'First, the non-climatic effects of carbon dioxide are dominant over the climatic effects and are overwhelmingly beneficial. Second, the climatic effects observed in the real world are much less damaging than the effects predicted by the climate models, and have also been frequently beneficial.'

The illustration above by Jo Nova. More at: http://joannenova.com.au/2011/03/shut-down-australia-and-save-0-01-degree/
The calculations, based on IPCC-style science, are provided by SPPI in a report which can be downloaded from here:
The report is very short, and the sums look easy enough. Why not get a class to do them for your country? Help the children see what all the fuss is about, and at the same time help yourself decide how much longer you can stomach pushing spirit-sapping mind-numbing propaganda from the WWF, the IPCC, etc, etc, etc
Notes added 8 March: (1) Here are some computation results for an EU scheme that would return an ostensible 0.002C impact for an expenditure of 2.9 trillion euros: http://notrickszone.com/2011/03/08/the-eus-serial-economy-killers-0-002%C2%B0c-for-e2-9-trillion/
(2) Here are results for many countries of the world, scroll down to find this table
Note 1 added 14 March: Jo Nova has new calculations of temperature rises:' ..The effect, according to the IPCC’s theory of man-made global warming' is not alarming: http://joannenova.com.au/2011/03/carbon-tax-australia-welcome-to-futility-island/ 100% reduction in Australian emissions from now to 2050 would reduce temps by 0.0154C using the IPCC approach, an approach which one can of course readily assume to be based more on PR-potential than good science.
Note 2 added 14 March. USA. Willis Eschenbach has been doing sums for a post on WUWT about the impact of EPA proposed CO2 reductions: 'Based on the reanalysis the results for projected atmospheric CO2 concentrations are estimated to be reduced by an average of 2.9 ppm (previously 3.0 ppm), global mean temperature is estimated to be reduced by 0.006 to 0.0015 °C by 2100.'
