We now have similar temperature graphs for Mars, Neptune, and the Earth. All correlate with Solar Output.
There are two ways of interpreting this:
1. That Global Warming is all the fault of the Sun, and that Man's impact is immeasureably small in comparison - so we should do nothing.
2. That the place is warming up anyway from natural causes, so adding Greenhouse gasses and making the situation no better, probably worse, possibly much worse, is a Bad Idea (tm).
Basically the whole thing is so politicised that we really need to get more and better data on how Man's actions are affecting the climate before we do anything. It's even possible we're ameliorating rather than worsening the situation through feedback effects.
