Global Warming, er Climate Change is a National Security Threat


Quote:One of the positive feedback hypotheses that I have heard of is that the water under the ice sheet at the North Pole is dark, and as the ice melts, dark water is exposed, which absorbs more heat therefore melting more ice. And so on.


I don't happen to believe we are doomed, because I believe in our ingenuity and adaptability. But of course it will be a lot easier to adapt if we are able to recognize a looming problem.


But let me ask you a couple of questions.


1) Do you believe that a positive feedback in the environment is possible?


2) Do you believe that it is possible that mankind can damage the environment to an unacceptable degree?
 

0) The effect is negligible. The ice is only slightly more reflective than water at that high angle. September is the month of lowest ice coverage, so half the time the north pole will receive no sunlight at all.


 

1) Not with temperature. Not with climate. Biologically I can see the possibility.


 

2) Sure. Nuclear weapons can do that. CO2 can't. The Earth has had higher CO2 levels than the predicted 2100 level for most of it's history.
