What happens when we can detect nuclear subs?

New details of the AUKUS defence and security pact have revealed Australia will buy three second-hand US Virginia-class submarines early next decade (and potentially two more), subject to approval by US Congress.

Australia will also build a fleet of eight nuclear-powered SSN-AUKUS boats at Adelaide’s Osborne Naval Shipyard. The first will be delivered by 2042, with five completed by the 2050s, and construction of the remaining three going into the 2060s.

It’s estimated the program will cost between A$268 billion and A$368 billion over the next three decades.

Make no mistake. Modern submarines, especially nuclear-powered ones, are one of the most potent and effective weapon systems in today’s world. That is, until they aren’t.

Our analysis shows they might soon be so easily detected they could become billion-dollar coffins.

Subs in the ocean are large, metallic anomalies that move in the upper portion of the water column. They produce more than sound. As they pass through the water, they disturb it and change its physical, chemical and biological signatures. They even disturb Earth’s magnetic field – and nuclear subs unavoidably emit radiation.

Science is learning to detect all these changes, to the point where the oceans of tomorrow may become “transparent”. The submarine era could follow the battleship era and fade into history.

Barngarla have their say in court

Monday March 6th: People gather at the Federal Court hearing to support Barngarla people
3 Angas St, right next to Victoria Square / Tarntanyangga (south-east cnr of Victoria Square / Tarntanyangga)

 

Here are some things that you can do to support:

 

Climate Justice

We need responses that are truly intersectional. So how about as we decarbonise and create a less polluted world, we also build a much fairer society on multiple fronts?
Many environmentalists hear that and think: “Well, that sounds a lot harder than just implementing a carbon tax or switching to green energy.” And the argument we make in the climate justice movement is that what we’re trying to do is to build a power base that is invested in climate action. Because if you’re only talking about carbon, then anybody who has a more daily emergency – whether it’s police violence, gender violence or housing precarity – is going to think: “That’s a rich person problem. I’m focused on the daily emergency of staying alive.” But if you can connect the issues and show how climate action can create better jobs and redress gaping inequalities, and lower stress levels, then you start getting people’s attention and you build a broader constituency that is invested in getting climate policies passed.
I don’t believe we have the luxury of throwing up our hands and saying: “We’re doomed, let’s just go Mad Max on this.” I think there are ways of preparing for those shocks, that build a way of living with one another that is significantly kinder and more generous than the way we currently live with one another, which is really quite brutal. That requires investing in the labour of care at every level, and guaranteeing basic economic rights, like the right to housing, food and clean water. If we build out that infrastructure, we can weather shocks with far greater grace. That’s where I place my hope.

Will we follow Belize? The UN just confirmed the Great Barrier Reef is in Danger

What just happened?

The Great Barrier Reef has been World Heritage listed since 1981. This means it’s considered an area of outstanding value to humanity. Covering an area the size of Italy, this iconic area includes some 3,000 separate reefs, over 1,000 islands and a variety of other significant habitats.

The latest UN mission has just reported back, finding the reef’s condition is worsening and recommending it be listed as “in danger”. It also offered practical solutions.

Previous governments have fought to ensure the reef is not listed as in-danger despite their own five-yearly reviews demonstrating an obvious decline. In 2009, the reef’s condition was rated poor and declining. In 2014 it was poor and declining and in 2019, very poor and declining.

So the government knows the reef is in danger. We know, and the tourism industry knows. While some tourism operators worry about their business, the opposite appears to be true: more people go, thinking it might be their last chance to see it. And already, operators are adapting by taking tourists to areas still in good condition.

Federal governments just don’t want the reef on the list because of the hit to their international reputation – and to their domestic standing.

If the reef is officially listed as “in danger” next year, it will draw a much greater focus to the reef’s plight. And that may help galvanise effective national and global action.
Take the case of the famous coral reefs of Belize in Central America. When these reefs were listed, the government banned nearby oil exploration and protected mangroves. Belize’s reefs have now been taken off the in-danger list.

“Galilee Basin should not go ahead”

Professor Justine Bell-James, Uni of Queensland, comments on an important court ruling

In a historic ruling [on Friday Nov 25th], a Queensland court has said the massive Clive Palmer-owned Galilee Basin coal project should not go ahead because of its contribution to climate change, its environmental impacts, and because it would erode human rights.

The case was mounted in 2020 by a First Nations-led group of young people aged 13 to 30 called Youth Verdict. It was the first time human rights arguments were used in a climate change case in Australia.

The link between human rights and climate change is being increasingly recognised overseas. In September this year, for example, a United Nations committee decided that by failing to adequately address the climate crisis, Australia’s Coalition government violated the human rights of Torres Strait Islanders.

Youth Verdict’s success  builds on this momentum. It heralds a new era for climate change cases in Australia by youth activists, who have been frustrated with the absence of meaningful federal government policy.

1.58 billion tonnes of emissions

The Waratah Coal mine operation proposes to extract up to 40 million tonnes of coal from the Galilee Basin each year, over the next 25 years. This would produce 1.58 billion tonnes of carbon emissions, and is four times more coal extraction than Adani’s operation.

While the project has already received approval at the federal government level, it also needs a state government mining lease and environmental authority to go ahead. Today, Queensland land court President Fleur Kingham has recommended to the state government that both entitlements be refused.

In making this recommendation, Kingham reflected on how the global landscape has changed since the Paris Agreement in 2015, and since the last major challenge to a mine in Queensland in 2016: Adani’s Carmichael mine.

She drew a clear link between the mining of this coal, its ultimate burning by a third party overseas, and the project’s material contribution to global emissions.
