Thanks for the book reference, will get it. The description of proxy data is very helpful. It certainly makes sense, and even I can understand this, that human presence on the planet contributes something to the environment, good or bad. Well over my head, but a possible question is so, okay, we are bad for the environment, so what? If the natural course of things is for that to be, then???????????????? In other words, we take a leap from the hard and fast "science" and move into the "whys?". That, I suppose, becomes more a philosophical discussion. On the proxy data, if I were to create a line representing the length of time the earth has been around, (or more relevant, the length of time the earth's environment is similar to today's), what percentage of that time would be covered by the proxy data? All of that time, only a fraction of that time? My point is that proxy data seems to be very important to the analysis and I sense that it is a very powerful tool used for the development of "models", then the degree of confidence in the data must be high. If my low level understanding is at all close, then is there a generally accepted level of confidence in the proxy data and how is that confidence determined? But more important, no one has answered my fish question, what next folks, what next????
