What does the science say in regards to the effect of elevated CO2 on major food sources across the globe?
It is well known that airborne CO2 acts as a vegetation fertilizer, which fortunately for the world, has produced a vast 'greening' of nature. Some 70% of greening is attributed to increased CO2 fertilization say the NASA researchers.
In regards to agriculture crops, a new study has again determined that increased CO2 will produce greater yields.
This peer-reviewed study focused of rice and maize.
"Rice is the most consumed staple crop in the world and maize is close behind in rank as the third most important cereal crop. Their annual yields are consumed by billions of persons worldwide.....Pingale et al. report that elevated CO2 positively influenced the growth and productivity of both crops. Plant growth and yield parameters such as leaf area, stem dry weight, panicle dry weight, cob dry weight and grain number per cob were all significantly increased under elevated CO2. And the end result of these several enhancements was a CO2-induced increase in both rice and maize grain yield."
The included column chart from the study depicts the yield increases for both crops.
