Why is there so much preoccupation with atmospheric CO2 concentrations and reducing anthropogenic CO2 emissions when it is well documented in the peer-reviewed scientific literature that the CO2 contribution to the overall greenhouse effect is so weak that it can be easily supplanted by small changes in clouds and water vapor, or natural climate-changing constituents?

Something for the classroom wall: Central England not part of the G in CAGW?
What is so special about central England that it should escape the man-made 'global' warming we have been told is so worrisome that we must do all we can to destroy industrial civilisation, including deliberate efforts to scare children into becoming 'little climate activists'? The projected catastrophe seems to be passing England by - that part of the sceptred isle can be seen to be enjoying a modest, and pleasant warming excursion of a kind it has seen many times before. At least until the recent summers ill-suited for barbeques despite the fervent hopes of Met Office modellers, and recent winters well-suited for cross-country skiing.
Nothing seems extraordinary in this temperature series, one which shows a modest trend and a lot of irregular variation about it. The rising CO2 emissions look quite irrelevant. There is clearly no basis here for alarm. We need the services of computer specialists willing to speak as oracles of doom in order to provide enough substance for political activists to spin an entire body - the IPCC, numerous governments, and a great many in the mass media, into severe agitation. Sadly, a great many teachers have been caught up in the swirl, and of course sadder still, a great many children have been told their societies, and of course the polar bears, are all but doomed. Unless they obey, and get their parents to obey, and get their societies to obey, the diktats of those political activists.
Hat-tip for drawing attention to the graphic: Tony Brown.
His WUWT article today on climate (esp temperature) history is well worth reading in its own right. He concludes:
'The globe appears to have been gently warming for 400 years- with numerous reversals and cold periods interspersed with warm ones. Within this overall trend can be discerned regions running counter cyclical to the warming trend, as was observed in the article ‘In search of cooling trends’.
We estimated around one third of all stations to be cooling, a figure now endorsed by the Berkeley study. The assertion regarding lack of climate variability cited at the top of this article by two of the most prestigious climate organizations cannot be supported-there were periods around as warm as today as well as very cold periods, demonstrating great variability, no doubt there were also areas running counter cyclical to the prevailing trend, as can be seen today.'
