Certainly the climate has changed in the past, both warmer and cooler. There may be an Anthropogenic factor, but the kinds of rhetoric that have accompanied the debate have not served to convince me that the debate is based on scientific evidence. I remember when models predicted a runaway greenhouse effect similar to that on Venus. Those predictions have now tempered somewhat (an understatement) and are likely to be further changed. In any event, both a warmer and cooler climate worldwide is certain to be in the future, with or without the influence of man.
It really is all about money! So called scientists who have received grants due to Global Warming Theory and people like Al Gore who have made a lot of money from this myth have clearly falsified and misrepresented the data. Those who still blindly follow these debunked theories are not scientists, they're cultists.
Its all about money. There is climate change and its changing with or without us. We had better learn to adapt.
