A climate ‘bonbon’

Depressed by the gloomy alarm of Ross Garnaut’s revised climate review? “Global temperatures continue to rise around the midpoints of the range of the projections of the Intergovernmental Panel on Climate Change (IPCC) … It is an awful reality that no major developments inthe science hold out realistic hope that the judgements of the 2008 […]

Costs and benefits of CO2 abatement

Richard Toll’s paper for the 2009 Copenhagen Climate Consensus that I mention in my previous post is well worth revisiting. It contains an excellent review of economic research on the potential aggregate costs of the warming projected by the U.N. Toll—who, as a UNIPCC lead author, is hardly a climate skeptic—estimates that global consumption and […]

A CO2 tax is the worst option

More than a month after her announcement that she intended to legislate a carbon tax, Ms Gillard has yet to give us any details of her plans. The vague and confusing Ministerial statements made while she was in Washington suggest that either this is another off-the-cuff plan for national economic infrastructure (like the NBN and […]

One thousandth of one degree

What if the climate alarmists are right and the global average atmospheric temperature emerges from its current pause to climb at a sustained rate that is unprecedentedin the past century and a half? Headed for an increase of, say, 4° celsius by 2001? How will the Gillard Carbon Tax help avoid that outcome? The short […]

Temperature trends in Garnaut 2011

I remain unconvinced by Dr Garnaut’s arguments that global average temperature trends in the past decade should, if anything, add to a sense of alarm about man-made “greenhouse-gas” emissions. There is much in the updated review that I have not had an opportunity yet to consider. (Update: There’s a more comprehensive critique of the updated […]

Would you want to live in this world?

The world that the Rudd Government’s White Paper on Climate Change, and Julia Gillard but not the original (2008) Garnaut Report aspired to—where CO2 emissions are cut rapidly so that atmospheric concentrations fall below 450 ppm—has been described by the International Energy Agency in terms that show it would be colder, poorer and hungrier: ” […]

Firms may ‘bank’ compensation

The MD of Rio-Tinto Australia this week complained that firms seeking compensation for the impost of carbon taxes on exports are unfairly characterised as “rent seekers”. But, there is persuasive evidence from Europe that large firms there have made windfall profits by banking the compensation they were offered under the EU carbon abatement scheme while […]
