I subscribe to the natural cycle theory but being modded by our activities. I do not like 'constant state' theories, too much dependenat on something else to make me beleive that the planet is 'constant'.

We beleive that CO2 allows heat to be retained, but we really have no concrete evidence from observation and repeatable experimentation- this is where science gets its facts from. The bad part is we are talking about the thin skin of the planet where we live and I am certain I do not want to see an experiment go really wrong.
