I remain a wee bit skeptical about global warming.
From what I have read, there has been no noticeable change in land-base thermometric readings except in large cities where temperatures have risen slightly. Neither of the other measured medium (high air/atmosphere) show temperature change. With the popular hypothesis that there has been an ongoing natural warming and cooling of the earth, I question the angry trumpets about man’s dominant role in global warming. I tend to view much of the clamor as political. After all, there is big money (and political currency) in the “business” of sounding the claxons on global warming.
Hypothesis in science (though not in politics) requires testing and investigation. So far, “advocates” of global warming observe that some glaciers have thawed and conclude that there is global warming (did you know that the Antarctic ice shelf is growing?). Bad weather is blamed on “global warming.” We have descended into science by consensus or worse — speculation. The tragedy is that anyone — even scientists — who want to test, disagree, question or discuss is demonized, criticized and slandered.
I continue to believe that this issue should be examined and discussed by people smarter than me. Dispassionately. Productively. Conclusions should be reached by experts – not politicians or journalists. And certainly not by those with agendas. We ought try to calculate what percentage of global warming (if it is determined to exist) is attributable to man and what percentage is attributable to natural causation. However, we should continue to be ever-vigilant about conserving energy, water, soil, natural resources and our environment. We should recycle. And we should declare global war on pollution.
