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?

For the Classroom Wall: Polar Bears are Doing OK

Polar bears are good for catching the attention of the young who are told the poor bears are all but dead in the water from the melting ice.  

Children are urged variously to do such things as: 

Help save them. Screw up your own life.  Turn your back on generations of hard-won effort and industrial progress.  Feel bad about just about everything,  Just look at what's happening to the polar bears. Turn off lights.  Hassle your parents.  Be afraid of global warming.  Blame humanity for it.

Example here: http://www.thedailybeast.com/newsweek/2007/04/15/will-polar-bears-be-ok.html
'Sean Hussey and his twin sister, Erin, are only 9 years old, but they already know all about global warming. And they're worried, very worried. Teachers at their Hillsborough, Calif., school have shown them pictures of melting glaciers. Sean fears that polar bears will be left homeless. "I like polar bears a lot," he explains. Erin is also concerned about what she calls "the animal side" of climate change. "There are lots of animals that shouldn't die," she says. "The humans are the ones who are causing it." '

Meanwhile, the polar bears are doing OK.

What does that tell you about the scamsters of climate, class?  Pretty shoddy? Yup - that's about right.

For a sensible view, one based on reality and not the wishful fantasising of malevolent zealots, here are some observations by Matt Ridley.  Extract:

'In other words, the claim that polar bear populations are declining at all, let alone due to climate change, is a manufactured myth, designed for media consumption and with very little basis in fact. That it works all too well is demonstrated by an episode in 2011 involving Sir David Attenborough. In a television series the brilliant television presenter, unwisely diverging from neutral natural history, had asserted that the polar bear is already in trouble. When challenged by Lord Lawson that ‘the polar bear population has not been falling, but rising’, Sir David responded. He was quoted by The Daily Telegraph as saying ‘Most [polar bear populations] are in decline and just one is increasing – for a number of factors – one being they have stopped hunting…Lord Lawson is denying what the whole scientific community is accepting and working at and it is extraordinary thing for him to do’.
Much as I admire and like both men, I have to say that the evidence suggests that Lord Lawson’s account is closer to the truth. The International Union for the Conservation of Nature estimated in 1966 that there were 10,000 polar bears in the world; in 2006, the same source estimated that the population had risen to 20,000-25,000 bears. Had Sir David examined the text on the PBSG’s website he would have found that all but one of the eight sub-population declines he cited were in fact based on ‘beliefs’ or future projections. As demonstrated by another recent mistake in another television series, this time an exaggerated claim for temperature change in Africa, Sir David is not being well served by his BBC researchers these days.
Zac Unger documents in his recent book Never Look a Polar Bear in the Eye, how polar bear ‘decline’ is now a large and lucrative industry and in places like Churchill, Manitoba, organisations like Polar Bears International cynically use the imagined plight of the bears to raise money, and push propaganda at young people about changing their lifestyles and those of their parents.'

His writing was inspired by a study made by a polar bear expert Susan Crockford.  It is available for download here at the Global Warming Policy Foundation site.

Her study is entitled '10 Good Reasons Not To Worry About Polar Bears'

That would make a good title for a display on the classroom wall would it not?  The children would be pleased.  Why not help put their troubled minds at rest?

Note added later on 17 March:  The Heartland Institute in the States has produced an advertising-hoarding that could provide ideas for a wall display although it is perhaps too political for the classroom itself::
