Claim
This is one form of the global warming is caused by increased solar radiation myth. It is basically the same as the Mars is warming irrelevancy; they are often mentioned together.
Reality
Aside from the fact that Pluto's warming has not been correlated with increased solar radiation, it should be noted that Pluto's orbit is a far greater factor in its current temperature than any likely changes in solar output could ever be. Pluto's orbit is highly eccentric and lasts 247 years, so it should be expected to have warming trends that last for about 223 years as it approaches the sun, each followed by a cooling trend that lasts for about the same. We are now seeing one such warming trend.
