ferrett (16:35), Deadeye (16:18), 2_Point (16:09). It seems that
there are the three of you plus me, making at least four who doubt that global warming is man-caused. So I agree with Deadeye when he says lets keep things in perspective and I agree with Deadeye’s postscript message about the importance of trying to bring defensible information to lay persons about the complex physical aspects of temperature changes in the solar system, the atmosphere, on land masses, and in the oceans.
It was in the context of Deadeye’s postscript message that I posted those two links today about measurable indicators of long-term warming trends. I posted them because there are many persons who still do not believe that there is detectible climatic warming, often because by some meteorological event they happened to get a snowfall in June when they should have already been harvesting some vegetables or fruit.
My posting was directed to the people with blinkers who deny that ground ice is melting away in tundra soils that have been perennially frozen ground since the surface glaciers melted back a few thousand years ago. The same blinkered souls seem also unable to recognize the magnitude of climatic warming required to melt out the multi-year ice that has covered the surface of the Arctic Ocean for so long.
It isnt very long ago that the current political leader of Canada and the current political leader of the United States would not acknowledge that there is climatic warming, so I think there are many others who still feel that way today. Therefore I feel justified in distributing what I think is defensible evidence of a trend to global warming. That is a physical process that is a subject in its own right. The question of whether some of that warming is attributable to humankind’s accelerating release of gases that have a greenhouse effect in the atmosphere is a totally different subject. Sensible people should be able to discuss these two separate subjects, without the second subject (possible human causes) hijacking sensible discussion of the first subject (the evidence for global warming).
Cheers, all. Equiz.
