'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.'

Back to ACM on GCMs:
'Anyway, I'd like to introduce this little fella to you (see photo). After many minutes of painstaking research, Australian Climate Madness has decreed that all unusual or severe weather events of whatever nature, anywhere in the world, are solely the mischievous work of the Green Climate Monster (he gets bored easily). The GCM is responsible for the shrinking Arctic ice sheet, the growing Antarctic Ice sheet, advancing glaciers, retreating glaciers, heatwaves, cold spells, mountains of snow, absence of snow, droughts, floods, hurricanes, absence of hurricanes, very windy days, calm days, sunny days, cloudy days, foggy days, El Niño and his twin sister, the seasons, thunderstorms, absence of thunderstorms, excess rainfall, less rainfall, extinction of frogs, discovery of new frogs, fewer polar bears, more polar bears, everything else listed at the Warmlist, and plenty more besides.'
I could see this in a current affairs class - just keep a picture of the Monster on the wall, and stick press-cuttings all around it as the pupils bring them in every month on whatever weather, or other, event is being blamed on 'human-caused global warming', or 'climate change' as it seems to be known for short in the media. Class discussions could serve to identify the most ludicrous of each crop.
