David Lobell, a Standford University scientist, and his colleagues conducted a study gathering agricultural data (including temperature, rainfall, and crop production) from growing regions around the world between the years 1980-2008, and compared it to what the crop yield would have been had all the variables stayed consistent.
The results are as follows:
Corn production was lowered 5.5%
Wheat yields were lowered 3.8%
Wheat yields in Russia alone were lowered 15%
Some disagree with the results, however, claiming that we don’t know what the farm yields really would have been had the factors stayed the same, and the outcome could have been affected by any number of other things other than the temperature/environment.
The only crops that remained unaffected were soy beans and rice, which seem to thrive in higher temperatures.
What this does mean is that over the last few decades, the lowered production of crops due to global warming has caused the price of food to rise. So that explains it.
Take this information how you will and believe what you want — but I for one can’t ignore the fact that it seems to be getting a little warmer in here!
