In science there are things such as “group thinking”. The issue of global warming being a prime example. Global warming got totally blown out of proportion partly because of the politics behind the peer review process. In this case “correlation does not mean causation” has become an excuse to not look at the data. Tusenfern’s ridiculous example has been used before. The comparable in the global warming issue is if there is a hurricane, flood, hot year, iceberg caving off the answer is the same “ITS GLOBAL WARMING! QED”.
