If there is such a thing as Global Warming, it can't be judged by one summer's temperatures being a little above normal.
I think there has been a warming trend over the past 100 years. Correct my math but I believe it to be something like a 1 degree rise in AVERAGE temperature. I've seen glaciers shrink and supposedly there are some islands in the Pacific which appear to be sinking. I have little else for scientific proof and don't possess a highly scientific mind. I've gotten to a point in life where stuff simply has to make sense. I tend to lean on logic (Spock) for that reason.
The earth began as a fireball, then cooled and went through an ice age. Somewhere in there it obtained an atmosphere which regulated the amount of sunlight and controlled the temperature. Oceans formed which produced oxygen. Earth made itself what it is, not man.
So is man responsible for global warming? Seems the earth controls much of it by itself. Has man contributed to global warming? It would be illogical for me to say no. However, we are talking industrial revolution, invention of automobiles, jets, chloroflourocarbons, and numerous other damaging products that harm the atmosphere and yet we are only up 1 degree. Wow, we are such terrible human beings.
The "green" people lose me with cow flatulence and other stupid contributors. Also, when the heads of state have their global warming conferences, can we ask them not to fly in jets? Anyone else see the irony here?
Just my personal thoughts and they may not be entirely accurate. Just the way I see it.
