Something that really strikes me about the GM/Climate change parallel is the directionality of the science and action. Climate change is occurring because of actions that are *already* happening/ have happened. The science of climate change has sought to quantify these actions (CO2 emissions), model & predict their effects. Then you have a decision about what to do with that information. GM seems to be the other way around: a technology developed but little deployed because people object to it in principle. We don't *have* the scientific evidence to be able to say what effect it will or won't have because the work is destroyed before it's done. Climate change is all evidence and no action. GM is all action and no evidence.
