These articles cite increasing evidence that man made emissions from the burning of fossil fuels may play less a part in global warming than originally thought. Indeed, the actions of humans may play such a minor role as to be neglible at best. It seems that the sun periodically goes through cycles where it is more active, and since the weather on earth is influenced directly by the sun, these periods of increased solar activity result in dynamic weather here on earth. There is evidence that the earth has gone through "global warming" such as we currently seem to be having now a number of times in the past, when there obviously was no possiblity that man was the culprit, and we eventually emerged from those periods in the natural course of events. In fact, one of the most compelling pieces of evidence for "global warming" being triggered by our sun and not by man made activity is the fact that several of the planets in our solar system have also indicated evidence of dramatic warming . Obviously man made emissions have not caused any "global warming" on Mars.
This latest research highlights the folly of the "we must do something, anything NOW" approach to global warming before we have a more complete understanding of the problem. Any of the current popular "solutions" to global warming carry the possibility of significant disruptions to our society, and should not be implemented without serious consideration of the benefits vs the enormous cost to our society. Additionally, the primary way suggested to deal with global warming currently is to drastically cut fossil fuel emissions in the industrialized countries ( a scientific smoke screen for the "soak the rich" school of thought) without addressing the fact that the vast majority of these emissions are currently produced by the "Second" and "Third World" countries. Without fully investigating the actual cause of the warming prior to advocating action, we run the risk of making the cure worse than the disease.
