I think you need to look at the temp data long term and short term.
We have been cooling for the last 12 years...
and if you wish to go back to the industrial revolution...
using the best statistical tests... there is no discernable warming outside natural variation.
So even if there is a little warming...
the recent studies have shown it is clouds which most likely cause the variations.
Co2 is a minor part of greenhouse gasses.
man made co2 is even smaller than that.
CO2 has been going up...
over the last 17 years temps have not gone up.
So the models saying co2 forces temp have failed.
What science do you have showing man made co2 causes warming on earth...
answer... all you have is a guess.
could your guess turn out to be true... yes..
Is man made co2 likely to be a major factor in warming...
no... why...
because it also does a lot of cooling in the upper atmosphere.

Quote from Hoofhearted:
It would be harder to prove that man made co2 isn't causing global warming, or that its affect is probably only small and insignificant, as you believe.
There is new research being done with core samples taken from various spots on the globe in which we are examining climate history.
It may very well point out that this may be the only time in earth's history when climate has changed so drastically in such a short period, without being accompanied by a global natural event, such as volcanism, or meteor impacts.
If this turns out to be the case, it would be hard to argue that man made co2 isn't the cause of such a rapid change.
Or What else do you think could cause such a sudden shift?
It could perhaps be a more prevalent emergence of one of the other greenhouse gases, but What would be causing that, and Which gas is the culprit?
It could also be that we are still new at testing our fancy gauges that determine heat, distance and other astronomical factors.
Maybe after a few more decades or centuries we will see that our orbit shifts or wobbles on a longer scale, or that the sun's and other stars' energy output may have natural fluctuations that we are currently unaware of.
It's pretty certain for now, though, that barring ancient advanced civilizations and unknown ancient life forms, that at no other time in history has so much co2 ever been pumped into the atmosphere by one species on a yearly basis.
Seems awfully coincidental that the Earth's temperature is rising too.
