Alarming inconsistency: NSW Government Ministers on development in flood-prone areas
The floods on the eastward-flowing rivers of New South Wales have abated, but when they were at their height there were some alarming differences between state government ministers on the important matter of development on the floodplains of the Hawkesbury-Nepean River system…. Continue reading »

Seriously ugly: here’s how Australia will look if the world heats by 3℃ this century
Imagine, for a moment, a different kind of Australia. One where bushfires on the catastrophic scale of Black Summer happen almost every year. One where 50℃ days in Sydney and Melbourne are common. Where storms and flooding have violently reshaped our coastlines, and unique ecosystems have been damaged beyond recognition – including the Great Barrier… Continue reading »

The meaning of the word ‘floodplain’ – and the consequences of building on one
One of the great challenges of city building is building sustainably. Many of our towns and cities are built at least in part on floodplains, which are by definition problematic as places on which to build…. Continue reading »

Climate crisis solutions need to address the web of causes
Climate change has no single cause. It has resulted from the interconnected web of population, consumption, technology, and the political economy. The climate emergency requires us to recognise and grapple with this web sooner rather than later…. Continue reading »

Re-thinking flood mitigation and development, especially in the Hawkesbury-Nepean Valley
The rain has gone, the floods on the eastward-flowing rivers are receding in Queensland and New South Wales and the focus has shifted from response to recovery. But there’s another important matter which needs to be addressed mitigation, or the means by which we can reduce the impacts of future flooding. Let’s look at this… Continue reading »

Yes, Australia is a land of flooding rains. But climate change could be making it worse
Over the past three years, I’ve been working on the forthcoming report by the United Nations’ Intergovernmental Panel on Climate Change. I’m a climate scientist who contributed to the chapter on global water cycle changes. It’s concerning to think some theoretical impacts described in this report may be coming to life – yet again – in Australia…. Continue reading »

Climate war’s Catch 22: We need targets before we can deploy technology
There is a terrible circularity about saying we will only commit to a target when we know the technological path to reaching it. This is because the development of new technologies and their actual deployment, depends on governments having goals (aka targets) and signalling their firm intention to stick to them….

The Australian newspaper: Decades of disservice to climate science, education
In the penultimate paragraph of my 2020 essay 40 Years of Climate Warnings ignored by Australian politicians, I presented a “rogue’s gallery” which included the Murdoch media for waging war against climate science over more than two decades. This article explores a rather extraordinary, decade-old episode in the climate wars involving the Australian newspaper which… Continue reading »

Snow storms in North America and Europe: real-time consequences of climate change
Snow storms in North America and Europe may give the impression that “global cooling” is taking place. Nothing is further from the truth. The cooling is a consequence of the weakening of the Arctic jet stream boundary, allowing freezing air masses to flow out of the Arctic circle…. Continue reading »

Australia’s plans for a $2 billion airstrip in the Antarctic is environmental vandalism
While Australia criticises other countries for their supposed expansionist policies, Australia is the most brazen of any country in asserting ownership of territory that doesn’t belong to it. And while Australia claims to be staunchly committed to the environmental protection of the Antarctic, its actions belie such a claim, with its proposal to build a… Continue reading »

Santos changes tack: rugby charm offensive replaces lobbying efforts
The issue of gas extraction in the Pilliga, in north-west NSW, has caused conflict.

The pandemic is climate change on fast forward
The think tank idea that the world can still make a gradual transition to a low-carbon world by tweaking neoliberalism is totally unrealistic. We need to undertake a massive risk management task, the first step of which must be a brutally frank assessment of the challenge we face. It is something that business, finance and… Continue reading »
