After hearing Tim Flannery being named Aussie of the Year, I thought it would be interesting to hear other peoples thoughts about global warming. I know there are alot of theories to argue on either side of the fence, so let's hear it.
Here's what I think:
I don't think there is anything we can do about Global warming, it has been occurring for millions of years long before Humans even existed. Heres my theory:
If you put a block of ice(earth) next to a heat source(sun), the block of ice would absorb the heat and eventualy melt. The smaller the ice gets, the quicker it melts - right? Does anyone follow me?
The earth is believed to be once covered with ice, then theres the ice age theories and so on. With the Earth being on a tilted axis, the polar caps are exposed to less sunlight and heat than the equator, which explains the temperatures slowly increasing from the equator towards the ice caps.
Don't get me wrong, I'm not arguing that pollution isn't trapping in heat from the sun and therefore effecting day to day temperatures. But I think it is insignificant to the bigger picture............
What are your thoughts?
