It was 8 degrees in Minneapolis on a recent January day, and out on Interstate 394, snow whipped against the windshields of drivers on their morning commutes. But inside the offices of Cargill, the food conglomerate, Greg Page, the company’s executive chairman, felt compelled to talk about global warming.
“It would be irresponsible not to contemplate it,” Mr. Page said, bundled up in a wool sport coat layered over a zip-up sweater. “I’m 63 years old, and I’ve grown up in the upper latitudes. I’ve seen too much change to presume we might not get more.”
Mr. Page is not a typical environmental activist. He says he doesn’t know — or particularly care — whether human activity causes climate change. He doesn’t give much serious thought to apocalyptic predictions of unbearably hot summers and endless storms.
