Is Global Warming becoming unstoppable?

An absolute certainty of global warming is a marked increase in sea levels as glaciers melt, oceans warm and expand and the ice mountains at the Poles recede. Where does that take the world community ? What will happen to Australian coastal communities ? Which coastal towns will become uninsurable ?

Rising seas threaten ‘mass exodus on a biblical scale’, UN chief warns​

António Guterres calls for urgent action as climate-driven rise brings ‘torrent of trouble’ to almost a billion people

An increase in the pace at which sea levels are rising threatens “a mass exodus of entire populations on a biblical scale”, the UN secretary general has warned.

The climate crisis is causing sea levels to rise faster than for 3,000 years, bringing a “torrent of trouble” to almost a billion people, from London to Los Angeles and Bangkok to Buenos Aires, António Guterres said on Tuesday. Some nations could cease to exist, drowned under the waves, he said.

Addressing the UN security council, Guterres said slashing carbon emissions, addressing problems such as poverty that worsen the impact of the rising seas on communities and developing new international laws to protect those made homeless – and even stateless – were all needed. He said sea level rise was a threat-multiplier which, by damaging lives, economies and infrastructure, had “dramatic implications” for global peace and security.

......A new compilation of data from the World Meteorological Organization (WMO) shows that sea levels are rising fast and the global ocean has warmed faster over the past century than at any time in the past 11,000 years. Sea levels rise as warmer water expands and ice caps and glaciers melt.

Guterres said: “Even if global heating is miraculously limited to 1.5C, there will still be a sizeable sea level rise.” A sea level rise of about 50cm by 2100 is likely, but the WMO said there would be a 2-3 metre rise over the next 2,000 years if heating were limited to 1.5C, and 2-6m if it were limited to 2C. A UN report in October said there was “no credible pathway to 1.5C in place”. Current national targets, if met, would mean a 2.4C rise in temperature.

This report is exceptionally good news on the decarbonisation front for many reasons
1) A number of major Australian industries have backed the report. They find it credible and doable.
2) The reduction CO2 emissions is spectacular. More than 90%
3) The cost is significant but in the context of big business capital programs quite reasonable.

Looks as if Twiggy was on the money with his decision to make FMG a leader in decarbonising its operations.

Australia’s big emitters could cut CO2 by 90% by 2050 without offsets, report finds​

Report finds that supply chains for major industries, including iron and steel, could cut annual CO2 to 17m tonnes by mid-century

Some of Australia’s largest heavy industrial companies have backed a report that says they could cut direct greenhouse gas emissions in their supply chains by more than 90% by 2050, and not have to rely heavily on carbon offsets.

The report, by the Australian Industry Energy Transitions Initiative (ETI), prepared over three years by Climateworks Centre and the CSIRO, found the industrial transition would cost the equivalent of $21bn a year over three decades if Australia were to play its part in trying to limit global heating to 1.5C.

.....The report, Pathways to industrial decarbonisation, looked at five major supply chains for industries – including iron, steel, aluminium, chemicals and liquified natural gas (LNG). It found they could cut annual CO2 from 221m tonnes in 2020 to 17m tonnes by mid-century while steel and iron production rose by nearly 20% and aluminium production by more than 30%.

Anna Skarbek, the chief executive of the Climateworks Centre, based at Monash University, said about two-thirds of the estimated required – equivalent to $20.8bn a year over a 30-year period – was needed in the energy system as it shifted to renewable sources, the rest in technology for industrial, electrification and energy efficiency.

While large, she said the investment was equivalent to just a tenth of the $236bn a year export value of the five supply chains examined and was comparable to other major investments.

The industry initiative worked with companies responsible for about a fifth of the country’s industrial CO2 and a third of the market value of the ASX100. Its report included supporting statements from the Australian Industry Group, BHP, Orica, Rio Tinto and some major banks and super funds.

“We definitely have to rethink. If you look at the way the valley’s shaped, that’s where water has been – so it’s not the first time.”

Rebuild? In Napier? Hmmmm...How about no. NZ has 0% chance of impacting or changing global climate and 100% chance of impacting or changing building locations and standards. There's a reason we don't often see mansions under water. They only develop these areas for poorer people. It was going to flood eventually with or without global warming. Plenty of areas of high ground to settle. Leave the low areas for parks and crops.

Auckland is very different, but no surprise the lowest parts are the poorest parts.

I got my House insurance renewal today. I'm certainly not in a fire or flood area. The premiums jumped from $1076 to $1896.

That's CC driven floods and fires for you. I'm sure almost everyone has a similar story - except for those who can't get any insurance or have a bill 10 times last year.

This is how it is affecting the people destroyed by repeated flooding in Lismore.

Before the floods I thought climate change wasn’t my problem. Now, I’m not waiting for someone else to fix it ​

Honestly Sean we have little to worry about with climate change.
Plenty of other more immediate issues to (not) worry about.

I suppose if we can ignore CC we can do the same for them ? Call them Acts of God ?

Well considering that the atheist left has substituted government for God, I guess we can deem the coming nuclear winter as an act of God?

I'm in both camps on this one.

On one hand I've done my best to understand the science. I've read plenty from credible sources and I've gone as far as to conduct my own experiments which, whilst subject to various limitations, did produce results in line with the theory.

I've also gone down the track of seriously examining, in detail, how we could put an end to the use of fossil fuels and I've been a relatively early adopter of "green" practices personally.

But on the other hand I'll call out hypocrisy when I see it and the mainstream environmental movement has that in abundance.

To be blunt - with present and near term technology there's no chance we're fixing this without rather a lot of hydro megaprojects and nuclear. It's as simple as that. Wind and solar have a big role to play, to lesser but significant extent so do things like geothermal and tidal, but the world isn't getting off fossil fuels anytime soon without a hefty contribution from hydro and nuclear.

Now go and find me an environmental activist group or political party that's even remotely keen on big dams or reactors. Heck most aren't even that keen on transmission lines crossing the landscape.

Then there's population. The elephant in the room of so many problems very few are willing to acknowledge.

So it all seems like whingeing. A lot of screaming that we must take action but baulking at going through with it. Build some wind and solar OK but that's it, anyone who suggests we go all the way and actually get off fossils won't be tolerated even slightly.

It's all a bit like the person who complains they're single and haven't been on a date in years. Trouble is, they find some reason to reject literally every potential partner they come across and in the unlikely event they do go on a date, the other person will seriously regret it if they dare try and take it any further. Twenty years later, they're still single and still complaining they can't find anyone meanwhile everyone else has got on with life.

In saying that well I'm no fan of nuclear as a concept and I'm not keen on "dam the lot" approaches either but I definitely do accept reality. There are certainly examples of places that have no need for nuclear power in the grid (Australia and NZ being among them) and there are certainly rivers that from a rational ecological perspective, on a scientific basis not a political one, really shouldn't be sent through a headrace and down a penstock. Overall though, we're not going to fix this without both technologies being applied on a greater scale than they are at present so the default answer to such things, unless there's a legitimate problem with a specific project, needs to be yes.

Noting that at a technical level the two are largely alternatives to each other. That is, nuclear for constant operation or hydro for storage and deep firming of other renewables (wind and solar). Both can be used in the same system but they're alternatives as such noting that in some places it's far more practical to use one than the other hence, at the global level, both are needed. What's not an option is to have neither - do that and then it's fossil fuels either outright or to firm renewables.

Former ADF chief calls for release of secret report into security threat posed by climate crisis​

Chris Barrie says global heating poses larger security threat than China, and Australians should be armed with this information

A former Australian defence force chief has called on the government to release its assessment of the security threats posed by the climate crisis, which he says they received late last year.
Guardian Australia understands the Office of National Intelligence’s “urgent climate risk assessment” looked at how global heating affected Australia’s national security, but relied in part on classified information.

This means the government would have to decide whether, and how, the assessment is released publicly.

The former ADF chief Chris Barrie said he was concerned climate security risks were “missing in action” in the public debate triggered by the Aukus nuclear-powered submarine announcement.

Barrie said it was “rather surprising” that the Albanese government was continuing the previous Morrison government’s framing of China as the predominate security threat to Australia.

“Climate change as a security threat seems to be totally overlooked,” he said.

The lose of ice world wide is a serious issue the article below lays bare just how bad it is

"The rhythmic expansion and contraction of Antarctic sea ice is like a heartbeat."

But lately, there’s been a skip in the beat. During each of the last two summers, the ice around Antarctica has retreated farther than ever before.

And just as a change in our heartbeat affects our whole body, a change to sea ice around Antarctica affects the whole world.

Today, researchers at the Australian Antarctic Program Partnership (AAPP) and the Australian Centre for Excellence in Antarctic Science (ACEAS) have joined forces to release a science briefing for policy makers, On Thin Ice.

We’ve been able to measure sea ice from satellites since the late 1970s. In that time we’ve seen a regular cycle of freezing and melting. At the winter maximum, sea ice covers an area more than twice the size of Australia (roughly 20 million square kilometres), and during summer it retreats to cover less than a fifth of that area (about 3 million square km).

In 2022 the summer minimum was less than 2 million square km for the first time since satellite records began. This summer, the minimum was even lower – just 1.7 million square km.

Antarctica’s heart of ice has skipped a beat. Time to take our medicine

It may or may not have similar effects such as occasional artic winds flowing over the continent or maybe more rain or what about encouraging La Nina over El Nino?
