Atmospheric physicist and meteorologist Bill Pekney has a fascinating perspective on climate change. I've been thinking about this for years and years and just now have gotten to it in the last five years to write it. And the book is intended to be not a textbook, but an easy to read, big picture summary of evidence based information about how the climate works from a big picture standpoint. One of the main themes is that the real control knobs on our climate are the sun, water, 71 percent of the earth's surface is covered by water and planetary motion. And then I talk about pollution and I'm a strong advocate of clean air and water. But there is a way too much focus on carbon dioxide as opposed to the real pollutants. Carbon dioxide is not a pollutant and get into the greenhouse effect in the book. And why it is that it's not carbon dioxide, that we should be emptying our wallets on its pollution, because what's warming our planet is normal and beneficial. And it's not carbon dioxide that's warming our planet. The greenhouse gas that prevents our planet from cooling too much is water vapor in the air. Carbon dioxide is a drop in the bucket as far as greenhouse gasses go. Keeping us at a not too warm, but habitable global temperature. If it weren't for the water moisture in our air, our planet would be perpetually frozen. Never heard that before.
