Increased CO2 and warming will change weather patterns, including wind and rainfall, so it's possible to have localised cooling while still having a global temperature increase. The other hypothesis that I've heard is that increased CO2 could lead to more evaporation, which means more rain and snowfall, which gives you increased albedo and then cooling. If there's enough delay in that feedback then you could potentially trigger an ice age/mini ice age, but I haven't seen any modeling so it's hard to say how likely it would be.
