This is not what the "study" found. It found that 97 percent of papers published agreed with the hypothesis of Global Warming. This high percentage was accomplished by the warmists having control of the journals, and not allowing alternate hypotheses to be presented. (See the Climategate e-mails)
In related but unreported news, it has now been 2778 days since the last major (Category 3 or greater) hurricane has made landfall in the United States. This shatters the old record for calmness of 2231 days, set 19 Oct 1906. This record calm period is, of course, caused by Global Warming, as would any increase in hurricane activity.
Worse then that. They only read abstracts to determine if the paper was pro, neutral or anti AGW. Some of the actual authors of the studies they reviewed are stating their paper was miss classified by the team. So not only are the AGW acolytes idiots, they are also criminals.
