Over the long term, volcanoes emit about 5 x 10¹¹ kg of CO² to the air annually. This amount is approximately 3% of that emitted by anthropogenic activity.

Check my math. That's 500 million tonnes of CO² annually (500 times what Australia is thinking of sequestering).

One additional volcano going active in a year and Australia's efforts are for nought.

This is insanity.

I suspect you meant that the other way around, that anthropogenic activity is 3% of that emitted by volcanoes. Further, the quote from Fred Singer (above) indicates that the number is more like .3%.
