Climate change: sex change

NZ’s iconic tuatara are threatened by climate change. I’ve got the full story in Hot Topic (the book), but Reuters have beaten me to press. Tuatara eggs incubated above 21.5ºC become males, and climate change is already producing a sex imbalance in the population. Male tuatara on a predator-free island near the top of the South Island already outnumber females by 1.7 times, reports Victoria University researcher Jennifer Moore. Full story on TVNZ and the UK Telegraph.

Aussie carbon trading: big bikkies for grandad?

John Howard’s Task Group on Emissions Trading has produced its report [PDF]. It concludes that an emissions trading regime is the way forward for Australia, but fails to suggest targets. It’s a very useful overview of how carbon trading mechanisms might be made to work, but has clearly been hamstrung by the current political realities in Australia. It remains to be seen how John Howard, with his noted aversion to targets for greenhouse gas reductions will handle setting up a trading scheme if re-elected – or how he will be able to ignore section 7.2.1.

Adopting a credible long-term aspirational goal for national emissions reduction is critical. It sets the framework for Australia’s overall abatement efforts. Such a goal could be described in terms of the percentage reduction in emissions from a particular point in time, or in terms of the maximum number of tonnes of CO2-e that Australia is aiming to emit by a particular year.

The scope for handouts to industry through grandfathering, as has effectively happened in Europe, is huge. BBC Radio 4’s File On Four claims that the EU’s carbon trading scheme has increased electricity bills, given a windfall to power companies and failed to cut greenhouse gases:

Power generators received their allowances free of charge but were allowed to reflect the value of those in increased prices to customers, as if the companies had actually had to buy the allowances. Energywatch believes this increased electricity bills by about 7% in 2005. And according to one government estimate, that delivered windfall profits of up to £1.3bn to the generators in that year – higher than environmental campaigners had claimed last year.

No Right Turn has an interesting post on how this problem might be addressed in NZ, warning that badly set up emissions trading schemes amount to taxpayer handouts to emitters.

Pet food or power?

This week’s Economist has an excellent special report on business and climate change. The leader discussing the issue reminds me just how incisive the magazine can be:

There’s scope for new investment. In 2003, the most recent year for which figures are available, America’s power-generation business, arguably the world’s biggest single polluter, spent a rather smaller proportion of its revenues on R&D than did America’s pet-food business.
