Recently : field works (3 to 5 weeks) Congo- Brazzaville 2012, 2015, 2016 (carbonate Neoproterozoic). Degree in geological sciences at the Free University of Brussels (ULB) in 1974, I went to Algeria for two years teaching mining geology at the University of Constantine. Back in Belgium I worked for two years as an expert for the EEC (European Commission), first on the prospecting of Pb and Zn in carbonate environments, then the uranium exploration in Belgium. Then Assistant at ULB, Department of Geology I got the degree of Doctor of Sciences (Geology) in 1985. My thesis, devoted to the study of the Devonian carbonate sedimentology of northern France and southern Belgium, comprised a significant portion of field work whose interpretation and synthesis conducted to the establishment of model of carbonate platforms and ramps with reefal constructions. I then worked for Petrofina SA and shared a little more than two years in Angola as Director of the Research Laboratory of this oil company. The lab included 22 people (micropaleontology, sedimentology, petrophysics). My main activity was to interpret facies reservoirs from drillings in the Cretaceous, sometimes in the Tertiary. I carried out many studies for oil companies operating in this country. I returned to the ULB in 1988 as First Assistant and was appointed Professor in 1990. I carried out various missions for mining companies in Belgium and oil companies abroad and continued research, particularly through projects of the Scientific Research National Funds (FNRS). My research still concerns sedimentology, geochemistry and diagenesis of carbonate rocks which leads me to travel many countries in Europe or outside Europe, North Africa, Papua New Guinea and the USA, to conduct field missions. Since the late 90's, I expanded my field of research in addressing the problem of mass extinctions of organisms from the Upper Devonian series across Euramerica (from North America to Poland) and I also specialized in microbiological and geochemical analyses of ancient carbonate series developing a sustained collaboration with biologists of my university. We are at the origin of a paleoecological model based on the presence of iron-bacterial microfossils, which led me to travel many countries in Europe and North Africa. This model accounts for the red pigmentation of many marble and ornamental stones used in the world. This research also has implications on the emergence of Life from the earliest stages of formation of Earth, as well as in the field of exobiology or extraterrestrial life ... More recently I invested in the study from the Precambrian series of Gabon and Congo. These works with colleagues from BRGM (Orléans) are as much about the academic side (consequences of the appearance of oxygen in the Paleoproterozoic and study of Neoproterozoic glaciations) that the potential applications in reservoir rocks and source rocks of oil (in collaboration with oil companies). Finally I recently established a close collaboration with the Royal Institute of Natural Sciences of Belgium to study the susceptibility magnetic signal from various European Paleozoic series. All these works allowed me to gain a thorough understanding of carbonate rocks (petrology, micropaleontology, geobiology, geochemistry, sequence stratigraphy, diagenesis) as well in Precambrian (2.2 Ga and 0.6 Ga), Paleozoic (from Silurian to Carboniferous) and Mesozoic (Jurassic and Cretaceous) rocks. Recently (2010) I have established a collaboration with Iraqi Kurdistan as part of a government program to boost scientific research in this country. My research led me to publish about 180 papers in international and national journals and presented more than 170 conference papers. I am a holder of eight courses at the ULB (5 mandatory and 3 optional), excursions and field stages, I taught at the third cycle in several French universities and led or co-managed a score of 20 Doctoral (PhD) and Post-doctoral theses and has been the promotor of more than 50 Masters theses.

Germany’s utopian dream of transforming itself into the world’s green powerhouse is collapsing as its political and media establishment is mugged by reality. The country’s climate obsession has turned into one of the country’s biggest political and economic handicaps, making Germany almost ungovernable.

German Scientists Call Recent Sea Level Rise Claims “Fijigate”, …Hyped Up To Generate Money

by Dr. Sebastian Lüning and Prof. Fritz Vahrenholt, November 15, 2017 in  NoTricksZone

After a peak in 2012 the level went down by about 10 cm by mid 2017. It is very much related to natural variations, in sync with the El Ninos (low levels) and La Ninas (high levels).

So what remains of the climate change horror stories in connection to the Fiji Islands? (…)

Reconciling Model-Observation Reconciliations

by Steve McIntyre, November 18, 2017 in ClimateAudit

(…) What does this all mean? Are models consistent with observations or not?  Up to the recent very large El Nino, it seemed that even climate scientists were on the verge of conceding that models were running too hot, but the El Nino has given them a reprieve. After the very large 1998 El Nino, there was about 15 years of apparent “pause”. Will there be a similar pattern after the very large 2017 El Nino?

COP23 – A New Failure

by A Préat, H Masson, D. Godefridi, November 18, 2017

Translation of an article originally published in French on Contrepoints:

We are witnessing a holy alliance between Third World ecologists and big finance, orchestrated by the European Union, under the amused gaze of the American giant who has now taken leave of all this masquerade.

Germany CO2 Reduction Fails Again For 9th Year Running! …Merkel Exposed As Fake Climate Warrior

by P. Gosselin, November 17, 2017 in NotricksZone

Sometimes you have to wonder which are the biggest fraud: Germany’s claim that its cars are clean, or its claim of being a leader in climate protection. Both, it turns out, are very fake and even downright frauds.

While German Chancellor Angela Merkel and German activists like going around and scolding Donald Trump for his “irresponsible” stance on “greenhouse” gas emissions, it is coming to light that Germany’s climate posturing is indeed a total swindle.

Doggerland – The Europe That Was

by National Geography, 2017

The British Isles were once neither British nor isles

Things aren’t always what they seem on the surface. Looking at the area between mainland Europe and the eastern coast of Great Britain, you probably wouldn’t guess it had been anything other than a great expanse of ocean water. But roughly 12,000 years ago, as the last major ice age was reaching its end, the area was very different. Instead of the North Sea, the area was a series of gently sloping hills, marshland, heavily wooded valleys, and swampy lagoons: Doggerland.

Renowned Sea Level Expert: “NO TRACES OF A PRESENT RISE IN SEA LEVEL; On The Contrary: Full Stability”

by Prof. Axel Morner, November 14, 2017 in NoTricksZone

A new paper by renowned Swedish sea level expert Prof. Axel Mörmer published in the International Journal of Earth & Environmental Sciences dumps lots of cold water on the premise that today’s sea level rise is caused by man and is unusual.

Mörner’s paper looks back at the last 500 years of sea level rise and shows that natural variables are the major drivers, and not man-made CO2-driven global warming.


New map of Antarctic geothermal heat suggests Steig & Mann 2009 weren’t measuring ‘global warming’

by Anthony Watts, November 15, 2017 in WUWT

This is quite interesting. Remember the claim in on the front cover of Nature in 2009 by Steig and Mann that Antarctica was warming, thanks to that “special Mannian PCA math sauce” that was applied to air temperature data to smear surface temperature trends over the entire continent? It was dashed by climate skeptics who wrote a paper. It was accepted for publication and disproved (in my opinion) by a team of credible skeptics that wrote a counter-paper. But, there’s an interesting twist thanks to new and surprising data; Steig and Mann may have captured surface air temperature trends in the exact same areas that have been identified as geothermal hot spots.
