'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.'

Classroom Conundrums of Contradictory Climate Confusions: what are you going to tell them about the effects of climate change?
Steve Goddard has just published an updated list, thanks to a poster called Jimbo, of apparently contradictory conclusions. Also published by Pierre Gosselin. For example:
Amazon dry season greener
Amazon dry season browner
Avalanches may increase
Avalanches may decrease – wet snow more though
Bird migrations longer
Bird migrations shorter
Bird migrations out of fashion
Boreal forest fires may increase
Boreal forest fires may continue decreasing
Chinese locusts swarm when warmer
Chinese locusts swarm when cooler
Columbia spotted frogs decline
Columbia spotted frogs thrive in warming world
Coral island atolls to sink
Coral island atolls to rise
These, and the other links provided, are all to peer-reviewed literature ('but is it peer-reviewed?' was one of the spin options used by crisis-CO2 campaigners when challenged, but it is heard less often now that the IPCC has been exposed as relying very heavily on distinctly non-peer-reviewed literature).
It might be easier to tell your class that not only has climate science been degraded and poisoned by the IPCC activists, but much of the rest of the IPCC, the stuff on consequences, is in a bit of a mess too.
An earlier verion of the list was noted here in February: http://climatelessons.blogspot.com/2011_02_10_archive.html
