@TedNordhaus asserts that “a federal climate effort [must] take agriculture seriously…, including [GM] crops.” This positive take on GMOs as a US climate solution rests on assumptions that are not well supported by the science THREAD #ClimateAction #ClimateCrisis #GMO #scicomm
Nordhaus argues that GMOs boost yields, reducing land conversion to agriculture + therefore reducing GG emissions. The problem is that there is no scientific consensus on GM crops boosting yields, nor is the science clear that yield increases lead to land not being used for ag 1/
If a GM yield effect does exist, it is difficult to establish the difference it makes from on-going yield trends. Research by @Jack_Heinemann shows that cereal yield increases in Europe + US were the same despite the absence of GM crops in Europe 2/ tandfonline.com/doi/full/10.10…
