The CSIRO has found, in a paper yet to be peer-reviewed or quality controlled (let's get the propaganda out before we check for accuracy) that a carbon tax of about $30 per tonne would allow much of the Murray Darling Basin to return to forest providing a huge carbon sink for the nation in our quest to reduce the world's temperature by 0.000005 degrees.

Oh just a minor detail that the Government would have to provide incentives such as a cheap trees and subsidies, but it could happen. Farmers could be persuaded to abandon agriculture for forestry.

Great idea! And what would we do for food? Taking productive land out of the business of production means that we have to get our food from somewhere else- possibly from somewhere in Asia where they might be cutting down their native forests to produce food for us to import.

I used to have a lot of respect for the CSIRO as a science organisation but these days there seems to be very little thinking going on.
