Please don't bring that politicized stuff into the discussion. That's a different flame war entirely.

If Jupiter is warming/cooling or Mars is warming/cooling, then something has to be responsible for it, and it sure isn't human activity.

If not the sun, then what? Something about planetary environments we're likely interested in learning more about, right?

You don't get to just label contrary scientific findings as 'political', and dismiss it out of hand. Here's the published paper that the article refers to: http://iopscience.iop.org/1748-9326/3/2/024001/ The correlations don't hold up under analysis, and that's really all there is to be said on the subject. But if you feel that you can refute that paper with evidence, then go for it. I for one would love for you to be right, It's no doubt save me (and everyone else on the planet) a whole load of economic pain. Sadly, reality does't seem to be going along with my desires.

I didn't dismiss/refute/claim anything or intend to start yet another global warming flame war. I'm probably as familiar with that research as you are and I'm not refuting it.

If other planets are warming/cooling then something is responsible for it. If it's not the sun, then it's something else related to planetary environments with which we are not familiar. Studying that would be A Good Idea, regardless of where people stand on global warming, because examining Earth alone just gives us a single data point.

What's happening on Mars? Does it parallel the changes we're seeing on Earth to some degree? What's happening in Jupiter's atmosphere to bring about such a dramatic change in a short period of time?

Could we see a similar dramatic change on this planet?
