Man - caused Global warming is not science.
To be science, it must follow the scientific meathod
http://en.wikipedia.org/wiki/Scientific_method
in essence,
to observe a condition
develop a hypothesis
to prove the hypothesis
Global warming caused by man is nothing more then 100-150 years of circumstantial evidence without a provable link... anywhere.
Myth- Global warming is caused by pumping of additional CO2 into the atmosphere that was not previously there; as created to a vast amount since the industrial revolution.
Fact - C02 is a large part of the earth's, and Martian atmosphere (95% Mars)
Mars itself has had a sustainable and repeatable value of C02 in its atmosphere wholey and completley absent of the controls of Man, minus a rover, or two, and a few Viking landers. Yet, Mars is experiencing it's own global warming!

"One explanation could be that Mars is just coming out of an ice age," Feldman said. "In some low-latitude areas, the ice has already dissipated. In others, that process is slower and hasn't reached an equilibrium yet. Those areas are like the patches of snow you sometimes see persisting in protected spots long after the last snowfall of the winter."

Which I find interesting in that We have no relation whatsoever in what happens there! I find myself wondering what both Earth, and Mars have in common? What could be causing these temperature increases on our planet, and our celestial neighbor?

The sun in fact does affect the Earth directly... as do the Sun's conditions and patterns... which can clearlly be seen as an increasing ferocity of Solar activity here
But although the Sun is known to be a variable star, its total output of radiation is often assumed to be so stable that we can neglect any possible impacts on climate. Testimony to this assumption is the term that has been employed for more than a century to describe the radiation in all wavelengths received from the Sun: the so-called "solar constant," whose value at the mean Sun-Earth distance is a little over 1 1/3 kilowatts per square meter of surface.
In truth, the solar "constant" varies. Historical attempts to detect possible changes from the ground were thwarted by variable absorption in the air overhead. Measurements from spacecraft avoid this problem, and the most precise of these, made continuously since 1979 (Fig. 2a, b), have revealed changes on all time scales--from minutes to decades--including a pronounced cycle of roughly eleven years.
.........
New insights into the variable nature of the Sun have almost always been followed by efforts to find possible impacts on the Earth--chiefly through comparisons with weather and climate records. Initially the quest was not so much a detached inquiry as a determined effort to demonstrate a long-sought hope: that keys found in the cyclic nature of solar behavior might open the doors of down-to-Earth predictions.
In the latter part of the 19th century, there were many claims of new-found connections between sunspots and climate. It began with the announcement by the amateur astronomer Heinrich Schwabe, in 1843, that sunspots come and go in an apparently regular eleven-year cycle. What followed was a flood of reported correlations, not only with local and regional weather but with crop yields, human health, and economic trends. These purported connections-- that frequently broke down under closer statistical scrutiny--lacked the buttress of physical explanation and were in time forgotten or abandoned.

"We're in the maximum phase of the solar cycle now," says Dr. David Hathaway, a solar physicist at the NASA Marshall Space Flight Center, "and it will probably persist for another year or more. This one is somewhat smaller than the last two maxima in 1989 and 1979, but it's definitely bigger than average."

we also find perhaps the reason for our recently frigid temperatures? We are dipping into a Solar low period after a traditionally very intense Solar Max! Maybe this is why so few Hurricanes hit this year? Maybe this is why Glaciers in the southern poles are expanding, while sea levels are falling?

What it means
Contrary to all the horror stories one hears about global warming-induced mass wastage of the Antarctic ice sheet leading to rising sea levels that gobble up coastal lowlands worldwide, the most recent decade of pertinent real-world data suggest that forces leading to just the opposite effect are apparently prevailing, even in the face of what climate alarmists typically describe as the greatest warming of the world in the past two millennia or more.

and yes, the seas' are falling, not rising!
http://news.bbc.co.uk/2/hi/science/nature/5076322.stm
[quote]Arctic sea level has been falling by a little over 2mm a year - a movement that sets the region against the global trend of rising waters.
A Dutch-UK team made the discovery after analysing radar altimetry data gathered by Europe's ERS-2 satellite.
It is well known that the world's oceans do not share a uniform height; but even so, the scientists are somewhat puzzled by their results.
Global sea level is expected to keep on climbing as the Earth's climate warms.[/qoute]

In the early 1990s, scientists forecast that the coral atoll of nine islands - which is only 12ft above sea level at its highest point - would vanish within decades because the sea was rising by up to 1.5in a year. However, a new study has found that sea levels have since fallen by nearly 2.5in

The consensus of global warming scientists is that the sea level won't rise by 20 feet, or even 5 feet. Instead, they predict seas will rise by at most 23 inches, and as little as 7 inches. And even that will take 100 years to occur. That's not nothing, but it's hardly the sort of thing that would suddenly displace millions of people. [reference to Al Gore's film]
In the late 1970s, scientists were predicting a 25-foot sea level rise from global warming. By the mid-1980s, the consensus had dropped to about 3 feet. The U.N.'s Intergovernmental Panel on Climate Change report from 1990 put its "best estimate" for sea level rise at 25 inches. By 1995, that dropped to 19 inches.
And if you take the midpoint from the latest U.N. report, the prediction now rests at 15 inches between now and 2100.

As we see, when the Global Warming supporters put a date on anything where we can actually see feel, and notice results, they will fail each time... so now they have extruded something that may be beyond our lifetimes!
So, let us now delv into the history books, and look at the events that allowed the Vikings to inhabit Greenland, and the English to grow vinyards for wine; and the later stunt in growth, drop in world population, and storied winters...
Global Warming: CA 950-1100 AD, and the mini-ice-age 1300-1900 AD

Global warming is not so hot:
1003 was worse, researchers find
By William J. Cromie
Gazette Staff
The heat and droughts of 2001 and 2002, and the unending winter of 2002-2003 in the Northeast have people wondering what on Earth is happening to the weather. Is there anything natural about such variability?
....
They checked investigations of cores drilled out of ice caps and sediments lying on the bottom of lakes, rivers, and seas. They examined research on pollen, tree rings, tree lines, and junk left over from old cultures and colonies. Their conclusion: We are not living either in the warmest years of the past millennium nor in a time with the most extreme weather.
......
From 800 to 1300 A.D., the Medieval Warm Period, many parts of the world were warmer than they have been in recent decades. But temperatures now (including last winter) are generally much milder than they were from 1300 to 1900, the Little Ice Age.
To come to this coclusion, CfA researchers, along with colleagues from the Center for the Study of Carbon Dioxide and Global Change in Tempe, Ariz., and the Center for Climatic Research at the University of Delaware, reviewed more than 200 studies of climate done over the past 10 years. "Many research advances in reconstructing ancient climate have occurred over the past two decades, so we felt it was time to pull together a large sample of them and look for patterns of variability and change," says Willie Soon of CfA. "Clear patterns did emerge showing that regions worldwide experienced higher temperatures from 800 to 1300 and lower temperatures from 1300 to 1900 than we have felt during our lifetimes."

If anything, we may be aiding in the slow-down of Global warming via the particulates released...
http://en.wikipedia.org/wiki/Global_cooling
In conclusion.... might we find it ironic that there is so much hype when so much data shows us that we are in continual flux, and that we have little to no affect on the weather, and we are in fact quite insignificant?
I am not sure anybody could believe in Global warming after all this... but thatts just my opinion. Sorry for the OT
