Climate Doomsters Moan As Global Crop Yields Soar

Written by James Taylor

There they go again. A new paper relying on modeling rather than real-world observations, claims global warming is creating a food production crisis.

The media are breathlessly promoting the doom-and-gloom paper, even as global food production reaches yet another new record.

Climate alarmists have published a new paper in the obscure journal Science Advances, claiming all modeled scenarios of global temperature increase will result in falling food production by the end of the century.

According to the authors, immediate and substantial action to reduce global greenhouse gas emissions could keep the decline in production to 5 percent. With less action taken, the alarmists claim food production will decline 25 percent.

Computer models, however, are only as accurate as their programmed underlying assumptions.

Computer models that are programmed to assume more atmospheric carbon dioxide (which horticulturists pump into greenhouses to enhance plant growth), warmer temperatures, fewer frost events and longer growing seasons, are bad for agriculture.

This will, of course, predict that all warming scenarios will cause crop production to fall. Fortunately, we can test such assumptions against real word crop production as global temperatures have warmed.

According to the United Nations Food and Agriculture Organization (FAO), global crop production is experiencing long-term, mid-term, and short-term improvement. New records are being set virtually every year.

FAO data shows global crop production – as shown in the FAO chart below – increased 10 percent in just the past 10 years as our planet modestly warms.

Moreover, FAO data show global food production has increased 25 percent since the year 2000.

The news is even better regarding yields per hectare or acre. Yields per acre are consistently increasing in nearly all nations, with less land required to grow a greater amount of food.

In the United States, for example, yields per acre have increased 25 percent during just the past decade.

So even under a worst-case scenario, global warming would have the impact of – gasp! – keeping global crop production steady at where they were just a few years ago.

However, even that appears unlikely to happen, as all real-world evidence shows crop production continues to climb and set new records every year with ongoing warming and each incremental rise in atmospheric carbon dioxide.

    Well well, the truth being the exact opposite of what the alarmists tell us, whoda thought it.

    There is a direct, linear relationship between photosynthesis and atmospheric CO2 concentrations between 300 PPM and 1600 PPM. The 40 foot tall ferns of the Jurassic period were the result of higher levels of CO2. Plants produce sugars, starches, cellulose and OXYGEN.

    Information provided is from bureaucratic organizations never get out into the hectares where the significant crop losses are covered up to avoid the panic of food shortages that are coming. This because the Grand Solar Minimum and its erratic weather patterns of the current Solar Cycle. 19MM acres in the US have been under water and significant damage due to late plantings and early frost. Early snowfalls have compromised any salvageable remainder. Spring plantings are unlikely.
