If you're standing in the middle of the congested Los Angeles region, it would be easy to buy into man made global warming. If you look at a California map, it isn't.
When you look at a broader map of the Western United States, it is startling how tiny the over all man-made foot print there really is.
We credit ourselves with too much power over nature. I consider it to be humorous, the thought that we are warming the planet. The cyclical human, plant life, plankton, and other factors that play into this, dwarf man's ability to damage the earth's atmosphere.
Yes, we are making contributions. No we are not endangering our futures by any stretch of the imagination.
Do temperatures fluctuate? Of course they do. Every year is a little different. One year it's warmer drying. The next year it's wetter cooler.
One of my favorite pastimes is to watch the weather people talk about nothing but the need for rain for six months on end here in Los Angeles. Within two hours of it starting to rain, they are talking about how soon it will end.
There's far more to the human nature aspects of this than mother nature. We obsess constantly.
