>water vapour argument
It's amazing how persuasive this is when used incorrectly. Yes, it is the major greenhouse gas. It's also something that exists as a feedback loop in the environment, whereby when temperatures increase, cloud formation also increases from that water vapour condensing in the upper troposphere, which in turns causes negative radiative forcing, thus cooling the planet again. The plane can also handle carbon dioxide and methane, if given time, through ocean sedimentation and oxidative destruction of CH4. 

The point you are missing with your graph is that a sharp, swift increase in GHGs like carbon dioxide are enough to raise the temperature without any known feedback loop to remove the extra CO2 and CH4 (not to mention N2O, which is even worse in this regard due to it's long lifetime) from the atmosphere. 

If you want an analogy, imagine the tiny quantities of arsenic in your body. As posions go, it's dwarfed by the quantity of other toxins within you. However, rapidly increasing the arsenic in your body by even a smll amount will have a bad effect on you. Does this make sense to you?


gr8 argument. 

Seriously incomprehensible to me why so many of you seem to love the idea of greedy kikes raping the planet for their own profit. Is it because lefties are currently using the issue to ram through their own agenda, and because you hate lefties you must hate the evidence that they're currently abusing to get what they want? How about just being a conservative for once and stadning by the simple, moral principle of not fucking over our envirioment to enrich amoral bastards?
