Chuboy, I reckon that an ice age is a pretty clear cut and extreme example of climate change.
By the way, unless you want to go and live in a commune in Nimbin, there is NO WAY that you can avoid paying this carbon dioxide tax. As stated earlier in this thread, unlike a GST which is imposed upon the end user, this impost will be layered at every stage of production. By the time you consume your goods and services, you WILL be paying.
The most invidious part of this process is that a company may be the most energy efficient producer of goods on the planet, however by the time that you end up buying their product, the price that you pay will include several layers of carbon dioxide tax ie: the transporter, the wholesaler and then the retailer will all add an additional cost to your item as their way of apportioning their cost of this tax.
At least a GST is clear cut and only imposed once
