Brake squeal is caused when the brake pads actually vibrate. This is caused by a lot of things - how thick the pads are, the material, even how the edges are worn. There is a spring on the side that helps some, and the pads are held in with springs.
There is squeal, and then there's squeal due to worn pads. If the pads wear down enough, you get metal on metal - the pad material is gone. This doesn't produce squeal as much as the grating sound of metal on metal. You should never run the pads that low, because the pads (actually, just the metal pad backing) is chewing up the rotors.
One solution is to replace the pads. There's obviously something about the combination of thickness and how they've worn that's causing them to squeal right now. The other is to wait and see if the pads wear through this 'phase'.
There are anti- squeal compounds. Since the squeal is actually the pad vibrating, if you can damp out the vibration, you get no squeal. The compounds consist of gummy material that goes on the BACK of the pad. This damps out the vibration. Some brake pads come with the stuff, usually a tube of goo you spread on the back. You can also buy it at most autoparts stores. They also sell a spray-on version. In either case, you need to remove the brake pads and put the stuff on the back. You also want to make sure you put the pads back on the same wheels! You can't easily screw up the inner and outer pads (different backs), but you can accidently screw up left to right if you're not careful.
For that effort, I'd just slap on a new set of brakes, unless the present set have A LOT of pad left. And for a little insurance, stick some anti-squeal compound on the new pads.
Good luck!
