What does that graph show Photon? How can the heat be negative? I understand there can be less heat than a certain average period; but if that's the case how can there be more heat in 2008; when 2008-2012 is what the blue line shows.
I ask because I don't understand; not trying to be confrontational.
It's actually some of these graphs that I think work against getting people to understand what CC is all about. I know one posted earlier shows a temperature increase; but the flat line of the early 20th century has one notch per degree, then after 1970 1 notch shows .2 degrees or something. Meaning the graph shows a spike; but the spike isn't to scale.
