Exactly TIA. A+ on that one.

If natural Astronomical cycles caused them, why isn't that the reason for the current cycle?

The cycles are almost evenly spaced so aren't we due for one anyway? Maybe mankind has finally been able to replace a natural cycle with one of it's own making.

Now tell me why the peaks are all different?

After you have politely cleared up all my undecidedness with out resorting to personal attacks, please answer my overarching question which in my opinion makes the current debate, which the real smart people claim is over because they have lost their subjectivity, irrelevant and short sighted.

If and after this greenhouse gas "crisis" is solved, How are we going to prevent the build up of heat in the atmosphere that is produced by even 100% clean and efficient energy sources of the future?
