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.

China plans 226 GW of new coal power projects: Environmental groups

by Reuters, Sep. 19, 2019


SHANGHAI (REUTERS) – China’s total planned coal-fired power projects now stand at 226.2 gigawatts (GW), the highest in the world and more than twice the amount of new capacity on the books in India, according to data published by environmental groups on Thursday (Sept 19).

The projects approved by China amount to nearly 40 per cent of the world’s total planned coal-fired power plants, according to the Global Coal Exit List database run by German environmental organisation Urgewald and 30 other partner organisations.

The new China projects would be more than Germany’s existing installed power capacity of around 200 GW by the end of 2018.

The environmental groups said in a press release on Thursday that worldwide 400 of the 746 companies in their database were still planning to expand their coal operations.

The companies include miners and power generators, and account for 89 per cent of the world’s thermal coal production and nearly 87 per cent of the world’s installed coal-fired power capacity. Of the total, 161 are Chinese.

Global decarbonisation efforts ‘stall’, pushing climate goals out of reach

by Matt  Mace, Sep. 19, 2019 in Euractiv


Global decarbonisation efforts will need to be seven times greater if the world is to stand a fair chance of limiting global warming to 1.5C, according to a new PwC report which found decarbonisation has slowed to its lowest level since 2011. EURACTIV’s media partner edie.net reports.

PwC UK’s latest Low Carbon Economy Index (LCEI), published today (19 September), found that reaching the Paris Agreement’s 2C limit for global warming would require the global economy to reduce its carbon intensity by 7.5% every year up to 2100. The report notes that this is five times faster than the current decarbonisation rate of 1.6% – less than half the decarbonisation rate witnessed in 2015 (of 3.3%), when the Paris Agreement was introduced.

In order to meet the more ambitious target of the Paris Agreement – limiting global warming to 1.5C which has been requested by the Intergovernmental Panel on Climate Change (IPCC’s) special report – decarbonisation rates must reach 11.3% annually. That is seven times greater than the current rate, which has slowed to its lowest level since 2011.

Doomsdays that didn’t happen: Think tank compiles decades’ worth of dire climate predictions

Rep. Alexandria Ocasio-Cortez recently suggested Miami would disappear in “a few years” due to climate change. The United Nations is convening a “Climate Action Summit” next week. And climate activist Greta Thunberg is on Capitol Hill this week telling lawmakers they must act soon.

But while data from NASA and other top research agencies confirms global temperatures are indeed rising, a newly compiled retrospective indicates the doomsday rhetoric is perhaps more overheated.

The conservative-leaning Competitive Enterprise Institute has put together a lengthy compilation of apocalyptic predictions dating back decades that did not come to pass, timed as Democratic presidential candidates and climate activists refocus attention on the issue.

The dire predictions, often repeated in the media, warned of a variety of impending disasters – famine, drought, an ice age, and even disappearing nations – if the world failed to act on climate change.

An Associated Press headline from 1989 read “Rising seas could obliterate nations: U.N. officials.” The article detailed a U.N. environmental official warning that entire nations would be eliminated if the world failed to reverse warming by 2000.

Then there were the fears that the world would experience a never-ending “cooling trend in the Northern Hemisphere.” That claim came from an “international team of specialists” cited by The New York Times in 1978.

German Climatologist Werner Kirstein Unloads: “IPCC Is To Deceive People”…Calls Michael Mann’s Chart “A Fake”

by P. Gosselin, Sep.17, 2019  in NoTricksZone


German climate scientist Professor Werner Kirstein was interviewed by alternative media outlet NuoViso,  and since the video was released early this month on Youtube, it has been viewed over 130,000, times.

Politics commissioning reports for money

In the interview Professor Kirstein tells moderator Robert Stein that CO2 emissions have no effect on the climate and that “politicians commission climate scientists to produce expert reports for money.”

“Public is being deceived”

Prof. Kirstein talks about the “conscious deception” of the public and how all research projects and publications by “climate scientists” only have the goal of confirming “man-made climate change” and that different scientific views are not welcome.

According to Kirstein, the public is being deceived with the false information and that the aim of politics is to find a way to collect further taxes and to collect levies.

“We currently see this with the climate tax, which is to be introduced soon,” Kirstein says.

Climate Hysteria: Rising Number Of Children Treated For ‘Eco-Anxiety’

by P. Homewood, Sep. 16, 2019 in NotaLotofPeopleKnowThat


Protests by groups such as Extinction Rebellion, the recent fires in the Amazon and apocalyptic warnings by the teenage activist Greta Thunberg have prompted a “tsunami” of young people seeking help.

A group of psychologists working with the University of Bath says it is receiving a growing volume of enquiries from teachers, doctors and therapists unable to cope.

The Climate Psychology Alliance (CPA) told The Daily Telegraph some children complaining of eco-anxiety have even been given psychiatric drugs.

Une brève histoire du climat

by Egbert Egberts, 12 septembre 2019, in ScienceClimatEnergie


ATTENTION ! Cet article pourrait permettre d’économiser des milliards d’euros…

Après un été avec des températures au-dessus de 40°C, les prédictions de catastrophes sont allé bon train. “Si on ne fait rien, …” Nos politiques, pressés par une (petite) partie de leur électorat, proposent des mesures à faire pâlir les contribuables impuissants que nous sommes. Pensez aux mille milliards d’euros que veut dépenser la nouvelle présidente de la Commission européenne pour juguler le climat et limiter le réchauffement climatique.

Dans l’ensemble, on traite cette question sans aucun regard en arrière. Comme si le changement climatique était un phénomène nouveau, qui nous est tombé dessus parce qu’on roule en voiture. Cependant, il ne s’agit pas d’un phénomène nouveau et le monde francophone est particulièrement bien placé pour le savoir. Nous possédons un livre fouillé sur l’évolution du climat entre l’an 58 avant Jésus-Christ et 1842 A. D., un véritable trésor ! Pourquoi ? Parce que cela nous donne le recul indispensable pour mieux comprendre ce qui nous arrive aujourd’hui. En 1845, Joseph-Jean-Nicolas Fuster a publié son livre de 503 pages Des changements dans le climat de la France : histoire de ses révolutions météorologiques aux éditions Capelle à Paris.[1] Son livre nous résume ainsi l’évolution du climat pendant presque deux millénaires.

LONG-TERM US DROUGHT AND PRECIPITATION TRENDS

by R. McKitrick & J. Christy, Sep. 14, 2019 in WUWT


Ross McKitrick and John Christy have published a new paper in the Journal of Hydrology.

Abstract : We estimate trends in US regional precipitation on multiple time spans and scales relevant to the detection of changes in climatic regimes. A large literature has shown that trend estimation in hydrological series may be affected by long-term persistence (LTP) and selection of sample length. We show that 2000-year proxy-based reconstructions of the Palmer Modified Drought Index for the US Southeast (SE) and Pacific Coast (PC) regions exhibit LTP and reveal post- 1900 changes to be within the range of longer-term natural fluctuations. We also use a new data base of daily precipitation records for 20 locations (10 PC and 10 SE) extending back in many cases to the 1870s. Over the 1901–2017 interval upward trends in some measures of average and extreme precipitation appear, but they are not consistently significant and in the full records back to 1872 they largely disappear. They also disappear or reverse in the post-1978 portion of the data set, which is inconsistent with them being responses to enhanced greenhouse gas forcing. We conclude that natural variability is likely the dominant driver of historical changes in precipitation and hence drought dynamics in the US SE and PC.

Important news from the world’s top meteorologist

by Larry Kummer, Editor, Sep.14, 2019 in WUWT


Summary: After years of tacit cooperation with climate activists, the first major climate agency may have begun to turn against their misuse of climate science. If so, this would be a big event in the climate debate. As seen in this interview with the head of the WMO. He has much to say that we need to hear.

Scientists are turning against climate activists and their scare tactics.

but the debate is

Greta, Germany & Green Energy

by J. Curry, Sep. 10, 2019 in BigPictureNews


Anyone who still thinks green/renewable energy is the answer is invited to click over to a web page that monitors Germany’s celebrated Energy Transition (English translation here). The most recent six-month update has just been published. Despite a multi-billion-euro price tag, Germany’s attempts to ditch fossil fuels isn’t going well. At all.

Only six of the transition’s 14 goals (43%) appear achievable by 2020. Here are the two absolutely critical data points:

#1 – Germany’s CO2 emissions reduction targets won’t be met.

#2 – Its previously robust electricity grid is now vulnerable and insecure.

The story of Germany’s energy transition boils down to this: Something that used to work well has been deliberately broken, undermined, degraded, and crippled. A ton of money has been spent. To make things worse.

Over at Forbes, Michael Shellenberger discusses how this latest report card is being covered in the German press. In his words:


EXTREME COLD RIPS THOUGH NEW ZEALAND’S SOUTH ISLAND — HELICOPTERS FLOWN-IN TO PROTECT THE HARVESTS

by Cap Allon, Sep. 10, 2019 in Electroverse


Frost-fighting efforts have shifted into overdrive on New Zealand’s South Island as a brutal Antarctic blast rips through the region — the first blast of many, according to NIWA forecasts.

Otago, a southeastern region of NZ’s South Island, is home to the buds of millions of dollars worth of stone-fruit. Forecasters say temperatures in central Otago plummeted to a bruising -5C (23F) on Tues morning, Sept 10.

Sprinklers were turned-on so as to deliberately encase the tender fruit in a protective clear-ice casing — an age-old method of frost-fighting. While helicopters and wind machines were also drafted-in to blow warm air over the orchards.

“It’s all hands on deck,” said Tim Jones, chief executive of 45 South Orchard and Packhouse in Cromwell, who expects the cold to stick around for at least another month.

“NIWA has got some news out there that this could be a challenging spring,” Jones added.

New Zealand has a higher-than-usual risk of sharp cold snaps and unsettled weather during the first half of the season, according to the National Institute of Water and Atmospheric Research (NIWA).

rare sudden stratospheric warming (SSW) event is occurring 30-50 km above Antarctica which is already leading to unusual and extreme weather in parts of the Southern Hemisphere.

 

Nearly Half Of 53 Tidal Gauges Show Negative Sea-Level Rise

by K. Richard, Sep. 10, 2010 in ClimateChangeDispatch


The West Coast of North America has 20 long-term (90+ years) tide gauges measuring relative sea-level changes.

The East Coast has 33. Of the 53 total tide gauges, 45% (24) are negatively accelerating, 14 document falling sea levels, and just 11 have sea levels rising more than 3 mm/yr.

A cooling/non-warming North America

A few months ago, Gan et al. (2019) reported that the North American continent as a whole (180-0°, 15-60°N) “is one of the major cooling centers” in the Northern Hemisphere, with temperatures dropping after 1998 and no significant net change since the early 1980s apparent.

‘Alarmism Enforcement’ On Hurricanes And Global Warming

by J. Curry, Sep; 9, 2019 in ClimateChangeDispatch


I used to be concerned about ‘consensus enforcement’ on the topic of climate change.  Now I am concerned about ‘alarmism enforcement.’

Ever since Hurricane Katrina in 2005, any hurricane causing catastrophic damage has been seized upon by climate alarmists as evidence of the horrors of global warming.

As if the record-holding hurricanes from the 1920s through the 1950s never happened.

The catastrophic damage to the Bahamas from Hurricane Dorian is no different.  The ‘official’ statement from the alarmist contingent of climate scientists appears to be this article in the Guardian, by Mann and Dessler:

Unfortunately for the alarmists, there are several factors that are getting in the way of the public promotion of the Mann/Dessler narrative:

Alabama-gate:  President Trump’s insistence on defending his erroneous statements about the forecasts for Dorian impacting Alabama.  A good article summarizing all this was co-authored by one of my former students at Georgia Tech, Brandon Miller [link].

After the Alabama National Weather Service office made a statement that Alabama was not at risk from Dorian, NOAA issued a statement defending President Trump  [link].

A WaPo article describes this latest development [link], and the subsequent outrage among scientists and NOAA employees (past and present.

This whole situation is taking the oxygen out of the room in terms of discussions regarding Dorian and global warming.  Gotta wonder if this was the strategy?

UK: New “Beast from the East” could cause one of the coldest winters in three decades

by Charles the moderator, Sep. 9, 2019 in WUWT


The UK could be set to experience one of the coldest winters in three decades, scientists have warned.

Meteorologists say an even more extreme version of the “Beast from the East” could see parts of the country hit with blizzard-like conditions throughout much of January and February next year.

Using ground-breaking analysis of sea temperatures and air pressures, scientists have been able to predict one of the longest-range UK weather forecasts ever recorded – according to The Sunday Times.

Mark Saunders, professor of climate prediction at University College London (UCL), said: “This would rank the 2020 January-February central England temperature as the coldest winter since 2013.”

THICK ARCTIC ICE STOPS YET ANOTHER SHIP OF CLIMATE CHANGE DOCUMENTARY FILMMAKERS

by Cap Allon, Sep. 9, 2019 in Electroverse


The MS MALMO is the latest in a long list of ships to have gotten stuck in surprisingly thick Arctic sea ice this year.

The Swedish vessel, built in 1943 and refurbished in 2014, was on an “Arctic tour” with the noble mission of ferrying a team of Climate Change documentary filmmakers to the front line. The teams intention was to capture some of the catastrophic ice melt being reported by the worlds media — ice melt which it would appear still refuses to manifest despite decades of furious willing from the UN & IPCC.

The MS MALMO came to a grinding halt on Sep 3 off Longyearbyen, the Svalbard Archipelago, halfway between Norway and the North Pole, when it encountered impenetrably thick ice:

Climate Warriors Stuck In Arctic Ice (That All Melted Years Ago!)

by P. Homewood, Sep. 8, 2019 in NotaLotofPeopleKnowThat


Arctic tours ship MS MALMO with 16 passengers on board got stuck in ice on Sep 3 off Longyearbyen, Svalbard Archipelago, halfway between Norway and North Pole. The ship is on Arctic tour with Climate Change documentary film team, and tourists, concerned with Climate Change and melting Arctic ice. All 16 Climate Change warriors were evacuated by helicopter in challenging conditions, all are safe. 7 crew remains on board, waiting for Coast Guard ship assistance.
Something is very wrong with Arctic ice, instead of melting as ordered by UN/IPCC, it captured the ship with Climate Change Warriors.
