Shooting Sunfish In A Barrel

"If the shooting of fish in barrels offends you, look away."

Warns Nature columnist Oliver Morton, of his inquiry into "The sceptical 'argument'...that global warming on Earth should be seen as a natural, as opposed to anthropogenic, phenomenon "because of  temperature changes on uninhabited planets erstwhile skeptics attribute to solar variability by default.

"This idea... regained a certain prominence in February when...National Geographic's website dredged up the belief of a Russian astronomer, Habibullo Abdussamatov, that the warming on Mars shows that the Sun is driving climate change on Earth."

The problem with this  Op-ed chestnut is that solar heating falls off with the square of planetary distance. So  a 1 degree increase in Neptune's temperature requires a vastly greater change in solar output than  does warming the Earth by 1 degree. About 29% to be exact. You would think solar cell salesmen would have noticed a 100 watt per square yard change , not to mention Coppertone copy writers.

I am not sure I understand what you are saying here. I understand that the fact that much of the solar system seems to be warming is not proof that the sun has increased output. But isn't the point here that it is certainly not evidence that supports the idea that humans are causing global warming?
