How can we convince the greedy corrupt of our existential reality?...


World’s top climate scientists expect global heating to blast past 1.5C target

Exclusive: Planet is headed for at least 2.5C of heating with disastrous results for humanity, poll of hundreds of scientists finds

Hundreds of the world’s leading climate scientists expect global temperatures to rise to at least 2.5C (4.5F) above preindustrial levels this century, blasting past internationally agreed targets and causing catastrophic consequences for humanity and the planet...

Almost 80% of the respondents, all from the authoritative Intergovernmental Panel on Climate Change (IPCC), foresee at least 2.5C of global heating, while almost half anticipate at least 3C (5.4F). Only 6% thought the internationally agreed 1.5C (2.7F) limit would be met.

Many of the scientists envisage a “semi-dystopian” future, with famines, conflicts and [climate forced] mass migration...


We asked top climate scientists what they felt about the future...
wrote:
They are terrified, but determined to keep fighting...

“Sometimes it is almost impossible not to feel hopeless and broken,” ... “We keep doing it because we have to do it, so [the powerful] cannot say that they didn’t know. We know what we’re talking about. They can say they don’t care, but they can’t say they didn’t know.”...

... The task climate researchers have dedicated themselves to is to paint a picture of the possible worlds ahead. From experts in the atmosphere and oceans, energy and agriculture, economics and politics, the mood of almost all those the Guardian heard from was grim. And the future many painted was harrowing: famines, mass migration, conflict. “I find it infuriating, distressing, overwhelming,” said one expert, who chose not to be named. “I’m relieved that I do not have children, knowing what the future holds,”...

... So how do the scientists cope with their work being ignored for decades, and living in a world their findings indicate is on a “highway to hell”?...

... “The big difference [with the most recent IPCC report] was that all of the scientists I worked with were incredibly frustrated. Everyone was at the end of their rope, asking: what the fuck do we have to do to get through to people how bad this really is?”

“Scientists are human: we are also people living on this Earth, who are also experiencing the impacts of climate change, who also have children, and who also have worries about the future,” said Schipper. “We did our science, we put this really good report together and – wow – it really didn’t make a difference on the policy. It’s very difficult to see that, every time.”

Climate change is our “unescapable reality”...

... In the climate crisis, even fractions of a degree do matter: every extra tenth means 140 million more people suffering in dangerous heat...

... The climate emergency is already here...

... In the face of such colossal danger, why is the world’s response so slow and inadequate? The IPCC experts overwhelmingly pointed to one barrier: lack of political will ... also blaming vested corporate interests...



Oh what to do?

Well, I for one ain't going to roll over to get burnt and die on this one!

Will you?

Oh the stupidity of the fossil fuel industry.

On 1 hand they're advertising the so called benefits of natural gas power generation that can be turned on or off at need (instead of the constant full on production from coal and nuclear power generators, the later due to the huge startup costs involved), but on the other hand they're warning us of running out of it, yet they're selling the stuff overseas at rates well below that of local pricing while more foreign companies circle in for takeovers just to make things even worse.

Why the global fossil fuel sharks are circling Australia's gas export industry.

For an industry entering its sunset years, Australian gas certainly is attracting an enormous amount of attention and money.

Last week, that great laggard of the investment world, Santos, was rumoured to be in the sights of two of the world's biggest fossil fuel outfits, Saudi Arabia's Aramco and the UAE's Abu Dhabi National Oil Company, in a potential $25 billion break-up.

Late last year, Australian giant Woodside approached the group as well, proposing an $80 billion merger that would have catapulted the pair into the top tier of global petrochemical giants. But the deal went nowhere.

And for much of 2023, two huge North American investment groups sought to capture Origin Energy in a $20 billion deal that would have split the Australian energy giant.

That deal was stymied at the final post by Australian Super, which marshalled enough support to vote down the deal on the floor at the extraordinary general meeting just before Christmas.

Since then, there's been talk Canadian infrastructure group Brookfield, one of the bidders, may return with a counteroffer, given the super fund's objections centred primarily around value.......
The stupidity of it all just seems to be a race between them all to the end while ripping as many off as they can in the process. :-(

I agree with you on coal; it's difficult and expensive to upgrade coal (more so lignite) power plants for flexible generation output following current demand and balancing Renewables. But natural gas is an almost perfect fuel. It's clean (no expensive cleaning of exhaust fumes). It can be stored cheaply underground without losses. Long distance transport by means of pipelines is cheap. Gas enables ultra-efficient heat generation. Combined cycle gas turbines (gas and steam turbine) are the most efficient (thermodynamics) power plants we have. Few employees are needed to operate them, even remote control is common. Power output of gas turbines can be adjusted quickly to demand. (a sidenote: not as quickly as latest generation of nuclear PPs between 100% and ~60% output).

That is why we will use gas and LNG for the foreseeable future until renewables can replace them completely, or batteries... or nuclear or a sensible combination of them.
But we should take a calculator today and truly assess: How much CO2 is exhausted to produce, process, and transport Gas resp. LNG from the well to the comsumer. It seems to me that we are not doing this honestly when importing LNG from Australia to Europe. I doubt the general assumption LNG is more climate friendly than coal or lignite.

We could be in big trouble.

Record 50C temperature increase over Antarctica to shift Australia's weather patterns.

Earlier this July, the temperature more than 20 kilometres above the east Antarctic coastline suddenly warmed by about 50 degrees Celsius in a week — an event called a sudden stratospheric warming (SSW).

While SSWs occur every other year in the northern hemisphere, they are extremely rare in the southern hemisphere, and have never previously been observed in winter.

The rapid polar warming is now beginning to filter down towards the surface in the form of higher pressure over Antarctica, a set-up which has the potential to impact Australia's weather through August and possibly well into spring.

The term SSW is used to describe a rapid warming over either the Arctic or Antarctic, which reduces the temperature contrast between the cold poles and milder mid latitudes.

Since upper-level winds are driven by a thermal gradient, this warming leads to a breakdown of the polar vortex, or in other words, a significant weakening of the fierce stratospheric westerly winds that circumnavigate the poles.

Typically this sudden change over the stratosphere will then filter down and disrupt the troposphere (the layer of atmosphere where weather occurs), which can result in prolonged spells of extreme weather for weeks.

The strongest SSW events even cause a reversal in winds around the polar vortex from a westerly to an easterly, including the infamous "Beast From the East" winter storm in Europe through February 2018........

No surprises here:


‘Massive disinformation campaign’ is slowing global transition to green energy
wrote:
Fossil fuel companies are running “a massive mis- and disinformation campaign” so that countries will slow down the adoption of renewable energy and the speed with which they “transition away” from a carbon-intensive economy...

... “There is this prevailing narrative – and a lot of it is being pushed by the fossil fuel industry and their enablers – that climate action is too difficult, it’s too expensive,” he said. “It is absolutely critical that leaders, and all of us, push back and explain to people the value of climate action, but also the consequences of climate inaction.”...

... Yet the world has never been better equipped to tackle climate breakdown, Hart added. “Renewables are the cheapest they’ve ever been, the pace of the energy transition is accelerating,”...

... “Despite everything we see [in the form of extreme weather], we’re still not seeing the level of ambition or action that the world desperately needs.”



So?

What do we do about that?

There still are not many. Currently, the Russians only clear the entrances to their Arctic ports and the sea accesses into the major Siberian rivers for shipping during summer season. But the Russians and China prepare to establish reliable shipping routes from Europe to East Asia; in the beginning at least during summer seasons along the arctic coastline. As soon as more Russians and Chinese start shipping around there, the Canadians and Americans will be required to secure their sovereignty up there, otherwise Chinese Arctic 'research stations' (like they do in Antarctica) will pop up everywhere. A vicious circle.

I don't want to think about how Russian negligence in transport safety and environmental protection will affect this unique region in the near future. We would also prefer to ban them from sailing their ancient junk oil tankers through the very narrow Baltic Sea just a few miles off our and Danish coastlines. The Danes already think about banning their junk ships from the narrow Danish Straits, which are territorial Danish waters. But banning them from the entrances into the Baltic Sea means blocking most of their sea trade into the European part of Russia, that is a declaration of (economic) war. They could simply use modern and safe tankers but they always prefer to be the powerful, angry grizzly when somebody dares to criticize their habits.

Compare with this year's arctic sea ice extent:

This is the route of Fridtjof Nansen's three-year "Fram" polar expedition (1893-1896). Nansen advanced in summer along the Russian arctic around Cape Chelyuskin to the New Siberian Islands, where he steered his ship intentionally into the pack ice, so that it was driven by the Arctic sea ice drift towards Greenland within three years. Nansen had to sail close to the Russian coast (red line) to somehow get through there in the high summer with a lot of drift ice, which was difficult and required him lots of zigzaging, even reversing course.

On July 18th he left (Vardø/Norway), on Sept 28th he began the ice drift (blue line) west of the New Siberian Islands, which ended three years later at Spitsbergen (Aug 1896). Nansen unsuccessfully tried to reach the North Pole with sledges (March to August 1895) across the drifting ice ending up in Franz Josef Land (green line).

I wonder what the deniers will say when this happens.

Antarctic 'Doomsday Glacier' Heading for Collapse.

Scientists studying Thwaites Glacier, ominously dubbed the "Doomsday Glacier," have unveiled a rapidly evolving and complex environment that could lead to dramatic sea-level rise in the centuries ahead. The glacier, located in West Antarctica, has become a focal point of global concern due to its potential to significantly impact coastal communities around the world.

Since 2018, the International Thwaites Glacier Collaboration (ITGC), a joint research initiative between the U.K. and the U.S., has been closely monitoring this immense glacier, which is roughly the size of Florida. Its latest findings reveal alarming trends in ice loss and indicate a heightened risk of collapse.

"Thwaites has been retreating for more than 80 years, accelerating considerably over the past 30 years, and our findings indicate it is set to retreat further and faster," Rob Larter, science coordinator of ITGC and a marine geophysicist at the British Antarctic Survey (BAS), said in a statement.

If Thwaites collapses, the consequences would be catastrophic. Stretching more than 70 miles wide and over 6,500 feet thick, its collapse could expose millions of people in vulnerable low-lying areas—like Bangladesh and the Pacific Islands—to rising sea levels. Major cities, including New York and London, also face increased risk, according to the BAS.......

.......By the 23rd century, Thwaites and much of the West Antarctic Ice Sheet could be completely lost, the ITGC said. Thwaites alone holds enough ice to raise global sea levels by more than two feet. If the entire ice sheet it protects also collapses, sea levels could rise by over 10 feet—an outcome that would drastically reshape global coastlines......

There has to be a better way:


Van Gogh is turning in his grave at the harsh Just Stop Oil sentence. I know, because I spoke to him
wrote:
Nature was the painter’s ultimate muse, and he would have admired those seeking to protect it...

I woke up to a call from Vincent van Gogh today. He told me he wants the Just Stop Oil protesters who threw soup on his Sunflowers to be released immediately. I nodded and promised to do everything I could to ensure Phoebe and Anna would be freed soon...

... There was no damage to the Van Gogh painting...



To my mind, the sentences handed out to those young adults looks to be extreme. Those prison sentences are long enough to leave them scarred for life. And for what? Throwing a cup of cold soup?

And yet the fossil fuels CEOs burn and pollute our planet with profitable impunity!

Garbage in, garbage out.....
Guess what, burning rubbish is really bad, as bad as coal:
https://www.bbc.co.uk/news/articles/cp3wxgje5pwo

The trouble is - what to do with the vast amounts of rubbish modern society develops?
The simple answer is not to produce so much in the first place, but all too often modern packaging beats the recycling system by using (almost) unseperable combinations of different plastics and "wood" products, for example recyclable padded shipping bags that are made from paper, card and a couple of different plastics glued and melted together that are great for holding the contents together but take great ingenuity to separate into the different materials, thus most people just give up and throw into the general waste bin (which goes to either landfill or incineration).
