My personal problem with the theory that this flux is going to cause global cooling is that, at least according to the actual temperature measurements, global cooling has preceeded the flux by a couple of years.
If the data is an indicator, something else is affecting the climate and that something has already been in effect for some time.
But of course, this messes up all the other theories on global warming I've heard of as well. I guess it never pays to muddy up a perfectly good theory by comparing it with data, does it?
