Writing in his World Climate Report, editor Patrick J. Michaels took Karl to task for reporting only half the story.

Citing studies from the Goddard Institute for Space Studies, the Geophysical Fluid Dynamics Laboratory, and the United Kingdom Meteorological Office, Balling says that the combined effects of climate change and higher concentrations of atmospheric carbon-dioxide could boost soybean yields in Iowa 20 to 30 percent.

Along a similar vein, Balling cites a 1996 study by Y. Xue and J. Shukla (Journal of Climate, Vol. 9, 3260-3275): "[T]hey showed that increasing plant growth in the drylands could promote local precipitation, further acting to cool the surface and near-surface conditions."
