Dr. David Burton is a Soil Scientist and Professor in the Department of Plant, Food, and Environmental Sciences in the Faculty of Agriculture, Dalhousie University, Canada: One of the most pernicious examples of disinformation promoted by the Climate Industry is the claim that manmade climate change from CO2 emissions threatens agriculture and “food security.” That’s the exact opposite of the truth. CO2 is “plant fertilizer,” and hundreds of agricultural studies have shown that higher CO2 levels are dramatically beneficial for agriculture, to levels far above what we can ever hope for outdoors. Most plants grow best with daytime atmospheric CO2 of at least about 1500 ppmv.
