Hi DA; all I said was you two were talking about two different angles.
Anyway, re: "...something that may not happen for tens-of-thousands or millions of years."
I think it's pretty well established that we are already entering a pole reversal. They seem to switch kinda like glaciations too; y'know, sputtering a few times and then finally switching over, as if there is some "tipping point." Also interesting is that again, like glaciations, the sputters and switchs occur on the scale of several years to several decades according to geomagnetic data. Seems as if many cycles in nature are like that. Anyway, the 'sputtering' (multiple, shifting, and wandering poles) hasn't started yet, but if we've started a reversal, sputtering could begin on the order of anytime in the next few centuries.
Also, sorry, but I'm new and it's not clear if you meant me or dehammer re: "...the same person who is so convinced global warming is just a natural variation...."
