Okay, with this section of my blog, I will just immediately hit it with a hammer right away with this hotly-debated subject for my first post. I guess I will start out with the science of the whole matter (it is the boring part, but it is required to understand some other aspects of the post).
There is a common misconception about the definition of the term "Global Warming." Many people believes that it is the process of the Earth heating because of human actions and emissions. Not so. Global Warming is simply a term to describe the whole Earth heating, whether it be caused naturally, astronomically, or by human actions. Global Cooling is the same idea, only relating to the Earth getting colder. Many people have drilled the wrong definitions into the heads of others so as to try to achieve their own ends.
The theory of Human-Caused Global Warming is simple. Carbon Dioxide and other emissions block the warmth of the sun from escaping the Earth after it bounces off of the surface. Sounds plausible, right? Unfortunately it is not. Venus is often used to symbolize this type of Global Warming. The truth is that Carbon Dioxide DOES block sunlight. But here's the catch. Venus has had a couple billion years to get the gas into its atmosphere. It has so much of it, we would have to burn all of the oil the world has ever had several thousand times in order to create that kind of Global Warming. Good news for us. The bad news is that Global Warmings can be very, very dangerous.
Back a hundred million years ago there was a time called the Permian. It was a time of great deserts and immense heat. It was a time of Global Warming. Scientists debate today over the cause. Some say meteor, others say volcano interference, and many other things. Some even consider that we have another sun that comes every 40 million years to cause mass extinction. Anyways, the Earth heated 10 Degrees. Only ten. That was enough to kill 90% of life on Earth. Why? Because there are rich deposits of heat-sensitive minerals in the ocean. When the Earth heated up 10 degrees, those minerals melted, creating a reaction that skyrocketed the temperature immensely.
Global Warming is very much real, and has happened before. However, our Earth's temperature is always raising and lowering by two or three degrees as result of several natural processes. It is much easier to trigger an Ice Age than Global Warming.
On the topic of Global Cooling, I think that it is another dangerous thing. Effect-wise, it would be most disastrous to us early on. We would lose crops, forest, and many other things that are almost necessary for our survival. Then, after all of that is gone, the effects would not be as bad. Much of life on Earth would be annihilated, but not all would be lost. We could endure that. In the long run, Global Cooling would not be as disastrous.
There are some people that would like you to feel guilty about "poisoning" the planet, and profit from that. Some are benign enough, but there are a couple who do what they do for gain and to get revenge on others, including the government. I will address some of them in my next post.
Those are some very good facts you pointed out.
