Global warming already known for years

My Interest in the Climate problems started a couple of years ago, when I read this article in the newspaper. Nothing new if you read this now. But this article was published almost 3 years ago (before most people were talking about global warming and people have never heard of a person called "Al Gore"). At that moment I've cutted this out because I found it pretty remarkable. I've always been fascinated about inventions that people do to make this a better world, but in the end, it turns out that it makes the world even worse. Global warming is for my opinion one of the negative results of all super-inventions of human kind.
(Maybe it's also because of my great predilection for australie that this specific article drew my attention, but this doesn't matter.)
When the article was published, nobody payed attention to this topic, now it's a topic were everybody talks about. Media had a very important influence on this. Although the movie "An Inconvenient Truth" had a lot of criticism, it opened the eyes of people, and global warming became a topic of worldwide discussion. Not a bad thing at all.
At the moment I'm wondering how the story will continue. Some people are laughing this away, other people are predicting large disasters.
Although I don't know what exactly to expect, I'm convinced that health problems and natural catastrophes will grow in amount.
