I just received two copies of a newsletter called Cool Foods: Countdown to Copenhagen & Beyond from the Center for Food Safety. The purpose of the effort is to remind negotiators and the public that industrial agriculture accounts for between 13.5 percent and as much as 32 percent of greenhouse gas emissions. "Particularly alarming," they write, "is that industrial agriculture is responsible for 60 percent of total global nitrous oxide emissions, largely from nitrogen fertilizer. Nitrous oxide is the deadliest of the three major GHGs, approximately 300 times more potent than carbon dioxide." And on in the same vein. Scary but vital information.

Lester Brown’s Earth Policy Institute has a somewhat different take on the subject, but also provides compelling evidence and argument that climate change and agriculture are intimately linked.
