It seems odd doesnt it? People go on about global warming and the rising temperatures and yet some areas seem colder than normal. Thats weird! People go on about the melting icebergs and the rising oceans and then swear that were in for severe water shortages. How does that work? Global warming should cause warmer weather right? And higher oceans and melted glaciers should mean more water for the masses right? Sorry folks, but its just not that simple.
The Earth is a very large closed ecosystem. It is also dynamic, meaning it is constantly changing from one form into another. From the day that it formed from bits and pieces of rock and iron it has always been on the move, never predictable from one era to the next. When the dinosaurs walked this planet there werent any ice caps and it was a very, very hot place. The climates changed due to the effects of the animals that lived here, from natural disaster, or, more commonly, from natural processes, many of which we can barely comprehend. Over time our planet has steadily cooled to the balmy, but very comfortable blue ball on which we now reside.
In other words the world is in constant flux. Never the same from one...
