Solar warming is a small factor in Earth's change, and a larger one elsewhere in the solar system.
Data. Solar variation is 0.12 watts per meter squared. Man caused warming is 1.6 watts per meter squared, more than ten times as much. Page 4 of this report, which is based on a mountain of peer reviewed data.

Here is what scientists think (because of the data, not because of brilliant insight):
"While evidence suggests fluctuations in solar activity can affect climate on Earth, and that it has done so in the past, the majority of climate scientists and astrophysicists agree that the sun is not to blame for the current and historically sudden uptick in global temperatures on Earth, which seems to be mostly a mess created by our own species."
The source is not exactly the liberal media:

Try to keep up with science will ya'!
1. Pluto is no longer considered a planet.
2. In any case it takes Pluto a lot longer to circle the sun, its seasons are years longer than on Earth, per the very link you provided:
"Pluto's orbit is much more elliptical than that of the other planets, and its rotational axis is tipped by a large angle relative to its orbit. Both factors could contribute to drastic seasonal changes."
No I don't think Pluto is getting warmer because of fossil "fools", duh!

No it's caused by seasonal variations. The exact same thing that makes it warmer in summer and colder in winter here on earth.
For some reason the global warming skeptics have latched onto this (along with similar warming on Mars) as being some sort of reason to rebutt global warming on earth. The problem is, what's happening on the other planets is precisely what would be expected, what's happening on earth isn't what would be expected.
The global warming skeptics haven't been able to find any evidence to dispute global warming on earth so they make it up or, as in this example, misinterpret it to suit their own ends. Sad really.

fist off, pluto isnt a plantet anymore :( it didnt reach he qualifications, they actually made it in to a saying now pluto meens not good enough! i found it pretty cool. But I think that is one possibility, a good one. But without further research the options are endless, it could just be a natural thing, the universe is fulll of wonders!
