It is almost summer in Australia, with December marking the start of traditionally fairly hot summers on the east coast...yet today it's snowing in the town of Ballarat Victoria, after it basked in almost 40C tempuratures yesterday. There are no stable weather patterns anymore, anywhere in the world. It is unheard of to have snow in a place that is renowned for being hot at this time of year. After todays snow reports and seeing the photos, I am starting to truly believe a growing number of scientists predicting that we may be coming into another Ice Age in the near future due to recent global warming. Australia is suffering terribly from drought, the worst drought on record, now it seems to be taking on another ill turn. I'm not normally a pesimist, but the evidence is clearly there! Not just in the facts, but it's also a certain uncomfortable 'feeling' from mother nature I have had for a while now. Are there any academics, scientists or like minded people reading this that also believe in this prediction? Please share your thoughts...
