The debate about the economics of nuclear energy versus renewable energy has distracted politicians, the media and members of the public from the physical hazards of nuclear energy. The three principal hazards are its contribution to the proliferation of nuclear weapons, the risk of nuclear accidents, and the impossible task of managing nuclear wastes for 100,000 years. This article offers a concise review, drawing attention to some issues that are not widely known, including a fourth hazard, radiation exposure of the unborn child. I write wearing the hat of a physicist. (more…)

Public letter to my MP about Israel’s actions in Palestine
Dear Julian Leeser MP, I live in your electorate, Berowra. In this letter I respond to your statement in your newsletter: “These differences [between the major political parties] are most notable on Israel and Ukraine where we have failed to stand by our values and stand with our friends as previous governments both Labor and Liberal have done.” (more…)

Consumption is driving global greenhouse gas emissions
Patrick Mazza has offered a valuable analysis of China’s contribution to global greenhouse gas (GHG) emissions and what it is doing, and still needs to do to reduce them. However, like the vast majority of scenarios on mitigating GHG emissions, it doesn’t address the elephant in the room, the growing growth in consumption in China and in the whole planet. Economic growth is closely correlated with the growth in consumption of energy and emissions. (more…)

Sustainability scientists challenge the dominant economic system
It is a rare event when scientists directly challenge the theory, political power and cultural embeddedness of conventional economics. And yet such a challenge is needed because neoclassical economics theory and neoliberal economics practice together form one of the principal driving forces of environmental destruction and social injustice.

Planned degrowth is needed to stop the collapse of civilisation
An opinion piece (‘Degrowth approach is disastrous’, Canberra Times, 9 September, p.38) by authors from the Centre for Independent Studies (CIS) attacked the concept of degrowth to a steady-state economy (SSE) and defended the notion of continuing economic growth on a finite planet. (more…)

The transition to a steady-state economy: a reply to Michael Keating
Scientific research shows that the environmental impacts of human civilisation have exceeded several planetary boundaries. To avoid societal collapse and to assist the transition to an ecologically sustainable civilisation, we must transition to a steady-state economy. (more…)

Reduce consumption, or face reality of civilisational collapse
An important debate is developing in Pearls and Irritations on the need to reduce consumption. In his article “Labor’s Environmental Denialism”, Stephen Williams acknowledged several positive steps being taken by the Labor government to help protect the environment, and then argued that Labor was failing to address the fundamental drivers of environmental disaster, which he identified as growth in the economy and population.

The nuclear industry’s updated songsheet remains outdated
The campaign for nuclear power stations in Australia defies the unstoppable rise of renewables and should be rejected by governments and the electorate — it’s a technology whose time has passed. (more…)

The politics of reaching net-zero
Rapid technological change is necessary but not sufficient to avoid dangerous climate change. Policies to encourage selective consumption and reduced total consumption are also needed.

Peter Garrett gives Labor a free pass on climate action
Peter Garrett’s essay in ‘Upturn: A better normal’, edited by Tanya Plibersek, rightly castigates the federal government’s continuing support for fossil fuels and its failure to implement effective climate mitigation policies. But he doesn’t address Labor’s reluctance to take the strong action demanded by climate science or identify the policies needed. (more…)

Economic Recovery from Covid-19 while mitigating Climate Change
Green growth, based on technological change, is necessary but not sufficient for effective, timely, climate mitigation. It must be supplemented by reducing the material consumption of the rich countries. (more…)
