One of your best Lynn. But I have a couple of questions WRT warming. Q1: Why is it that the north poll was a shallow sea 65 million years ago at the end of the Jurassic era? (read, no ice cap) Q2: Is it warmer now than it has been in the past before modern man? (nope, not by a long shot) And here the kicker :-) Q3: Why are the ice caps on Mars getting smaller? SUVs? (Nope...) No disrespect, again one of your best, just think about the questions raised, and there are many more. But I limited it, brevity is the soul of wit ;-)
Robbie, I appreciate you taking the time to view this, and I appreciate your comments. In regard to warming - I graduated from KU in '75 with a major in physical geography and a minor in geology. Even then this subject was controversial. I was taught that global warming was happening, though, there were numerous reasons for the cause. I was also taught that some scientists believed that we're still in the last ice age, just that right now, we're living in an interstice of the ice age. There have been four major advances of the ice and four retreats. As for Q1, the north pole wasn't in its present position, and the atmosphere was radically different. There was little free oxygen to protect the earth from UV and other space related causes. Plus, there was much more vulcanism then, and the surface of the earth was hotter. Q2 was just answered. As for Q3, there are many more SUV's than you realize on the surface of Mars. Thanks for the thought provoking questions which really have no definitive answer. Thus, I avoided assigning blame for global warming; I merely point out that it's happening. I usually err on the side of caution, and if humans have anything to do with it, then we have the power to affect change.
