evidence: - The Newsweek story, which did warn of a "cooling world," has been criticized and largely debunked — by its own author. Cruz’s claim that "advocates of global cooling suddenly shifted to global warming" ignores the fact that there was no scientific consensus in the 1970s about global cooling. [...] Cruz, March 24: I read this morning a Newsweek article from the 1970s talking about global cooling. And it said the science is clear, it is overwhelming, we are in a major cooling period and it’s going to cause enormous problems worldwide. … Now, the data proved to be not backing up that theory. So then all the advocates of global cooling suddenly shifted to global warming. [...] Bulletin of the AMS, September 2008: An enduring popular myth suggests that in the 1970s the climate science community was predicting "global cooling" and an "imminent" ice age, an observation frequently used by those who would undermine what climate scientists say today about the prospect of global warming. A review of the literature suggests that, on the contrary, greenhouse warming even then dominated scientists’ thinking as being one of the most important forces shaping Earth’s climate on human time scales.
