Climate Change- how much impact do humans have on the weather?

The ever present debate on Climate Change continues.

Some scientists see it as an excuse for left wing parties to win votes, by devoting money and processes to climate control.

Global warming is a hot topic. Those in rural Australia, suffering droughts of severity are desperate for a solution.

Fisheries officers are the same, the reef is being destroyed and warm weather is driving the fish south, and killing others.

There is no question that the earth is heating up- the question is, how much do people impact the change? Some scientists believe that it is a natural cycle, and use proof e.g. as 30 years ago people were worried about the earth being too cool.

Others say, we are thousands of years overdue for an ice age and should consider ourselves lucky because with global warming, we will lose a few cities over sea rise, with an ice age, we could lose half the planet (I think this is pretty silly- global warming can trigger an ice age anyway!)

It is quite interesting how much government parties use global warming as a scare factor though.

I've been doing a bit of work for an environmental services company in Sydney and here's something funny- people use more energy switching on and off the lights than if they had just left it on. So there you go!
