Besides lower temperatures, are you awarew of any other effects this might have?

Also, how does this factor into AGW?

Not much … it may get interesting tho as we find out.

High latitude magnetic fields have been observed with solar telescopes on the ground. However, actual process of the polar field reversal is poorly understood because of the difficulty of the observations on the extreme limb combined with atmospheric seeing effect. The solar optical telescope aboard the Hinode satellite allows us for the first time to perform extremely high-quality observations of the deep polar region of the Sun (Figure A).

Because the Sun rotates (once every 27 days) solar magnetic fields corkscrew outwards in the shape of an Archimedian spiral. Far above the poles the magnetic fields twist around like a child’s Slinky toy.

Because of all the twists and turns, “the impact of the field reversal on the heliosphere is complicated,” says Hathaway. Sunspots are sources of intense magnetic knots that spiral outwards even as the dipole field vanishes. The heliosphere doesn’t simply wink out of existence when the poles flip — there are plenty of complex magnetic structures to fill the void.
Or so the theory goes…. Researchers have never seen the magnetic flip happen from the best possible point of view — that is, from the top down.

“Right now, there’s an imbalance between the north and the south poles,” says Jonathan Cirtain, a space scientist at NASA’s Marshall Space Flight Center in Huntsville, Ala., who is also NASA’s project scientist for a Japanese solar mission called Hinode. “The north is already in transition, well ahead of the south pole, and we don’t understand why.”

It may dampen the it for a while, but not change the effect. We could see nothing done and then face a double whammy when things come back, although when I say we, I don’t mean me.
