carbon tax impact on coal, page-34

actually I think what the analysis means is that since we're in some sort of sun spot cycle right now, the world seems cooler (artificially) than it should be.

plus the fact that temperatures have risen over the past 50 years due to the greenhouse effect.

I think this means that when the sun goes back to "proper" output (i.e. higher energy output) the additional energy PLUS the greenhouse effect of man made carbon dioxide will produce greater temperature rises than currently seen.

.... makes sense to me
