Grist reports on a new Cornell University study testing how consumers respond to three climate-adaptation options for winegrape producers, shade cloth, switching to heat-adapted grape varieties, and relocating to cooler regions. The study found that consumers were willing to pay a premium when these changes were clearly communicated, although relocation was the least desirable option, and the article notes important limits, including a sample of only 300 respondents, mostly younger graduates who already cared about environmental issues and food labels.
