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?

More Materials on Climate for the Conscientious Teacher

The Australian Carbon Sense Coalition has published a presentation by H. Leighton Steward which could serve as useful illustrated compendium of arguments against alarm about CO2 in the air.  It is 90 pages, mostly graphical, in a pdf.  Hat-tip: Tom Nelson.

Here is a montage I made of a few of the graphics (each one occupies a page to itself in the original):

I have spotted a few typos so far (I rather crudely corrected one above - see red u for nitrous oxide!), some parts say 'modified' or 'adapted' from source materials,  and some of the information does not have sources given, so some checking would be in order before using it, but overall my impression is hugely favorable.  This looks like a very handy document to have around, and to make use of for projects and illustrations on the classroom wall.  A lot of interesting exercises might follow merely from sharing out a selection of pages and challenging your pupils to check them out to see what further support, or criticism, they can devise or discover from other sources.

The Carbon Coalition encourages widespread use of their materials e.g. from their 'About' page:
'Material on this site is protected by copyright. However we encourage people to copy, print, resend or make links to any article providing the source, including web address, is acknowledged. We would appreciate notification of use.'

They provide more downloadable pdfs here: http://carbon-sense.com/carbon-sense/
