& another quote, this one from the 2004 link:
Dr. Solanki said that the brighter Sun and higher levels of "greenhouse gases", such as carbon dioxide, both contributed to the change in the Earth's temperature but it was impossible to say which had the greater impact.
Nothing's impossible, but I suspect it will take a whole flurry of solar studies to give us a better handle on the extent of solar input into the temperature mean.
Believe me, if I seriously thought Kyoto or vehicle emissions would make a dent in global warming, or even slow it down, I'd go out and lobby for it. Knowing the way the world works, the pollution would just be shifted around to other 3rd world nations anyway and it would just slow the economy of the one nation that has the best chance to find and finance a real solution--and even if these other nations could be coerced to cap most CO2, I still don't think it would make a dent in global warming trends.
Spending time addressing the wrong solution is a waste of time and energy.
We need to grow in many fields. The new supercomputers are promising. Nanotechnology is getting off the ground. Atmospheric research and modeling is finally starting to include the greatest influence on our weather: solar emissions. Twenty years ago we couldn't do almost any modeling because there just wasn't enough data.
In just the past 5 years the solar data acquired through SOHO, alone, is astounding. The high frequency research going on with the HAARP project is also providing good data which will come in handy.
Be patient. The next decade will bring out much data and some long term solutions being proferred to the international community.
