When it comes to reducing greenhouses gases, every little bit helps, and that includes managing the greenhouse gases produced by how we grow our food. Raising livestock and growing crops both generate greenhouse gases, and to gauge their impact, a new study takes the long range view. The results were published in a paper: “Measuring and mitigating agricultural greenhouse gas production in the U.S. Great Plains, 1870-2000” in the Proceedings of the National Academy of Sciences. It analyzes 100 years of agricultural production, and it takes this look at farming close to home – it focuses on the bread basket of the United States – the Great Plains, which includes eastern Colorado. Here to tell us more are scientists Myron Guttman (University of Colorado) and Bill Parton (Colorado State University)

Real Food (start time 4:20): What we eat , and how we eat, is inextricably connected to our own health as well as the health of the planet. Every decision we make—whether to bake a chocolate cake or buy it from Safeway or at a Farmer’s Market—is full of nuances and even contradictions. 
An educator and perfomer, Len Barron first developed a piece about Einsteina and Bohr as a one man show, but then decided to evolve the project by enlist the help of 8 grandmothers to tell the story with their own added pizazz. Not only was lively performance produced, but a process and experience was shared. This process was captured by documentary film maker Robin Truesdale in a film coming to the Dairy Center this weekend entitled A Beautiful Equation. Both Robin and Len have joined us today in the studio to tell us more about the film, the process, the scientists and the grandmothers.
The Science of Humor (start time: 14:32): Have you ever laughed at something you know you shouldn’t have? Like when someone you know falls down the stairs?
