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?

Calming the Climate Curriculum - rejoinders and 'Did you know?'s
CFACT has just published (hat-tip NoTricksZone) a set of brief counter-arguments to some of the kinds of remarks that can trip off the tongues of those still convinced by the case for alarm over CO2. Some examples:
'CO2 is a greenhouse gas and it has been rising steadily. How can you deny global warming?'
'Haven’t the past few years shown global warming to be worse than we thought?'
'How can you ignore thousands of scientists who say manmade global warming is a serious threat?'
'97% of scientists say manmade climate change is real. How can you go against them?'
'Don’t graphs show that current temperatures are the highest in 1,000 years?'
There are 8 pages in a pdf file of these questions and answers here: http://www.cfact.org/pdf/Climate-Change-Q&A-Truth-File-2012.pdf
When the exams are over, or if the mark schemes are tolerant of dissent, or if the pupils are otherwise not to be judged on their conformance to climate cult dogma, then this document could provide material for many displays for the classroom wall. These could be used to encourage fact-checking and further investigations by pupils into these or any other remarks or assertions they may have encountered from those who want to scare them, and the rest of us, into thinking and doing what they want us to.
A promising initiative is also underway led by Anthony Watts at WUWT. He has invited suggestions for 'Did you know X' tidbits that he could use in a forthcming presentations, as he explains:
'The concept is simple and revolves around the question “Did you know?” and climate science.
Here’s how it works.
Every one of us has some little tidbit of information they learned about climate science that isn’t being told by the MSM and doesn’t fit the narrative. I’m looking for a series of “Did you know?” tidbits to use in an upcoming presentation. For example:
Did you know?
The infrared response of Carbon Dioxide in Earth’s atmosphere is curved (logarithmic) rather than straight (linear) as is often portrayed in science stories?'
Several hundred suggestions have been made in the comments, and not all of them of course are sensible or plausible. But presumably in due course, Watts will winnow the wheat from the chaff and may produce something of interest for use in the classroom.
Supplement added shortly after posting
A Cambridgeshire councillor has attracted a great deal of very informed support for his sceptical position on CO2 alarmism. One commenter provided him with a very interesting list of quotes, comments, and apercus from scientists who share that view. The details are on Nick Clarke's blog here: http://nickclarkeconservative.wordpress.com/2012/10/22/climate-some-comments-from-scientists/

These also look like a very rich resource for classroom use.
