I can't believe there are people out there that are soo blissfully ignorant and unaware of the damage being done to the in environment as we speak. Go look at the top of a coal fired power station or the tailings that mines put back into the waterways. Would you like to breathe what's coming out the top of the power station or drink from the water that is contaminated? Skeptics can go bury their heads in the sand just as long as they promise to keep them there. Climate change is not "ah we have had 2 degrees hotter on average for march", climate change is the GRADUAL changing of weather patterns and our climate due to many factors both natural and anthropogenic. Climate change is a natural phenomena however it is being accelerated by some human activities. In saying this my personal opinion is that the carbon tax is completely wrong. I have studied economics and what they are trying to do is very simple and in theory it works well, but in practice, in this economy now it is a complete nightmare. They are trying to promote structural adjustment to cleaner energy and more environmentally friendly ways of doing things. However in practice they money will not be spent on renewable energy or environmentally friendly ways of doing things rather it will just inflate prices for consumers and drive up the cost of living. If the government was serious about climate change they would reduce our reliance on mining, coal fired power stations, water recycling plants that are powered by clean energy ect.
