Is Global Warming becoming unstoppable?

Jump to new
Back to the real world.

Another report from the UN raising the issues of multiple tipping points that are threatening the worlds response to the climate crisis. All the issues are raised are life threatening. However I thought it apposite that they chose to highlight uninsurable housing as a major key issue.

The report examines six examples of risk tipping points, including the point when building insurance becomes unavailable or unaffordable. This leaves people without an economic safety net when disasters strike, compounding their difficulties, particularly for the poor and vulnerable.

The climate crisis is increasing the frequency and severity of extreme weather and, for example, a major insurer has already stopped insuring properties in California, due to “rapidly growing catastrophe exposure”, particularly wildfires. Insurance premiums have also soared in Florida, and six insurers in the state have gone bust due to climate-related floods and hurricanes. The report also said half a million Australian homes are estimated to be uninsurable by 2030, primarily due to increasing flood risk.

Another risk tipping point examined in the report is when groundwater aquifers are overexploited to the point that the wells run dry. Aquifers currently prevent half the losses to food production caused by droughts, which are expected to become more frequent due to global heating, the report said.

Analysis also warns of further tipping points on horizon such as drying up of groundwater vital for food supplies

Perhaps we should tell them to have a chat with the Heartland Institute to get reassurance that none of this will ever happen and its all a beat up ?
 

So, what do I do that will change the World's climate Bas?

Perhaps....

Stop understating the reality of what is happening as our climate heats up.

Reconsider your views and publicly recognise we have a very serious problem.

Use your influence in conservative areas of politics to take the urgent actions required to reduce the impact of climate change. This affects everyone

Consider adapting your own lifestyle to a simpler less carbon intensive approach

Prime Minister Anthony Albanese has announced a new pact with the low-lying island country of Tuvalu, allowing residents facing displacement from climate change the ability to resettle in Australia.

Key points:​

  • The deal is the first time Australia has offered residence or citizenship rights due to the threat posed by climate change
  • The US and New Zealand have similar agreements with other Pacific countries
  • Mr Albanese described it as the most significant agreement between Australia and a Pacific island nation ever

Back to Knobbys previous post. A lot pf detail in the analysis on the effect around the world.

The world has experienced its hottest 12 months on record, and El Niño is set to drive temperatures higher​

The world has just experienced its hottest 12-month period in recorded history, with the average global temperature over 1.3 degrees Celsius above pre-industrial levels between November 2022 and October this year.

Analysis of international data, conducted by Climate Central scientists, found that human-induced climate change had significantly elevated temperatures around the world.

The report warned that El Niño was only just beginning to boost temperatures and, based on historical patterns, most of the effect would be felt next year.

While Australia did not experience the same level of extremes compared to many other parts of the world, a hot and dry summer was expected.

Hottest 12 months in probably 125,000 years, with El Niño only just getting started

Between November 2022 and October this year, the average global temperature was more than 1.3 degrees Celsius above pre-industrial levels, and more record highs are on the way.

No amount of information will convince climate science deniers that their beliefs are delusional, poorly informed or just wishful thinking.
So for those who instead like to see how AGW theory is tracking we saw last Friday that for the first time in recorded history the global daily surface air temp was 2 degrees above the IPCC's baseline (aka "reference period").

Somewhat obvious above is the anomaly, which was a crazy 0.5 degrees higher than the previous record high for the same period.
This does not bode well.
 
2023 absolutely shatters all previous records doesn't it ? Maybe .

Clearly there has to be some other spin on these figures. Or perhaps they will be simply ignored ?
 
Hey @basilio a heads up, people have a lot more issues to worry about than global warming, living in a car is a lot closer than the sea lapping up against it.
It's nice your keeping everyone abreast of what they can't change, while they are dealing with a crisis at their front door.

By the way have you put solar on the roof, had the home battery installed and bought the EV yet?
You hadn't been in a situation to afford that last time I asked.

You reduce your carbon footprint FFS, you go to one household T.V, one computer which should be low consumption state of the art, heat pump hot water, maximum solar generation for you house ( 6.6KW for single phase, 10KwW for 3 phase), install a solar battery and buy an electric vehicle, like Bas.
Otherwise you do your best with what you've got and the money you have and stop trying to tell everyone else what they should be doing.
Otherwise your a DICK.
 
Yep we (me) can all do our bit to reducing our carbon footprint. And as I have said repeatedly I have taken many of the steps to reduce my footprint. But I still have (and want to keep) a wife who lives 3 degrees warmer than me and cannot accept some of the strictures one might like to do to reduce our energy use.

Addressing global warming by drastically reducing GG is a whole of society issue. But realistically it has to start with an acknowledgment we have a serious problem that requires massive action across all of society. Effectively a mass mobilisation approach.

Unfortunately ASF as a representative microcosm of the world highlights how difficult that approach will be given given the refusal of many people to see there is a problem or that they(we) should do anything about it. What really irks me though is the denigration of renewable energy as part of a potential solution when on economic grounds it is clearly streets ahead of coal. gas and nuclear power.

Where are we know ? How could the story have been different ? These two articles explore those questions.

Build a massive waterside mansion, buy a private jet... and a 400 ft yacht, when not in the air or on the water, drive around in motorcades, and lecture the plebeians on their carbon footprint....

... collect environmental awards with above modes of transport.
 
And of course, all of this will be while living in a tax haven

Renewable energy absolutely can work both technically and economically.

What frustrates, and that's putting it lightly, those at the proverbial coalface of getting it done is the denial of the scale of what's required.

Electricity % of Total Final Energy Consumption (TFEC) by state 2021-22 (Australian Government data):

Tasmania = 41.3%
NSW = 26.1%
SA = 22.5%
Queensland = 20.3%
Victoria = 20.3%
NT = 15.9%
WA = 15.5%

Firstly there's a need to electrify everything that can be electrified at the point of use. Out with gas, petrol and so on and in with electric this, electric that and electric something else.

Secondly drop the politics and get on and build what's needed on the supply side. Just build it - don't listen to the anti-everything brigade who'll bog down every single project with their nonsense claims. Just take a proper scientific approach and make things happen.

In relation to that politics, bury the past and that goes for all sides because there's been more than enough BS from everyone from the Left to the Right. Drop the lot, toss it in the bin where it belongs, and start afresh on that with a strictly scientific approach overseen by a board who are appointed based strictly on merit.
 
The issue of lethal humidity is raised again as Rio De Janeiro suffers a record breaking heat wave.

Humidity during Brazilian heatwave made tragic Taylor Swift concert temperature feel like 59C​

"Absurdly" high temperatures in Brazil have prompted experts to warn of the "severely underestimated" dangers of humidity after a young woman fainted and died during a Taylor Swift concert.

Key points:​

  • Human health and climate experts say humidity compounds the danger of extreme heat
  • A Brazilian meteorological service said the country's heatwave could be like no other
  • Australians could face similar risks, according a heatwave expert, including in areas with milder overall temperatures

Temperatures in parts of Rio de Janeiro, where Swift's Eras concert was held, soared as high as 42 degrees Celsius on Friday, according to Meteologix.

But when humidity was factored in, the heat index – similar to Australia's "feels like" temperature – showed a reading of almost 60C.
"Those temperatures are really extreme," University of New South Wales climate scientist Sarah Perkins-Kirkpatrick said.

"It takes a really high temperature with a combination of humidity to reach the apparent temperature of 59.3C.

The heat was brutal at Taylor Swift's tragic Rio concert. One factor made it even more dangerous

The heat index – or "feels like" – temperature reportedly reached 59C in Rio de Janeiro as thousands of fans queued up for Taylor Swift's performance.

On the subject of climate the 'Ozone Hole' has popped up its head yet again.

World proven wrong as 'shock' discovery made about ozone layer

Four decades after a major global change was enacted, new research has cast doubt on what it really meant for our planet.
au.news.yahoo.com
From the article:
Back in the 1980s, everything was getting bigger, the hole in the ozone layer.
This hole was causing Antarctica to melt at an alarming rate, but then the world came together and fixed the problem by banning CFC spray cans, right? Well, not quite.

New research out of New Zealand has revealed the hole might not be recovering and worse still, it might be expanding. The findings have even shocked the study’s lead author Hannah Kessenich from the University of Otago who described it as “remarkably large”.

“When I began my work in 2021, I expected, like many of us, that the ozone hole was healing,” she told Yahoo News Australia.

What you need to know about the ozone hole​

  • The 1987 Montreal Protocol was a global agreement to ban the production of CFCs
  • The core of the ozone hole has reduced by 26 per cent since 2004 during the spring months
  • Previously reported recovery of the hole during spring is now in question
  • The hole is around 26 million square kilometres in size

Kessenich concedes that scientists “still have a lot of work to do” in understanding the complex mechanisms that are contributing to the hole’s condition. But the changes could be linked to changes in the atmospheric layer above the ozone layer.

“There’s more to learn. But likely we won’t see the hole get too much worse. And there is variation from year to year,” she said.
 
The International Energy Agency says world demand for coal rose by 1.4 per cent in 2023, surpassing 8.5 billion tonnes for the first time on record.
 
A wrap up of how the warmest year on human record (by a record margin) impacted the climate and environment.


How 2023’s record heat worsened droughts, floods and bushfires around the world ​

2023 was a year of record-breaking heat, devastating storms and floods, deepening droughts and raging wildfires. These events showed how climate change is affecting the global water cycle and our livelihoods.

Our international team of researchers today released a report, the Global Water Monitor, documenting the impact of the record heat in 2023 on the water cycle. We used data from thousands of ground stations and satellites to provide real-time information on various environmental parameters.

The report summarises conditions and events in 2023 and long-term trends. We found global warming is profoundly changing the water cycle. As a result, we are seeing more rapid and severe droughts as well as more severe storms and flood events.
Scores of countries had record average annual temperatures in 2023. Severe droughts hit three continents. The world’s largest forests suffered, with Canada battling huge fires and the Amazon hit hard by drought.

How 2023's record heat worsened droughts, floods and bushfires around the world

The impacts of record heat on the global water cycle were severe and wide-ranging – and the trend will continue in 2024.
