out of respect for Mr. Wahlberg it's best if you don't post this even though you think it might be true.
If he says this and you have sauce, then please do post it.
Did John every study Geology and does he know about the cycles of glaciers, all of which happened thousands of years ago?
is he not aware that techtonic events are the real reason for climate change, when continents shift their orientation?
does he understand that the Georges Bank was above water and that western New England was much lower?
the plate of the Earth shifted, probabaly rather suddenly. It wasn't because of warming but because of earthquakes and tectonic forces, that might be due to solar activity far more than the effects of man.
Does he not know this?
