No proof at all and no fraud, just someone twisting information and discussion to fit their own agenda. And ***Calliso ***has provided links to reports that give a good overview (some with a lot of detail) that address the studies referred to and provide a window into what the scientific process is all about.
You need to understand that there is no “global warming” conspiracy. If you were to read the reports going back 50 years or so, you would see how the ideas developed through observation, experiment and study by scientists in various fields, little by little, study by study. You should also realize that any information presented in a scientific journal gets vetted, and that other researchers review the data, replicate the studies, compare them with findings by other scientists, interpret the results. And scientists question all the time, since that is the nature of their profession. How do these results compare to what others have found? How does the data from tree studies compare with data from sediment cores, or the ice caps, etc? What other explanations could there be for the results?
And as more data is gathered and new and better techniques for extracting and analyzing this data are developed, we learn more. I recall that in the late fifties, some scientists were indicating that a new mini “ice age” could start within a hundred years, as the earth’s climate cooled. This idea came from some of the data being collected during the IGY, which was really the beginning of major efforts to understand the earth. But so much more has been learned since then, and of course few, if any, would say that we are heading in that direction now.
This continuous process produces a lot of information, some of which may be in agreement with prior studies, some of it not. But you cannot suggest that global warming is occurring or not occurring just by one study or one person’s interpretation of one set of data.
The question to be answered is not whether “global warming” or climate change is true. There is absolutely no doubt that climate change has occurred over the eons, and will continue to occur. It is a naturral ongoing process. The questions to consider are: What is occurring now? Which way is it headed? Is it accelerating? Is human activity contributing to the speed, direction or severity of climate change? What will happen if current trends continue? What, if anything, can we or should we do about it?
When you look at the information that we have on earth’s climate going back thousands and tens of thousands of years, one thing that stands out is the realization that we are in a benign part of the cycle, and that the overall climate conditions have probably been near the optimum in recent millennia. Perhaps this is one reason why civilization has been able to progress so much in the past few thousand years.
And like any other cycle it will continue to move, and conditions will change, and those changes will likely not be positive ones, overall. That may not mean much to my generation, but it may be disastrous to the generations of the 21st century and beyond.
