Wikipedia's global warming definition is the follwing: Global warming refers to the rising average temperature of Earth's atmosphere and oceans and its related effects.

There are many that will argue that this is not a man made problem or even doubt that there is a such thing at global warming. Folks get with it! If you read scientific paper which are not funded by large corportations ALL of them say that the temperature of our planet is rising. Not only are they rising but they are rising very quickly. These are the global warming facts!
Not only is it the higher temperature, it's the speed at which it is risking that is the scary part. If you look at the ice cores and fossil records we can tell that the Earth has been hotter before but never has it warmed this quickly before. This very quick rise in temperature directly coincides with man discovery of oil! There is simply no doubting that global warming is real and caused by us!
What causes of global warming you ask? The very short answer is, humans. To be a little more detailed though it the increased consentration of greenhouse gases (carbon dioxide, methane, etc) in our atmosphere. They are called greenhouse gases because they allow the rays and heat from the sun to enter Earth's atmosphere but do not allow them to escape. The effect of these global warming causes over time is to increase the temperature of Earth.
So if you are looking for the casues of global warming then you are really looking for what is causing more green house gases to be released into the atmosphere. These are human activities that release carbon dioxide and methane. Essentially this is burning things that contain carbon. Coal, wood, and oil are the big ones. Methane pound for pound has a much larger greenhouse effect but you always hear about carbon dioxide because it is so much more abundant then methane. For a while the folks who are against doing anything about global warming were arguing that cow farts were much worse for Earth then buring oil. It made for great news story lead-ins. Like all the arguments against global warming though the facts are warped to make their point. Yes a pound of methane in the atmosphere will reflect more heat back down to Earth then a pound of carbon dioxide. That is true. But there is just so vastly more carbon dioxide being released then methane that the arguement just doesn't make sense. It's the same as saying that a big dog bite is worse for you then a kitten scratch, which is obviously true. But they fail to mention it's one dog and one bite, but it's 10 billion kitten scratches all at once. The dog bite will hurt, but the kittens are going to kill you.
So if for some reason you are still on the fence about global warming then read up on it. Just make sure you know who is writing the global warming articles you read. Many doubter articles are written but groups that sound legit but are really just fronts for big business and folks that have a vested financial interest in not combating global warming and the end of our planet!
