. This is given as the actual cause of lower recorded global temperatures. The globe had been working its way out of the previous mini ice age which is given as ending in 1900. Given the last 11 year sun spot cycle was down; the current cycle is lower and the next forecasted to be even lower global temperatures are forecasted to continue to decline.
So what has, is or will be the consequences of government mandated reduced carbon dioxide coupled with lower temperatures? First less crop yields. Could it be the successes of twenty century farming was due in part to man's increased production of carbon dioxide? There is science that says that is true. Greenhouse farming pumps up to five times the normal amount of carbon dioxide into greenhouses to increase yield. Corn fields use carbon dioxide so fast that reduced levels can actually be measured in the center of large fields.
Now anyone that used statistics as part of their vocation recognized immediately the errors and defective models the global warming cult was using. Many quality control engineers required to certify the safety of products would have went to jail for using such flawed data. So government officials knew global warming data were a bunch of hocus pocus.
The question what civil, criminal, or moral penalties should Al Gore et al be subjected to?
