There are a few different things to take a look at, since some people believe it is real, some don't.  Here is a site that suggests we need more CO2:

Here is another claiming the opposite of the main stream view:

This wikipedia link has a lot of interesting information but more importantly a good list of links at the bottom to use:

Global warming is impacting our planet in many ways.  It is causing the ice caps to melt, our sea levels to rise and heat up, and it is increasingthe severity of storms. Some of the causes for global warming are the cutting down of trees, the burning of fossil fuels, and the development of land.  Below is a link to the EPA's website.  It may be helpful.

Whats happening is that chemicals are being produced by us humans, which are harmful to the ozone layer that surrounds and protects our earth from the UV rays of the sun. Without the ozone layer our earth wouldn't be able to exist as we know it. One majorly harmful substance is chloroflurocarbon, which when it reaches the ozone, is broken down by the intensity of the UV rays, releasing chlorine, one molecule of which can break down 100,000 ozone atoms. Chemicals like chloroflurocarbons produce 84% of the chlorine which depletes our ozone faster than it can form.
At the same time, green house gases such as carbon dioxide and methane are trapping the additional heat entering through the depleted ozone, in the earths atmosphere. This additional heat results in a hotter planet, resulting in melting ice caps. The problem with the ice caps is that they consist of fresh water which has a lesser density of 1.00 to salt water's 1.025. This means the fresh water sits on top of the salt water, and this disturbs the thermohaline circulation, or Great Ocean Converyor Belt. The ocean conveyor is responsible for moderating the heat across the planet, therefore if this is disturbed or shut down, it could lead to cooling in the Northern hemisphere, which in turn would result in an ice age.

Global warming is itself controversial. Some scientists will say that it is something that is going to happen no matter what humans do on Earth. Others say it is happening because of us and we need to change many things to stop global warming. I agree that we need to take steps in order to protect the environment. This can be done in numerous ways such as driving efficient cars, recycling, cutting back on energy use, etc.

With the debate as to whether it is inevitable or it is us, I feel that it's fair to say that we are responsible. In particular, with the ozone layer and the greenhouse gases, yes they have always been and will always be produced, yet because of us the amount of gases produced has increased immensely because of us. With chlorofluorocarbons, they are predominantly produced by us, and I agree that we can reduce the chemicals toxic to the environment with efficient cars, recycling and reduced energy use, because a lot of the things we use that are detremental to the envionment, we could find better options for. However, I've just done some extra reading and it turns out that use of CFC's has been majorly reduced and is monitored, so that's a good thing :)

Global warming itself is not necessarily a controversy. However, people are arguing about what causes it. That is the controversial part. Some say it is caused by humans, others say it is a natural phenomenon and we did not cause it with pollution.
