Global warming???

[violet lightning]

What do you think about "Global Warming"?

My thoughts in a nutshell are I tend to think its a big red herring.
Maybe we are warming the planet slightly, but I also know anything man does is dwarfed by nature. Think about the massive volcanoe eruptions in the 19th century, like Krakatowa. It actually caused a "nuclear winter" for several months world wide. (known as "The Little Ice Age")Thankfully, man hasn't even come close to doing that. According to some scientists, some volcanoes spew more gases and debris in a few days than man has in 10,000 years.
In my fairly short life span, I have heard scientists warning about "global cooling", and then "global warming" and saying that the coastal areas were going to flood in just a few years. (this was back in the late 70's!)
Maybe the world is warming, maybe its not. Maybe its the sun.
To me, the interesting thing is that most scientists and climatologists seem to agree that the earth is actually in a fairly temperate and calm period between major ice ages. So even if we are warming the planet slightly, aren't we actually helping forestall the eventual and inevitable next ice age?

(I'm not saying man has no effect, obviously we do, but in the case of Global warming, I'm not sure we are the sole or even main culpret-)
