The fiduciary responsibility of politicians and bureaucrats in the era of existential climate risks

“Fiduciary: a person to whom power is entrusted for the benefit of another”“Power is reposed in members of Parliament by the public for exercise in the interests of the public and not primarily for the interests of members or the parties to which they belong. The cry ‘whatever it takes’ is not consistent with the performance of fiduciary duty”

After three decades of global inaction, none more so than in Australia, human-induced climate change is now an existential risk to humanity. That is, a risk posing large negative consequences which will be irreversible, resulting inter alia in major reductions in global and national population, species extinction, disruption of economies and social chaos, unless carbon emissions are reduced on an emergency basis.

The risk is immediate in that it is being locked in today by our insistence on expanding the use of fossil fuels when the carbon budget to stay below sensible temperature increase limits is already exhausted.

1.5°C of warming is closer than we imagine, just a decade away

Global warming of 1.5°C is imminent, likely in just a decade from now. That’s the stunning conclusion to be drawn from a number of recent studies, surveyed below.

So how does hitting warming of 1.5°C a decade from now square with the 2015 Paris Agreement’s goal of “holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C”? In two words, it doesn’t.

The Paris text was a political fix in which grand words masked inadequate deeds. The voluntary national emission reduction commitments since Paris now put the world on a path of 3.4°C of warming by 2100 (as illustrated), and more than 5°C if high-end risks including carbon-cycle feedbacks are taken into account.

The Paris outcome is an emissions path continuing to rise for another fifteen years, even though it is clear that “if the 1.5°C limit should not be breached in any given year, the budget (is) already overspent today”. Two years ago, Prof. Michael E. Mann noted: “And what about 1.5°C stabilisation? We’re already overdrawn.”
