I take it you were not even alive in the 1960's and 1970's, but that's okay as you can google it and find plenty of media articles on the subject. The particular portion of science I am referring to is the lack thereof in the entire GM agenda as none of it is peer reviewed nor capable of being proven due to lack of evidence. The Earth works in different ways at different times; Ways we only started discovery of when official record keeping began in 1914. Sure, tree rings, ice packs and geological layers give us some insight into the past, but it is far from "proven" by any means and no "climate model" to date can even predict the weather for TOMORROW, let alone the past or future.
You are on /., I urge you to look at this from an unbiased and logical perspective: We don't have all the answers, so why assume someone does when no evidence can prove it?
