Scientists Split on Human Impact on Climate Change

BY:

A Purdue University survey shows that the scientific community is split on the question of whether human activities are at the root of climate change, with just over 50 percent of scientists saying that climate change is happening and that it is "caused mostly by human activities."

The Media Research Center reports that the study's findings differ largely from the often used statistic that 97 percent of scientists believe in man-made global warming.

Rather than claiming 97 percent of scientists believe in man-made global warming, hopefully now some media outlets will revise that number closer to 50 percent.

Contrary to the repeated insistence of both climate alarmists and the media, scientists do not all agree on the standard climate alarmism talking points. A Purdue University scholar, surveying scientists in the agricultural sector including climatologists, found surprising disagreement on humanity’s role in climate change. These findings, though contrary to popular narrative on climate change, are unsurprising to anyone familiar with the prevalence of dissent in the scientific community. […]

This evidence is inconvenient to the many media outlets that have endlessly repeated that 97 percent of scientists endorse the global warming hypothesis. Prominent outlets like NBC and the New York Times, as well as countless others, have effectively shut down debate by asserting there is no scientific debate.

The Purdue study was done to compare opinions on climate change from scientists, climatologists, and the agricultural industry. Only 53 percent of climatologists said that climate change is caused "mostly by human activities."

The number of scientists and climatologists that chose this option is still high when compared to agricultural advisers (12.3 percent) and farmers (8 percent). The majority of both agricultural advisers and farmers said that "climate change is occurring, and it is caused more or less equally by natural changes in the environment and human activities."
