The current pace of global heating risks unleashing “rapid and unstoppable” sea level rise from the melting of Antarctica’s vast ice sheet, a new research paper has warned.

Unless planet-heating emissions are swiftly reduced to meet the goals of the Paris climate agreement, the world faces a situation where there is an “abrupt jump” in the pace of Antarctic ice loss around 2060, the study states, fueling sea level rise and placing coastal cities in greater peril.

“If the world warms up at a rate dictated by current policies we will see the Antarctic system start to get away from us around 2060,” said Robert DeConto, an expert in polar climate change at the University of Massachusetts and lead author of the study.

“Once you put enough heat into the climate system, you are going to lose those ice shelves, and once that is set in motion you can’t reverse it.”

DeConto added: “The oceans would have to cool back down before the ice sheet could heal, which would take a very long time. On a societal timescale it would essentially be a permanent change.”

This tipping point for Antarctica could be triggered by a global temperature rise of 3C (5.4F) above the preindustrial era, which many researchers say is feasible by 2100 under governments’ current policies.

The new research, published in Nature, finds that ice loss from Antarctica would be “irreversible on multi-century timescales” should this happen, helping raise the world’s oceans by 17cm to 21cm (6.69in to 8.27in) by the end of the century.

If the world was able to meet commitments made in the Paris deal, however, the research found Antarctica would contribute 6cm to 11cm of sea level rise by the end of the century, on a par with the current rate of ice loss.

Under the Paris agreement, governments have vowed to limit dangerous global heating below 2C hotter than preindustrial times, with efforts to keep the increase to 1.5C.

“It’s really the next few decades that will determine the sea level rise from Antarctica,” De Conto said. “These ice shelves won’t be able to just grow back.”

Scientists have increasingly issued warnings over the fate of the huge amount of ice stored in Antarctica which, if it all melted, would raise global sea levels by 57 metres, completely submerging the world’s coasts.

While this won’t happen in any sort of foreseeable timescale, even a small increase in ice loss would be felt in global sea levels. Of particular concern is the western section of the Antarctic ice sheet, with scientists currently exploring the rate of decline experienced by the Thwaites glacier, also known as the doomsday glacier.

In a worst-case scenario, the loss of the glacier, which is about the size of Britain and 1km deep, would raise sea levels by 65cm.

Antarctica is being winnowed away by a warming atmosphere as well as the heating oceans, with warming seawater entering crevasses and gnawing away at “pinning points” that hold enormous bodies of ice to submerged bedrock.

A rapid acceleration of melting could cause a cascading effect where huge amounts of ice and water flow uninterrupted into the Southern Ocean.

Once in motion, the impacts from such dramatic ice loss would unfurl over centuries. “In the century after 2100 it’s potentially catastrophic,” said DeConto. “If we did nothing at all to reduce emissions we could get 5 metres of sea level rise just from Antarctica by 2200, at which point you’d have to remap the world from space. It would be unimaginable.”

DeConto’s paper uses a mode that incorporates temperature increase and ice loss, as well as the dynamic processes at play in Antarctica that present challenges in predicting exactly what will happen as the world continues to heat up.

Another study published in Nature on Wednesday, by scientists at King’s College in London, finds the sea level will rise by 0.5cm every year by 2100 if the global temperature rise hits 3C. DeConto said the other paper is an “impressive piece of work” but differed from his paper, which factored in compounding impacts from the loss of ice shelves.

“Neither of these papers are the last word, this is ongoing work,” he said. “Basically we are going to have to cope with continued sea level rise. The real question is whether it will be at a manageable or unmanageable rate for us.”

Orrin Pilkey, a sea level rise expert at Duke University who was not involved in the research, said the paper is an “important attempt to relate the Paris agreement to reality”.

He added: “I would consider this a thoughtful and even frightening but credible contribution which should provide a very strong basis to get on with implementation of the Paris agreement.”

Andrea Dutton, an expert in sea level rise at University of Wisconsin–Madison, who was a co-author, said the paper “addresses an important and pressing question” of what the Paris climate targets will mean for future sea level rise.

“We are already struggling with the amount of sea level rise that has occurred over the past century,” said Dutton, who added that a major acceleration in Antarctic melting will “bring about coastal retreat and migration on a scale that we have never before witnessed”.

“We will not be able to just adapt because it is impossible to just engineer our way out of this,” she said. “The conclusion is a stark reminder of the urgency in making deep and sustained cuts in our greenhouse gas emissions.”

(AU ABC) Green Hydrogen Electrolysers To Be Built In Regional Australia With Government Backing

ABC Rural - Eliza Borello | Laura Birch

Key Points
  • $100m ARENA funding will go to Engie Renewables in the Pilbara, ATCO in WA's Mid West and AGIG's Hydrogen park in Wodonga, Victoria.
  • The three projects will produce green hydrogen, using renewable energy
  • Federal Minister Angus Taylor says the hydrogen produced by ATCO and AGIG will be blended with LNG for use in gas networks
Three new green hydrogen plants have been approved in regional Australia and will share in more than $100 million worth of conditional Federal Government funding.

The Australian Renewable Energy Agency (ARENA) has awarded Engie Renewables up to $42.5 million towards a 10 megawatt (MW) electrolyser project which would produce hydrogen in Yara Pilbara Fertiliser's existing ammonia facility in Karratha in Western Australia.

Further south, at Warradarge in WA's Mid West, ATCO has won up to $28.7 million towards a 10 MW electrolyser for gas blending at its Clean Energy Innovation Park.

Australian Gas Networks Limited (AGIG) was set to receive up to $32.1 million towards a 10 MW electrolyser for gas blending at AGIG's Murray Valley Hydrogen Park in Wodonga, Victoria.

While all of the electrolysers would produce green hydrogen, the type preferred by environmentalists, Energy Minister Angus Taylor said the ATCO and AGIG produced hydrogen would eventually be blended with non-renewable liquefied natural gas.

"This is about blending hydrogen into our gas network, so the purpose of this is to actually bring the carbon emissions of our gas network down," he said.
"The key here is for us to build the infrastructure and to get the R & D [Research and Development] done so we can get the costs down, we can provide the supporting infrastructure and then the private sector can invest on the back of that."

The Government said the projects were expected to create more than 210 jobs during construction.

The project proponents must satisfy a number of conditions, including achieving financial close, before Commonwealth funding is provided.

Good energy policy needs to match investment Australian Hydrogen Council chief executive Fiona Simon welcomed the funding and said building some of the biggest electrolysers in the world would put Australia on the global hydrogen map.

"This type of investment is the boost that the industry needs to progress commercial, large-scale projects," Dr Simon said. 
"This investment should be matched with good policy to encourage demand and improve the economics of producing hydrogen, which will ultimately increase supply of hydrogen."
 While the funding has been approved, ATCO said it would wait until December 2022 before making a final investment decision on its Warradarge project.
AGIG's general manager Craig de Lane said his company planned to reach a financial close for its Wodonga project and start construction by early 2022.

A Yara Pilbara Fertiliser spokesman said he expected a final investment decision to be made within months, construction starting by the end of 2021 and the plant to be operational by 2023.


Green hydrogen is billed as the new climate friendly fuel in town but will it work?

Potentially bigger than LNG The news of Engie's successful bid for an electrolyser in the Pilbara was welcomed by the Karratha and District Chamber of Commerce and Industry President, Tony Simpson, who said he believed hydrogen had the potential to be bigger than LNG.

"One of the key issues for around Karratha and the Pilbara in general is [having] another industry."

"We're known for iron, we're known for mining nickel, gold, and LNG and now we're going into hydrogen which is another whole project and another economy in itself," he said.

"The spinoff back to the town will be huge in terms of job opportunities and what we're trying to do in Karratha is make it a liveable city."

Woodside and BHP miss out Gas giant Woodside missed out on its bid for funding for its proposed H2TAS hydrogen project at Bell Bay in Tasmania.

BHP's funding application for a 10 MW green hydrogen electrolyser at its Kwinana Nickel Refinery was also unsuccessful.

A Woodside spokeswoman congratulated the successful proponents and said the company remained committed to H2TAS.

"We have had a longstanding target of final investment decision for H2TAS Phase 1 in the second half of 2021," she said.

"Today's announcement from ARENA does not mean the end of the H2TAS opportunity, and we will now undertake further review of the concept and schedule."

(Financial Times) Climate Change: Australia Wrestles With Its Coal Mining Dilemma

Financial Times

Even as demand falls, federal and state governments are pumping billions into the polluting fossil fuel industry

Newcastle, Australia
- For more than 200 years, workers at the Port of Newcastle have loaded ships with coal dug out of nearby mines for transport to Asia and beyond. But with global action to tackle climate change set to decimate the trade, the management at the world’s biggest coal port is preparing for a future without the fossil fuel that generates 60 per cent of its revenues.

 “The future of coal is obviously questionable and we have to prepare for that,” says Roy Green, chair of the port, which is a gateway to the Hunter Valley, a coal mining region 280km north of Sydney. “We are likely to see a continuing flattening of coal volumes through the port and ultimately a decline, as the world switches away from coal-fired power.”

The acknowledgment that coal, which is more polluting than any other fuel source, has a shrinking lifespan is an accepted fact in many boardrooms and mining communities in Europe, the US and China, where preparations for an energy transition away from fossil fuels are already under way.

But in Australia, the world’s second-biggest exporter of coal by volume, discussions around phasing out fossil fuels remain contentious and risk inflaming the nation’s “climate wars” — a bitter 15-year battle between conservatives and progressives which has contributed to the ousting of three prime ministers in recent years.

The government is resisting international pressure to commit to net zero emissions by 2050 and has ruled out charging polluters by setting a price on carbon. It opposes the early closure of ageing coal-powered electricity plants — arguing that relying too much on renewables could lead to power cuts — and recently funded a feasibility study on whether to build a new coal plant in Queensland.


“We will not achieve net zero in the cafés, dinner parties and wine bars of our inner cities . . . [or] by taxing industries, that provide livelihoods for millions of Australians, off the planet,” Scott Morrison, Australia’s prime minister, told a business audience on April 20. Days later Morrison snubbed a request by Joe Biden, the US president, to join other nations in pledging deeper emissions’ cuts.

Instead it is the decisions being taken by the world’s biggest coal consumers to commit to a net zero emissions target by 2050 in the case of Japan and South Korea, and 2060 for China, that could act as a catalyst for change in Australia, say critics.

In a growing number of companies and communities across Australia, the discussion is changing from how to save coal to the need for a just economic transition to compensate for the loss of well-paying mining and related jobs. Many fear that if this does not happen, companies will go bust and people will suffer unnecessarily.

Energy Australia, a utility, announced in March that it would close a coal fired plant in the Latrobe Valley in 2028, four years earlier than originally planned. AGL, Australia’s largest utility, is also planning to split off an electricity generating division dominated by coal-fired power stations, a recognition that fossil fuels have fallen out of favour with investors.

Some miners, including Rio Tinto and BHP, have either already exited the market for thermal coal — commonly used in electricity generation — or signalled their intention to do so. A collapse in price to $50 per tonne in the second half of 2020 due to weak demand linked to the coronavirus pandemic and import restrictions slapped on Australian exports by China have further raised doubts over the future of the Hunter Valley’s 40 mines, which support about 16,000 jobs.

Critics warn there is an urgent need for Canberra to show leadership and plan an orderly transition to guarantee cheap and stable power, help coal mining regions diversify their economies into areas like agriculture and ensure Australia does not miss the opportunity to become a leader in green energies.


Yet Australia’s federal and state governments have in the past year funnelled A$10.3bn in tax breaks and subsidies to the fossil fuel industry. Almost three quarters of that came in the form of rebates paid to large users of fuel, such as miners and farmers, according to a report published by The Australian Institute, a progressive think-tank. Authorities have also approved an expansion of a Glencore coal mine just north of the Hunter Valley and an extra A$264m in funding for carbon capture storage — a technology that it hopes could extend the life of its coal export industry.

“Australia’s foreign policy for decades has been to undermine other countries’ ambitions to reduce emissions so that we can continue to sell enormous amounts of coal and gas,” says Richard Denniss, chief economist at The Australian Institute. “Australia is not planning a transition away from fossil fuels.

“What we are actually doing is trying to maximise profits in the endgame,” he adds. “That’s why there is a rush to approve new coal mines. We know that in 30 years’ time no one will be buying coal. But if we flood the market and push the price down, we can we can still sell some for the next 15 years.”

‘Money to be made in mining’

Any transition away from fossil fuels will be felt most keenly in places like Maitland, a blue collar city in the Hunter Valley which owes its rich architectural heritage to the profits generated in nearby coal fields.

Four coal-fired power plants in the region are scheduled to close over the next 15 years, as energy companies begin phasing out their most polluting assets. Local coal miners will experience a modest drop in demand as a result of the closures, but of greater concern to the industry are the signs of slowing international demand for Australian thermal coal.

Glencore and BHP, two of the country’s biggest coal producers, reported combined losses of just over $1bn in their Australian coal divisions in the six months to the end of December. In March, the Department of Industry warned that if exporters continued to receive lower prices for their coal due to Australia’s trade spat with China, production levels at higher cost mines could be cut.

“There is so much pressure on coal,” says Gerard Spinks, who has worked in Hunter Valley coal power plants for more than 40 years, “that I think it’s going to disappear off the face of the earth in the not too distant future. It’s inevitable.”

He was one of more than 100 people crammed into a bowling club in a Maitland suburb in March for the inaugural meeting of the Hunter Jobs Alliance, a collaboration of trade unions and environmental groups which wants to help the region prepare for life beyond coal.

Spinks, a trade union delegate at the Bayswater power station, says three generations of his family have worked in the coal business but people now need to be realistic and plan for a future without coal, he says. “We need to get things in place to ensure there is meaningful work in the valley for our kids.”

Several speakers focused on the need for policymakers to grasp opportunities provided by renewable energy, modernise local infrastructure and invest in education. There was also a plea for an end to the bitter acrimony which has divided the community into pro- and anti-coal lobbies over recent years.

“People will still disagree but we need to create a better quality discussion, to find common ground and not yell at one another,” says Warrick Jordan, co-ordinator of the Hunter Jobs Alliance.

Could this year mark a turning point for climate?

Ideological divisions over the future of coal run deep in Australian communities, politics and the media. Malcolm Turnbull, who was ousted as prime minister in 2018 following a failed attempt to reform energy policy, was sacked in April as chair of the New South Wales government’s Net Zero Emissions and Clean Economy Board for proposing a moratorium on coal mine approvals in the Hunter Valley region.

“It’s just thuggery,” says Turnbull, who blamed rightwing media dominated by Rupert Murdoch’s News Corp — for waging a vendetta against him and bullying the government to remove him less than a week after his appointment.

News Corp, which owns almost 60 per cent of Australia’s national and metropolitan newspapers, is a staunch supporter of the government and campaigns against stronger climate action.

“The Murdoch media has spent decades poisoning both our political and literal atmosphere,” Michael Mann, a US climate scientist, told an Australian parliamentary committee on media diversity in April. “The Murdoch press is substantially to blame for serving as a megaphone of climate disinformation. Disinformation that has provided fodder for an activist politician, like former US President Donald Trump, and the current Australian prime minister.”

News Corp rejects this, with Murdoch telling shareholders in November: “We do not deny climate change. We’re not deniers.”

Critics allege the main political parties — Liberal, National and Labor — are addicted to donations from the fossil fuel industry. In the year up to the 2019 general election, political parties received a record A$85m in donations from resource companies — 69 per cent of all monies raised — an analysis of Australian Electoral Commission data by the Grattan Institute think-tank shows.

Bill Shorten, who resigned as leader following Labor’s surprise 2019 defeat, blamed “powerful vested interests” including mining mogul Clive Palmer, who spent more than A$80m on a negative campaign focused on “Shifty Shorten”. Analysts cite the party’s pledge to cut 2030 emissions by 45 per cent when compared with 2005 levels, as a key factor that lost Labor coal mining seats in Queensland.

Labor has since dropped the 2030 target, although it remains committed to achieving net zero emissions by 2050 — a clear point of difference from the ruling coalition. But ahead of a general election, due to be held next year, the party faces internal pressure from MPs in coal regions not to expand its ambition on climate policies or discuss the transition from coal.

“There are excessive progressives in my own party who . . . are trying to change the Labor party, and with some success, from the party of the workers to the party of climate change,” says Joel Fitzgibbon, Labor party MP for the Hunter constituency.

Fitzgibbon, the proud owner of gold cufflinks emblazoned with the letters ‘COAL’, quit Labor’s shadow cabinet in November over its climate change policy. He is agitating for the party to send a clear signal that it supports the industry ahead of a state by-election in the area this month, but critics within Labor say he risks splitting the party.

“Coal power generation is in transition but coal mining is not . . . There is a wealth of money to be made in mining,” he says. “And there is no job in the Hunter that will pay the amount that the miners do . . . semi-skilled miners earn A$120,000 per year as a base rate.”

The need to diversify

Despite the reticence of politicians to discuss transition, local businesses are becoming acutely aware of the need to diversify and are calling for policy changes and funding to help them do so.

At the Port of Newcastle, where bulk carriers shipped 158m tonnes of coal last year to China, Japan and a host of other nations, management is planning a A$2bn investment to build a deepwater container terminal to boost its non-coal revenues by importing everything from grain to consumer goods.

Green says the proposal could transform the port and the state’s economy by reducing costs for businesses, easing traffic congestion in Sydney and creating new jobs in the region. He cites a report by Alphabeta, a consultancy, which forecasts the terminal could provide a A$6bn boost to the local economy and take 750,000 trucks off Sydney roads by 2050. “There are no other deepwater ports on the east coast that can accommodate the ultra large container vessels, so this is a very significant opportunity,” he says.

But the proposal remains blocked by port commitment deeds agreed by the New South Wales government when it privatised Botany, Kembla and Newcastle ports between 2013 and 2014 in transactions that raised A$6.75bn. Under these 50-year deals, the Port of Newcastle would have to pay compensation to the state government if it exceeded a cap of handling more than 30,000 containers a year — rendering its proposed investment uneconomic and limiting Newcastle’s room to diversify.

Australia’s competition regulator is challenging the deeds in court but the state government is refusing to back down, as it could be liable for compensation. “Now is the time for some innovative thinking from both state and federal governments to help this region transition and benefit the wider economy,” says Green.

A ‘technology, not taxes approach’

Under pressure from the EU, which is threatening to impose carbon tariffs on imports from nations that fail to make ambitious emissions cuts, the Australian government — which reduced emissions by just 4 per cent between 2013 and 2021 — has begun to discuss ways to decarbonise the economy. But it has so far refused to introduce a carbon pricing mechanism, which is widely considered the most efficient way to reduce emissions. Instead it wants to rely on new technology to meet its modest target of 26-28 per cent emission cuts by 2030, when compared to 2005 levels.

“We are taking the technology, not taxes approach,” says Keith Pitt, Australia’s mining minister. “There are more than 200 power stations either under construction or being designed and planned right now and they will need to utilise high quality coal and we will look to fulfil that.”

At state government level there are some signs of progress. New South Wales announced a A$25m fund in April — created from mining royalties — to help regions develop new industries beyond coal. It also paid A$100m compensation to Shenhua, the Chinese company, for reversing planning approval for a mine north of the Hunter Valley following community opposition, which thwarted the project.

But neither federal nor state governments plan to impose a moratorium on approving new mines or expansions amid a flurry of proposals by small miners eager to capitalise on the exits made by Rio and BHP. The Australian Institute report detailed 23 applications for new developments with the potential to produce 98m tonnes a year of coal.

“If approved, these mines risk locking large parts of the Hunter in the past,” says Denniss, “while failing to plan for the future.”
