Study: Farmers and Scientists Divided Over Climate Change

Crop producers and scientists hold deeply different views on climate change and its possible causes, a study by Purdue and Iowa State universities shows.

Associate professor of natural resource social science Linda Prokopy and fellow researchers surveyed 6,795 people in the agricultural sector in 2011-2012 to determine their beliefs about climate change and whether variation in the climate is triggered by human activities, natural causes or an equal combination of both.

More than 90% of the scientists and climatologists surveyed said they believed climate change was occurring, with more than 50% attributing climate change primarily to human activities. In contrast, 66% of corn producers surveyed said they believed climate change was occurring, with 8% pinpointing human activities as the main cause. A quarter of producers said they believed climate change was caused mostly by natural shifts in the environment, and 31% said there was not enough evidence to determine whether climate change was happening or not.

The survey results highlight the division between scientists and farmers over climate change and the challenges in communicating climate data and trends in non-polarizing ways, Prokopy said.

Currently, agriculture accounts for 10-12% of the total human-caused greenhouse gas emissions globally. Focusing on the causes of climate change, however, is likely to polarize the agricultural community and lead to inaction, said study co-author Lois Wright Morton, professor of sociology at Iowa State University. To foster productive dialogue, she said, scientists and climatologists need to “start from the farmer’s perspective.” S
