IPCC and consensus 08 March 2017

Received 08 MARCH 2017
Published 08 MARCH 2017
From Howard Dewhirst
Sir,  Nobody can disagree that there is climate change. As geologists, we know about the continual, and even continuous changes, that are the stratigraphic record; none would deny there has been an increase (but of ~1oC) in average world temperatures since ~1880, nor that CO2 is increasing; but many geologists and other scientists, do not accept that there is a proven, and unique scientific and unbreakable link, between CO2 and catastrophic, anthropogenic climate change. And it is far from clear that this ~1oC rise is not primarily a product of the repeated fluctuations in temperature recorded over the last 10,000 years - since the ice last retreated.

Climate modellers in the late 1970s changed from prophesying a nuclear winter, which for many years had been the buzz phrase linked to the global cooling that had taken place between ~1943 and ~1973, and particularly so while I was studying geology in the 60s, to warning about anthropogenic global warming. This claim appeared increasingly justifiable as the century aged, for the thirty years of warming showed an increasingly clear trend. Linking this rise to the undeniable rise of CO2 was certainly something to consider, but what was not considered, was that half of the increase in temperature recorded since ~1880, had already happened by 1943, during a period when CO2 increased hardly at all. 

More geologically pertinent perhaps, is that the world’s supply of CO2 has declined steadily for the last 150 million years and that, after the last ice sheets withdrew, was lower at 280ppm, than it has ever been in the history of life since the Cambrian explosion. Global warming sceptics noted that during the Pleistocene glaciation, the apparent link between CO2 and temperature was that, as temperature rose or fell, CO2 moved up or down on a similar trajectory, but only after a lag of up to 800 years.  This simple observation was denounced by the IPCC and others, as demonstrating the mendacity of ‘global warming deniers’, who did not care about the world’s health. This observation has now been accepted as mainstream climate doctrine, even by anthropogenic CO2 driven climate change proponents.[1]  Other inconsistencies suggest that the IPCC hypothesis could be wrong; after the last ice age ended, temperatures rose ~8oC, and CO2 100ppm; since 1880, CO2 has risen by 120ppm, but temperature has barely managed 1oC; how does this fit the IPCC hypothesis of climate change?

As geologists, but not ‘real’ climate scientists perhaps (?), we also know that there is never complete consensus on any hypothesis, and new, initially unpopular ideas – such as plate tectonics, can become mainstream, and increasingly supported by new evidence, or can disappear, like miogeosynclines. Scepticism therefore does seem to have a valued place in science - but not, it seems from your editorial, in the science of anthropogenic climate change?

Looking further at the record of CO2, one third of the total increase since ~1880, has taken place since ~1996, during a time of slow-down, or hiatus in global warming – partially obscured by El Nino warming effects. IPCC’s response to this slowdown, was to drop global warming as a catch phrase, and substitute climate change instead. Is it not reasonable to question why these two examples of CO2 increases not affecting temperature changes, seem to have been studiously ignored in the vast amount of current climate change publications? Put another way, is it not more reasonable to ask, if CO2 does not always result in warming, how does it produce climate change?

Scepticism it seems, is never tolerated by consensus holders, so it is no surprise that a Google Search only produces articles that pay homage to the IPCC position. Popularity however – which is all Google search demonstrates, has, like consensus, never been equated with scientific accuracy or probity. Perhaps President Trump’s new EPA will look more carefully at both sides of the debate before committing the world to a potentially futile but very costly attempt to reduce CO2, which will achieve nothing but a reduction of the recent greening of the planet, and the increased crop yields that are measurable benefits of the increasing CO2 content.

If the sceptics are wrong about everything, let us hear them, so we can put them to shame and get the world’s EPA organisations back on track. I therefore call on the GSL, as representing all of its members, to convene an open climate change conference to hear, without rancour and personal innuendo, the present state of the argument. Failing this, I would like to present you and your colleagues some of the data that concern the many sceptics whose voice is rarely heard. This is not about ‘alternative facts’ but about some unpalatable facts.

Your telling quotation, “In an age of universal deceit, telling the truth is a revolutionary act” is proof of nothing, as it could just as easily be applied to much of what the sceptics say about what IPCC puts forward, and also to the gagging order which prevents sceptical views being expressed in print, even after they have turned out to be correct, as is implied in the article referenced above “On paleoclimate time scales, however, the cause-effect direction is reversed: temperature changes cause subsequent CO2/CH4 changes.”  It seems unreasonable to accept that these paleoclimate effects have been vanquished by humanity’s 125ppm contribution to atmospheric CO2.

And as to whether or not speakers, geologists and other attendees will be suitably ‘qualified’ to speak, it might be useful to remember that the politicians who are going to have to implement whatever changes are called for, and journalists who write about them, are mostly unqualified scientifically, yet their combined voices carry more weight than those of the scientists whose work they rely on.

Code buried 06 March 2017

Received 06 MARCH 2017
Published 06 MARCH 2017
From John Heathcote

Sir, Martin Shepley’s Soapbox (Geoscientist 27.02 March 2017) raises some interesting points.  I searched on our website for ‘ethics’ and found nothing.  By diligence I found our Code of Conduct, but not by following any obvious link and it was not found anywhere near the top of the list by the search engine; but at least this alerted me to its title.  The Code is binding on all Fellows, not just CGeols.

I wrote to Professor David Manning when he was President, drawing attention to the difficulty in finding the Code of Conduct on the website, and also to the lack of real guidance on how to deal with certain ethical issues.  (I no longer have his reply to hand, but it was along the lines of ‘noted, but not high priority’.)

We are in exactly the same position in 2017 – the Code remains  buried, and there is no useful guidance on how to tackle unreasonable requests to disguise the scientific truth or even to ignore illegal acts. I still find myself in ethically uncomfortable places, even as recently as this week.

The article also discusses the need not to stray from one’s area of expertise - which the Code also stresses.  However, how is one’s area of expertise proved?  My formal qualification in hydrogeology is a PhD.  This means that I was supervised rather than taught, and did not have to demonstrate to my examiners a grasp of all areas of hydrogeology to be awarded my degree in 1981. It was actually about inorganic hydrochemistry. 

I was able to demonstrate a wider grasp of hydrogeology when I applied for my CGeol in 1993.  I learned about groundwater modelling (which is the capacity in which I worked with Martin Shepley) ‘on the job’. Nowadays I do radioactively contaminated land, also worked out on the job. No-one offers a formal qualification in this, although I teach about it.

I can see the point in having a formal approval system for certain limited areas, but I am wary of trying to approve everything formally.  The scope of geological expertise is too great.  In any event, a formal qualification means only that you passed the exam, not that you have a thorough understanding of the topic.

No amount of formal framework will eliminate the possibility of fraud, which appears to be what Bre-X was about, or errors resulting from unknown unknowns, i.e. a professional being unaware of his ignorance of a topic. UK statute law already covers fraud, although professional ignorance involves the grey area of civil law. To what extent is ignorance negligence?

In the era of ‘post truth’ and also of more litigation, can we please have an accessible Code of Conduct and some guidance on its use?

Hammer horror 01 February 2017

Received 01 FEBRUARY 2017
Published 01 FEBRUARY 2017
From Henk Schalke

Sir, Reading Geoscientist , December/January, 26.11, my particular attention was drawn by the article Tools of the Oldest Profession by Douglas Palmer .  

During fieldwork in the Cantabrian Mountains (N. Spain) I had the bad luck to break my hammer’s hickory shaft. Far away from the possibility of buying a new one (not to mention that my student allowance was gone already!) a local blacksmith offered to repair the hammer by first making 2 extraordinary iron pins and using these to reconnect the shaft to the head. With this hammer all my subsequent fieldwork was done.

In the 1990s that I met, at a geological conference, Giselle d’Ailly - a Dutch painter (once married to the mayor of Amsterdam) who had been asked by our Royal Geological Society here in the Netherlands to paint a portrait of her farther – none other than Willem van Waterschoot van der Gracht, godfather of geology in our country.

Willem van Waterschoot van der Gracht (1873-1943) studied Law, Geology and Mining respectively in Amsterdam and Freiburg (after his stay at the Jesuit College, Stonyhurst, in the UK).

Giselle asked me if it would be a good idea to paint her father in field gear. After some discussion we agreed  - and then she said: “But - I don’t have a hammer, which he always carried with him when doing fieldwork’.  I replied - “Don't worry I will bring you mine!”.

sdgukThe finished portrait was presented to the Geological Survey when their new building was opened by the Royal Prince Clause in 1990 in Haarlem.

You can imagine that we all were very pleased with this portrait, which is shown on the biography of van der Gracht, written by a good friend of mine (picture).

Nowadays the portrait hangs in the building of the Survey in yet another new building in Utrecht, with the real hammer also on display next to it.  (I was asked to donate the hammer so the visiting public could see how a used hammer looks like!).

Dr Henk J W G Schalke,  Oegstgeest.
