Once again, the shrill calls for CO2 abatement to save us from starvation need closer examination…..Grain yields in most countries (other than Georgia) are climbing despite modest increases in global temperature. From a guest post on “Watts Up With That”.

Watts Up With That?

Guest Post by Willis Eschenbach

I keep reading these claims that we’re all going to starve because of global warming. People say it’s going to be the death of agriculture, that increasing temperatures will cause significant drops in crop yields. Here’s a typical bit of alarmism (emphasis mine):

A study by the International Food Policy Research Institute (IFPRI), indicates that climate change would hit developing countries the hardest, leading to massive decline in crop yields and production.

Whoa, a massive decline in crop yields due to increasing temperatures, sounds scary. So I thought I’d review the facts. Here is the global situation, showing the global yields of rice, corn, and wheat, along with the change in global temperature.

Now call me crazy, but what I see going on…
