Trying to Put Orthodoxy Into Perspective

I write this because I find it hard to believe that man is as responsible for GLOBAL WARMING as the usual suspects tell us. Forgive me for being so stupid, but I got really suspicious when they started to refer to it as CLIMATE CHANGE. Odd, if THE SCIENCE IS SETTLED, why go to the ambiguous when you started with a definite?

Truth be told, my suspicion of the orthodoxy began when a GLOBAL WARMING religionist explained to me that the current changes in the sun cycle were not a factor. Odd again, because the lynchpin of his theory, be it WARMING, or CHANGE, was the Greenhouse Effect, a theory that depended on the sun's indirect effect on the planet. Derided as irrelevant, that climate change on Mars is mimicking ours without the benefit of our atmosphere or a human race, my suspicion meter went off the scale.

Let's not get into the science. I probably wouldn't understand it because I can't get past the knowledge that water vapour is the largest greenhouse gas at 90+ per cent. That makes carbon dioxide a small part of the whole. Our concentration has been on mankind's contribution to carbon dioxide, a small part of that whole. How are we going to save the world if we are concentrating on our small part of a small part of the problem? Never mind going after water vapour, how could we ever compete with the oceans?
That brings me to an exercise that helped me put some of this into perspective.

The exercise is to calculate how large an area the world's population would occupy if everyone assembled in one place.

Assume 7 billion population. Each person is given a .5 meter X .5 meter square to stand on. That's 1,750,000,000 sq meters or 1750 sq kilometers. A 41.83 km square. That's probably close to the size of Metropolitan Toronto.

To illustrate this, take out a standard 8.5 X 11 in. (215.8mm X 279.4mm) sheet of paper. The world's area is approximately 510,072,000 sq km., land and water, so a sheet of paper this size would represent 19,853 kilometers X 25,692 kilometers, or so. Use a normal ball point pen to mark a dot on the sheet the size of the dot on a letter i. Darken the dot just a little as you would for emphasis. If that dot is just under 1/2 mm in diameter, you have successfully represented the biggest meeting on the planet.
