Wow, what a thread.
Personally, I'm all for conserving resources - it's called being responsible. However, I take issue with this fanaticism with Global Warming and, by definition, that's exactly what it is.
I still want someone to explain the research the ancient Egyptians did on global warming. Their "scientists" were concerned that the sun was getting hotter as a result of Ra's anger. The summers were getting hotter every year, and it was adversely affecting the crops. They researched the temperatures (using water thermometers which are just as accurate today as they were then) and water tables. After several hundred years they decided that the sun got hotter and cooled off in cycles and that is what was causing the global warming and cooling trends. They charted about a dozen cycles, all with varying degrees of temperature change, longevity, and speed. Also, the peak of the highest recorded mean temperatures and the lowest valley of all of the recorded cycles occurred in one cycle, which went from cold to hottest ever to coldest ever in less than 100 years. That's pretty darn quick, and the temperature variances were larger than any we've seen in the past 100 years.
An ecology professor of mine showed me some books which detailed these findings. The books had nothing to do with global warming, it was a research of ancient Egyptian "scientific methods". There was a lot of stuff in it on medicines, poisons, and magical spells, but this was the section on their study of weather. Of course, they placed more stock in their fortune tellers weather forecasts than their scientists'.
Anyway, the internet has become so bloated with information on global warming that you can't really find this info - at least I can't. And, to be honest, I don't care enough about it to spend the time searching. However, there are at least a half dozen history books that detail this study, all mentioning it matter-of-fact-ly and all written prior to any global warming "crisis" and debate.
I wish I could get the names of those books he had, but unfortunately the opportunity to ask has passed.
Anyway, I'm sure if you look hard enough, you can find the details of what I'm talking about. The problem is you have to look in the History section, not the Science section.
My question is this: if it's not primarily a part of a natural cycle, and we are the major cause of this warming cycle, then why were there similar instances recorded in history?
Some will say that it is cyclical, but we are making it worse, and it's happening worse or faster than it has before.
The problem is that the temperatures and water tables recorded show larger temperature changes than we've recorded and, in that one instance, a greater speed. That is unless, of course, the physical properties of water has changed in the last few thousand years.
My professor showed me this stuff when this global warming fad was starting, and these books were all 30 or 40 years old, at least. There was no political reason for fabrication when they were written, and I can't think of any the Ancient Egyptians might have had.
The simple truth of the matter is this:
1. The mean temperature of the Earth has been rising over recent years
2. Many scientists believe that man is a/the primary cause (many do not)
3. There is absolutely no way to prove one way or the other
4. Most of the evidence on both sides is not scientific*
5. This debate is being fueled by politics
* see the text-book definition of scientific study - for evidence to be scientific, it must be studied scientifically which, by definition, requires the event to be observed from beginning to end and then be replicated with controlled factors on an equivalent scale. Somebody please tell me how you can do any one of those things in a study of global warming without the benefit of time travel!
