Response # 2: A different (probably equivalent, but I find it easier to understand) explanation is that the stratosphere is heated by absorbing solar / uv by ozone; increasing the amount of CO2 (which is only significantly active in the IR) increases the ability of the stratosphere to lose heat, so it does.

The transport processes are also very variable from winter to winter and the amount of ozone pumped into the Arctic is also correlated with temperature (this is not a causal relationship — the correlation exists, because variability in temperatures and in ozone transport are both driven by the same atmospheric processes).
