Needing More Food, but Biting the Hand that Feeds Us

As evidence for this latter contention, the Center for the Study of Carbon Dioxide and Global Change provides a listing of the experimental findings of a vast collection of scientific papers that support this point of view of the subject in their Plant Growth Database. There, it can be seen that enriching the air with CO2 almost always leads to significant increases in the photosynthetic rates and biomass production of all of the world's major food crops. And as for the highly-unlikely increase in global temperature that the world's climate alarmists predict to result from projected increases in the air's CO2 content, there are also many studies that reveal the positive consequences of warming for agriculture in Earth's cooler high-latitude regions, such as the recent study of Meng et al. (2014) dealing with maize production in the northern reaches of China. And there is also the significant body of work that reveals that as the atmosphere's CO2 concentration rises, the various temperatures at which different plants photosynthesize most proficiently rise right along with it (see for example,The Spector of Species Extinction: Will Global Warming Decimate Earth's Biosphere?.
All things considered, therefore - including the many journal reviews on this website that recount the many failures of the most sophisticated climate models yet developed to replicate real-world past climatic histories in almost all parts of the planet (see Climate Models and their Limitations in the Topical Archive) - perhaps one of the more prudent actions to take to assure the production of sufficient food to feed our descendants (as well as many of us) a mere three and a half decades from now would be to stop trying to reduce anthropogenic CO2 emissions.
