comets flying in formation in the main belt

Fragmented main belt comet is a tough one to explain given standard explanations of where comets come from and why they "fragment". Standard theory is that close encounters with the sun or planets cause excessive tidal forces which break comets apart. My theory is that the comets are already fragmented, and tidal forces from close encounters just separate the cometary "fragments" into new comets in their own right.

Carbon Tax vs emissions trading vs direct action

It is hard to discuss tax policy, or indeed anything without agreeing on premises.
There is an equivalence between a carbon tax and emissions trading with a fixed price. There is also an equivalence between a carbon tax with a variable price that is set to match the market price of emissions in an international emissions trading scheme, and being part of that emissions trading scheme.

Any scheme can be "gamed" in the sense that the European scheme allocated or grandfathered too many credits, to appease emitters and to bribe them to get in the scheme, and then allowed financial pressures of the debt crisis to further water down the scheme.

In Australia, the scheme seems scheduled to be gamed by lobbying from industrials for the tax to be scrapped. Either way, instead of acceptance, and long term plans to avoid the price efficiently by moving away from carbon intensive industries, plans are on hold on a wait and see with the hedge on what one can bet the future scheme to be. Hold back plans for renewables in the hope of a fat grant from the new "direct action" plan, rather than do what makes sense now, with the energy prices as they are with the carbon tax and assuming they will stay at the relative level.

Avoid the tax by switching to low carbon, or avoid the tax by switching the Government? I prefer the first. Grudging acceptance that the tax may effectively be there for a while. Even the thought that it will be gone soon changes the behaviour of industrials to bet on a low effective carbon price.
