It's not often you hear of good news on the fight against climate change. I haven't even blogged here about the disappointment in international negotiations at the moment.
But hot off the presses at TIME magazine comes a story about biochar. No, I hadn't heard of the stuff either.
It's a very simple process that can be done anywhere, in which organic material is burnt in a way similar to how you make charcoal - that is, with very little oxygen. The result is that the material actually takes up carbon dioxide, rather than releasing it. The biochar can then be used very effectively as a fertilizer, so it can also save on CO2 that is normally produced by making artificial fertilizers.
On a big scale, this stuff could be the future.
