Small increase in EU’s total greenhouse gas emissions in 2017, with transport emissions up for the fourth consecutive year

by European Environment Agency, May 29, 2019


Total greenhouse gas emissions in the European Union (EU) increased by 0.7 % in 2017, according to latest official data published today by the European Environment Agency (EEA). Less coal was used to produce heat and electricity but this was offset by higher industrial and transport emissions, the latter increasing for the fourth consecutive year.

According to the EEA’s Annual European Union greenhouse gas inventory 1990-2017 and inventory report 2019, total greenhouse gas emissions (including international aviation) rose by 0.7 % in 2017 compared with 2016. These official data confirm the preliminary estimates published by the EEA in October 2018. From 1990 to 2017, the EU reduced its net greenhouse gas emissions by 21.7 %. The EU is therefore still exceeding its 20 % reduction target set for 2020.

Cycles of Rapid Climate Warming

by Jim Steele, May 28, 2018 in WUWT


The globally averaged temperature rose 1.5°F from 1880 to today. Various narratives suggest the rise since 1950 was driven by increasing concentrations of CO2. The rising temperature before 1950 was considered natural. Since 1990, Arctic temperatures rose 2 to 3 times faster than the global average. So, are rapidly rising Arctic temperatures evidence of an impending climate crisis?

Astute students of climate history recall rapid Arctic warming has happened often and naturally. During the last Ice Age when CO2 concentrations were just half of today’s, 25 abrupt warming events happened. Arctic temperatures rose 9°F, and sometimes as much as 14°F in just 40 years. These rapid warming episodes are now called Dansgaard–Oeschger events (D-O events) in honor of the researchers who first detected them in Greenland’s ice cores. These D-O episodes affected global climate, changed ocean currents along California’s coast and altered the range of European forests.

What caused such abrupt warming? Basic physics dismisses changes in greenhouse gases or solar insolation because neither radiative effect induces such rapid warming. The most reasonable explanation suggests episodes of ventilating heat, that had accumulated in the Arctic Ocean, rapidly warmed the air.

China Threaten To Ban Export Of Rare Earths

by P. Homewood, May 29, 2019 in NotaLotofPeopleKnowThat


China has hinted that a trade war with the U.S. could lead to real war with a coded warning as it threatens to stop exporting essential ‘rare earth’ minerals.

A commentary in People’s Daily, the mouthpiece of China‘s ruling Communist Party, today said ‘Don’t say we didn’t warn you!’ – which is a diplomatic term usually reserved by Beijing to signal the start of an armed warfare.

China yesterday said it is ‘seriously considering’ restricting exports to the United States of rare earths, 17 chemical elements used in hospital scanners, nuclear power stations and LED lights.

China accounted for 80 per cent of rare earth imports between 2014 and 2017 to the United States.

 

Roy Spencer: Why so many tornadoes this year? It’s not what AOC, Bernie Sanders (or maybe even you) think

by Charles the moderator, May 29, 2019 in WUWT


By Roy Spencer | Fox News

Progressive politicians like Al Gore, Sen. Bernie Sanders, I-Vt., and Rep. Alexandria Ocasio-Cortez, D.N.Y., don’t hesitate to blame any kind of severe weather – even if it is decreasing over time – on global warming.

With the devastating Dayton, Ohio tornadoes fresh on our minds, it is useful to examine exactly why (modest) global warming has produced fewer – not more – of such events.

The simple answer is that tornado formation requires unusually cool air.

Very few thunderstorms produce tornadoes. In the hot and humid tropics, they are virtually unheard of. The reason why is that (unlike hurricanes) tornadoes require strong wind shear, which means wind speed increasing and changing direction with height in the lower atmosphere.

These conditions exist only when a cool air mass collides with a warm air mass. And the perfect conditions for this have existed this year as winter has refused to lose its grip on the western United States. So far for the month of May 2019, the average temperature across the U.S. is close to 2 degrees Fahrenheit below normal.

Les pays du G20 ont augmenté leur consommation énergétique et leurs émissions de CO2 en 2018

by Eva Gomez, 28 mai 2018 in EnvironnementMagazine


Ce mardi 28 mai, le bureau d’études Enerdata publie son bilan énergétique mondial pour l’année 2018. Celui-ci fait part d’une hausse et de nouveaux records de consommation d’énergie et d’émissions de CO2.

En 2018, les pays du G20 ont vu leur consommation d’énergie augmenter de 2,1% et leurs émissions de CO21 de 1,7%, conclut Enerdata ce mardi 28 mai. Dans son nouveau bilan énergétique mondial, le bureau d’étude souligne que la croissance économique reste stable (+3,8%) dans les pays du G20, qui affichent néanmoins un niveau record de consommation énergétique. Dans l’Union européenne, les consommations d’énergie ont un peu diminué, mais cette baisse est compensée par une hausse de celles des Etats-Unis et des pays non membres de l’OCDE. « La consommation énergétique des USA a fortement augmenté, ce qui peut s’expliquer par les conditions climatiques extrêmes auxquelles ils ont été soumis, dont l’hiver très froid qui a demandé beaucoup de chauffage », explique le président d’Enerdata, Pascal Charriau. Par ailleurs, il semblerait que « le développement économique se fasse de façon énergivore : même si on observe un léger gain d’intensité énergétique, l’efficacité énergétique n’est pas améliorée », souligne-t-il.

Patrick Moore auditionné par la Chambre des représentant des Etats Unis à propos du rapport de l’IPBES

by Usbek, 29 mai 2019 in ClimatEnvironnementEnergie


Le  22 mai 2019 la Chambre des représentants des Etats Unis a organisé une audition sur le récent rapport d’évaluationglobale de l’IPBES (Plateforme intergouvernementale scientifique et politique sur la biodiversité et les services éco systémiques ).

Patrick Moore a été invité a donner son témoignage; nous en donnons ci-dessous une traduction (les liens et renvois en bas de page sont du traducteur).


Je vous remercie de m’avoir donné l’occasion de témoigner à l’audience d’aujourd’hui.

En 1971, alors que j’étais doctorant en écologie, je me suis joint à un groupe d’activistes dans un sous-sol d’église à Vancouver, au Canada, et j’ai traversé le Pacifique à bord d’un petit bateau pour protester contre les essais américains de bombes à hydrogène en Alaska. Nous sommes devenus Greenpeace. Après 15 ans au sein du comité directeur, j’ai dû quitter Greenpeace, qui commençait à adopter des politiques que je ne pouvais accepter d’un point de vue scientifique.

Je me suis donné comme mission de toujours appliquer de sains principes scientifiques lors de l’examen des problèmes environnementaux critiques auxquels nous sommes confrontés aujourd’hui.

Ce n’est qu’au début des années 1900, marquées par la disparition définitive de la tourte voyageuse en 1914, que le grand public a commencé à s’intéresser de près à la question de l’extinction des espèces. Cette prise de conscience a été inspirée par l’activisme précoce de Théodore Roosevelt, John Muir et Gifford Pinchot.

Washington Post Gets Excited By Tiny Increase In Green Vote At Euro Elections

by P. Homewood, May 28, 2019 in NotaLotofPeopleKnowThat


You would think the Washington Post should be able to distinguish between a handful of protesting school kids and millions of grown up voters!

In recent months, massive demonstrations over climate change have rocked European capitals, dwarfing the mobilizations of the continent’s far right. Fridays for Future — a movement inspired by Swedish teenage activist Greta Thunberg — has seen countless European teenagers walk out of school to protest climate inaction. It underscores a growing consensus among the next generation of voters that governments must do more to mitigate environmental disaster, and an impatience with political parties that refuse to recognize the urgency of the situation.

Climate change, said an editorial in France’s Liberation newspaper, “has become the principal criteria of judging political action in the European Union.”

Climate science violates the basic precepts of science

by Sanjeev Sabhlok,  May 9, 2019 in TheTimesofIndia


There are two key pillars of science. First, it doesn’t matter how many “scientists” believe something. All of them could be proven wrong by a single new scientific theory or experiment. Science is always tentatively proven, and it is incumbent on everyone who calls himself a scientist to ask questions even about things that are “settled”. The great physicist Richard Feynman rightly said, “Science is the belief in the ignorance of experts”. Scientists must continually question everything and everybody.

Second, science must necessarily make accurate predictions. The global positioning system (GPS) in our mobile phones works only because Einstein’s theories of relativity are accurate to the last possible decimal. Science must not just predict the future: it must predict backwards. Our scientific understanding of cosmic microwave background radiation allows us to literally see the universe as it existed a few thousand years after the Big Bang.

With climate change, things are dramatically unclear and unsettled. Even converting the basic logic of the greenhouse effect into actual estimates for planet Earth is not settled. The IPCC’s Third Assessment Report notes that "If the amount of carbon dioxide were doubled instantaneously … the temperature of the surface-troposphere system would have to increase by 1.2 degrees, in the absence of other changes”. However, some scientists calculate that its impact would be much lower.

UK Government spending foreign aid money to promote fracking in China

by P. Homewood, May 26, 2019 in NotaLotofPeopleKnowThat


Taxpayers’ money earmarked to support overseas development has been spent on supporting China’s fracking industry, The Independent can reveal.

The government is required to spend 0.7 per cent of its national income each year on foreign aid.

But even with climate change threatening the developing world with droughts, flooding and heatwaves, millions have been spent on fossil fuel investment abroad over the past two years.

This includes two schemes aiming to “export the UK’s expertise in shale gas regulation” to China, as controversy about new drilling sites rages back in Britain.

https://www.independent.co.uk/news/uk/politics/fracking-china-foreign-aid-shale-gas-climate-change-environment-dfid-funding-promoting-a8637601.html

 

I won’t bore you with the rest of the story. As you can probably guess, the “Independent” being the “Independent” proceeds to give full coverage to a load of eco cranks, including Christian Aid, who claim that the rapidly changing climate is driving more extreme weather, more acute disasters. (Don’t they know it’s a sin to lie?)

At the end they deign to give a few words to the government spokesperson.

 

Leaving aside the question why China needs our aid at all,  the “Independent” fails to ask the really relevant question of why our government is so keen for us to decarbonise at huge cost, but at the same time thinks it is a good idea to help China develop their natural gas sector?

Sylvie Brunel : un livre qui ne nous gâche pas la vie…

by Prof. A. Préat, 24 mai 2019 in ScienceClimatEnergie


Nous sommes manifestement dans une période médiatico-politique rarement rencontrée dans notre histoire, excepté peut-être aux passages des millénaires et des siècles où les peurs tous azimuts ont engendré chaque fois des comportements irrationnels. Pourtant aujourd’hui nous sommes de plain pied dans un siècle, il n’y a aucune date revêtant une signification particulière et il est presque question de la fin du monde tous les jours puisque le slogan à la mode est ‘la fin du mois ou la fin du monde’. Slogan répété à l’envi par tant de jeunes, de ‘défavorisés’, de retraités et repris en cœur dans les médias et aussi par des scientifiques.

Alors tout ceci est-il fondé ? Faut-il avoir sans cesse peur, peur principalement alimentée par la peur climatique, mais pas uniquement…

German Government Falsified Key IPCC Statement In The Translation Of “IPCC Summary Report To Policy Makers”!

by Prof. dr. H.J. Lüdecke, May 26 2019 in


(German text translated/edited by P Gosselin)
Was it sloppiness or intent? In the IPCC Summary Report for Policymakers published by the Federal Government in German, the most important statement of the original English report was falsified.

IPCC reports are available as comprehensive status reports and get strongly condensed as reports for policymakers. The latter are not to be taken as IPCC-authorized extracts as the governments concerned are allowed contribute in the writing. As a result, information or formulations from the English IPCC original which do not agree with German politics are often omitted in the German IPCC reports for policymakers. This is popularly called censorship. As a result of such falsifications, the status reports and the corresponding reports for policymakers are often contradiction.

Key finding deleted from Summary for Policymakers

One example in the past was the famous Chapter 2.6 of the AR5 Report, in which the IPCC explained in detail that no increase in extreme weather events could be found in climate periods (about 30 years) from 1950 onwards (beginning of more extensive measurements and statistics). EIKE reported on this. But in the accompanying German IPCC report for policymakers, this IPCC finding, which is hardly trivial, was nowhere to be seen.

Scientists discover China has been secretly emitting banned ozone-depleting gas

by Jacob Dubé, May 23, 2019 in National Post


Scientists found that between 40 and 60 per cent of the total global CFC-11 emissions originated from eastern China

A chemical banned around the globe for the last 30 years has made an unfortunate resurgence. And all signs, in a new study, point to China as the culprit.

In the 1980s, countries came together to sign The Montreal Protocol on Substances that Deplete the Ozone Layer, a landmark treaty designed to halt and reduce the production of chlorofluorocarbons (CFC), chemicals used in fridges and foams that had the side effect of tearing through the Earth’s ozone layer.

 
In this graphic, monitoring stations in Japan and Korea designed to track unwanted emissions in the atmosphere attempt to pinpoint the origin of an increase in CFC-11 emissions. Tracking the gas’ presence and weather conditions, scientists concluded it originated from eastern mainland China. A new study published May 22, 2019, found that 40 to 60 per cent of global CFC-11 emissions originated from the region. UNIVERSITY OF BRISTOL

India’s thermal coal output seen growing 4.3% annually till 2028: Report

by Energy World, May 22, 2019


New Delhi: Fitch Solutions Tuesday said India’s thermal coal output is projected to grow at an average annual rate of 4.3 per cent by 2028. “In absolute volume terms, China and India will have the largest impact on the global coal market balance,” Fitch Solutions Macro Research said in a report.

It further said the surge in Chinese imports that occurred over 2015-2017 as a result of dramatic domestic production curbs was a temporary phenomenon.

“We forecast thermal coal production in China to stagnate at 0.5 per cent growth per annum from 2019 onwards, but not decline, as new coal mines in Inner Mongolia, Shaanxi and Shanxi provinces offset mine closures in the rest of the country,” it said.

Aussie Leaders Bow To Change In Political Climate And Back Coal

by Charles the moderator, May 24, 2019 in WUWT


Climate change was supposed to have won the party the Australian election. But yesterday, routed in the polls, panicking Labor Party leaders backed the opening of a coal field bigger than the UK to mining.

Fearing a wipeout in state elections next year amid a rising tide of pro-coal workers and a rebellion against its plans to halve Australia’s carbon emissions, the Labor state government in Queensland accelerated its decision on 105,000 square miles of coal-rich outback land known as the Galilee Basin.

It came days after the party lost what was dubbed as the “climate election” to the incumbent centre-right, pro-coal government of Scott Morrison, suffering the most damage with swings of up to 20 per cent in the coal country of central Queensland and the Hunter Valley of New South Wales.

Queensland’s premier, Annastacia Palaszczuk, announced she was overturning all attempts to block mining and all outstanding approvals would be resolved within three weeks. She said she was “fed up” with her own government’s processes, and that the election had been a “wake-up call” on mining the basin. The move was welcomed by the federal resources minister, Matt Canavan, who told The Times yesterday that the Galilee Basin represented a victory for the “hi-vis workers’ revolution” — a reference to the armies of mine workers, dressed in high-visibility shirts, who make Australia the world’s biggest coal exporter, and seemingly a reference to the “yellow vest” movement in France which battled President Macron on his climate policies.

NOAA predicts near-normal 2019 Atlantic hurricane season

by Anthony Watts, May 23, 2019 in WUWT


El Nino and warmer-than-average Atlantic help shape this season’s intensity

From NOAA press release:

NOAA’s Climate Prediction Center is predicting that a near-normal Atlantic hurricane season is most likely this year. This outlook forecasts a 40% chance of a near-normal season, a 30% chance of an above-normal season and a 30% chance of a below-normal season. The hurricane season officially extends from June 1 to November 30.

For 2019, NOAA predicts a likely range of 9 to 15 named storms (winds of 39 mph or higher), of which 4 to 8 could become hurricanes (winds of 74 mph or higher), including 2 to 4 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). NOAA provides these ranges with a 70% confidence. An average hurricane season produces 12 named storms, of which 6 become hurricanes, including 3 major hurricanes.

New Paper: Arctic Sea Ice Was Far Less Extensive Than Today During The ‘Ice Free’ Early Holocene

by K. Richard, May 23, 2019 in NoTricksZone


Biomarker evidence for Arctic-region sea ice coverage in the northern Barents Sea indicates the most extensive sea ice conditions of the last 9,500 years occurred during the 20th century (0 cal yr BP). In contrast, this region was ice free with open water conditions during the Early Holocene (9,500-5,800 years ago).

Climatologist: Climate Models Are Predicting Too Much Warming

by Dr. Benny Peiser, May 23, 2019 in GWPF


A leading climatologist has said that the computer simulations that are used to predict global warming are failing on a key measure of the climate today and cannot be trusted.

Speaking to a meeting in the Palace of Westminster in London, Professor John Christy of the University of Alabama in Huntsville told MPs and peers that almost all climate models have predicted rapid warming at high altitudes in the tropics:

A paper outlining Dr. Christy’s key findings is published today by the Global Warming Policy Foundation.

Uranium Markets

by World Nuclear Association, updated July 2017


  • Production from world uranium mines now supplies 90% of the requirements of power utilities.

  • Primary production from mines is supplemented by secondary supplies, formerly most from ex-military material but now the products of recycling and stockpiles built up in times of reduced demand.

  • World mine production has expanded significantly since about 2005.

All mineral commodity markets tend to be cyclical, i.e. prices rise and fall substantially over the years, but with these fluctuations superimposed on long-term trend decline in real prices, as technological progress reduces production cost at mines. In the uranium market, however, high prices in the late 1970s gave way to depressed prices in the whole of the period of the 1980s and 1990s, with spot prices below the cost of production for all but the lowest cost mines. Spot prices recovered from 2003 to 2009, but have been weak since then.

The quoted spot prices through to about 2007 applied only to day-to-day marginal trading and represented a small portion of supply, though since 2008 the proportion has approximately doubled, to about one-quarter in the last decade. Most trade is via 3-15 year term contracts with producers selling directly to utilities at a significantly higher price than the spot market, reflecting the security of supply.* The specified price in these contracts is, however, often related to the spot price at the time of delivery. However, as production has risen much faster than demand, fewer long-term contracts are being written.

Hearing on the Biodiversity Report

by Judith Curry, May 22, 2019 in ClimateEtc.


The House Natural Resources Committee Subcommittee on Water, Oceans and Wildlife is holding a Hearing today on Responding to the Global Assessment Report of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services.

The link to the Hearing page is here [link].

Based on my previous experience with this Committee, the written testimonies will not be posted, and the Hearing will live stream on their Facebook page [link]

Here is the list of witnesses:

  • Sir Robert Watson, Immediate Past Chair IPBES
  • Dr. Eduardo S. Brondizio, Co-Chair IPBES Global Assessment 
  • Dr. Yunne Shin, Coordinating Lead Author, IPBES Global Assessment
  • Dr. Patrick Moore, Chairman CO2 Coalition [link to written testimony Moore]
  • Mr. Marc Morano, Founder Climate Depot [link to written testimony Morano]
  • Dr. Jacob Malcolm,  Director Center for Conservation Innovation, Defenders of Wildlife

Quite an interesting list.  Clearly some of the leading honchos for the IPBES Report.  Surprised that the Republicans apparently got to pick several witnesses.

Having Marc Morano on this list is like waving a red cape before a bull.  True to form, Marc has prepared an extremely hard hitting report for his written testimony, which was sent to me (and others) via email.  Excerpts from Morano’s testimony are provided below:

Ship spies largest underwater eruption ever

by Roland Pease, May 21, 2019 in Science


Last week, Marc Chaussidon, director of the Institute of Geophysics in Paris (IPGP), looked at seafloor maps from a recently concluded mission and saw a new mountain. Rising from the Indian Ocean floor between Africa and Madagascar was a giant edifice 800 meters high and 5 kilometers across. In previous maps, there had been nothing. “This thing was built from zero in 6 months!” Chaussidon says.

His team, along with scientists from the French national research agency CNRS and other institutes, had witnessed the birth of a mysterious submarine volcano, the largest such underwater event ever witnessed. “We have never seen anything like this,” says IPGP’s Nathalie Feuillet, leader of an expedition to the site by the research vessel Marion Dufresne, which released its initial results last week.

The quarter-million people living on the French island of Mayotte in the Comoros archipelago knew for months that something was happening. From the middle of last year they felt small earthquakes almost daily, says Laure Fallou, a sociologist with the European-Mediterranean Seismological Centre in Bruyères-le-Châtel, France. People “needed information,” she says. “They were getting very stressed, and were losing sleep.”

Greenland Glaciers Growing Again

by P. Homewood, May 22, 2019 in NotaLotofPeopleKnowThat


European satellites have detailed the abrupt change in behaviour of one of Greenland’s most important glaciers.

In the 2000s, Jakobshavn Isbrae was the fastest flowing ice stream on the island, travelling at 17km a year.

As it sped to the ocean, its front end also retreated and thinned, dropping in height by as much as 20m year.

But now it’s all change. Jakobshavn is travelling much more slowly, and its trunk has even begun to thicken and lengthen.

“It’s a complete reversal in behaviour and it wasn’t predicted,” said Dr Anna Hogg from Leeds University and the UK Centre for Polar Observation and Modelling (CPOM).

“The question now is: what’s next for Jakobshavn? Is this just a pause, or is it a switch-off of the dynamic thinning we’ve seen previously?”

The rapid flow, thinning and retreat of Jakobshavn’s front end in the mid to late 2000s were probably driven by warm ocean water from Disko Bay getting into the fjord and attacking the glacier from below.

The phase change, scientists think, may be related to very cold weather in 2013. This would have resulted in less meltwater coming off the glacier, which in turn might have choked the mechanism that pulls warm ocean water towards Jakobshavn.

Refuting the Smear Machine – Part 1

by Donna Laframboise, Lay 22, 2019 in BigPictureNews


When a journalist thinks for herself about climate change, insults and fabrications follow.

Two days ago I reported that a Washington, DC organization called the Government Accountability Project is smearing me on its website. I explained that PR firms target non-conformist climate reporting in an attempt to police what journalists say.

This story begins with a September 2013 opinion piece written by me and published in the Wall Street Journal. It concerned the Intergovernmental Panel on Climate Change (IPCC), and was headlined:

Warming Up for Another Climate-Change Report
Every six years, a U.N. panel issues its findings, and the media hail them as definitive. Skepticism may be in order.

Within hours, a Rockefeller Foundation funded entity called Climate Nexus released an error-riddled 600-word rebuttal that now resides on the Government Accountability Project’s official-looking website. An organization with ‘accountability’ in its name is smearing me by reprinting material whose actual author remains in the shadows, anonymous to this day.

Line by line, over the course of two blog posts, I will now respond to this collection of factual errors and lazy insults. Let us begin with the first sentence:

Scientists Find No Human Impact On Extreme Rainfall Events In Southeastern Australia…Rather ENSO Related

by P. Gosselin, May 21, 2019 in NoTricksZone


A new study appearing in the Journal of Weather and Climate Extremes titled “Historical extreme rainfall events in southeastern Australia” – led by LindenAshcroft, School of Earth Sciences, University of Melbourne – shows that even more extreme weather in terms of rainfall existed before 1900 in Melbourne, Sydney and Adelaide.

No real trend when examining Sydney, Australia data going back 178 years. Image: Ashcroft et al 2019.

Moreover, the authors found a “moderate and relatively stable relationship between El Niño–Southern Oscillation (ENSO) and annual variations of total rainfall and the number of raindays.”

Interview with Samuele Furfari: European elections

by European Scientist, May 21, 2009


In the context of the European elections, European Scientist is bringing you an series of views from experts from different countries on various topics around science and science policy in Europe, to provide an overview and analysis, which will be useful for the next commission.

 

ES: What is your assessment of energy policy in Europe? What have the major achievements of the outgoing commission been?

The greatest success of the outgoing commission is to have developed a policy to support gas interconnections by financing projects of common interest. The aim is that every single methane molecule that enters the territory of the Union can circulate to any other location. This will help to diversify gas supply sources, particularly from the south of the Union (thanks to more gas arriving as LNG and via the Southern Corridor).

 

ES: There is a wide disparity in energy policy between different countries (e.g. France and Germany). Do you think it is necessary to harmonise policy or on the contrary is it preferable to maintain diversity?

Tertiary hyperthermal events: precursors of the current situation?

by A. Jacobs & A. Préat, May 20, 2019 in SSRN.Elsevier


The focus of this study is based on a detailed analysis of the hyperthermal events of the

Paleocene / Eocene limit of 56 Ma and the lower Eocene (for the 54-52 Ma interval, Figure 1).

This example will show that the Earth has experienced many times much higher temperatures

than today, with warmer, sometimes more acidic oceans and an atmosphere much richer in CO2

(or CH4) than the current one. Are these past events precursors of the current situation?
