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.

While actual scientists are trying to piece together every little part of an otherwise almost un-piecable long term chaotic and variable system in response now to a massive increase in net lower atmospheric energy absorption and re radiation, Curry is busy — much like most of the comments on this site most of the time — trying to come up with or re-post every possible argument under the sun to all but argue against the basic concept that radically altering the atmosphere on a multi million year basis is going to affect the net energy balance of earth, which over time is going to translate into a very different climate (and ocean level) than the one we've comfortably come to rely on.

For the latter, one merely has to demonstrate either of two things: that CO2 does not indeed alter the thermal budget of the climate system such that increasing its concentration results in the trapping of more heat within that system, or that the negative feedbacks associated with CO2 - induced warming overwhelm the positive ones and result in a neutral or negative change to the state of the climate's average temperature.
