Is Global Warming becoming unstoppable?

Interesting article showing the complexity that exists between ideology and reality, everyone wants to be 'clean', but suffering the pain seems to be a stumbling block.
From the article:
When Indonesia agreed last year to clean up its energy system with an estimated $20 billion of help from a coalition of wealthy countries and large financial institutions, world leaders hailed the deal as “extraordinary,” “realistic,” and “historically large.”

Almost 10 months later, as Southeast Asian leaders gather in Jakarta, the hosts have little to show off. A much-anticipated investment blueprint has been postponed. Parties have yet to agree on governance, baseline data or the funding required to curb greenhouse emissions and wean the world’s largest coal exporter off fossil fuels. The most ambitious of the Just Energy Transition Partnerships—the international finance projects designed to cut climate-warming emissions—is faltering.

One especially thorny issue is that Indonesia’s coal-dependency is greater and more complex than all sides initially acknowledged. A 362-page draft document reviewed by Bloomberg spotlights the rapid growth of a fleet of dedicated, “captive” coal-fired plants powering industrial expansion but not connected to the grid. Incomplete data, especially on new and planned facilities, means even the exact scale of the problem is unclear.
Indonesia is the biggest emitter in Southeast Asia by a long shot, thanks to vast coal reserves and a power-station construction boom over the past decade or so. But its regional neighbors and other emerging economies also depend on coal-fired plants that will need to be retired to prevent the worst consequences of global warming. Vietnam is advancing with its own JETP. Senegal struck a deal in June.

The initial promise of peaking Indonesia’s power sector emissions by 2030 at no more than 290 million tons of carbon dioxide, about 20% below a baseline level for the year, looks out of the question. An alternate scenario laid out in the draft plan would raise the target maximum to 395 MT of CO2, to account for the construction of new captive plants to serve growing industrial power needs.
Then there is the question of the emissions target agreed last year. People close to those discussions say negotiators sidestepped the impact of Indonesia’s growing fleet of captive coal-fired power plants, single-purpose engines built to support nickel production and other heavy industry in places the grid doesn’t reach. At best, the issue was dramatically underestimated, which may explain why the original deal included a loophole for new captive coal plants.
According to the draft, current captive capacity is around 13 gigawatts with another 21.5 in the pipeline, and almost half of that is already under construction. That is higher than previous assumptions—Indonesia’s total coal-power fleet is usually pegged at roughly 40 GW, so captive accounts for about a third—and points to a rate of growth at odds with the need to eliminate coal entirely by mid-century to hit global climate commitments.

Worse, the lack of centralized data casts doubt even on the new figures and makes credible estimates for a clean-up impossible. There are questions around the age, size and function of captive coal plants, which are not part of the numbers published by the state utility and where few parties involved have incentives to be transparent.

"Good" story. Not in a good way obviously.

The "captive" coal plants running industrial infrastructure is a real worry. There already a sunk cost in the construction. I imagine, perhaps , the coal required is cheap and perhaps even onsite ?
In "theory" an extensive solar/wind array with back up batteries could replace them. Seems doable in Australia but clearly the climate and geography are very different.
Be interesting to see what practical technical options would be available to provide the clean energy for these plants.

This analysis of the issue offers further insight. It is a wicked problem like so many in this field. :(

 
The Transition Zero website is a business based model which pulls together the metrics of movingfro9m coal to renewable energy production particularly in Third World countries.

Worth checking out for engineers.

First and foremost option an engineer will suggest can be summed up in one word. Grid. Extend it to where it needs to be.

Isolated power systems aren't that uncommon indeed we have a number of them in Australia at present:

Numerous small systems serving an outback town, island or mine from a single generation source.

By far the largest system not on the main grid being the South-West Interconnected System (WA) which serves the south-west of the state including Perth. In the WA context it is the main grid, only in the national context is it a "remote" system.

Also in WA the North-West Interconnected System (NWIS) is completely separate from the SWIS. Generation is primarily sourced from various natural gas-fired power stations. Diesel has also been used intermittently for additional capacity.

Other notable standalone systems in various states not on a main grid:

North-eastern WA from Wyndam to Kununurra and south. Generation is primarily hydro and the rest diesel.

Mount Keith - Leinster (WA) with generation from two gas-fired stations.

Alice Springs (NT) with generation from two gas-fired stations (diesel as backup fuel)

Tenant Creek (NT) with generation from gas (diesel as backup fuel).

Darwin - Katherine Interconnected system (NT) is the "main" power system in the NT. Generation primarily from several gas-fired stations (diesel as backup fuel).

North West Power System (Qld) not to be confused with the NWIS in WA supplies Mt Isa and the surrounding area with gas being the generation source.

If we go back in time then we had a lot more standalone systems:

Victoria and NSW were the first two states interconnected in 1959.

SA connected to Victoria in 1990.

Queensland connected to NSW in 2000 at limited capacity and more substantially in 2001.

Tasmania first physically connected in December 2005 with extensive testing commenced at that time - a single DC connection and it was the longest such system in the world when built hence the testing was quite substantial. Official opening was April 2006.

So the idea of a single large power system is relatively recent. At this point the next planned step is to connect the Northern Power System to the rest of Queensland and thus the "national" grid.

In any other country the same applies. Wherever practical, extending the grid is usually a winner in terms of enabling the use of alternative energy sources.

Key issue there is economics. If we're talking about a small fishing village or something like that then it doesn't really matter and it works to use wind / solar with diesel as backup but if we're talking about serious heavy industry then price and reliability is crucial. In that case the grid wins due to scale - diversity of demand itself brings benefits as does the access to geographically diverse wind / solar generation and location-critical sources such as hydro or geothermal, or a great big nuclear facility if someone builds one.

Put them on the grid if possible. :2twocents

By all means we should be improving the insulation of buildings, indeed we ought be improving construction standards more generally as well, but the idea of sending people to prison, actual real prison, for having the wrong boiler at home is taking things way too far:



Watch to the end - they actually agree on common sense measures, it's the political BS that's the problem.

‘We’re not doomed yet’: climate scientist Michael Mann on our last chance to save human civilisation

The renowned US scientist’s new book examines 4bn years of climate history to conclude we are in a ‘fragile moment’ but there is still time to act

“We haven’t yet exceeded the bounds of viable human civilisation, but we’re getting close,” says Prof Michael Mann. “If we keep going [with carbon emissions], then all bets are off.”

The climate crisis, already bringing devastating extreme weather around the world, has delivered a “fragile moment”, says the eminent climate scientist and communicator in his latest book, titled Our Fragile Moment. Taming the climate crisis still remains possible, but faces huge political obstacles, he says.

....One motivation for the book, Mann says, is the rise of climate doomism: “We haven’t seen an end to climate denial, but it’s just not plausible any more because people can see and feel that this is happening. So polluters have turned to other tactics and, ironically, one of them has been doomism. If they can convince us it’s too late to do anything, then why do so?”

Mann says he had noticed how climate history was being weaponised by doomers. “This idea that these past mass extinction events translate to ensured mass extinction today because of, for example, runaway methane-driven warming [as permafrost thaws] isn’t true – the science doesn’t support that.”

1.5C is already really bad but 3C is potentially civilisation-ending bad.

Our climate fate hangs in the balance, Mann says: “There’s fairly compelling evidence from the past, combined with the information from climate models, that if we can keep warming below 1.5C then we can preserve this fragile moment. But if we go beyond 3C, it’s likely we can’t. In between is where we’re rolling the dice.” Today’s climate policies and action would lead to about 2.75C, while delivering all the pledges and targets set to date would mean 2C.

“So it’s a question of how bad we’re willing to let it get,” he says. “1.5C is already really bad but 3C is potentially civilisation-ending bad.”
 
I always find "Just have a think" offers excellent analysis on all of its research. Sober, detailed, scrupulous.

So whats happening in Antarctica ? Check it out.

 
Do Governments, Public Services, Businesses, People in general actually want clear, factual information about what is happening to the environment as global heating gathers force ? Do we want to be told what the near future brings us given the path we are taking ?

Or do we prefer studied ignorance ? Some purposely general "concerns" with some promising fairy dust thrown to make the sandwich (politically) palatable. And then throw any blame on someone else ?

I know from experience how many scientists have been gagged or had their work watered down. This story highlights that situation.

Gagged and grief stricken, but not without hope

The beauty and wonder of the natural world is what keeps these scientists fighting to protect it. But a culture of suppression and self-censorship has meant that speaking out comes at a cost.

 
Latest information of West Antarctica research. I wonder which coastal cities will have to be abandoned ?

Rapid ice melt in west Antarctica now inevitable, research shows

Sea level will be driven up no matter how much carbon emissions are cut, putting coastal cities in danger

Accelerated ice melt in west Antarctica is inevitable for the rest of the century no matter how much carbon emissions are cut, research indicates. The implications for sea level rise are “dire”, scientists say, and mean some coastal cities may have to be abandoned.

The ice sheet of west Antarctica would push up the oceans by 5 metres if lost completely. Previous studies have suggested it is doomed to collapse over the course of centuries, but the new study shows that even drastic emissions cuts in the coming decades will not slow the melting.

The analysis shows the rate of melting of the floating ice shelves in the Amundsen Sea will be three times faster this century compared with the previous century, even if the world meets the most ambitious Paris agreement target of keeping global heating below 1.5C above pre-industrial levels.

 
Could quickly could ice melt in Antarctica? Potentially very, very quickly.:(

Bit lacking in predictions.

I will be paying very close attention this coming summer.

I am hoping that this year was an outlier and things will stabilise however if it doesn't the implications for coastal cities is enormous.

Particularly in say Elwood of Melbourne, I am sure nearly every major Australian city except Canberra would have major concerns.

Yellow is 20mASL (metres above sea level) and higher.

The 20m being just an arbitrary number I picked.

So overall our cities do have quite a bit of land close to sea level. And of course it's not just a question of whether your house is on higher ground, there's also the question of the road leading to it.

Quick read​

  • In short: New research has found Antarctic sea ice levels appear to be changing, with lower levels becoming the new normal.
  • Scientists say warming ocean temperatures are having an impact that will be a "struggle to recover from".
  • There is currently 1.5 million square kilometres less Antarctic sea ice than typically seen at this time of the year.
  • What's next? Climate scientists are calling for an urgent reduction in fossil fuel emissions.
Climate change is fundamentally changing Antarctic sea ice patterns in ways which may not be possible to reverse, Antarctic scientists have warned.

The dire message comes through new research which shows evidence of Antarctic sea ice levels being pushed into a new state of diminished ocean coverage — with more "record lows", like observed earlier this year, expected.

Report lead author Ariaan Purich, a climate scientist with Monash University's Securing Antarctica's Environmental Future team, said the results were cause for alarm.

"As part of this study, we were wanting to confirm this hypothesis… that we're in a new low state ," Dr Purich said.
"Sea ice isn't behaving in the way we previously expected [it] to."

 
The big picture. How is global heating affecting the broad range of liveability factors around the world.

One of the issues many people overlook is that liveability doesn't mean things are unbearable all the time. A series of short term extreme weather conditions can create a situation that causes catastrophic outcomes which won't be reversed when the weather calms down.

Earth’s ‘vital signs’ worse than at any time in human history, scientists warn

Life on planet is in peril, say climate experts, as they call for a rapid and just transition to a sustainable future

Earth’s “vital signs” are worse than at any time in human history, an international team of scientists has warned, meaning life on the planet is in peril.

Their report found that 20 of the 35 planetary vital signs they use to track the climate crisis are at record extremes. As well as greenhouse gas emissions, global temperature and sea level rise, the indicators also include human and livestock population numbers.

Many climate records were broken by enormous margins in 2023, including global air temperature, ocean temperature and Antarctic sea ice extent, the researchers said. The highest monthly surface temperature ever recorded was in July and was probably the hottest the planet has been in 100,000 years.

The scientists also highlighted an extraordinary wildfire season in Canada that produced unprecedented carbon dioxide emissions. These totalled 1bn tonnes of CO2, equivalent to the entire annual output of Japan, the world’s fifth biggest polluter. They said the huge area burned could indicate a tipping point into a new fire regime.


 
In the spirit of balance and before anyone becomes too depressed we should check out the counterview about global heating.

  1. There cannot be a climate crisis when temperatures are unusually cool.
  • Scientists have documented, and even the United Nations Intergovernmental Panel on Climate Change has admitted, that temperatures were warmer than today throughout most of the time period that human civilization has existed.
  • Temperatures would have to keep warming at their present pace for at least another century or two before we reach temperatures that were common during early human civilization.
  • There can be no climate crisis – based on the notion of dangerously high temperatures – when humans have thrived in temperatures much warmer than today for most of the last 12,000 years.
