How about that hiatus?

John Quiggin132 Comments

The US National Oceanic and Atmospheric Administratioh has just released its global climate analysis for May 2015. The results

May 2015 was

* The warmest May on record globally
* The warmest May on record on land
* The warmest May on record on the oceans
* The warmest May on record in the Northern Hemisphere
* The warmest May on record in the Southern Hemisphere

Also, the warmest March-May, Jan-May and (I think) 12-month period in the record.

Comment is superfluous, but don’t let that stop you.

An optimistic view on climate change

John Quiggin65 Comments

Regular readers will be aware that I have a generally optimistic disposition. You may wish to bear this in mind when you read this Inside Story piece arguing that the prospects are good for stabilising global greenhouse gas concentrations at 450 ppm.

On the whole, though, I think excessive pessimism is a bigger problem than over-optimism. As I’ve argued before, I think lots of people have locked themselves into positions (eg advocacy of geoengineering, or belief in the end of industrial civilisation) that are based on the assumption that stabilisation is impossible. Many of these people are not open to evidence that stabilization is feasible, and even likely.

There’s a strong case that we should do better than 450 ppm, with a common ‘safe’ figure being 350 ppm. Since we passed that level some time ago, that requires a long period of negative net emissions, which cannot easily be achieved with current technology. Still, if net emissions are reduced to zero in the second half of this century, and some technological advances are made over the next fifty years (a plausible assumption if we put in some effort), even 350 ppm might be feasible.

Australia is dragging the chain under the Abbott government, but even Abbott seems to be feeling the international pressure judging by recent reports. With luck the last couple of years will turn out to have been a temporary detour in progress towards decarbonization.

To help poor people, give them money (Draft excerpt from Economics in Two Lessons)

John Quiggin97 Comments

Here’s another draft excerpt from my book in progress, Economics in Two Lessons. To recap, the idea of the book is to begin with the idea that market prices represent opportunity costs for the households and business who face them (Lesson 1), and then go on to explain why market prices won’t in general equal opportunity costs for society as whole (Lesson 2). A lot of the book will be applications of the two lessons, and this section is an application of Lesson 1.

As before, all kinds of comment and criticism, from editorial points to critiques of the entire strategy are welcome.

John Locke, an enemy of freedom

John Quiggin65 Comments

“Freedom Commissioner” Tim Wilson has been quoted in The Australian saying that Australian schoolchildren ought to learn more about classical liberal theorists like John Locke. While loath to squeeze yet more material into an already overcrowded curriculum, I’d certainly be glad if there was more awareness of Locke’s actual ideas and actions, as opposed to his prevailing image as an early apostle of freedom. A proper treatment of Locke would have to explain how

* His theory of natural rights in property was designed to justify the expropriation of indigenous populations
* His advocacy of freedom included support for slavery
* His theory of religious toleration excluded atheists and Catholics
* His theory of political freedom did not extend to freedom of speech.

How then did Locke get such a high reputation? The answer isn’t all that mysterious. Locke was closely involved in the British colonisation of North America, both as an investor and as a participant in political activity such as the drafting of the Constitution of the Carolinas, which ratified the expropriation of the indigenous population and enshrined the absolute power of slave-owners.

When the slave-owning colonists achieved independence from the British Crown, it was natural for them to look to Locke to provide the basis for their political theories (theories that did not preclude the passage of the Alien and Sedition Acts restricting political freedom). Locke then benefitted from the same historical amnesia that has absolved all the US founders from their role in maintaining and extending slavery.[1]

Instead of Locke, it might be better for students to learn about that old-fashioned Tory, Dr Samuel Johnson, who remarked “How is it that we hear the loudest yelps for liberty from the drivers of Negroes”, and whose friendship with his Jamaican servant, Francis Barber, a former slave, was a striking testimony to his character.

fn1. of course, the American Revolution embodied much nobler hopes than those of the Southern aristocracy that dominated the early years of the United States. Realising those hopes took decades of struggle and a bloody civil war.

Big Oil changes sides in the War on Coal

John Quiggin44 Comments

As the time left to save the planet from uncontrolled climate change gets shorter and shorter, the previously glacial pace of movement on the issues has speeded up. One of the most important, and surprising, developments has been a string of increasingly sharp attacks on coal, coming from representatives of major oil and gas companies. As this (rather excitable) piece explains, the reason is simple. The policy debate has crystallised around the idea of a carbon budget – the remaining amount of CO2 that can be emitted while keeping atmospheric concentrations at levels consistent with 2 degrees of warming or less.

Obviously, if such a budget is imposed and adhered to, a lot of fossil fuel resources, currently sitting on corporate account books, will have to be left in the ground. Unsurprisingly, fossil fuel companies have done their best to prevent such an outcome, promoting science denial, and encouraging national governments to shirk their share of the burden with the argument that others should do more. Such a strategy implies a united front among fossil fuel owners, since the longer the imposition of a budget can be delayed, the better off they all are.

The recent break in the fossil fuel coalition therefore marks a new stage. Rather than try to expand the budget for all fossil fuels, the oil and gas companies have decided to get as much as possible for themselves, which means shutting down coal as fast as possible. The facts that have made such a strategic switch sensible are many and varied but the most important are

(a) the increasing recognition of the health effects of burning coal which gives national governments like that of China a strong incentive, independent of climate change, to reduce coal use
(b) the fact that the most immediately promising alternatives to fossil fuels are renewable sources of electricity which compete directly with coal, and are, to a significant extent complementary with gas (as a dispatchable source, gas-fired electricity tends to offset problems associated with the variability/intermittency of renewables.

What’s the appropriate response here? In the end, it will be necessary to phase out fossil fuel use altogether. But the logic of tackling coal first is inescapable. If that logic drives a wedge in the fossil fuel coalition, so much the better for all of us.

Monday Message Board

Another Monday Message Board. Post comments on any topic. Civil discussion and no coarse language please. Side discussions and idees fixes to the sandpits, please.

Since it’s notionally the Queen’s Birthday today, I’d be interest in thoughts about the prospects for, and politics of, an Australian republic.

Sandpit

John Quiggin35 Comments

A new sandpit for long side discussions, idees fixes and so on. Unless directly responding to the OP, all discussions of nuclear power, MMT and conspiracy theories should be directed to sandpits (or, if none is open, message boards).
