To be honest, I don't know what to make of the global warming debate, or even if there should be a debate, or whether it is settled science, and there are just a bunch of oil-funded denialists disputing it. However, I found this graph intriguing. If it is accurate (is it?), then whatever global warming taking place right now seems rather minor, and not necessarily related to CO2 in the atmosphere. But perhaps the experts have an explanation for it all.
