Now this is interesting, not just for the reams of data discussed showing that a magnetic reversal could be a really bad thing for us (and maybe in progress right now) but it is a disagreement at an academic level, where a data driven rebuttal is refused to be allowed, and for what reason? That is the whole point of all these groups and societies, to debate and examine all the data to come to the best, most likely conclusion. To reject or filter rebuttals is the exact opposite of why they exist. The fact they had to go to You Tube to put forth their position is pretty interesting.
