"The constant cycles of cooling and warming has occurred for millions of
years. Why is the fact that we are in a heightened solar flare cycle and
both the Earth and Mars are getting warmer not of interest to you? What
caused the glaciers from the last ice age, over 10,000 years ago to thaw?
What caused those glaciers to form in the first place? Something you global
warming adherents fail to comprehend is that the planet does not exist alone
and that the Sun is an integral part of our existence and has a dramatic
effect on our planet and our own existence."

Bert,
Does the ozone hole exhibit geologic cyclic behavior, also?
One of the things the Global Warming folks bring up is that the ozone hole
is getting bigger and that is, in part, attached to the claims of man-made
global warming.
