Rising temperatures and increasing carbon dioxide are leading to multiple benefits and perhaps the most important of those is increasing crop production.
The first of the reports warned that future production of vegetables and legumes would decrease by more than 30 percent with an expected rise of 4 deg C… The primary reason for the prediction of famine is a sharp decrease in water availability, even though recent reports indicate that previously arid portions of the Earth are experiencing a significant net increase in soil moisture due to a combination of increasing precipitation and CO2 fertilization — both effects of our changing climate.
Buried in the report is an admission that contradicts the hysteria engendered by the headlines. According to the authors, a 250-ppm increase in CO2, without the exaggerated temperature increase, would boost crop production by an average of 22 percent. That’s correct, more food as a result of increasing CO2.
The second report projects decreases in corn (maize) production due to increasing heat waves. This increase in extreme heat was based on the same exaggerated 4 deg C increase in temperature as the first study.
According to the USDA, corn is the largest component of the global grain trade, and the United States is the world’s largest producer. Corn is thus one of the country’s most important agricultural products, processed as sweet corn, cornmeal, tortillas and, thankfully, bourbon. It also is the primary feedstock to fatten cattle, chickens and hogs.
Fortunately, despite a continuing rise in temperatures, the world and America have set new corn records on an annual basis. The world’s remarkable ability to increase food production year after year is attributable to mechanization, agricultural innovation, CO2 fertilization and warmer weather. World grain production figures show that crop and food production has steadily increased, with only positive effects from our changing climate.
Historically, crop growth has ballooned in times of high temperatures and declined drastically during cold periods. Over the last 4,000 years we find that previous periods of much warmer temperatures coincided with increasing food and prosperity leading to the rise of great civilizations that were relatively rich and well fed. Prosperous periods were interrupted by times of great despair as the Earth plunged into global cooling. With names like the Greek Dark Ages, the Dark Ages and the Little Ice Age, intervening cool periods featured crop failure, famine and mass depopulation.
Corn production in the U.S. presents a conundrum for environmental activists. On the one hand, they engage in fearmongering with predictions of famine based on questionable climate models. On the other hand, as enemies of fossil fuels, the activists promote ethanol production to replace our oil-based transportation fuels. Every acre of corn diverted to ethanol production is an acre that is no longer feeding the world’s hungry. In 2008, Herr Jean Ziegler, the United Nations’ Rapporteur for the Right to Food, claimed that “to divert land from food production to biofuels is a crime against humanity.”
