It's not! There is a natural greenhouse effect, which keeps the earth warm enough for life, but this is not what we mean by global warming.
As long as greenhouse gas concentrations remain at their natural, long term levels, uninfluenced by human activity, the warming of the earth is natural and has in fact helped maintain the world's temperature at a comfortable level suitable for human existence. The increase in global temperatures above this level is accepted by most climate research scientists as principally the result of human activity.
Greenhouse gases are gases that build up in the Earth's atmosphere and absorb infrared radiation. This causes a warming effect in the lower atmosphere and on the surface of the planet. The main naturally occurring greenhouse gases are: water vapour (H2O), carbon dioxide (CO2), methane (CH4) and ozone (O3). Water vapour does not refer to clouds that are lower in the atmosphere, as clouds are liquid water and reflect solar radiation, which would have a cooling effect.
They don't help with global warming naturally but the large buildup of greenhouse gases does assist with global warming.
Global warming is not seasonal, or annual. It is gradually increasing all the time.
Carbon dioxide has been charged and convicted of causing global warming.
If global cooling means the gradual cooling into an Ice Age, then that has happened in the past and it has taken thousands of years to happen. The present global warming has all happened far faster, in less than 200 years, and is threatening all life on the planet if we can't stop it. Global warming is by far the more dangerous situation.
Not quite, though they are very closely connected. Global warming is the warming of the earth. This is causing climate change, which is the many different changes in climate that are beginning to happen.

If you were asked to speak in a debate, "Against man-made Global Warming" you would be arguing that man is not causing Global Warming. You would have to argue that Global Warming is occurring naturally.
they will melt
If global warming affects the ozone hole, the UV will come in. This will lead to more global warming.

global warming
Global warming!

No. Global warming is caused by man burning fossil fuels and cutting down forests. No other animal does that. If there were no humans on earth, there would be no global warming.
that probibly will never happen because we are to deep into the mess of global warming to expect much change for the better.
Because the things they invent are the daily needs of people. And anyways, In my opinion... global warming is GOING to happen, No questions asked (:
