I also agree that climate change is a better term. First, the world gets warm enough to melt the ice caps. The cold water goes into the ocean and changes weather patterns, generally making them more severe. That means hotter hot days and colder cold days. The world moves from moderation to extremes. When the melted ice caps cause too much cold water to spread, the thawing slows. Eventually, water freezes into ice again, but this time it is too much. The freezing spreads, and continents become covered in a bitter ice age. Time thaws the ice, but that takes eons.
It is not caused by man, but man contributes to it for the first time in world history. Pollutants that naturally occur in nature are multiplied. We do not know for certain how much this affects the cycle, but we know that pollutants created by human industry affect Earth in ways that tend to make local environments warmer. That is why they called it global warming.
I want to be clear when I point out that I don't know whether we are making it worse. One thing is for sure. My Camaro is awesome, and so are all of yours!
