I read a letter to the editor in our local paper that put it in perspective for me. The writer said that the Earth's age is measured in the billions of years; modern man's existence and observation of the climate in relative terms amounts to trying to determine what is the normal climate by observing and measuring it for 15 seconds.
Personally, if man has anything at all to do with the climate, I would hope we do warm things up. I hate cold.
No one has yet explained how CO2 content in our atmosphere affects warming on other planets. I don't know how the temperature on other planets is determined and really don't care, but it is said that at least some of the other planets have warmed up too. If that is true, wouldn't it be logical that since the sun is the prime source of heat in our solar system, just maybe sun activity is the prime mover for global warming. Perhaps CO2 content is a modifier, but CO2 is a relatively small percentage of the atmosphere's makeup and from ice core samples the climate has been both warmer and colder when CO2 content was much higher than now.
If those who believe global warming is a bad thing and that it is being caused by man's activities, would quit doing those things, the rest of us would be just fine.
