Farmers are becoming more open to acknowledging that carbon emissions and climate change are becoming a problem, according to Iowa State University researcher J. Arbuckle. And it’s a good thing they’re willing to talk about it, as the Intergovernmental Panel on Climate Change (IPCC) states that without cutting carbon emissions, growers will face increasing weather challenges, including severe storms, droughts, floods and pest migrations — problems that could be a major hit to the bottom line.
