Butcherboy were the observed temperatures on your graph showing at most .2degree centigrade over 18 years derived from the urban heat sink affected Stevenson boxes or from Hansen`s doctored and adjusted GISS ones.Global warming despite rapidly increasing co2 is not rising to IPCC alarmist projections.Climate is multifactorial and it is dishonest to focus on one factor co2 which because it is easily measured can be polically presented as dirty carbon and therefore readily taxed .The whole scam is almost totally political!
