VOX: “We Could Quickly Get Used to Climate Chaos”

Guest essay by Eric Worrall

VOX author David Roberts is worried we shall never wake up to the need to address the climate crisis, because we will just get used to it.

The scariest thing about global warming (and Covid-19)

“Shifting baselines syndrome” means we could quickly get used to climate chaos.

For as long as I’ve followed global warming, advocates and activists have shared a certain faith: When the impacts get really bad, people will act. 

Maybe it will be an especially destructive hurricane, heat wave, or flood. Maybe it will be multiple disasters at once. But at some point, the severity of the problem will become self-evident, sweeping away any remaining doubt or hesitation and prompting a wave of action.

From this perspective, the scary possibility is that the moment of reckoning will come too late. There’s a time lag in climate change — the effects being felt now trace back to gases emitted decades ago. By the time things get bad enough, many further devastating and irreversible changes will already be “baked in” by past emissions. We might not wake up in time.

That is indeed a scary possibility. But there is a scarier possibility, in many ways more plausible: We never really wake up at all. 

No moment of reckoning arrives. The atmosphere becomes progressively more unstable, but it never does so fast enough, dramatically enough, to command the sustained attention of any particular generation of human beings. Instead, it is treated as rising background noise.

We adjust; we can’t help it. If we wait for ecological change to thrust itself into the consciousness of ordinary Americans, we may be waiting forever.

Shifting baselines apply to several other social problems

Once you start thinking in terms of shifting baselines, you start seeing them everywhere, not just in ecology.

What is the unending debate over the “normalization” of Trump but a debate over shifting baselines? President Trump has degraded and discarded longstanding norms of presidential behavior with astonishing speed and recklessness, but it has proven incredibly difficult for the press and the public to assess his record based on pre-Trump baselines. This is why people are always asking, “What if Obama did this?” They are trying to ask, “Why have we shifted our moral and political baselines so quickly?”

What if Americans simply accommodate themselves to thousands of coronavirus deaths a day? As writer Charlie Warzel noted in a recent column, it’s not that different from the numbness they now feel in the face of gun violence. “Unsure how — or perhaps unable — to process tragedy at scale,” he writes, “we get used to it.”

If the climate crisis is just another problem to be addressed, rather than an existential crisis which eclipses all other considerations, then it has to compete for attention with other societal problems.

There is no evidence climate change is an especially important problem, no evidence it deserves special attention, given the long term drop in the annual number of deaths from weather related disasters.

New study detects ringing of the global atmosphere


Researchers now want to ‘understand both the processes that excite the waves and the processes that act to damp the waves.’
– – –
A ringing bell vibrates simultaneously at a low-pitched fundamental tone and at many higher-pitched overtones, producing a pleasant musical sound, says Phys.org.

A recent study, just published in the Journal of the Atmospheric Sciences by scientists at Kyoto University and the University of Hawaii at Mānoa, shows that the Earth’s entire atmosphere vibrates in an analogous manner, in a striking confirmation of theories developed by physicists over the last two centuries.

In the case of the atmosphere, the “music” comes not as a sound we could hear, but in the form of large-scale waves of atmospheric pressure spanning the globe and traveling around the equator, some moving east-to-west and others west-to-east.

Each of these waves is a resonant vibration of the global atmosphere, analogous to one of the resonant pitches of a bell. The basic understanding of these atmospheric resonances began with seminal insights at the beginning of the 19th century by one of history’s greatest scientists, the French physicist and mathematician Pierre-Simon Laplace.

Research by physicists over the subsequent two centuries refined the theory and led to detailed predictions of the wave frequencies that should be present in the atmosphere. However, the actual detection of such waves in the real world has lagged behind the theory.

Now in a new study by Takatoshi Sakazaki, an assistant professor at the Kyoto University Graduate School of Science, and Kevin Hamilton, an Emeritus Professor in the Department of Atmospheric Sciences and the International Pacific Research Center at the University of Hawaii at Mānoa, the authors present a detailed analysis of observed atmospheric pressure over the globe every hour for 38 years.

The results clearly revealed the presence of dozens of the predicted wave modes.

Watching the Three Gorges Dam

Eyes are still on the Three Gorges Dam as a rare flooding event spreads across Asia. Bridges that have stood for 500 years have succumbed.

Pity the poor people of Wuhan, the flood waters released from the Three Gorges Dam have arrived. That dam and all upstream dams have opened the flood gates, and cities as far downstream as Wuhan are flooding.

According to the South China Morning Post, 19,380,000 people have been affected by flooding across China as of July 3rd. Chriss Street says “a record 16.8 inches falling between Sunday and Monday morning, and inflows running at 40 acre-feet per second after, CMA on July 4 issued an 80-percent risk of thundershowers for each of the next 11 days.”

Check out the brief shot of the flood in a supermarket.

Apparently the dam is so large and heavy it even ranks in discussions of seismic potential – namely that some people are concerned the weight of the water may trigger earthquakes.

The “word on the street” according to Gravitasis that Chinese people are wondering if the flooding water released from  is convenient for the CCP government to wash away […]

John Constable: Why Europe’s ‘Green’ Hydrogen Hype Is Likely To Flop

By Paul Homewood

 

A timely intervention by Dr John Constable:

Hydrogen is dangerous; hydrogen is safe; hydrogen is cheap; hydrogen is very expensive; hydrogen is old hat; hydrogen is the future. Hydrogen is… all things to all men, and every one of these contradictory claims is more or less true from some perspective. Whatever hydrogen is, it is a very buoyant gas and makes for the perfect climate political football. Indeed, the authentic promise of hydrogen is rapidly becoming the victim of failing green policies.

As renewables run into the thermodynamic sands all over the world, desperate advocates are covering up their disastrously bad advice by calling for still more ambitious, Net Zero emissions targets. To make these extreme demands look plausible hydrogen is invoked as an energy carrier for those sectors where it is most difficult to create the appearance of decarbonisation.

The United Kingdom is a good example of the emerging European approach. The UK is planning to burn hydrogen rather than natural gas to generate electricity to balance and secure the unstable wind and solar system created by $12 billion a year in subsidy. Hydrogen will replace diesel for agricultural traction and for trucks, and will supply almost all industrial process heat. Converted to ammonia, hydrogen will replace bunker fuels for marine transport. And to ensure that domestic households don’t resort to resistive electric heating when their Ground and Air Source Heat Pumps fail to deliver on the coldest days of the year, every house will have a back-up hydrogen fuelled boiler.

For climate policy makers suffering from Net Zero headaches hydrogen is the universal aspirin. Take as many as you need, and lie down in a darkened room until the news cycle moves on.

But this desperate face-saving haste means that hydrogen must be generated by two relatively unsophisticated commodity production processes, namely the electrolysis of water and the chemical reforming of natural gas using steam (Steam Methane Reforming). Both processes are acceptable if hydrogen is required for niche and non-energy purposes, but it is a plain foolish to suggest using them for the production of hydrogen as a society-wide energy carrier. There are four principal disadvantages.

Firstly, the costs will be huge. Steam Methane Reformers and electrolysers are expensive to build and to run, and electrolysers at least do not have long plant lives, implying a short capital refreshment cycle. To this we can add the replacement of end conversion devices and the establishment of hydrogen infrastructure, pipelines, and storage systems ranging from tanks to salt caverns.

Secondly, due to conversion and storage losses, hydrogen from electrolysis and SMR can never in principle compete economically with its own input fuels. The consumer will always be better served by using the electricity and natural gas directly. Consequently, there will be substantial competitive advantages for economies that do not hobble themselves with hydrogen.

Thirdly, Steam Methane Reforming emits large quantities of carbon-dioxide, compromising any Net Zero target unless the SMRs are equipped with Carbon Capture and Sequestration, which is expensive and currently unavailable at scale. Indeed, what the current hype around hydrogen reveals is that the global Net Zero targets are in fact critically dependent on methane – the UK plans to derive 80% of its annual 270 TWh of hydrogen from SMRs – and are therefore a gamble on Carbon Capture. But if CCS becomes viable, which is possible, it will be more effective to use the methane directly in Combined Cycle Gas Turbines with CCS, and supply the consumer with electricity, and there would be no reason to make hydrogen, with all its attendant costs, problems and dangers.

Finally, the production of hydrogen from both electrolysis and SMRs uses large quantities of clean, fresh water. The UK’s current hydrogen target would increase national water consumption by between 1 and 2 percent at a time when climate policy advisors are themselves predicting a constrained fresh water supply, with deficits in a quarter of the country’s resource zones towards mid-century.

This is clearly bad hydrogen. Is there a good hydrogen? Perhaps. As long ago as the early 1970s the physicist Cesare Marchetti, then EURATOM, persuaded the Japanese government that hydrogen might have a future as a universal energy carrier if it was generated from a very high quality energy source, such as high temperature nuclear reactors, and through the thermal decomposition of sea-water in the presence of a suitable catalyst. Japan continues to work quietly on this. But the nuclear and chemical engineering problems are of the first order, and results will not come quickly. But at least the concept has authentic physical promise.

Indeed, it is perhaps the only fossil-free energy future that also preserves human well-being. Those jeopardising that future by forcing rapid and sub-optimal adoption of hydrogen in order to prolong the current mal-engineered renewables farce should hang their heads in shame.

For more information about the cost, benefit and limits of hydrogen see John Constable’s new report Hydrogen: The Once And Future Fuel (pdf)

Constable neatly sums up the real reason behind the new found fervour for hydrogen. It is not because hydrogen has anything going for it. It is because the EU has boxed itself into a corner with its disastrous and ill thought out decarbonisation agenda.

Reality has finally dawned that renewable energy cannot do the heavy lifting, and now they have nowhere else to turn.

It reminds me of that song, “There was an old lady who swallowed a fly!”
