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?

A sensible perspective on climate just published: an essay accessible to teachers of all subjects
Where might such a teacher go to formulate or deepen their own perspective on climate? Few would care to dive into the world of the complex computer programs at the heart of the alarmism. Few are in a position to dispute with those who assert a scientific consensus, or more specific appeals to authority. Yet they can all study expository, tutorial, and explanatory materials written by experts in relevant fields, and reflect on the credibility, consistency, coherence, verifiability and tone of them.
One such piece has been published today by the Global Warming Policy Foundation:
'The Truth About Greenhouse Gases'
by William Happer, the Cyrus Fogg Brackett Professor of Physics at Princeton University.
The essay begins with a quote from the Madness of Crowds:
“The object of the Author in the following pages has been to collect the most remarkable instances of those moral epidemics which have been excited, sometimes by one cause and sometimes by another, and to show how easily the masses have been led astray, and how imitative and gregarious men are, even in their infatuations and crimes,” wrote Charles Mackay in the preface to the first edition of his Extraordinary Popular Delusions and the Madness of Crowds. I want to discuss a contemporary moral epidemic: the notion that increasing atmospheric concentrations of greenhouse gases, notably carbon dioxide, will have disastrous consequences for mankind and for the planet. This contemporary “climate crusade” has much in common with the medieval crusades Mackay describes, with true believers, opportunists, cynics, money-hungry governments, manipulators of various types, and even children’s crusades.'

Note added 21 Sep 2011: Lubus Motl has fisked, and exposed as unimpressive, an attempt to discredit Happer's essay. Poor MacCracken - he may be a 'fat cat alarmist', but he is pretty thin when it comes to intellect and integrity.
