What's truly remarkable when you think about it is how all these self - regulating heat engines work together to produce such a remarkably stable climate that sometimes persists in more or less the same steady with no major perturbations for tens and hundreds of millions of years at a stretch.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

Back in the olden days, in the days when they had the sort of «stable» climate we are all now expected to aspire to, long before anyone had thunk up global warming or anything, they used to amuse themselves of an evening by singing about how natural variability is always going to happen whether the models be right or wrong.
