Folks, the answer to climate change is found 93 million miles away. C02 has been as high as 250,000 ppm in the past. It is currently about 380ppm. Most GW fanatics say it should be below 350. Plant growth stops at 200 and below. Its happened in the past. The Maunder solar minimum devestated most of the population in the middle ages and later the Dalton solar minimum hit from 1780 to 1830.
Astrophysicists say 1000 ppm is optimal for plant growth.
Another thing to consider is that in the cycle of climate changes, a warming period has been historically good for flora and fauna while cooling trends have been near extinction level events.
The earth remains in a period of deglaciation (I hope) and technically, an ice age.
The minute warming detected (although questionable) ceased in 1998 and we have just emerged from a deep solar minimum between cycles 23 and 24. If (and I hope not) the minimum from 24 to 25 is as long, the planet could be shortly in another chill down.
What can we do to stop it? Nothing, but at this point with the possibility of climate induced famine looming in the future, why are we using every crackpot theory coming and going to raise energy costs and curtail supplies? The answer could only be the INTENTIONAL neglect of population's welfare.
The study's key conclusion was to show that the ratio of small soil dust particles (clay), which cool the atmosphere, to large soil dust particles (silt), which yield an indirect heating effect, may be much higher than previous estimated. This is a critical finding because it shows that the Earth's climate may be much more sensitive to solar radiation than previous models have indicated, which in turn casts doubt on anthropogenic warming theory -- the idea that human carbon dioxide emissions bear the primary warming influence on the climate over the last several decades.

A computer model is only as good as the input you put in.

Its in the history books! Google search Maunder , Dalton Minimum. Or don't. I don't care. It won't change a thing. What does change things is raising energy costs for no better reason than some sort of fanciful whim. It may be an inconvenience to modernized nations but causes millions to perish in third world countries.
Just saying that I'm wrong on every count doesn't make me wrong. The climatory record of C02 levels is well documented as are the effects of solar cycles on global temparture.
You all are hanging the blame for something your not even sure exists on a gas that merely makes up about .04% of the atmosphere and of that small percentage, humans contribute about 3%. The first 20 ppm greatly affect and help regulate temperature but the affect decreases as the levels increase.
An example came during the Maunder minimum when temperature levels reached dangerously low levels. Tree growth slowed so much, the rings of some species ended up so close together that the Stradovarious violen crafted from them is worth millions today. The close grain of the slow growing wood made for an unimitatable sound.
The bad thing is, most of the population of Europe froze/starved to death.

Also, to tell someone who says that the sun has an effect upon temperatures on earth that they are wrong on every count goes way on past "drinking the coolaid" as they say. I hope you know that.

yes and every other plannet in out solar system is warmer too. I guess man caused that too? whats wrong with drudge?

I am 50 years old and have learned through my training here on Earth that if they say look left, I instinctively look right. They said we were running out of fossil fuel, I went out and bought a second vehicle.
They said man-made Global Warming, I said get out your mittens.
I am not part of any problem for I don't think pollution has ANYTHING to do with Global Warming.

You are doing what the government really wants, to ignore what we are doing to our planet so the capitalist economy can keep raping it and destroying it's eco system.
The Kyoto Protocol calls for mandatory carbon dioxide reductions of 30% from developed countries like the U.S. Reducing man-made CO2 emissions this much would have an undetectable effect on climate while having a devastating effect on the U.S. economy.
Such drastic measures, even if imposed equally on all countries around the world, would reduce total human greenhouse contributions from CO2 by about 0.035%. This is much less than the natural variability of Earth's climate system!

To answer your questions: No. I do not think the Global Warming Theory figures in solar cycles, in fact those espousing it have gone out of their way to deflect any discussion concerning its impact.
Second, the last decade was not even close to being the warmest on record. The Vikings once farmed Greenland before the Maunder minimum. Third, even pro global warming grant collectors are having a tough time explaining why there has been no warming since 1998. Once again, you confuse reality with model projections. Thats been the problem all along. Quoting model predictions as reality is a misnomer. Since the 1970's we have had the equipment to make real-time observations so lets use those, shall we.
And lastly, the Maunder minimum was not a 30 year absense of sunspots. It was deep minimums on the end of two cycles which had lasting and reverberating effects. You didn't mention the more recent Dalton Minimum which last approx 1780 to 1830 and had global climate affects.
You never addressed my point that civilizations have historically thrived during warming trends and suffered during the opposite other than to give me a blanket "wrong" on all my points but I assure you, that is the case. We know the famine in Europe which brought about the Plague happened during a cooling period (Maunder) and also the Vikings, who were diriving about 70% of their food from agri/horticulture in Greenland 25% from the Sea and 5% from shipments via their homeland. During their demise, this reversed and as the sea ice closed in, their fish left and their route to home was closed off. They withered.
It happens that easy. Folks, we all take for granted that come what may, those trucks will still deliver to your local grocery but that is dead wrong. If (and its an if I do hope I'm dead wrong about) if the growing seasons in the nation's bread basket shorten to the point that crops are damaged before they are ready to be harvested, I guarantee those trucks won't run.
I know that many people on this board have grandious ideas of survival on their own but I tell you all here and now, its a hell of a lot better to just dream about it than to have to live it. Its tough to grow every bite you eat and even tougher to keep what you grow during a famine.
Our current solar minimum's effects have already become apparent. The minimum allows more cosmic rays to evaporate moisture, increasing cloud cover which reflects sunlight. On the front end, more precip, more cloudy days. On the back end, a deep freeze.
The good thing about this is that we won't have to wait 100,000 years to see if the ocean rises an inch. If this is the case, it'll shortly become apparent and we won't worry much about what happens on some internet message board. If it doesn't and we return to a warming trend, you all can go back to hitting the panic button and I'll gleefully enjoy being wrong albeit well fed.
