What is the real problem?

Can't blame the Sun
One of my assertions that my friends have heard many times is that the Sun is in a violent period right now. Within the last few years more gigantic X class flares have been recorded than anytime previously. I even found a German paper that documented solar activity and shows that the Sun is about 15% brighter at some frequencies than twenty years ago. Of course, mankind has not had the instrumentation to measure and monitor solar flares for more than a couple of decades. Proxy measures such as the measurement of isotopes of beryllium in Greenland ice in fact suggest that fantastically more energetic solar flares have occurred within mankind's history.
Total irradiance of the Sun, though, has varied only 0.1% over many 11-year solar cycles. This doesn't seem like much, but the ice caps on Mars are disappearing. Some interaction between the planets and the Sun is occurring that we do not completely understand. UV from the Sun varies by factors of 2 to 10 times over the course of a Solar cycle. That the Martian ice caps are melting and subliming suggests the Sun sways our climate much more than previously thought.
I am not professional climatologist, and I'm being presented with conflicting views and evidence. Scientists generally attribute only small variations in climate to the Sun because of small variation in irradiance, but the Martian ice caps are melting. The Northern hemisphere suffered a miniature ice age in the 1600s to 1700s, a time that corresponds to diminished solar activity, called the Maunder Minimum. The current Martian icecap melting and the Maunder Minimum means the generally held view of scientists that the Sun's variations don't affect us much is just plain wrong.
On top of that, the Earth is just now coming out of an ice age. Even if it weren't for greenhouse gases the Earth would still be getting warmer.
Despite apparent evidence that Sun is playing a larger role in global warming than the general scientific community seems willing to admit, that should not influence our policies on global warming and the control of greenhouse gases. If the planet is warming for any reason it seems colossally stupid to exacerbate it with greenhouse gas production.

Introduction: The World is Not Ending
Our problems are interlinked, and so are the solutions. We must expand our thinking from just the passive to the active. In addition to reducing carbon dioxide emissions we also develop oil-free methods of producing energy, and the means to extract the excess carbon dioxide from the atmosphere. Not only can we stop damaging the planet, but we can also repair some of the existing damage, free ourselves from the threat of terrorism, and rescue civilations from despotic regimes.
Much of the debate about global warming lacks solid data, or data that is too easily mis-interpreted. Some assertions are just plain wrong. Global warming is occurring, but not all of the warming is due to industrial causes, and the major part of the industrial causes would be surprising to most people.
My blog documents my exploration of the assertions surrounding the crises of the world. I do not agree with the Bush administration, but just as strongly I do not agree nor believe all of the assertions of Al Gore. I have been tracking global warming since 1977. In the 1990s I worked on proposals for NASA's mission to planet Earth series of satellites, including a heat budget satellite to establish the baseline for the study of global warming.
Even if global warming is not entirely due to industrial output of greenhouse gases, it seems really stupid to dump more into the atmosphere while the Earth is warming.
Wish us all good luck and success in this endeavor.
