If global warming is caused by increased emissions of carbon dioxide resulting from human industrial activity, as opposed to increased solar activity, why is Mars warming at a rate four times faster than the Earth?
I do realize that correlation does not imply causality, but if there is no causal link between the warming of the Earth and the warming of Mars, there must be some other explanation for the warming occurring on Mars. And before anyone points out the effect wind storms are having on Mars, let me point out that wind occurs when air in one region becomes warmer than air in another region and air moves to reestablish thermal equilibrium. The sun heats the Martian atmosphere just as it heats the Earth's atmosphere. If the sun is more active, the areas of the Martian atmosphere exposed to the most sunlight will become warmer relative to the areas that receive less sunlight than they otherwise would be. This greater temperature difference between regions leads to more severe windstorms, which then kick up more dust, reducing the albedo effect discussed in the story.
It may well be that man is largely responsible for global warming (though I very much doubt it), but in order to establish this, increases and decreases in solar activity must be conclusively shown to have little to no effect on climate.
