Kyle Swanson and Isaac Held make some odd comments in the Discovery News article (CCNet 3/3/09), which questions where global warming went.
Apparently, the 'radiative forcing' of CO2 will stay in an unknown hiding place for 30 years and then jump out on us! This sounds like an excuse for buying more time for the failing hypothesis which attempts to implicate CO2 as THE driver of climate. They also seem to claim that natural variability largely manifests itself as cooling rather than warming.
