Volcanoes and global cooling

The recent volcanic eruptions of Mt Redoubt (Alaska) could provide some empirical evidence a few months down the road of the potential after-effect of global cooling. 

While the physical and chemical processes are indeed complex,  the spewed effluent and ash will most likely bring some atmospheric impact over regions expontentially larger than the point source.

    Time will tell. Redoubt is not a minor volcanic event, plus transport of the effluent once it hits the stratosphere is more of a “smearing” effect that can eventually be tracked over very, very large areas. Jim Duncan

    Actually I am not sure the Redoubt Eruption so far has enough energy to cause Temperature drops. Also to affect GLOBAL temps the volcano has to be either really huge or in the middle latitudes. It may only produce a local effect.

    So, would it not be out of the question to think that a cooler Fall and Winter could prevail because of this? Also, could it be that all of the hype about global warming is just that and this is the way mother nature corrects herself by popping off a few valcanoes to keep things in check? Maybe we are giving ourselves too much credit to think that we actually affect the temperature of the earth? Just food for thought. Obviously forces bigger than us at work out there.
