There are two theories, they both start with "in the beginning there was nothing". One theory then goes on about a "Big Bang" while the other talks about a "Supreme Being".
Add a few billion years for one theory (or 5000 years for the other), and you will see that there were ice ages on earth way before Man was here. Between the ice ages was, yes, you guessed it; "GLOBAL WARMING". We don't really know what started the ones that occurred before man, just like we don't know what started this recent warming period (which, by the way, is still cooler than many other periods in earths history).
So there you go, any one who says they know what started it doesn't (and by the way, ask someone in their 50's about how man's pollution was going to cause global cooling" - at least thats what all the "scientists" saying in the 60's).

Global warming has been a natural part of our climate since the atmosphere formed. Without the greenhouse effect earths average temperature would be a constant -18 degrees C (or 0 F). What is happening now is that we are seeing the effects of gasses released into the atmosphere, the equivalent of putting thicker glass in the greenhouse, by humanity, changing earths climate. This global warming began when humanity began using fossil fuels at the dawn of the industrial revolution some 250 years ago.
The effect will be different depending on where you live. Where I live (Sweden) it has been getting warmer and wetter constantly the past years following the prognosis of climate change spot on. It hardly snows at all before January anymore.
For poorer countries in the subtropics global warming will be extremely devastating. They would suffer greatly from a hotter, drier climate. Some nations are actually disappearing as oceans levels are increasing.
Al Gore has said many of these things in his film but all he has said has been said for decades. So Al Gore isn´t wrong, just very late and behind the times. The rest of the world already knew all that. It is truly pathetic that some refuse to see the obvious proof to the reality of global warming just because they have personal issues with Al Gore.

One could postulate that it began with the formation of the solar system and Earth. It would seem more reasonable to say it began when Earth differentiated and began to cool down and resemble the planet as we think of it.
Global warming and cooling are natural cycles that Earth has been going through for a long long time.

Global warming is a natural cycle of the Earth caused by the rise and fall of CO2 levels this one we are in is being artificially fed by our pollution.
The natural cycle is now out of control and the most extreme seen since the forming of the Himalayan Mountains.

First there were particles that began coalescing. The mostly hydrogen condensed into a big ball and eventually ignited with fusion. Some outer swirls of particles also coalesced and formed planets. Some of the planets retained atmospheres and then there was warmth.

Since there is no such thing as Global Warming, it has not started yet. Don't believe the lie or Al Gore!

Al Gore invented it shortly after the Internet thing, it just took a few more years to catch on.
