Global warming - or cooling, due to solar flux and independent of internal mechanisms (like us) has been the mainstream knowledge for a long, long time. Interesting that you chose this one, Cecil. Mention Al Gore's name, and you can bet that the more neoconservative among us will start the ridicule bandwagon going. They say it is a political thing. It is for them. Heat retention by the group of gases collectively know as "greenhouse gases" is a fact. Proven time and again in experiments that a high school kid can do. There is a direct correlation between human activities that release CO2 into the atmosphere, and the percentage of CO2 in the atmosphere. This increase should have an effect on the heat retained by the atmosphere. Doesn't matter what the CO2 source was. Global warming is just as much a fact as evolution, and opposed by many of the same folks as that one. Now it is time for those who would debunk it to come up with solid scientific reasons why the effect is not happening, not political ones. Here are some possibilities: Humans really aren't putting CO2 in the atmosphere. That CO2 is different. The earth wants to maintain a constant temperature, so it somehow ignores that CO2. Temperature measurements are actually wrong. That kind of stuff. Give how's and whys. Not political verbiage. Show me a guru who thinks he knows everything and I will show you a very ignorant person. - 73 de Mike N3LI - |
