2:00 p.m. -- One of the world's largest food companies says it's about to take a major bite out of global warming. General Mills, the company that manufactures Cheerios, Cinnamon Toast Crunch and Wheaties, said Monday that it will set a target to limit air pollution throughout its entire supply chain by August 2015. This marks the first time the food giant will measurably rein in greenhouse gas emissions from agricultural suppliers of the ingredients used in GM products. And environmental watchdogs say the effort is significant. The targets will align with the goal of keeping a rise in global temperatures below 2 degrees celsius, a standard climate scientists say is necessary to avoid devastating impacts of global warming. -- Clare Foran
