Don't Panic, but I think we should...

Just saw this Horizon progam on BBC2 on the reduction of Global Dimming. We are in deep doo doo, what we need is a radical reduction in carbon emissons or we are all toast. And plant more trees, the ultimate atmospheric carbon remover. And in addition we need to invent a solar powered machine that removes carbon from the atmosphere and put them where the most sunlight is.
