Professor Bob Carter:
Fact 1. A mild warming of about 0.5 degrees Celsius (well within previous natural temperature variations) occurred between 1979 and 1998, and has been followed by slight global cooling over the past 10 years. Ergo, dangerous global warming is not occurring.
Fact 2. Between 2001 and 2010 global average temperature decreased by 0.05 degrees, over the same time that atmospheric carbon dioxide levels increased by 5 per cent. Ergo, carbon dioxide emissions are not driving dangerous warming.
Fact 3. Atmospheric carbon dioxide is beneficial. In increasing quantity it causes mild though diminishing warming (useful at a time of a quiet sun and likely near-future planetary cooling) and acts as a valuable plant fertiliser. Extra carbon dioxide helps to shrink the Sahara Desert, green the planet and feed the world. Ergo, carbon dioxide is neither a pollutant nor dangerous, but an environmental benefit.
Fact 4. Closing down the whole Australian industrial economy might result in the prevention of about 0.02 degrees of warming. Reducing emissions by 5 per cent by 2020 (the government’s target) will avert an even smaller warming of about 0.002 degrees. Ergo, cutting Australian emissions will make no measurable difference to global climate.
Fact 5. For an assumed tax rate of $25 a tonne of carbon dioxide, the costs passed down to an average family of four will exceed $2000 a year.

Meanwhile, the US scraps any notion of a carbon tax.
