Thoughts on Global Warming- Not new but here it is anyway

A reader commented on the reliability of one of our previous posts.

Perhaps Monckton is capable of distortion, but certainly no more distorting than Gore and others. I guess we can play the "gotcha" game ad nauseum, what with the news that NASA was off on it's temps, problems with computer models,and the "snow job" that appears to be the case with the Kilimanjaro data. But my point is, and always has been, more of a cry against the shrillness and false certitude that global warming folks seem to have about the issue. It smacks of an agenda beyond science that I distrust especially since in my lifetime the pendulem of media alarmism has swung full scale from ice age predictions to the current global warming hysteria. Where is the open discussion of the matter that good science would seem to demand? We simply do not know if we have caused the warming or if it is part of the natural cyles, or indeed, whether we are warming at all. After all what is the earth's "normal" temperature? The whole discussion seems to have evolved into hubris masked as certainty.
