It is also possible for cold climates to increase chemical weathering in some ways, by lowering sea level to expose more land to erosion (though I'd guess this can also increase oxydation of C in sediments) and by supplying more sediments via glacial erosion for chemical weathering (of course, those sediments must make it to warmer conditions to make the process effective — downhill and downstream, or perhaps via pulsed ice ages -LRB-?)-RRB-.
