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.

Climate Criers are liars. Need more reports of plant and animal life, and human needs and habitat too that benefits with climate change and/or sees no impacts. Fight the climate change hoax on a two front war: 1)Fight the theory and 2) expose the lies that the planet is doomed
North American farmers have had a very difficult 2019. Late spring planting in mud and an early start to winter got the headlines, but the real ongoing headache is surplus production. Despite the weather (or climate) , we’re cranking out too much of a good thing. Rising atmospheric CO2 may contribute to this, but the real ‘culprit’ is competition. Farmers are competitive, they use all the tools available to them to increase production, then suffer the vagaries of supply and demand.
The United Nations and their ilk encourage Third World peasants to plant crops in Saharan regions for propaganda photo ops. If they starve, it’s because of incompetence and corruption.
Climate alarmists say that there is only one planet earth. That isn’t true. There is the real planet, and the fictitious one made up of lies to promote the agendas riding on the climate change movement. In the real world food production is increasing, in the fictitious world it will fall. In the real world hurricanes and other disastrous weather events are occurring as they always have, in the fictitious world they have increased substantially. In the real world the Maldives Islands have their surface area expanding. In the fictitious world they are sinking. The climate change dogma is so out of touch with reality that the only place the alarmists can live is in their fake world.
Thank you David for that statement. Well written
It’s not hard to understand the new paradigm in climate science that is based on correct physics and supported by solid evidence in experiments, studies and data for Earth and planets throughout the Solar System.
