The Earth, and all things that exist for that matter, can be described in terms of cycles. There is validity to the concept that ice ages and heating cycles are occurring every so often, and not that far apart when held relative to geological time scales.
The Day After Tomorrow, while somewhat silly, at the VERY least brought these issues to the attention of an audience who might not otherwise pay much attention. It is (loosely) based on fact, and I enjoyed it myself. Had wonderful graphics... like the sequence where the tidal wave came in over Manhattan... that was righteous.
The bigger issue raised when Global warming is discussed is our impact on it. Clearly, millions and millions and millions of cars and factories (and...) burning fossil fuel are having an impact, and the shifts are more than just nature cycling.
Anyway, welcome to Hypo ipruul. It's a bit like walking through the halls of multiple great universities and discussing ideas with those around you... but all from your computer. Enjoy!
Cheers.
