If the Sun is responsible for an increase in solar activity, and hence global warming - then this makes taking action on global warming even more important and urgent.
This isn't some theoretical debate on whether we are affecting the planet, and that we shouldn't - its the actual physical increase in temperature (and the results) that is important.
Otherwise we just sit here and get fried - and in the end just say "Well, it wasn't our fault...".
I haven't done enough research on it, but I can't imagine our global warming trends could be the sole result of increased solar activity. Its simply too obvious, and something that is quite easily measured.
It also seems quite "suspicious" that for the billions of years that the Earth/Sun have co-existed (and a couple of thousand years of recorded history) - its the same 50 years that humans have had a significant impact on our own climate - that the sun has caused the temperature differential (and one that perfectly matches scientific predictions and equations based on AWG).

BTW, elprincipe: your link is broken...
"Here is a chart (http://www.usatoday.com/weather/wcstates.htm) showing record low temperatures. Some are from the 1800s and some from the 1990s."

And Timmah!, reading from your last link on the warming about Mars... here is a section from the article. Basically no one agrees with the guy claiming the sun is responsible for warming:
" "His views are completely at odds with the mainstream scientific opinion," said Colin Wilson, a planetary physicist at England's Oxford University.
"And they contradict the extensive evidence presented in the most recent IPCC [Intergovernmental Panel on Climate Change] report." (Related: "Global Warming 'Very Likely' Caused by Humans, World Climate Experts Say" [February 2, 2007].)
Amato Evan, a climate scientist at the University of Wisconsin, Madison, added that "the idea just isn't supported by the theory or by the observations."
Planets' Wobbles
The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet's orbit and tilt, not by changes in the sun.
"Wobbles in the orbit of Mars are the main cause of its climate change in the current era," Oxford's Wilson explained. (Related: "Don't Blame Sun for Global Warming, Study Says" [September 13, 2006].)
All planets experience a few wobbles as they make their journey around the sun. Earth's wobbles are known as Milankovitch cycles and occur on time scales of between 20,000 and 100,000 years.
These fluctuations change the tilt of Earth's axis and its distance from the sun and are thought to be responsible for the waxing and waning of ice ages on Earth.
Mars and Earth wobble in different ways, and most scientists think it is pure coincidence that both planets are between ice ages right now.
"Mars has no [large] moon, which makes its wobbles much larger, and hence the swings in climate are greater too," Wilson said."

This is a good discussion though, and its forcing me to research and learn more about the related topics... so keep it coming!
