Professor William R. Church, Western University

                    Professor Emeritus of Geotectonics in the Department of Earth Sciences. Retired June 30th, 2002.  Born and bred in the the coal mining community of Thomastown (Coedely colliery) just south of Tonyrefail  at the head of the Ely Valley in South Wales. Iechyd da i gyd!

.                  Places of importance in my youth -
  the Vale of Glamorgan and the Bristol Channel from the Garth Mountain,
 the (c. 1830) Watkins' family home 'Warren House' in  Pentyrch, north of Cardiff;  Cwmlai elementary School (
a Child's Xmas in Wales ) ;  Tonyrefail Grammar School where the chemistry teacher Mr Gran Lloyd excited my interest in Chemistry, and the Physics teacher 'old' Gabe made sure I was thoroughly grounded in Physics and Calculus; and Ballyshannon in Donegal, Eire, where I learnt to combine my love of the outdoors with the study of 'rocks', and which eventually led me to Baie Verte in Newfoundland in search of eclogites that would link the Fleur de Lys psammites of the North American Appalachians to the Lough Derg psammites of the Irish Caledonides on the other side of the Atlantic, studies that eventually led to the recognition that the Appalachians and Caledonides represented a once continuous plate tectonic system wherein the eclogites represented subducted continental material dragged to depth beneath a west-facing obducting oceanic arc represented by the ophiolites of the Baie Verte region and the Bay of Islands of Western Newfoundland.

     The oldest geological map in the world  - geological map of an old gold mine exploited in Pharaonic times during the reign of King Seti I; Nineteenth Dynasty, 1350-1205 B.C. The map is known as the Turin Papyrus and shows the stone quarries and gold mines in Wadi Hammamat near Naqada (Nubt = gold town).
     Jabal Zebara --  my favourite wilderness area.
     Ciorneva         - in the French/Italian Alps (1974; also very quiet!).
     Montmatre - rue de Mont-Cenis  - Utrillo.
    
Relics from the First World War - and the words from father to father.
     Xmas at the Western Front somewhere in France - waifs and war, dolls and little mothers....
     The history of Thomastown - a coal mining community in the Ely Valley of South Wales.
     The view towards Llantrisant viewed from the west slope of the Glyn mountain The distant dot is the "Billy Wynt"  marking the high point of the southern scarp of the South Wales coal field (north-dipping Carboniferous Pennant Sandstone limb of the Hercynian South Wales syncline) . The "Billy Wynt" is the remains of a 13th Century windmill destroyed during a battle in the Middle Ages, but still shown as the site of a windmill on Bowen's 1729 map of South Wales. The nearby Llantrisant castle, also built in the 13th Century, was held for Edward I by the Norman de Clare family.   The adjacent common land at Llantrisant, consisting of some 298 acres, was granted along with charter status to the Freemen of  Llantrisant, supposedly in recognition of the participation of Llantrisant longbowmen in the Battle of Crecy in 1346 (not something I mention in the presence of my wife! -  at the battle of Agincourt the French threatened to remove the 2 string fingers of all Welsh archers who were captured.)
    
The Ely valley as seen from Llantrisant  - the triangular 'tip' (mine waste dump) in the far left distance was fed by the coal mine in Coedely.
    
The only decent way to travel  -  day trip by train to the seaside at Porthcawl.
     Rhondda Grey - a poem by Max Boyce.
     The Glyncorrwg yewtree - according to Lewis'  Topographical Dictionary of Wales, 1833, it was 'thirty feet four inches in girth' even at this time.
     Galena-bearing Triassic sandstone - unconformable on Carboniferous Limestone, near Creigiau - my first home-made 'cat's whiskers' radio was operated with galena (a natural transistor) from these rocks.  ("Some (me) couldn't afford commercially available crystal detectors and made their own with a chunk of galena crystal and a cat's whisker. Galena is the name for lead sulfide which is the principal ore of lead. The cat's whisker was actually a very fine wire. The procedure was to made a good connection to the galena for one terminal and to probe around with the cat's whisker for a 'sweet spot' for the other terminal" - http://www.jmargolin.com/history/trans.htm )
     
Welsh diamonds - concretionary  ironstones in the Welsh Coal Measures commonly contain geodes in which grow euhedral quartz grains and acicular sprays of millerite (NiS).
     
South Wales as a wine producer?  (My grandmother Margaret Jones was born here at Tynant, Groes-faen, and her parents Sam and Ann are buried there in the village.)
      Field location in the wildest Newfoundland bush from where I proposed to my wife -  she says that I was probably thinking that marriage couldn't possibly be any worse!
     
Rock carving, Fleur de Lys, Newfoundland - image of an old (how old?) schooner carved in soapstone, Fleur de Lys, Burlington Peninsula, Newfoundland.
     
The flower of Fleur de Lys -  small aboriginal soapstone quarry at Fleur de Lys.
     
The heyday of Newfoundland cod fishing.
     
Detrital chromite  - the discovery of grains of detrital chromite in Ordovician-age sandstones was one of the primary observations leading to the interpretation of Appalachian ultramafic-mafic sequences as 'oceanic' crust.
     
The last of the summer wine! - From Tonyrefail to South Australia, 1950's to 2008

            Cycling adventures:
Cycling in France and Spain, plus  some sites on the Geology of the Catalan/Pyrenean region of Spain.
Are you young, fit, and enthusiastic?  Could you cycle1200 km in 89 hours - read Harriet Fells account of her participation in the Paris - Brest - Paris ride.

Tour de France 2004 - The cyclist with the with the yellow jersey is the infamous Lance Armstrong.
                PROFESSIONAL EXPERIENCE
    Geology of  Europe, South and North America, India, Morocco, Egypt, Saudi Arabia, Sudan, and Russia, and the evolution of Paleozoic and Pre-Cambrian ocean basins.
    Currently interested in: 1)  Geographic Information Systems from the point of view of "Earth Systems Science"; 2) all things geological, geochemical, and geophysical; 3) the introduction of GIS concepts into undergraduate field mapping courses, and the development of undergraduate/graduate geology excursion web sites, e.g.  http://instruct.uwo.ca/earth-sci/fieldlog/cargo/indexcargo.htm   In particular,  the geology of the Sudbury region, the Highland Border Series of Scotland, the geology of Cuba;  dynamic topography during the Archean;  the chemistry of sea water; a better level of competency in Spanish in order to take another student field trip to Cuba and/or Mexico.

SOCIETY OF ECONOMIC GEOLOGISTS, UWO STUDENT CHAPTER SHORT COURSE ON THE GEOLOGY AND MINERAL DEPOSITS OF NUNAVUT TERRITORY, FEBRUARY 2000

 KIMBERLITE FIELDS OF NUNAVUT BY JOHN ARMSTRONG

DOWBANK GOLD DEPOSITS, NUNAVUT BY BRIAN ALEXANDER

        GLOBAL WARMING, KYOTO, etc - who to believe?
The position of the Geological Association of Canada (GAC) versus that of the Canadian Society of Petroleum Geologists (CSPG).
GAC - (i) that climate changes, naturally;
CSPG - Global climate change is a natural and continual process on Earth.  Climate changes similar to and much more severe than those happening today have occurred repeatedly throughout historic and geologic time, as the result of many natural factors.
CSPG - 1. Global climate change has been a constant throughout the history of the Earth, driven by a variety of global and astronomical natural factors.  The variability of and interactions among these factors are the subjects of active research, but are still very poorly understood by climate scientists.  Observations of past climatic variations show much better correlation with astronomical variables such as solar activity and orbital changes than they do with atmospheric CO2 levels.
GAC - (ii) that greenhouse gas emissions have made a positive contribution to warming of the size of current increases, but the buffering mechanisms need to be better understood before we can tell just how strong an effect the emissions have;
CSPG - Climate science is only beginning to understand these factors and their interactions.  There is no significant evidence, and certainly no "scientific consensus", that greenhouse gases produced by humans are driving any unusual climate changes.
CSPG - 2. Since the beginning of the 20th century, atmospheric CO2 has risen with accelerated production of CO2 by human activities.  However, using the best attempts to remove biases from temperature data, there is not a good correlation between atmospheric CO2 and global temperatures.
GAC - (iii) that, while we get a better grip on such climate modelling, a cautionary approach should be taken, including effort to reduce greenhouse gas emissions;
CSPG - Mankind's greatest efforts to reduce production of carbon dioxide, a natural component of the atmosphere essential to all life, will not significantly affect future climate change.  The climate will change naturally, and mankind must adapt, as all life has done throughout the Earth's history. We should not be distracted from the worthwhile goals of using all resources wisely, and of reducing our production of polluting chemicals that are truly harmful to life on Earth. (see Quirks and Quarks below)
CSPG - 3. Global circulation models attempt to represent climatic influences with numerical equations, and are used to predict future climate variations.  However, they are hampered by our poor understanding of the relationships and feedback loops among many of the key variables.  GCM predictions of warming trends through the 21st century have decreased systematically as the models have become more sophisticated.
CSPG - 4. These observations suggest that global climate change is a natural and fundamental part of earth history, and that the effects of human activities on global climate are no more than a poorly-understood fourth-order factor.
GAC - (iv) that geoscience has lots to offer in predicting the impact of global warming;
CSPG - ?
GAC - (v) that smart geoscience has many applications in our adaptation to current warming and its consequences.

           Recent 2005 EPICA core data discussion

           Everybody wins, everybody loses!!  Antarctic core data shows that periods of CO2 increase (to c. 290 ppm/v) and consequent global warming are kick-started with the termination of the orbital cooling cycle when CO2 values have decreased to values of c. 190 ppm/v.  The current CO2 values of 380 ppm/v are therefore well above the normal CO2 concentration at the present stage of the orbital cycle.

          During the cooling part of the cycle CO2 is progressivly dissolved in ocean water; the relatively rapid release of CO2 once the asymmetric warming part of the cycle commences is perhaps related to loss of solubility of the CO2 and the physical displacement of CO2 rich deep ocean waters towards the surface.

"Re #116:
as the graphs of Jouzel are too coarse, I have put the Vostok trends of the Eocene period on the net here, and added a (rough) trend for the temperature based on the delta-D correction. The corrected temperature trend indeed stays a longer time at higher levels, but goes faster down and still is near its minimum, before CO2 starts to decrease. While the overall correlation temperature - CO2 is higher with this correction, the correlation temperature - CH4 gets much worse…"

Welcome to climate change in Canada - http://adaptation.nrcan.gc.ca/posters/cc_en.asp

"A natural system known as the "greenhouse effect" regulates the temperature on earth. Human activities have the potential to disrupt the balance of this system. As human societies adopt increasingly sophisticated and mechanized lifestyles, the amounts of heat-trapping gases in the atmosphere have been increased. By increasing the amount of   these gases, humankind has enhanced the warming capability of the natural greenhouse effect. It is the human-induced enhanced greenhouse effect that causes environmental  concern. It has the potential to warm the planet at a rate that has never been experienced  in human history."
"  The increase in temperature was not constant, but rather consisted of warming and cooling cycles at intervals of several decades."

Broecker, W.S.  2001.  Glaciers That Speak in Tongues and other tales of global warming.  Natural History 110 (8): 60-69.

     A Conservative commentary from the Center for the Study of Carbon Dioxide and Global Change:

   The Little Ice Age, a period (Broecker)  refers to as "a cold episode that ran from about 1300 to 1860."
      .....roughly half the overall warming since 1860 occurred before carbon dioxide (CO2) emissions from human activities had reached significant levels.
    ......The most recent of such (warm) episodes, of course, would be the Medieval Warm Period (another climatic phenomenon the climate alarmists are wroth to recognize) and before that the Roman Warm Period.
  ..... the concluding words of Broecker, "we can state with some confidence that natural Holocene temperature fluctuations have been on the same scale as the human-caused effects estimated to result from greenhouse gases."  Hence, as he continues, "we cannot assume that in the absence of human intervention, earth's temperatures would have remained stable." Yes, there is absolutely no way for proponents of CO2 emission regulations to prove  their case, especially when all indications suggest that nothing climatically out of the ordinary is even on the verge of happening, or, as climate alarmists are irrationally wont to claim, has already happened.  But "does this mean we can all sit back, do nothing, and wait for the results to roll in?"  Broecker answers his rhetorical question with a Certainly not.  We, however, say Yes, especially with respect to committing the nations  of the earth to mandatory CO2 emissions reductions.
    With respect to this difference of opinions, it is important to note that they are just that, opinions.  Broecker bases his on a belief in the adequacy of current climate models.  We base ours on a belief in their inadequacy, as well as the weight of evidence discussed above, plus the likelihood we will need all the atmospheric CO2 we can muster in the years ahead to prevent the catastrophic shortages of food and water that will otherwise likely materialize (see our Editorials of 1 October 1999, 1 February 2000, 15 November 2000, 21 February 2001, 2 May 2001, 13 June 2001).
    Although we thus disagree with Broecker on what he thinks we should be doing about the ongoing rise in the air's CO2 content, we have not the slightest doubt about the sincerity of his expressed belief.  And we have nothing but the greatest admiration for his scientific insight and integrity.  If everyone on both sides of the issue were as forthcoming as he is with respect to these matters, it would be a far, far better world.

   Phanerozoic climatic indicators and reconstructed pCO2 levels, Figure 1.

   Abstract: "...analyze the reconstructed seawater paleotemperature record for the Phanerozoic ... , and compare it with the variable cosmic ray flux (CRF) reaching Earth and with the reconstructed partial pressure of atmospheric CO2 (pCO2).  ....at least 66% of the variance in the paleotemperature trend could be attributed to CRF variations likely due to solar system passages through the spiral arms of the galaxy. ...We propose a tentative upper limit to the long-term "equilibrium" warming effect of CO2, one which is potentialy lower than that based on general circulation models."

     "the global climate possesses a stabilizing negative feedback. A likely condidate for such a feedback is cloud cover (Lindzen, 1997; Ou, 2001). If so, it would imply that the water cycle is the thermostat of climate dynamics, acting both as a positive (water vapor) and negative (clouds) feedback, with the carbon cycle "piggybacking" on, and being modified by the water cycle (Neumani et al, 2002; Lovett, 3002; Lee and Veizer, 2003)."

        The other concern - Pollution and Health:

         November 23, 2002 on Quirks & Quarks: When Smoke Ran Like Water:

         Over the past few decades, you could say that we've made enormous gains in linking environmental pollution to human health problems. We've taken the lead out of gasoline and paint;  we've restricted or banned smoking in airplanes  and most public buildings; we've put catalytic converters on cars; we've taken asbestos out of our  walls. But according to Dr. Devra Davis,  governments and industry have consistently ignored or even discredited the link between  pollution and health. In her new book, she documents a long history of "death by  contaminants", and calls for a new war against environmental deception.
