Do humans contribute to global warming? - Bill Cagle's opinion

I'm 100% sure that humans do not CAUSE global warming, but I'm also positive that our influence is very significant in that matter.

There are five gases that contribute to the greenhouse effect:

water vapor - it increases as the Earth's atmosphere warms. Although the warmer the atmosphere is the more clouds it creates, and clouds do cool the atmosphere down.
carbon dioxide - it's released to Earth's atmosphere mostly through natural processes such as respiration and volcano eruptions. The humanity increased atmospheric carbon dioxide concentration by a third since Industrial Revolution began.
methane - gas produced through natural processes and human activities (e.g. decomposition of wastes, agriculture, manure management). Much more effective than carbon dioxide, but also less abundant in the atmosphere.
nitrous oxide - is a gas produced mostly by soil cultivation (!)
chlorofluorocarbons - greenhouse gases that are now highly regulated for their ability to destroy the ozone layer. They are entirely of industrial origin.

Climate change is entirely natural process. It occurs cyclically since the formation of our planet, as do the ice ages, and it was responsible for the rise and fall of many ancient civilizations (e.g. Mayan civilization). We must not forget that Earth’s climate has been stable for the past 12,000 years. It was inevitable - it could occur now or in the nearest future.

Although the rapid climate change is very dangerous (it warms the oceans and melts glaciers), we must not forget that without the greenhouse effect there would not be any life on Earth. Planet Mars has a very thin atmosphere, and although there is a lot of carbon dioxide in it, it lacks water vapor and methane. Mars' surface is mostly a frozen wasteland without any signs of life.

Yes, and co2 is only 0.0397% of our atmosphere, such a small factor can't contribute to global warming. Earth has gone through cooling and warming periods. In the midevil age it was warmer than it is now, with no human produced co2. This is all just an excuse for ecologists to stop oil production domestically. We only mine 50% of our own oil, and go to other countries and kill other people and our own troops for oil. It's disgusting. Ecologists want to trade trees for lives, which is wrong.

No one is denying that global warming (and cooling) is taking place. The +problem+ is that there bad decisions being made with information from the hysteria which is being created by the alarmists.
International Socialists like Gore are creating a false hysteria in order to scare the masses into giving up freedom and to submit to more government control, more “international” government control. Wake up, America! He who controls energy controls the world.
As Margaret Thatcher put it: global warming is proving to be “a marvelous excuse for international socialism.”
Global warming is indeed real and has been documented with ice cores dating back tens of thousands of years.
What is NOT real is the quackery that humans caused (or can even affect) global warming.
The scare tactics being perpetrated upon us are only a money/power grab scheme by bottom-feeder politicians accompanied by their so-easily-led sheeple who take their prattle, even their movies, as hard science..
To find that my statement above is true, follow the money. See just who it is who will profit from the carbon offset, carbon tax, & etc.

Here is truth about global warming:

Global warming is one-half of the climatic cycle of warming and cooling.
The earth's mean temperature cycles around the freezing point of water.
This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.
Our planet is currently emerging from a 'mini ice age', so is becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).
As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).
When this cycle slows/stops, the planet will cool again and begin to enter another ice age.

It's been happening for millions of years.

The worrisome and brutal predictions of drastic climate effects are based on computer models, NOT CLIMATE HISTORY.
As you probably know, computer models are not the most reliable of sources, especially when used to 'predict' chaotic systems such as weather.
Global warming (AKA "climate change")
Humans did not cause it
Humans cannot stop it
