Aberfan and Farnborough Disasters 18 October 2016

Received 18 OCTOBER 2016
Published 18 OCTOBER 2016
From Keith Montague

Sir, Interesting that you link the Farnborough crash and the Aberfan tragedy in your excellent leader (Geoscientist 26.09 October 2016). I have a personal interest in both; a direct one for Farnborough as I was there that day, and a tangential one for Aberfan partly because it occurred on the day of my grandfather’s funeral and I well recall watching the television news that evening (in black and white – Aberfan will always for me be black and white), and partly because my specialism was geotechnical engineering.

The link you make about there being no prosecutions, no persons held responsible, no resignations is of course not completely valid. In 1952 everyone was aware that prototype aircraft would crash and that air shows were places for derring-do activities by test pilots. John Derry was performing the very first supersonic ‘bang’ at an air show and had done this successfully on each of the previous days (Neville Duke followed the crash with just such a bang).

Anyone attending an air show knew that they might well see a crash; what was less expected was that members of the public would be killed. Yet it is true that, in that post-war period, we were much more philosophical and less likely to find blame.  A better comparison would have been with the Crichel Down affair of 1954 where a catalogue of official incompetence and deceit did, indeed, lead to a ministerial resignation. 

I had first been taken to Farnborough in 1951 as an eight year-old by my father, who was in the aviation industry. That year we watched from the ‘hill’, the best vantage point. The following year we were delayed at Waterloo and were too late for the hill – we had to sit on lower ground – but the hill was, of course, where the engine was to fall that killed so many people. I well remember asking my father, as the engines flew overhead, “what are those Daddy?”.  The full impact of what had happened was initially lost on me.

Without that delayed train at Waterloo, I might well not be here to correspond with you.

Sir, Like many other members, I use the library and Fellows' room infrequently, but value the 'meaning' this gives of being able to use the facilities and I have used the fellows room on a number of occasions. 

I hope it is restored to the use of fellows in the future - so please use this letter as an indication of 'discontent' at its current unavailability. I live in Malawi, but will remain a Fellow and will expect to use the library again in person when I return to the UK.

Once it is restored to its proper function, I would be more inclined to use the facilities more frequently if the Fellows' room were given a bit of a face-lift in terms of furniture and made a little more welcoming!

Crossing the Merdesey 13 September 2016

Received 13 SEPTEMBER 2016
Published 13 SEPTEMBER 2016
From George Reeves

Sir, Recent discussions (including at the IGC in Capetown) and attendant UK press publicity (especially The Guardian, front page, September 30) reminded me of a formative geological field-class experience in the late 1960s.

The class of budding second-year sedimentologists found themselves in the capable hands of the late Robin Bathurst, fresh from diving and snorkelling research activities in the Bahamas , which illustrated his inspirational lectures to us. This was just prior to the publication of his seminal Carbonate Sediments and their Diagenesis, Elsevier, 1971.  The banks of the River Mersey, just outside the river mouth at Formby, were a far cry from the Caribbean, however!

It was a beautiful crisp autumnal early morning fieldwork session on ‘Modern Sedimentology’, and we were promised warm drinks and sustenance if the weather was inclement, at the Bathurst establishment nearby. 

As the tide rose on the sandbanks adjacent to the Formby dunes, it found us discussing Man’s effects on the environment, with the flotsam and jetsam of a rising Irish Sea tide, and lots of boats coming and going to the docks of Liverpool.

Robin, in his inimitable way, as usual led the discussion, with sediment transport examples being pointed out and analysed, in the sandbanks and growing tidal pools, as the group traversed the foreshore.

I do remember small examples of sediment movement being discussed, and the term "Turdibites" (sic), being coined.  (By now, you might see where the lowering tone of this 45 year-old reminiscence might be going.)

As some will remember, the Mersey, like many other rivers in the north of England, was not exactly clean and wholesome in the 1960s and '70s.  One student wag, contributed to the discussion thus: "This mess of sedimentary garbage can only mean one thing- that the next Geological Age will be called 'The Obscene'!" which a local enthusiastic student with an interest in palaeontology added: “and I suppose that the indicator/trace fossils will be Londinium rubericum or 'Mersey Trout', as we know them!”

Sir, This article (SCARP - a Scottish Carboniferous research park by Leslie and Brown, Geoscientist 26.07 August 2016) took me back many years when, as a new graduate, I joined the NCB Opencast Executive based in the Midland Valley of Scotland. 

Having the opportunity to see the Coal Measures exposed in an opencast face was a real education in geology, better than any lecture theatre or text book, and it opened up a career path in coal which I have enjoyed ever since - although some 11,000km further south!

Turning these old opencast sites into a geological theme park, or whatever we want to call them, is a great way of showing people the real nature of geology with faults, folds and fossils for all to see ... and not imagine.

Received 17 AUGUST 2016

From Rob McLaverty

Sir, I can't help but feel the Geological Society is not fully utilising the talent of its younger members.  The Society could benefit hugely from younger members' enthusiasm and ambition, and in return offer an opportunity for those in their early career to show their work and extend their network.

Some quick wins that would be easy to implement to galvanise us younger crowd could be: a monthly feature in Geoscientist, researched and written by a "young geoscientist"; having a Young Geoscientist Representative on the Council (or a Young Geoscientist sub-committee); and giving new young members an option to join a nation-wide ‘Young Geoscientist Group’ when they become fellows or candidate fellows (beyond just a Facebook Group!).

Why not continue the success of the Early Career Award by giving young people more opportunities to connect with each other and the community? At the same time the Society will be securing its future for the years ahead.

Luddite? Moi? How very dare you! 12 August 2016

Received 12 AUGUST 2016
Published 12 AUGUST 2016
From Richard Arthur

Sir, your edited version of my letter published in the July Geoscientist included my humor but omitted a serious point which I was attempting to make regarding the Society’s support for fieldwork.  My comments were not born out of Luddism, as the headline suggested, but out of concern to stop the erosion of professional standards and make clear exactly what makes a geologist.

P M Carruthers was moved to write ‘Fieldwork’s importance overstated’ (Geoscientist Vol 27.4).  I doubt that anyone in their right mind, and certainly no geologist worth their ‘evaporite’, could fail to see the importance of fieldwork.  We simply cannot afford to give even the slightest excuse for the financially motivated etc. to abrade time, money or curriculum set aside for fieldwork. 

Those who are completely seduced by all things computer all to often seem to lack common sense and be oblivious to the idea of working from basic first principles  -  it is for this reason alone I have grave reservations about such technophiles.

3D geological model limited by Victorian mapping 10 August 2016

Received 10 AUGUST 2016
Published 10 AUGUST 2016
From David Nowell

Sir, Though the British Geological Survey report on 3D geological model of the superficial deposits of the Holderness area in East Yorkshire, upon which the feature about Models and Flooding (July 2016) was based is highly impressive, it is constrained by geological mapping dating back to the 1880s. Thus, one of the report's key conclusions is the need for more detailed borehole information to gain a fuller understanding of the till sequence and glacial stratigraphy, without acknowledging the need for fresh geological mapping enhanced by NEXTMap radar topographic imaging.

Backed up by geophysical surveys, this could be highly effective in delineating sands and gravels, rather than relying on the random accumulation of borehole records to plot their apparent extent.  Also it's odd that Holderness Meer is not shown with an uncertain striped permeability when it is being recharged through the superficial deposits, and Swan island in the middle is show as highly permeable.    

The composite geological map in the report (Figure 8) shows hitherto unmapped superficial deposits. This includes nearly a square kilometre of glaciofluvial gravel in Beverly adjacent to an area of exposed Chalk rather than till still shown on the bowdlerized online geology of Britain viewer, which promptly contracts itself when you pick though the borehole records. However this does not replace the need for integrated 10k geological mapping, so that even the Environment Agency who commissioned this report have been sold short.  

Without this, it is impossible to publish new 50k sheets (Proceedings of the Geologists' Association Vol. 127 (4), 422-424) 2016) so that people including local authority officers and councillors can have unbiased information about their ground conditions. Almost the entire area is covered by oil and gas exploration licenses, so it is vital that sensible objections to the siting of fracking pads and lorry routes damaging side-roads can be heard, rather than the whole debate becoming toxic and increasingly ill-informed. Perhaps this is why the 2015 BRGM annual report states that geological maps of France are essential for a wide range of uses and users and they continue to publish fresh 50k editions.

Sir, I read your editorial (Geoscientist 26.07 August 2016) relating to the temporary loss of the Fellows' Room to Fellows.  The removal of this important facility represents a significant deprivation to the Geological Society's Fellowship. For those of us who live and work a long way from London, the importance of things like a fully functioning Website and the knowledge that we could if we wish, make use of a room in Burlington House are not to be underestimated.

This lack of availability only serves to further increases the distance between the geographically more remote fraction of the Society's Fellowship and those who provide its administration.

Rise of the machines 01 August 2016

Received 01 AUGUST 2016
Published 01 AUGUST 2016
From Rob Wallace

Sir, The recent article by Martin Geach (Geoscientist 26.05 June 2016) and the letter from Chris Garland on computer mapping reminded me of some work I was involved in in the mid-1970s as computers became powerful enough to create reasonable maps.

I was assisting a team at Phillips in Oklahoma who were working (along with other oil companies) with the University of Kansas on the potential & the problems.  Almost all the issues identified then (some discussed by Chris) still occur today. 

At one meeting a ‘Super Major’ detailed some in-house research.  They generated a posted base map (2D data) and sent it to around 40 of their experienced geophysicists (+10 years) in various offices around the world to hand-contour.   The values on the map were extracted from a dataset in the USA but it was as ‘vanilla’ as possible.   No information was provided to the interpreters.

When the maps came back they were all very different – the one from Houston clearly envisioned listric faulting, the Louisiana office seemed to show salt domes, the Stavanger office tilted fault blocks etc etc . 

In other words, hand contouring reflected the inbuilt bias of the interpreter.

They then proceeded to average the maps in some way, and were surprised to discover that the final map looked very like the computer-generated map they had from the same data set!

Their conclusion was that computer generated maps are comparatively unbiased and (importantly) easy to duplicate by anyone using the same input parameters.   The problem is that the interpreters bias (or knowledge) may make all the difference in correctly mapping geological phenomena. 

Unfortunately you rarely see hand-drawn maps these days – the speed and convenience of pressing a button seems to override the need for interpreter bias.  I know that 3D data really does constrain the options but there is still a lot of mapping of 2D and scattered well values that could do with a more thoughtful approach.

Brexit explained (sort of) by geology 30 June 2016

Received 30 JUNE 2016
Published 30 JUNE 2016
From Micky Allen

Sir, It is not generally appreciated that the recent UK referendum to leave the EU (‘Brexit’) was directly caused by exploration geologists (and could possibly explain the recent resignation of the boss of Rio Tinto).

If you ask a geologist to find you a nice mineral deposit they usually discover another two (whether it is gold, uranium or iron-ore).  The plethora of iron-ore mines due to come on stream has meant an oversupply of this commodity.  However as neither BHP nor Rio Tinto were willing to cut back production, the price fell dramatically.

The only country that could now produce steel at a profit was China. China dumped steel in the west and, as UK steel plants were losing money they were then shutdown (Redcar, Llanwern, Port Talbot).  This produced social unrest in the UK 's already depressed areas, which voted for Brexit.

And this is why there are no more jobs for exploration geologists.  It’s society's punishment for the after effects of the UK referendum!  Simples.

Field v Mouse 30 June 2016

Received 30 JUNE 2016
Published 30 JUNE 2016
From Tom Elder

Sir, My PhD thesis involved the study of the geology of the eastern half of what is termed the Levang Peninsula in southern Norway, just south of Kragerø. The western end fell to a student at Nottingham. Happily, my NATO scholarship enabled me to spend two whole years in Norway at Oslo University (1960 - 62), of which more than half my time was spent in the field. 

My Nottingham colleague, who preferred to spend his time peering down a microscope at mineral samples in the lab, concluded that it was an intrusive granite. My field work, meanwhile, enabled me to demonstrate conclusively the presence of a ghost stratigraphy resulting from essentially in situ granitisation.

And yes - I don’t think one can overstate the importance of field work!

Ha det bra så lenge!

Extrapolation: fantasy v. reality 13 June 2016

Received 13 JUNE 2016
Published 13 JUNE 2016
From Chris Garland

Sir, Martin Geach (Soapbox, Geoscientist 26.5 June 2016) is raising an issue that was familiar to many petroleum geologists in the eighties: computer mapping of geological structures.  This old chestnut seems to have echoed across the decades and still resonates today.  I remember many a heated discussion about algorithms during interminable meetings to agree procedures for mapping oil and gas fields that crossed North Sea block boundaries and could vary in shape and volume distribution depending on which interpolation technique was used in CPS-1 or Zmap. 

Data points (ie wells) were usually more than 200m apart, unlike Martin’s example.  Although our volumes were measured from a surface down to a plane (eg the gas-water contact) the volumes, and the distribution of volumes by block, could vary widely between methods.  Martin’s examples of Kriging and IDW methods are almost incredibly close in their volumetric results.  However, the difference between them and the RBF/RST method is more than a factor of two - an intolerable outcome.

I suspect a wild over-extrapolation in the NE corner of the RBF/RST model where data are absent (as shown by the curious shape of contours in this area in the Kriging and IDW examples) and the algorithm has generated an unrealistically deep hole in the model.  This also occurs in the SW, where it appears the depths are much greater (indigo colour) in the RBF/RST model than in the other two models.  A rotation of the 3D view to show the depth axis, or a couple of cross-sections sliced across the model, would clearly reveal these reckless departures which, unless corroborated by real data points, should be eliminated by the geologist.  At least, they should if these deep troughs lie on my side of the block boundary!

Sir, It is very hard for me to express my acute frustration at the seemingly never-ending lack of availability of the Society's on-line CPD reporting facility.

The Geological Society, one of the oldest and most erudite scientific institutions in the world, can't seem to be able to provide a functional website for its Fellows. I (foolishly) intended to maintain my personal CPD records here (compulsory for CGeol). The facility has been unavailable for very many months, so I'm forced to look to another institution for assistance.

I'm affiliated to a a couple of other professional organizations; the Institute of Quarrying and the Institute of Materials, Minerals & Mining, all with annual subscriptions that are far lower than the Geological Society's and all with consistently reliable and fully operational websites.

Professionalism really must start at home. Please get it to together guys!

Blessed are the data handlers 27 May 2016

Received 27 MAY 2016
Published 27 MAY 2016
From Findlay Craig

Sir, I will never dispute that ‘the best geologist is the one who has seen the most rocks’, but am finding the repeated emphasis on field geology ‘über alles’ increasingly shrill.  Data gathered in the field only becomes valuable once we have analysed and understood it, and produced a predictive model.

This interpretation relies heavily on data being ‘clean’, organised, and in a usable format.  In order to meet reporting standards it is necessary to track any interpretive changes that deviate from the original field logging.  From beginning to end, data must be handled so as to preserve user trust.

As a consultant I have seen dozens of datasets of different kinds, from clients all across the world, from major players to minor operators.  In most instances, I would class their data storage and handling as ‘poor to middling’.  And neither size nor reputation of company, nor geographic location, have any bearing on the quality of their datasets. 

Long gone are the days when an entire mineral deposit could be mapped on paper, interpreted on section on paper.  Nowadays that work is done on computers, running specialist software, needing solid databases to work from.  Field studies and drilling programs cost money, and the value of the data won is very quickly lost if it is stored incorrectly.  Poor data storage costs more in the long run than it saves in the short term.

We may not like the fact that a large portion of a geologist’s life these days consists of moving columns of data around rather than licking rocks.  But it is here to stay, and we should show more appreciation of the value added to our work by the ‘dull’ task of maintaining good quality databases!

Nepal - not all its seisms 27 May 2016

Received 27 MAY 2016
Published 27 MAY 2016
From Len Fisher and Bleddyn Griffith

Sir, In the aftermath of the earthquake tragedy in Nepal, scientists are rightly studying the seismic factors that can give rise to further landslides (Nature 532, 428 - 431; 2016). Such studies are of inestimable value for many earthquake-prone regions around the world.

However, the situation in Nepal is exacerbated by two additional factors. One is that the foreland zone of the Himalayas, home to most of the population, consists primarily of clastic sediments produced by the uplift and erosion of the Himalayas and deposited by rivers (R B Sorkhabi & A Macfarlane, Himalaya and Tibet: Mountain Roots to Mountain Tops, Geol. Survey of America Spec. Pap. 328, 1-8; 1999).

It is relatively easy to bulldoze a basic road through this material, but such roads are subject to slow settlement, and the steep water-saturated slopes through which they are driven are liable to slippage at any time and at any scale when the steepness or saturation reach critical values (P. Bak et al., Phys. Rev. A 38, 364-374; 1987). This means that better seismological understanding and measurement can contribute only partly to a solution.

The other factor is the presence at high altitude of 1466 glacial lakes, the banks of any one of which may collapse to release its contents and produce a devastating flood that destroys roads and villages further down the mountain. Seismic events can precipitate such collapse, but so can heavy rain, snow, or the attainment of critical conditions.

Monitoring of seismic tremors gives warning of possible events, but what Nepal desperately needs is a system of monitoring and communication that addresses actual events so that, when the inevitable occurs, warning can be given in time for populations to escape from the path of the subsequent flood or landslide.  Roads, and even villages, can be replaced; people can’t.

Holistic fieldwork 27 May 2016

Received 27 MAY 2016
Published 27 MAY 2016
From Jane Robb

Sir, Geological fieldwork is not just about geology!  It is also about learning the value of nature, observation, and more physical problem-solving approaches unique to geoscience and rare in other non-vocational degree fields. 

With a large focus (in the fields of health, education and psychology) on the importance of the outdoors and nature to well-being, we should count ourselves lucky as geoscientists to have this activity embedded in our curriculum, and take more time to acknowledge the more holistic educational benefits of being able to look at, and interpret, a landscape. 

I continually find value in having had both academic and fieldwork training, both in work and social life.  Friends and colleagues have been amazed at how I can 'explain' a previously mundane landscape to them, through basic geological observations. 

I see this as incredibly valuable in inspiring wonder, in myself and others, about the natural world - with great potential for increasing public scientific literacy (e.g.  Geolodia Geoscientist 27.04 p16).  Finally, for those geoscience students who may be less academic in the 'traditional' sense, and prefer ‘learning through doing’, fieldwork is a fantastic way to ensure their potential is not wasted.

Fieldwork for subsurface geologists 27 May 2016

Published 27 MAY 2016
From Birger Hansen

Sir, Inspired by Mr Carruthers (Geoscientist 26.04, p 09), I would like to describe the role of fieldwork in my company.  We consult for the oil industry and all our studies are based on numerical data such as borehole images, petrophysical logs and pressure measurements.

Our geologists work all day in the sterile environment of an office.  They create various displays on a screen and try to imagine what real geology is going on down there at 5km, more inaccessible to humans than Mars.  Their results are maps and sections that look as if they were surface geological maps and mountainsides or road-cuts.  They use stereographic techniques the same way a field geologist does - with the difference that all data are acquired along a continuous curve, the well trace.

They constantly compare computed data with real rocks and real structures.  Despite our modest budget, we require each colleague to participate in at least one conference fieldtrip per year, and in an annual field trip we organise ourselves.  When recruiting, we select geology PhDs based on fieldwork.  The techniques peculiar to industry the candidates learn on the job. 

We do not sell fieldtrips to clients – we have no commercial axe to grind here.  The conference field trips usually present field analogues directly relating to our work on clients' oil fields, whereas the annual field trip focuses on wider topics including obduction, volcanism, rifting, fold/thrust belts.  All processes are connected; e.g.  structures in outcrop are the work of stress we observe in wellbores.

Yes, we seriously enjoy our field trips, and we could not do our work properly without it.  It is not a sin to enjoy one's job!

Inter Disciplinary Research - A Challenge for Geoscience 27 May 2016

Received 27 MAY 2016
Published 27 MAY 2016
From Alan Watson

Sir, Scientific discovery has always benefited from Inter-Disciplinary Research (IDR), enabling disparate subject areas to communicate in meaningful ways. This has never been more relevant than today when the understanding of Climate Change, DNA and Space Exploration have all involved multidisciplinary contributions. The corners of Science are moving closer and new understandings are emerging.

In May 2014 and again in July 2015 I provided letters following up on my research entitled Gravity and Mind which was first published in 2013. Broadly speaking, the nature of the work had been to gather evidence for a statistical relation between the incidence of riots on the one hand and the occurrence of earthquakes on the other.

The hypotheses tested a statistical link which requires the study of more than one area of science and this may explain the general lack of response to my work. I would imagine that some Geoscientists with their feet firmly grounded within the boundaries of conventional Geoscience may be skeptical, and they have remained unresponsive.

The research crossed boundaries between studies of the lithosphere and biosphere. Does the idea that we humans may be responding to our Dynamic Earth not generate any interest from an interdisciplinary perspective?

IDR is nothing new. Looking back historically, there are a great many examples of multi-disciplinary contributions to new discoveries. Going forward the recognition of the benefits of IDR presents a real challenge to Geoscience. Equally, IDR would present real opportunities and we must begin to look outward beyond the confines and comfort of our particular areas of interest.

Sir, I feel having Gary Nichols, Managing Director of Nautilus, “Largest single provider of field based training” make the case for field based training is like having the CEO of Ben ‘n Jerry’s make the case for ice cream.  Even worse, he doesn’t even make a good case.

We cannot walk along subterranean hydrocarbon reservoirs, but year-on-year enhanced recovery demonstrates we are doing something right. That would be the study of rock mechanics, fluid mechanics, porosity, permeability, reservoir pressures, injection pressures, flow rates, draw-down fluid contacts & so on.  Surely these are more laboratory sciences rather than field training?  It is not true that we can only study the vertical in well bores.  Most hydrocarbon based well paths now navigate horizontally through the reservoir with down-hole, real time tools which give fantastic resolution of rocks; particularly the measured physical properties so important  to evaluation & production.  We know there are commonly facies variations across reservoirs – no surprise there, but do field studies inform us on the best way to make reservoir fluids flow?

Continuing Personal Development (CPD) is an important aspect to everyone’s career & to companies’ success.  I would venture that the amount spent on Nautilus-type field training by energy sector companies versus everything else they put into individuals’ development approaches insignificance!

For our geological pioneers field study was indeed essential; they also rode around on horses & had no electric light.  Times change.  I like a day in the fresh air as much as the next person, so can’t we just be honest & say we go into the field because we enjoy it, rather than it being “essential or integral” to being a good geologist?

Now, where’s my ice cream?

Cutting remarks 16 February 2016

Received 16 FEBRUARY 2016
Published 16 FEBRUARY 2016
From Craig Bunting
Sir, I was very interested to read Gary Nichols' article Ground Truth concerning the advantages of fieldwork in the oil and gas industry - a point I completely agree with.  I have a masters degree, which I have to say has not actually helped me one jot to get into the oil and gas industry - that is, the operator's side of it, the side which gets much of the media attention.  However I wanted to spotlight another perspective.

There is a large body of geologists who work in my side of the industry - oilfield services - who do have considerable field experience: the mudlogging crews and wellsite geologists.  They catch and describe samples during the drilling stage and while this is not quite the same as looking at large exposures in the field, it does give first-hand observation of the reservoir formations as well as any oil they may hold.

The same detail visible through a hand lens on an exposure in the field can also be seen in cuttings samples taken usually every three metres (measured depth, not vertical depth) within the reservoir section.  It is routine for the mudlogging crew and wellsite geologists to describe the cementation, porosity and permeability characteristics of likely reservoir formations and record them on daily and end-of-well reports.  Add to this the interpretation of gas data and the advanced gas-monitoring and interpretation services, core, seismic and petrophysical data is greatly bolstered.  Any office-bound reservoir geologist can simply sit a modest x10 microscope on their desk and ask for the cuttings samples of a well to be delivered to them.

It is good to hear that some operators still value training because in these lean times it has completely stopped for geologists in oilfield service companies who are shedding staff in the hundreds and cancelling all non-profit-making expenditure to ultimately satisfy the shareholder.

Your Own Death and How to Cope With It 04 February 2016

Sir, The intrinsic human nature to embrace Armageddon at every and any given turn is as unlikely to dissipate and will likely hang around and haunt us as do the remnants of Amoco Cadiz, Exxon Valdez and BP's latest attempt at reducing biodiversity in the Gulf of Mexico. Apocalypse. We love it. We dream of it and yet it never seems to happen.

The ability of our minds to comprehend futures, societies and existences beyond that which we already know is at best limited. We all have versions but articulating a complete picture and comprehending it is another thing entirely. A little knowledge is indeed dangerous and with regard to predicting future trends among a complex web of interactions, is a mere folly, but we endeavour to do so whether in the face of futility or otherwise. There are many who have enlightened our imaginations with tales of greatness followed by disintegration - H.G. Wells, Jules Verne, Olaf Stapledon, Arthur C. Clarke, Rob Grant and Doug Naylor and many more have written the doom-laden futures of humanity that we repeatedly seek.

One thing that unifies them all is the acceptance that the increased demand of explosive societal needs or homogenisation are the downfall of Humankind. Reverend Thomas Robert Malthaus (1766 – 1834) predicted the demise of the human race due to an exponential demand for food and water that the agricultural practices of the day could not sustain. Not to worry, some time passes and there are technological solutions, societal changes and this of course affects the bottom line of altering supply and demand in a way that maintains our existence. Phew. I’m not dead after all.

So by that logic we are all ok as long as technology can fix it and society can adapt. Brilliant. This indeed backs up the argument supplied by David Nowell in Vol 26, No. 1 of Geoscientist. Aside from a quick dip into elevated temperatures possibly being bad, it is assumed that the whole world is being paranoid and the only reason we don’t want to drill in the arctic is because we’re a bit guilty of driving cars around and flying planes rather needlessly – to which I totally agree, we are addicted to oil and perversely defending it by capitalist measures. Can’t we leave some things alone?

What was clear from little Tommy Malthaus prediction was that something had to change or indeed we would be faced with significant famines and yet, things have and, disproportionately, we still are.

From the substantial desertification of Sub-Saharan Africa (and the modern day analogue with 30s dustbowl America that were once luscious plains), Latin America and Mongolia/China to global and regional overpopulation, bee and insect depletion, rising sea levels, overconsumption, fresh water resource depletion, invasive species, virus transportation due to globalisation, etc. it could be assumed we are living in perilous times. The anti-argument may be that we are always living in perilous times. Would that last statement be a bit remiss and blasé? (Maybe I am dead).

Of course it would. To merely state that the more environmentally aware scientists are blinkered and that humanity should have a good look at itself in the microverse is utter insanity. Fiddle away, Nero. Sanity would suggest the overloading of a system is not a good thing. Note the end Permian and end Cretaceous et al. There is so much to examine closely in society at the decision making levels. That does not render the journalist wrong, and to state it is “divisive” is grossly unfair and wrong. Aside from the fact that polemic is used to bring attentions to poorly reported matters, the reality is that we are addicted to oil and it will kill us by direct and indirect measures should we persist (what say you Rev. Tom?) along the same lines of irresponsible use. Perhaps we need to prove Malthaus wrong again, maybe that societal change and technological revolution at the higher levels is needed once more. Putting the blinkers on and blaming an SUV driving mum with a rather well fed child watching Red Dwarf (again) on DVD is probably not.

Hubbert's Peak, apples, and oranges 19 January 2016

Received 19 JANUARY 2016
Published 19 JANUARY 2016
From Antony Wyatt

Sir,  Hillis is correct to point out that Hubbert (1956) was predicting peak production, not exhaustion, of liquid hydrocarbons (and not other energy resources), but misses out that he was concerned with what were then considered to be conventional sources.

My understanding is that production from potential sources such as deep water and fracking were excluded from his calculations. To include these unconventional sources in a test of a Hubbert’s predictions seems a bit like comparing apples and oranges.

Hubbert's Peak not even 'correct' 13 January 2016

Received 06 JANUARY 2016
Published 13 JANUARY 2016
From Richard Hillis

Sir, Ragnarsdottir and Sverdrup in their article Limits to Growth revisited (Geoscientist 25.9) stated “Hubbert (correctly!) predicted an exhaustion date for the oil and energy resources of the United States as 1970”.  In fact the 1970 date refers to US liquid hydrocarbons (not other energy resources such as coal and uranium) and is Hubbert’s (1956) predicted peak production, not exhaustion, date. 

strjs Furthermore, and notwithstanding the enormous respect which Hubbert deserves for his body of work, as the figure illustrates, Hubbert’s (1956) prediction of US oil production is far from correct. The “peak resources community” cannot justifiably continue to use Hubbert’s (1956) prediction of future US oil production in support of their views.
