Sam..
So how can you explain the melting of the Martian icecaps, if not due to additional solar radiation due to sunspot activities?
And btw, Mar's atmosphere is significantly comprised of CO2, so shouldn't the entire planet be one huge greenhouse if the theory that CO2 was responsible for such a condition? The fact that it isn't suggests that Mars is lacking something else (see final question at the end of this post for the answer).
Additionally, if there is a "greenhouse" effect, then the Troposphere should be warming up as solar radiation is trapped at that level BEFORE the surface warms (top down convection of trapped heat). Current tropospheric temperature increases appear to be LAGGING surface temperature increases.

From 1645 to 1715, there was a drastically reduced number of sunspots. This period of reduced solar activity, which was first noticed by G. Sporer and was later investigated by E.W. Maunder, is now called the Maunder Minimum. This period of time was also unusually cold on earth, and it has been referred to as the "Little Ice Age." This has led to some speculation that sunspot activity may affect the earth's climate. Similar periods of low solar activity seem to have occurred during the Spoerer Minimum (1420-1530), the Wolf Minimum (1280-1340), and the Oort minimum (1010-1050). Solar astronomers label solar cycles from one minimum to the next, and assign them numbers, starting at one, with the 1755-1766 cycle.
Now take a look at this graph and tell why CO2 is a TRAILING indicator that LAGS the actual global warming trend? And why is it that observed Sunspot activity almost DIRECTLY correlates with that global warming?

It DIRECTLY demonstrates that CO2 increases LAG temperature increases.
I'm not saying that temperatures haven't been increasing. But just like medicine, you'd better make sure you're not treating the symptoms instead of the cause. And CO2 increases is a SYMPTOM as that chart clearly displays.
Now... combine this with the fact that current sunspot activity is at the highest levels traceable over the past 1,000 years (either via direct observation, or particle analysis):

And as one final question, I'll ask you this. Which is a greater greenhouse gas.. CO2 or Water Vapor?
