Is Global Warming becoming unstoppable?

Rederob the examples you gave of attempting to geo engineer the climate and the problems and costs associated are fair comment, However did you read the particular technology I quoted ? Looks promising, clever and cost effective.

And if it can reverse the current record melting of Arctic sea ice ... that would be invaluable

Bas, it was included under the point about increasing surface reflectivity, but I did not propose "beads".
The problem with the Arctic will be that beads cannot subvert ice decreases because ocean heat transfers will be too powerful. And that would be aside from unintended environmental consequences, and the massive cost.
Geogineering has no silver bullets, but there may be some cheap technological advances in future which can act in tandem with reducing CO2 emissions.

The inevitability of Global heating and it's consequences are emerging everywhere - and at the same time.
This story is going to be repeated many times.

Port Fairy's decades-long push for wall to stop seaside tip spewing rubbish into the ocean to rise from the waves

Decades of rubbish, faeces, asbestos and medical waste is at risk of spilling into the Southern Ocean if a million-dollar rock wall in south-west Victoria is not built in time.
Key points:

• The rubbish tip dating from the 1970s was originally 100 metres inland, but erosion has brought it to within coastal dunes
• Council has approved the construction of a $1.1 million rock wall, but admits it is a stop-gap measure
• Of nearly 600 landfill sites in Victoria, approximately 43 are located on the coast

The seaside community of Port Fairy has been petitioning the Moyne Shire Council for more than a decade to have rubbish from two decommissioned landfill sites, buried within coastal dunes, properly removed.

The landfill sites were closed in 1998, but coastal erosion over the past 21 years has thinned the sand between beach and rubbish.

By council's own estimates, one strong storm surge could spill waste dating back to the 1970s onto the beach and into the ocean.

"It's a problem that's not going away and we don't want to hand it on to another generation or council in five-to-10 years," said Moyne Shire Mayor Mick Wolfe.

Quite right Sdajii. In 30 years the economy will be ruined by rising sea levels that flood London not to mention hundreds of klms of other other seaside areas. So they can deal with a few million internal climate refugees as well as the millions pouring in from Africa and Spain.

Depends totally on what else they also do (or don't do).

Exactly. I wonder if anyone has asked them the cost of this policy liked they asked our Labor Party.

The truth is no one knows the answer to that question because there are so many variables involved.

If anyone really believes we will last another 30 years you are really in fairy land.

Britain has been on the renewables path for a very long time and is ahead of most nations around the world. So if there has been a cost, then it's been very well absorbed to date as the UK certainly has not been and industrial backwater fraught with economic woes.
The elephant in their parliament is BREXIT.

Drastic shift in city lifestyles urged to avert climate crisis
by Megan Rowling | @meganrowling | Thomson Reuters Foundation

By Megan Rowling

BARCELONA, June 12 (Thomson Reuters Foundation) - You bound out of bed in your wood-framed eco-home, throw on a rented dress, jump on an electric bike and head to the "tool library" to borrow a trowel to plant your vegetable patch.

This is the kind of lifestyle urban dwellers need to adopt in just a decade's time to play their part in keeping global warming to a relatively safe 1.5 degrees Celsius (2.7F) above pre-industrial levels, the C40 cities network said on Wednesday.

"Everything and everyone will have to change," said Mark Watts, executive director of C40 - nearly 100 big cities acting on climate change.

"But the first step is understanding what needs to be done."

The 2015 Paris Agreement set a goal to limit average global temperature rise to "well below" 2 degrees Celsius (3.6F), and to "pursue efforts" for 1.5C. But emissions are currently on track to fuel at least 3C of warming, climate scientists say.

The C40 study by London-based engineering firm Arup and Britain's University of Leeds measured the carbon footprint of urban areas in a new way to include what businesses and citizens use, eat and wear, and how those items are made and transported.

Up to now, cities have focused on curbing emissions from buildings, energy, transport and waste produced locally.

But 85% of emissions associated with the goods and services consumed in C40 cities are created elsewhere in the world and need to be addressed as well, the network noted.

Cities need to at least halve their emissions - already 10% of the global total - by 2030 to have a chance of keeping global warming to 1.5°C, it said, by transforming their use of food, clothing, electronics, transport and building methods.

Urbanites would need to cut their annual meat consumption to 16 kg per person from an average of 58 kg now, the study said.

And fast-fashion would have to be ditched, with clothing business models focused on recycling, upgrading and renting so people would only buy three new items each year.

Watts told the Thomson Reuters Foundation some C40 mayors turned "slightly pale" when they learned of the drastic changes required, but recognised the analysis "helps them do their job".

Yep and the USA see's it as a chance for shorter shipping routes, more oil and gas to be exploited.

Meanwhile the recent Aussie based report, about realistic 3-4 degrees by 2100 is sobering. Not sure even the worst case of 6-8 degrees is out of the realistic measure by then.

Thankfully, I doubt I will be around in 2100. Pre 2050, given some disturbing numbers on every measure coming out from Temp to CO2 and CH4 or Methane .... being somewhat disturbed the 50 cm sea rise by 2100 is now 75 cm if not 100 cm .... makes me wonder is the USA just stupid ?

Spending 500 million on pumps to keep Miami dry in 2019 from high tides is a loosing game ...

Yes we will adapt, possibly move, but when 50% of arable land is no longer of any use verses a population 150% of 2000 levels at say 9 billion, its going to be fun.

Must be positive and realistic. Not give time to nutters who are either extreme and deny any issue one side or even that CO2 is an issue or the other flip side that its going to end next week.

Impacts profound ones post 2050 and more post 2100. Can we adapt ? Can we even if we tried ?

At this stage melting of the Permafrost and frozen methane is a given post 2050. Adding 200 PPM to the CO2 level and casting in concrete a 3 degree plus 2100 rise. Amazon having droughts at 2.5 degree rise and sea going 100 cm assured I suppose.

Its when the bloody Antarctic ice melts that we are talking 5 metre sea level rises and well .... London will be awash at 1 metre either ways as well as the lower end of NY. Miami ... New Orleans and so so many other nations. About 100 million refugees by 2050 and a billion by 2100. Climate flood followed by drought then wild storms likely case massive crop fails in large nations and so on ...

happy happy happy .... USA I do dislike them at the moment.

Came across these reports in the last few days while doing some research on CC adaptation. Very challenging stuff..

Prof. Jean Palutikof founding Director of the National Climate Change Adaptation Research Facility (NCCARF) at Griffith University, provides a graphic picture. Professor Palutikof was based at the UK Met Office during which time she managed the production of the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report for Working Group II (Impacts, Adaptation and Vulnerability). Professor Palutikof is among the foremost scholars of climate change adaptation and was lead author and review editor for several assessments of the IPCC.

They are a long way down the renewables path, but they obviously have a way to go and don't think wind is going to manage it.

 

[sptrawler]

The truth is no one knows the answer to that question because there are so many variables involved.

Well the cost of Hinkley Point C nuclear power station, I think I read is $26billion and that is for a station capable of supplying 7% of the system load. So it isn't cheap.
Also:
The UK Government's energy national policy statement in June 2011 confirmed that eight sites are suitable for new nuclear power stations by 2025 – all are the sites of existing nuclear plant. Developers are currently planning new build at six of the sites (see map). The other nominated sites are Heysham and Hartlepool.

Country towns close to reaching 'day zero', as water supplies dry up in the drought

Across New South Wales and Queensland's southern downs, country towns are approaching their own 'day zero', as water supplies dry up in the drought.

Key points:

• Water security is still almost non-existent for many rural communities, with 10 towns at risk of running dry in six months
• Locals in Tenterfield are not washing cars or watering gardens and are cutting back on showers
• Even in high rainfall areas like Walcha, locals are enduring constant water restrictions

Ten towns, including major centres, are considered to be at high risk of running out within six months, if it doesn't rain and if water infrastructure isn't improved.

Councils are rushing to put emergency measures in place, but more than a decade since the end of the millennium drought, water security is still almost non-existent for many rural communities.

Yes, there will be a day of reckoning.

Then some rain will come and people will go back to their current unsustainable practices as if nothing ever happened. Over-clearing, over grazing, stealing water, then putting their hands out to the taxpayers and all the other stuff they have been doing for centuries.

Former fire chiefs warn of more catastrophic weather events
We often get alarming warning messages from our emergency services, but this one about the “escalating crisis” they face is coming from the very top.

Stephanie Bedo@stephanie_bedo

news.com.auApril 10, 201910:59am
When a group of experts with more than 600 years of combined experience get together, it’s probably time to listen.
But the message these 23 former fire and emergency chiefs have for Australia is rather alarming.
They have seen “how Australia is experiencing increasingly catastrophic extreme weather events that are putting lives, properties and livelihoods at greater risk and overwhelming our
emergency services”.
The driver? Climate change.
