About rice reduction potential versus other anthropogenic emissions - Eileen Matthews tells me that some of the estimates of potential CH4 emissions reductions in the various studies over the last decade by EPA's M2M program/GMF/GMI are exaggerated, she feels sure. But as I mentioned to her, their

This raises the question of whether routinely adding SO4 ions to fertiliser aimed at being used on rice paddies would be a good idea. I can see an obvious reason why it wouldn't be sensible, although the intermittency of addition may be an issue. Maybe sustained-release granules can be developed?

Hi, Andrew - I was mentioning this issue a few days ago, based on a meeting with Elaine Matthews at GISS who was involved in the original research. as I said, it's also a reason why plain old ground-based sulfur emissions might be a good idea, in this relatively uninhabited region. Here's
