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?

Misleading temperature graph (guess in which direction) used by UK Exam Board

'Britain’s largest exam board has been accused of “brainwashing” pupils by forcing them to use an inaccurate temperature graph that exaggerates the scale of global warming.'

 An article published in The Telegraph today asserts that the Assessments and Qualifications Alliance (AQA), the UK largest exam board is guilty of the following:

Ice core temperature reconstructions ignored.
Medieval Warm Period downplayed.
Current world average temperature exaggerated.
Most recent Ice Age ignored.
Children's extbook from 1990 used a source of temperature chart

Extract from article in the Daily Telegraph (UK) today:

'Kato Harris, head of Geography at South Hampstead High School in north London, has written to the exam board to highlight the errors.
He said: "It is demoralising and frustrating when we are trying to be accurate, rigorous teachers, imparting to our pupils the latest scientific knowledge, only for the exam board apparently to show ignorance of scientific developments in the last 15 years."
The graph published in the exam paper was titled ‘Timeline of the mean world temperatures over the last million years’, even though no such record exists.
Pupils were asked to mark with an X the “recent rapid rise in global temperatures”, as well as the coldest period.
AQA said the graph was simply meant to show “generalised trends” in global temperature and claimed that it displayed a "similar" pattern to the ice core reconstruction.
But Dr Benny Peiser, director of the Global Warming Policy Foundation and a social anthropologist at Liverpool John Moores University, said the graph contained “shocking inaccuracies”.
“I have no idea where they have got their data from, but it’s completely wrong. The graph exaggerates the case of global warming and it shows scientific illiteracy.
“I think this is highly misleading and the fact that it was included in an exam papers just shows how suspicious we should be with a lot of the information presented to students.
“There is a lot of pressure on schools and exam boards from government to educate our children in this way, but if we want to have a well educated population children need to know how science works, and they shouldn’t be brainwashed with misleading information.”'
