Ridiculous claim: In the next twenty years, trace amounts of CO2 will cut China/India wheat yields in half?

The document, published June 28, reveals disturbing scenarios. According to researchers in the next 20 years wheat and rice yields in China and India will drop by 50% because of more frequent droughts, while the food demand of the population will increase by 20%.

The document can be found here:

It is not a peer reviewed paper, but is a report by a private research group in India. The study was funded by the MacArthur Foundation.

In reading the Executive Summary I notice that they say "will" instead of "may" or "is likely to." They do not give probabilities. Maybe the full report does. They do discuss both non-AGW causes as well as AGW causes.

The report may not be the best science, but it should not be written off either.
