1st of all there is no such thing as global warming, it is a term coined by the media and used by those who haven’t a clue what they are on about.
I wouldn't disqualify the people who use the term "global warming" like that. Scientists use the term, too. Your statement that there is no such thing like global warming is a joke. Of course there is a clear upward trend in the global average temperature (as written in the article posted), and an upward trend in global temperature can be called global warming.
Regarding the difference of the two terms, this is a good link:

But the point I absolutely agree with you is that a lot of people are more interested in benefitting from the topic themselves instead of providing objective information about it.
