A comment I posted on Tim Blair’s blog this morning:

There are between three and four molecules of CO2 for every 10,000 particles of air.

Anthropogenic CO2 is assumed to be about 4% of that, which comes to about 14 molecules of CO2 per 1 million particles of air.

Australia’s contribution to global CO2 is assumed to be about 1.4% of the total of anthropogenic CO2.

That amounts to 0.2 molecules of CO2 for every 1 million particles of air.

If we reduce our CO2 output by 20%, destroying our transport and primary industries in the process, our contribution to global CO2 will go from 0.2 particles per million of air, to 0.16 particles per million of air.

In other words, from an indetectably tiny and insignificant amount, to a very slightly smaller insignificant amount.

And this will only cost us our competitivness in in international trade, a massively increased cost of living, and massively increased unemployment.

But, you know, feeling like we’re doing something is so important.

Go you greens!
