Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

Regarding the evolution of Solar Activity during past years, it is indeed awkward to relate a possible warming in Mars with it.

Another important note to make is that the theory  closer to draw a link between Solar Activity and the Earth's climate, Cosmoclimatology, is founded on  galactic cosmic ray effects on cloud formation. Now, clouds is something Mars doesn't have...

Mars does have clouds (IIRC both H2O and CO2 ice clouds), they are just not as important for climate as on the Earth.

In fact, you see lots of clouds (most of it morning mist) on the photo in the diary.

Then again, Mars doesn't have a bipolar magnetic field, so solar magnetic activity changes cosmic ray influx only locally and in minor ways.

Oh, and in Mars's case, I guess the fluctuation of solar radiation they mean is not the miniscule variation in the Sun'S luminosity, but the effect of distance: the eccentricity of Mars's orbit not being negligible.
