The article is from Januay 2000, so they were going wherever almost four years ago now. It deals extensively with the freezing and killing effects of the glaciation, of course.
And both your statement above and what you posted evades completely my refutation above. There could have been no marine life - as we know there was (and as evolutionists themselves claim there was) if the oceans were covered with ice. So as I said, that article is ample proof of the depths of irrelevancy to which that journal has sunk while being guided by a raving evolutionist.
Yes, we all know that when a lake freezes over in the winter, all life in the lake dies. (sheesh!)
Read the thing before you announce you have refuted it! Much died, some lived. Life can exist under a lot of conditions.
