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.

66-million-year-old deathbed linked to dinosaur-killing meteor

by U. of California – Berkeley, March 29, 2019 in ScienceDaily

Paleontologists have found a fossil site in North Dakota that contains animals and plants killed and buried within an hour of the meteor impact that killed the dinosaurs 66 million years ago. This is the richest K-T boundary site ever found, incorporating insects, fish, mammals, dinosaurs and plants living at the end of the Cretaceous, mixed with tektites and rock created and scattered by the impact. The find shows that dinosaurs survived until the impact.

EU consumption results in high carbon emissions from tropical deforestation, studies show

by Charles the moderator, March 29, 2019 in WUWT

Chalmers University of Technology

A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies, from Chalmers University of Technology, Sweden, shed new light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.

“In effect, you could say that the EU imports large amounts of deforestation every year. If the EU really wants to achieve its climate goals, it must set harder environmental demands on those who export food to the EU,” says Martin Persson from Chalmers, one of the researchers behind the studies.

The link between production of certain foods and deforestation has been known before. But what Martin Persson and Chalmers colleague Florence Pendrill have now investigated is the extent to which deforestation in the tropics is linked to food production, and then where those foods are eventually consumed. In the first study, they focused on how the expansion of cropland, pastures, and forestry plantations has taken place at the expense of the rainforest.

Emissions sources for deforestation-related carbon dioxide emissions are diverse and vary by region. Emissions embodied in production are shown for each commodity group within each region. A region’s width on the x-axis corresponds to the embodied emissions produced in that region, while the y-axis shows the share of emission attributed to each commodity group within each region, implying that the rectangles within the plot are scaled according to the emissions embodied in each region-commodity combination. The percentages within the rectangles indicate the share of the total embodied emissions; 2.6?gigatonnes of carbon dioxide due to tropical deforestation during the period 2010-2014.

Wildfires Declining In Southern Europe

by P. Homewood, March 28, 2019 in NotaLotofPeopleKnowThat

1. Introduction Fires are an integral component of ecosystem dynamics in European landscapes. However, uncontrolled fires cause large environmental and economic damages, especially in the Mediterranean region. On average, about 65000 fires occur in Europe every year, burning approximately half a million ha of wildland and forest areas; most of the burnt area, over 85%, is in the European Mediterranean region. Trends in number of fires and burnt areas in the Mediterranean region are presented in Fig. 1. Recent analyses of the available data in the European Forest Fire Information System (EFFIS) show that over 95% of the fires in Europe are human-induced. The split of causes shows that most of them are due to misuse of traditional practices of straw burning of shrub-burning to recover areas for cattle feeding. Although European countries have collected information on forest fires since 1970s, the lack of harmonized information at the European level has prevented a holistic approach for forest fire prevention in the Region. The European Forest Fire Information System (EFFIS) has been developed jointly by the European Commission (EC) services (Directorate General Environment and the Joint Research Centre) and the relevant fires services in the countries (forest fires and civil protection services) in response to the needs of European bodies such as the Monitoring and Information Centre of Civil Protection, the European Commission Services and the European Parliament. EFFIS is a comprehensive system covering the full cycle of forest fire management, from forest fire prevention and preparedness to post-fire damage analysis (see Fig. 2). The system is providing information to over 30 countries in the European and Mediterranean regions, and receives detailed information of forest fire events from 22 European countries. It supports forest fire prevention and forest fire fighting in Europe through the provision of timely and reliable information on forest fires.

La transition électrique européenne, une impasse?

by J.P. Schaeken Willemaers, 29 mars 2019 in ScienceClimatEnergie

La transition énergétique est abondamment traitée dans les médias, souvent de manière univoque (ce que d’aucuns appellent le débat confisqué) en ignorant les conséquences socio-économiques. Dans ce papier, nous nous limiterons à sa composante électrique.
Rappelons tout d’abord que la finalité première d’un système électrique est d’assurer l’adéquation entre la production et la consommation d’électricité.


Il va de soi, quoique ce ne soit pas évident pour tout le monde, qu’il faut anticiper les adaptations nécessaires du système avant de procéder à la mise en œuvre du changement. Dans ce processus, l’analyse de l’impact sur la transmission et la distribution d’électricité et sur la continuité des services ainsi que la réalisation des travaux correspondants requis, sont prioritaires. Or aucun gouvernement ayant décidé de réduire drastiquement les émissions de gaz à effet de serre (GES), ne s’est soucié des conséquences de leurs décisions. Ceci explique les déboires des pays qui se sont précipités dans une stratégie de pénétration accélérée de production d’électricité renouvelable intermittente.

Again Reality Goes In Opposite Direction Of Climate Models…”Confidence In Models Correspondingly Low”

by P. Gosselin, March 27, 2019 in NoTricksZone

Real vegetation development in southern Africa takes a very different course than claimed by climate models

By Die kalte Sonne
(German translated by P Gosselin)

Climate models provide answers to all conceivable questions about the future. Political decision-makers are grateful for this information because they can make their plans accordingly.

But are the forecasts derived from models correct at all?

A research team led by Timm Hoffman has now compared the model projections with real vegetation development in southern Africa using historical photos. The sobering result: Nature has mostly developed quite differently than assumed by the models. In contrast to the model assumptions, no significant long-term trend in precipitation could be observed. Vegetation belts, which were supposed to shrink, ended up expanding. Confidence in the models is correspondingly low.

Political planning or even CO2 damage calculations based on the simulations are not possible. Here is the abstract of the work published in the journal Anthropocene in March 2019:

China boosts coal mining capacity despite climate pledges

by M. Xu  & D. Patton, March 26, 2019 in Reuters

BEIJING (Reuters) – China added 194 million tonnes of coal mining capacity in 2018, data from the energy bureau showed on Tuesday, despite vows to eliminate excess capacity in the sector and to reduce fossil fuel consumption.

Total coal mining capacity in the country was at 3.53 billion tonnes per year by the end of 2018, according to a statement from the National Energy Administration (NEA). That compares to 3.34 billion tonnes at the end of 2017.

INFO-SCE: 5% d’augmentation de production d’électricité en Chine : cela fait quoi?

by Science,  Climat et Energie, 27 mars 2019

Selon le dernier rapport de l’IEA, la consommation d’énergie mondiale a augmenté de 2,3% en 2018 ce qui représente la plus forte augmentation des dix dernières années. Le gaz naturel fut le plus consommé et représente 45% de l’augmentation de la consommation totale d’énergie.

Suite à cette augmentation de consommation d’énergie les émissions de CO2 se sont accrues de 1,7% pour atteindre 33,1 Gt en 2018. Près d’un tiers de ces émissions provient des centrales de charbon, surtout celles de la Chine.

Il faut noter que les émissions de CO2 en Chine ont augmenté de 2,5%, ou 230 Mt, pour atteindre 9,5 Gt. Un bond de plus de 5% de la production d’électricité à partir de centrales au charbon a entraîné une augmentation des émissions de 250 Mt, ce qui a plus que compensé l’impact de la baisse de l’utilisation du charbon en dehors du secteur de l’énergie.

Pour comparer…la Belgique émet 115 Mt de CO2.

DONC…l’augmentation des émissions en Chine dues au charbon en 2018 représente plus du double de toutes les émissions de CO2 de la Belgique.

Report : The “New Energy Economy”: An Exercise in Magical Thinking

by Mark P. Mills, March 26, 2019 in ManhattanInstitute

EXECUTIVE SUMMARY

A movement has been growing for decades to replace hydrocarbons, which collectively supply 84% of the world’s energy. It began with the fear that we were running out of oil. That fear has since migrated to the belief that, because of climate change and other environmental concerns, society can no longer tolerate burning oil, natural gas, and coal—all of which have turned out to be abundant.

So far, wind, solar, and batteries—the favored alternatives to hydrocarbons—provide about 2% of the world’s energy and 3% of America’s. Nonetheless, a bold new claim has gained popularity: that we’re on the cusp of a tech-driven energy revolution that not only can, but inevitably will, rapidly replace all hydrocarbons.

This “new energy economy” rests on the belief—a centerpiece of the Green New Deal and other similar proposals both here and in Europe—that the technologies of wind and solar power and battery storage are undergoing the kind of disruption experienced in computing and communications, dramatically lowering costs and increasing efficiency. But this core analogy glosses over profound differences, grounded in physics, between systems that produce energy and those that produce information.

In the world of people, cars, planes, and factories, increases in consumption, speed, or carrying capacity cause hardware to expand, not shrink. The energy needed to move a ton of people, heat a ton of steel or silicon, or grow a ton of food is determined by properties of nature whose boundaries are set by laws of gravity, inertia, friction, mass, and thermodynamics—not clever software.

This paper highlights the physics of energy to illustrate why there is no possibility that the world is undergoing—or can undergo—a near-term transition to a “new energy economy.”

In 2018, U.S. coal exports were the highest in five years

by EIA, March 27, 2019

While U.S. coal consumption has generally declined since its 2008 peak, EIA expects that U.S. coal exports reached 116 million short tons (MMst) in 2018, the highest level in five years, based on foreign trade data collected by the U.S. Census Bureau. Exports of coal from the United States have increased since 2016 as international prices have made it more economic for U.S. producers to sell coal overseas.

In 2018, the United States exported 15% of its coal, and the remaining 85% was sold to end-use markets, primarily power sector and industrial customers. Coal exports have increased during the past two years, driven by increasing international coal demand, and in 2018 accounted for the largest share of total U.S. coal disposition on record. The United States exported 54 MMst of steam coal and 62 MMst of metallurgical coal in 2018, based on export data collected by the U.S. Census Bureau.

Global CO2 Emissions Rose By 1.7% Last Year, As Energy Demand Climbs

by P. Homewood, March 26, 2019 in NotaLotofPeopleKnowThat

Energy demand worldwide grew by 2.3% last year, its fastest pace this decade, an exceptional performance driven by a robust global economy and stronger heating and cooling needs in some regions. Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Gas demand growth was especially strong in the United States and China.

Demand for all fuels increased, with fossil fuels meeting nearly 70% of the growth for the second year running. Solar and wind generation grew at double-digit pace, with solar alone increasing by 31%. Still, that was not fast enough to meet higher electricity demand around the world that also drove up coal use.

As a result, global energy-related CO2 emissions rose by 1.7% to 33 Gigatonnes (Gt) in 2018. Coal use in power generation alone surpassed 10 Gt, accounting for a third of the total increase. Most of that came from a young fleet of coal power plants in developing Asia. The majority of coal-fired generation capacity today is found in Asia, with 12-year-old plants on average, decades short of average lifetimes of around 50 years.

REPORT: GREEN ENERGY ECONOMY IS SIMPLY ‘IMPOSSIBLE’

by Mark P. Mills, March 23, 2019 in GWPF

Hydrocarbons—oil, natural gas, and coal—are the world’s principal energy resource today and will continue to be so in the foreseeable future. Wind turbines, solar arrays, and batteries, meanwhile, constitute a small source of energy, and physics dictates that they will remain so. Meanwhile, there is simply no possibility that the world is undergoing—or can undergo—a near-term transition to a “new energy economy.”

Inconvenient: NASA says a Greenland glacier did an about-face – growing again

by Anthony Watts, March 25, 2019 in WUWT

“…scientists were so shocked to find the change.”

From NASA JPL: Cold Water Currently Slowing Fastest Thinning Greenland Glacier

NASA research shows that Jakobshavn Glacier, which has been Greenland’s fastest-flowing and fastest-thinning glacier for the last 20 years, has made an unexpected about-face. Jakobshavn is now flowing more slowly, thickening, and advancing toward the ocean instead of retreating farther inland. The glacier is still adding to global sea level rise – it continues to lose more ice to the ocean than it gains from snow accumulation – but at a slower rate.

The researchers conclude that the slowdown of this glacier, known in the Greenlandic language as Sermeq Kujalleq, occurred because an ocean current that brings water to the glacier’s ocean face grew much cooler in 2016. Water temperatures in the vicinity of the glacier are now colder than they have been since the mid-1980s.

Nature Unbound III: Holocene climate variability (Part A)

by Javier, April 30, 2017 in ClimateEtc.

First in a two part series on Holocene climate variability.

Summary: Holocene climate is characterized by two initial millennia of fast warming followed by four millennia of higher temperatures and humidity, and a progressively accelerating cooling and drying for the past six millennia. These changes are driven by variations in the obliquity of the Earth’s axis. The four millennia of warmer temperatures are called the Holocene Climatic Optimum which was 1-2°C warmer than the Little Ice Age. This climatic optimum was when global glaciers reached their minimum extent. The Mid-Holocene Transition, caused by orbital variations, brought a change in climatic mode, from solar to oceanic dominated forcing. This transition displaced the climatic equator, ended the African Humid Period and increased El Niño activity.

“Global climate change” does not cause species extinctions

by Paul Berth, March 22, 2019 in ScienceClimatEnergie

Contrary to what the media tries to make you believe, global climate change is not a major cause of species extinction. A recent study published in March 2019 in Frontiers in Ecology and the Environment shows that the major cause of extinction is the introduction of invasive alien species (IAS) into ecosystems. This phenomenon, well known to biologists and confirmed by the IUCN (International Union for the Conservation of Nature), is unfortunately little known to the general public.

Could a transition in paleoclimate reconstruction be underway? More and more, scientists aren’t hiding statements or graphical depictions of the lack of modern warming or the much-warmer Holocene past.

 

A compilation of 35 papers from across the globe indicate that modern climate is not unusual, remarkable or unprecedented, and that large regions of the Earth were as warm or warmer than now when CO2 concentrations were much lower (260 to 350 ppm).

This development continues apace with the trends from the last two years, when 253 non-hockey stick papers were published.

Le “Changement climatique global’ ne cause pas de disparitions d’espèces

by Prof. Paul Berth, 22 mars 2019 in ScienceClimateEnergie

Contrairement à ce que les médias tentent de vous faire croire, le changement climatique global n’est pas une cause majeure de disparition d’espèces. Une récente étude publiée en mars 2019 dans le journal Frontiers in Ecology and the Environment vous le démontre : la cause majeure d’extinction est l’introduction d’espèces exotiques envahissantes (EEE) dans les écosystèmes. Ce phénomène, bien connu des biologistes et confirmé par l’IUCN(Union Internationale pour la Conservation de la Nature), est malheureusement peu connu du grand public.

1. Introduction

En se déplaçant d’un continent à l’autre, l’être humain a toujours emmené avec lui toute une série de plantes et d’animaux qui se retrouvaient ainsi en dehors de leurs limites biogéographiques habituelles. Avec le développement du commerce international ce phénomène ne fait que s’amplifier. Par exemple, à l’intérieur de l’Union Européenne, le nombre d’EEE aurait augmenté de 76% entre 1970 et 2007. Bien que l’impact écologique de la plupart des espèces introduites est inconnu ou semble négligeable, il est démontré que certaines introductions d’espèces ont provoqué des changements substantiels dans des écosystèmes[1]. Ces changements incluent souvent la disparition d’espèces locales[2]. On a d’abord pensé que ces phénomènes d’extinction étaient exagérés et que des espèces locales pouvaient également être à la base d’extinctions[3], et certains auteurs pensent même que les efforts déployés pour contrôler ou éradiquer les espèces étrangères introduites ne seraient pas nécessaires[4]. Cependant, personne n’a jamais vraiment testé si les espèces introduites provoquaient plus ou moins d’extinctions par rapport aux espèces locales ou aux autres causes d’extinctions. Cette question a donc été étudiée par l’équipe de Tim Blackburn (University College London, UK) dans une récente publication de mars 2019[5]. Ils ont pour cela utilisé la base de données des extinctions globales fournie par l’IUCN.

…

Les couleurs renseignent sur les causes des extinctions (“Driver”); par exemple le mauve foncé est employé pour les EEE (“Alien”), les extinctions causées par des espèces locales (“Native”) sont en mauve clair. La catégorie “Neither” comporte les autres causes d’extinction ou alors des causes inconnues (source, Blackburn et al. 2019).

Summit leak reveals EU rift on climate change

by Frédéric Simon, March 21, 2019 in Euractiv

Confidential documents prepared in advance of a two-day EU summit in Brussels have exposed an East-West divide in Europe on climate change, with Germany siding with Poland, Hungary and the Czech Republic in their refusal to commit to climate neutrality by 2050.

The leaked documents, seen by EURACTIV, show the amendments proposed by each country in preparation for the final statement of the leaders summit that opens in Brussels on Thursday (21 March).

And when it comes to climate action, the papers reveal a growing rift between two distinct groups of countries.

On the one hand, France, the Netherlands, Luxembourg, Spain, Portugal, Finland, Sweden and Denmark have all backed a European Commission plan to decarbonise the EU by 2050, linking it specifically to the Paris Agreement objective of keeping global warming below 1.5°C.

A French proposal, for instance, underlines that Europe should strive for climate neutrality “by 2050, in line with the 1.5 degree objective of the Paris Agreement”.

It then calls on EU member states “to prepare a discussion in the European Council in June to define the announcements of the EU at the September Climate Summit in New York”. Both amendments were rejected in the final draft.

On the other hand, Germany, Poland, Hungary and the Czech Republic have refused to specifically link EU climate action with the 1.5°C objective. They also oppose any time-bound commitment to the EU’s climate neutrality objective, deleting any reference to 2050 for reaching that goal.

Bjørn Lomborg on ‘climate strikes’ – normalization of extreme language reflects decades of climate-change alarmism

by Anthony Watts, March 19, 2019 in WUWT

It is little wonder that kids are scared when grown-ups paint such a horrific picture of global warming.

For starters, leading politicians and much of the media have prioritized climate change over other issues facing the planet. Last September, United Nations Secretary-General António Guterres described climate change as a “direct existential threat” that may become a “runaway” problem. Just last month, The New York Times ran a front-page commentary on the issue with the headline “Time to Panic.” And some prominent politicians, as well as many activists, have taken the latest report from the United Nations Intergovernmental Panel on Climate Change (IPCC) to suggest the world will come to an end in just 12 years.

The Green New Deal’s Weak Chain Of Logic

by Daniel G. Jones, March 18, 2019 in ClimateChangeDispatch

Reagan observed: “It isn’t so much that liberals are ignorant. It’s just that they know so many things that aren’t so.”

So it is with the Green New Deal. Most liberals regard it as a simple proposition: Global warming is a really big problem, and it’s our fault, so let’s fix it.

But closer analysis reveals that the argument for the Green New Deal rests upon a long chain of interdependent assertions, every one of which must be believed for the problem to be of sufficient peril to warrant their drastic solution.

Here are links in their chain of logic. If you doubt the truth of any single step, you must discard the entire argument.
