There is a good argument to be made that AGW, if there is any, has arrived just in time to stave off a freezing disaster.
On balance, both theories were ill-advised attempts to portray short-term minor changes as large-scale major pattern shifts. The real drivers of large-scale change are much slower in their impact and if we get really lucky, our presence on the planet will overcome the next glacial episode which we can expect in about ten to thirty thousand years from now.
I think anyone will agree that this is the least of our worries on this particular planet at this point in history.
