Climate Change Minister, Penny Wong and Agriculture Minister Tony Burke are expected make an announcement on soil carbon this Saturday. Soil carbon has been talked about as being the silver bullet for carbon sequestration but I've yet to see anything other than wishfull thinking to back this up, yes there is potential but the figures seem to me to be wildly optimistic. The Libs had latched onto it a while ago (no doubt trying to appeal to the rural vote), Labor looks set to do the same. We shall wait and see what they come up with.
