“One of the panel’s most striking new conclusions is that rising temperatures are already depressing crop yields, including those of corn and wheat. In the coming decades, farmers may not be able to grow enough food to meet the demands of the world’s growing population, it warns.”

…is in this LA Times story by b about the latest IPCC report which has so much gloom and doom in it, one of the lead authors, Dr. Richard Tol, asked his name to be taken off of it for that very reason.

Problem is, the agricultural data doesn’t match the LATimes/IPCC claim, see for yourself:

Source: USDA data at http://apps.fas.usda.gov/psdonline/ plotted by Dr. Roy Spencer.

Not only is the LATimes/IPCC claim about agriculture false for the world, but also the USA:

Source: USDA Data here compiled by Dr. Mark J. Perry at the Carpe Diem blog.

In fact, U.S. Corn Yields Have Increased Six Times Since the 1930s and Are Estimated to Double By 2030 according to Perry.

Note that temperatures in the US Corn belt aren’t rising, but models are, and as we know, the IPCC prefers model output over reality.

Why is it that checking such simple facts are left to bloggers and independent thinkers like Roy Spencer, instead of “professional” journalists like ?

Maybe he’s just too lazy to check facts like this? Or, is it belief mixed with incompetence?
