- greenfyre, on 08/13/2008, -0/+2and where did I say this was evidence of current instability? I think if you actually read what I wrote I am very clear about what point it is meant to make ... it's right there in English ... try reading it.
As for the evidence of our current state, I am happy to post it again, and you will not even look at it again, and pretend that somehow you know better.
OTOH this could be your chance to make me eat my words by actually looking at the evidence and saying something rational and relevant ... are you up to the challenge?

The "runaway greenhouse" occurs when there is a sudden increase in GHGs, not when they have stabalised at whatever level.
Historically rapid changes in climate have led to mass extinctions;

which smart people view as something to be concerned about. - BigManOnCampus, on 08/13/2008, -2/+1Only a fool would attempt to use evidence of the effects of rapid changes to demonstrate that Earth's greenhouse effect is in an unstable state. That's like picking up the pieces of broken glass from a car accident and saying "See, your brakes are about to fail."
- BigManOnCampus, on 08/13/2008, -2/+1Only a fool really believes there is a "tipping point" that we are somehow close to. Only a fool believes that the Earth is in some sort of "unstable state" that more CO2 in the atmosphere will disrupt.
-- CO2 has been in our atmosphere in much higher concentrations in the past due to volcanic activity.
-- There was no runaway greenhouse effect then.
Hence there will be no runaway greenhouse effect now.
