Does this mean we weigh up to 15% less than we used to when we step on the bathroom scales. If so let me know so I can pass the good news to my wife. (she's at Curves working out as I type this)

"Does this mean we weigh up to 15% less ...?"
The thing you're asking for - the decrease in gravitational constant - is on the legislative agenda for the 2nd GWB term. This alone ought to impress upon everyone the acute importance of the coming election. And remember: to make it happen the President will need the strongly supportive Republican Congress, or the stinky Rats would filibuster this important initiative.

Sorry. Our weight is caused by the earth's gravitation--i.e., by our mass and the earth's mass--not by the earth's magnetic field.

No, gravity causes weight, you don't even feel a magnetic field, unless you're hanging on to some iron, and even then you couldn't feel the earth's field. The compass in your car can "feel" the field though. Might require a new compass, or you could learn to read the one you have backwards.

The reduction in the strength of the field is presumably only a temporary condition. The field would dwindle to zero and then build up with the opposite polarity.

It's happened before.
