A new Purdue University report and survey of on global warming finds that just 50 percent of scientists blame human causes, not the NASA-endorsed and widely distributed claim of 97 percent.

In a survey of nearly 7,000 in the agriculture field, found that most scientists agree that climate change is happening, but just 50.5 percent blame mankind.

“More than 90 percent of the scientists and climatologists surveyed said they believed climate change was occurring, with more than 50 percent attributing climate change primarily to human activities,” said the Purdue report published in the authoritative Bulletin of the American Meteorological Society and highlighted by MRC Business.

“Contrary to the repeated insistence of both climate alarmists and the media, scientists do not all agree on the standard climate alarmism talking points,” said MRC’s review of the scholarly report from one of the nation’s leading ag schools.

“More shocking was that just 53 percent of climatologists surveyed thought ‘climate change is occurring, and it is caused mostly by human activities.’ While that number of climatologists was small, the result is still significant,” added MRC.

Most of the farmers interviewed agreed that climate change is occurring, but just 8 percent blamed humans.

The media has often hyped the 97 percent figure and NASA heralds it on their website. But critics have long argued that the numbers is wildly inflated by liberals like President Obama who are pushing to control man-made pollution.
