OK, now that we want to participate in the globalwarming awareness2007 project, we must first know what that term means. A quick tour to wikipedia gave this description:
The term “global warming” is a specific case of the more general term “climate change” (which can also refer to “global cooling,” such as occurs during ice ages). In principle, “global warming” is neutral as to the causes, but in common usage, “global warming” generally implies a human influence. However, the UNFCCC uses “climate change” for human-caused change, and “climate variability” for other changes. Some organizations use the term “anthropogenic climate change” for human-induced changes.
If you want to know more, here is the link to the wiki entry.
