Crude weapon; Energy sanctions.

"The largest embargo ever imposed on a petrostate is about to be enforced. Is the global oil market ready for it yet?

EVER SINCE latest sanctions on Russia in February, America's energy policy has pursued two grand, seemingly contradictory aims.

The first is to keep global oil supply high enough that prices remain tolerable and public support for sanctions stays strong. The second is to asphyxiate Vladimir Putin's economy by stemming the flow of dollars Russia earns by flogging oil barrels.

Together they form a circle that is hard to square because, with supply closely tracking demand amid a dearth of new production, taking any oil off the market mechanically triggers higher prices.

The West has nevertheless tried to defy the law of physics by crafting a growing array of measures to meddle in oil markets.

The ones that have been deployed until now have often been piecemeal and involve uncomfortable compromises. Puncturing its own sanctions against Venezuela's thuggish regime, on November 26th America granted permission for Chevron, a big American oil firm, to crank up its production there. America has also released huge volumes from its strategic crude-oil stocks; the reserve is now at its lowest level since 1984. The White House's least productive effort has aimed to cajole Gulf states into pumping more. Within months of President Joe Biden fist-bumping Muhammad Bin Salman, the de facto Saudi ruler, in Riyadh in July, the petrostate and its allies in the Organisation of the Petroleum Exporting Countries (OPEC) declared they would cut output instead. On December 4th the cartel meets again. It looks unlikely to help by increasing output now.

Yet the West's most carefully constructed campaign to outsmart Mr Putin has yet to come into action. In June the EU announced that, come December 5th, it would ban imports of Russian seaborne crude oil, which accounted for 2m barrels per day (b/d), or about 40% of Russia's total crude exports, a year ago. Then it said it would also bar European providers of maritime services, tankers and insurance from helping non- EU buyers get hold of the Russian barrels it shuns--a powerful tool, given those firms dominate the global shipping market. It soon dawned on America that, together, those two measures had the potential to squeeze global oil supply. And so it insisted on introducing a weakening clause: provided they agree to pay a maximum price, set by the G7, for Russia's oil, non-Western buyers could continue to buy European insurance.

As we went to press the level of this "price cap" was still being debated among Europeans. Some, led by Poland and the Baltic states, want the cap to be low so as to hurt Russia's finances. Others, worried about their shipping industries or retaliation from Russia, want to keep it close to market levels. Rumours filtering out from the talks suggest it may end up near $60 a barrel--a discount of nearly 30% to the current price of Brent, the global benchmark, of $85 a barrel--which is about what Russia sells its oil for these days anyway. Whatever the outcome one thing is certain. Never before has such a fiddly set of measures hit the global oil market at once. Many of these have been signalled for so long that they may cause few problems. But there are reasons to think the boat could be rocked, at least for a while.

In an optimistic scenario the package of sanctions could manage to reconcile the West's two contradictory aims. The embargo would ensure Europe no longer fuels Mr Putin's economy: last month the bloc still bought 2.4m b/d of crude and refined oil from Russia. Meanwhile the price cap, says an American Treasury official, would act as a "release valve", keeping the global market in balance by letting developing countries buy Russian oil at a discount. Russia would receive less money whether or not those countries sign up to the plan, because the mere existence of a cap, or so America reckons, would boost their bargaining power.

In the absence of a low enough price cap, as is likely to be the case, the cost to Russia would be real but modest. It would add yet more inconvenience to that created by the West's broader arsenal of sanctions, which may impair Russia's economy in the long run but have hardly proved terminal so far. The discounts borne by Russian grades over regional benchmarks have widened in recent weeks but remain well below those seen in the aftermath of the sanctions. At least the embargo would not roil crude markets--or so commodities markets suggest. Brent futures, which in June indicated a year-ahead oil price approaching $100 a barrel, now place it closer to $85 (see chart panel).

Most traders expect an acceleration of the shift in fuel flows seen so far this year, with India and China taking over from Europe as Russia's biggest customers.

This happy story assumes no logistical hiccups will prevent decades-old trading patterns from undergoing a smooth but rapid transition. A less rosy scenario, however, could see sanctions throw spanners in the spigots by introducing unwanted friction. Three bottlenecks stand out: a crunch in tankers, an insurance gap and a global shortage in risk appetite.

Start with the tankers. Cyprus, Greece and Malta loom so large in shipping that Europe's ban on the provision of maritime services to countries that do not sign up to the cap--and many of them, loth to endorse American interference in commodity markets, have signalled they won't--could create a big shortage of ships capable of carrying Russian crude. Claudio Galimberti of Rystad Energy, a data firm, anticipates a shortfall of some 70 vessels, with an aggregate carrying capacity of 750,000 b/d, lasting two to three months.

Eventually this problem should work itself out. Industry insiders point to an ever growing "dark fleet" that is absorbing vessels from established sanction-busters in Iran and Venezuela. Russian firms are bringing mothballed vessels back into service; EU shipowners are also transferring assets to operators outside the G7. A top energy trader reckons that, by February, there will be enough ships to transport Russian crude, though vessels to redirect refined products such as diesel from short-haul routes in Europe to distant new customers may stay scarce for some time.

The crunch in insurance coverage is a bigger potential snag. It is not that Middle-Eastern or Asian countries keen on Russian barrels do not have local firms with the financial muscle to insure tankers and cargo. What they may soon lack is cover for much bigger risks like oil spills, liabilities for which can easily reach half a billion dollars. Few insurers new to the market will look forward to becoming liable for an ageing Venezuelan vessel going through Danish straits a mere 15m deep, says a veteran oil trader, without a big backstop.

The problem is that this sort of backstop--reinsurance--demands deep pools of private capital hard to find outside the West. Perhaps the Chinese and Indian governments could be persuaded to offer sovereign reinsurance, though market insiders doubt they have the stomach. In fact some traders reckon Asian buyers could buy less Russian oil rather than more as the insurance ban comes into force.

The third bottleneck could be a lack of appetite outside the G7 for the perceived risks of circumventing a scheme designed by the West. Many do not believe American promises to remain hands-off if countries choose to go around the cap. It does not help that, in its most recent sanction campaigns, such as those targeted at Iran, America has studiously kept the perimeter and degree of enforcement of penalties vague so as to deter anyone from dealing with its foes. The practice, known in sanctions parlance as "constructive ambiguity", is hard to roll back.

All this could cause a chunk of Russian oil exports to fall off the map, prompting prices to jump.

But a much worse scenario, where Russia voluntarily slashes its oil exports and prices get out of control, is also possible. It may happen if China, having to forsake its purchases from other countries to buy yet more Russian oil, tries to drive too hard a bargain. More likely it would be a unilateral decision by Mr Putin. It could incur huge costs: Russia derives 40% of its export revenues from oil sales. But that might be worth bearing temporarily if it drives global prices up, hurting the West and giving Russia more leverage in negotiations with buyers, without inflicting intolerable damage to wells. The country's decision to shut temporarily nearly 2m b/d of crude production during the pandemic resulted in only a 300,000 b/d loss in long-term capacity, according to Energy Intelligence, an industry publisher.

Up to now the G7's energy policy has been hashed out in painstaking detail in Washington, DC, and Brussels. But, to paraphrase Mike Tyson, everyone has a great plan until they get punched in the face—and Mr Putin is pulling no punches right now. The price-cap's first contact with reality could be rough.” [1]

Užterštas oras gali priversti žmones nusižudyti

"UŽTERŠTAS ORAS kenkia jūsų sveikatai. Didina insulto, širdies ligų ir kvėpavimo takų ligų riziką. Tai taip pat susiję su žemu produktyvumu darbe ir prastais akademinių testų rezultatais. O tarša dar gali turėti - labiau grėsmingą poveikį, taip pat gali paskatinti savižudybę.

 

Claudia Persico ir Davidas Marcotte'as iš Amerikos universiteto Vašingtone tyrė savižudybes visoje Amerikoje 2003–2010 m. Jie ieškojo ryšio tarp savižudybių ir smulkių kietųjų dalelių, žinomų, kaip PM2,5, lygių, nes tos dalelės yra mažesnės, nei 2,5 mikronų skersai. Jos gali patekti į kraują per plaučius. Jie iškėlė hipotezę, kad prasta oro kokybė pablogina žmonių nuotaiką, o tai savo ruožtu padidina tikimybę, kad kam nors kils minčių apie savižudybę.

 

Savižudybių rodikliai skiriasi dėl daugelio priežasčių, todėl du mokslininkai sutelkė dėmesį į kasdienius savižudybių skaičiaus pokyčius tam tikrose vietose su svyruojančiu oro taršos lygiu, kurį sukelia vėjo krypties pokyčiai. Pavyzdžiui, Bostone šiaurės rytai, pučiantys į miestą iš pramoninių rajonų, atneša orą, pernešantį maždaug penkiais mikrogramais viename kubiniame metre daugiau PM2,5 nei vakarų vėjas iš Masačusetso valstijos aukštutinės valstijos. Tyrėjai ištyrė šiuos su vėju susijusius taršos modelius kiekvienoje Amerikos apskrityje ir suderino juos su kasdiene savižudybių statistika.

 

Jų analizę kaip darbo dokumentą, paskelbė Nacionalinis ekonominių tyrimų biuras Kembridže, Masačusetso valstijoje.

 

Nustatyta, kad PM2,5 padidėjimas vienu mikrogramu kubiniame metre tam tikroje vietoje buvo susijęs su vidutiniu dienos savižudybių skaičiaus padidėjimu šiek tiek mažiau, nei 0,5 proc. bandymų nusižudyti, o jei toks vėjas pūtė mėnesį, tai bandančių nusižudyti  padaugėjo 50 proc.

 

Uždeganti išvada

 

Šie rezultatai išliko net tada, kai buvo kontroliuojama temperatūra ir debesuotumas, o tai gali turėti įtakos nuotaikai ir būti susiję su vėjo kryptimi. Tačiau buvo geografinių skirtumų. Dr. Persico ir dr. Marcotte nustatė, kad taršos poveikis savižudybių skaičiui buvo didžiausias skurdesnėse apskrityse, tose, kuriose yra daugiau nedarbo, ir tose, kuriose galioja liberalūs ginklų nuosavybės įstatymai, nes šaunamojo ginklo turėjimas, ko gero, palengvina potencialiam savižudžiui nusižudyti.

 

Norėdami tiesiogiai patikrinti idėją, kad prasta oro kokybė blogina nuotaiką, jie paėmė apklausų duomenis apie nuotaiką ir psichinę būseną ir patikrino, ar atsakymai buvo susiję su užterštumo lygiu respondentų gimtajame mieste mėnesį iki apklausos.

 

Jie nustatė, kad net viena papildoma diena per įprastą mėnesį, per kurią PM2,5 lygis viršijo 35 mikrogramus kubiniame metre, buvo susijus su nuolatiniu žmonių pranešimu, kad jie jaučiasi prislėgti, jiems mažai malonu veikti ir kad buvo pavargęs ir stokojantis energijos. Jie taip pat nustatė, kad maždaug 1 % padaugėjo pacientų, kuriems gydytojas pasakė, kad jie serga depresija.

 

Ankstesni tyrimai parodė, kad PM2.5 tarša gali sukelti uždegiminį atsaką organuose, įskaitant smegenis. Daugelis mokslininkų mano, kad uždegimas sutrikdo normalią smegenų atlygio takų, padedančių reguliuoti nuotaiką, veiklą. Atsižvelgiant į tai, kai kurie tyrimai parodė, kad priešuždegiminiai vaistai pagerina depresija sergančių žmonių nuotaiką. Tuo tarpu kiti darbai rodo, kad tokių žmonių kraujyje nuolat yra didesnė baltymų, vadinamų citokinais, išsiskiriančių uždegimo metu, koncentracija, o savižudžių aukų, ištirtų po mirties, smegenyse yra daug uždegiminių citokinų.

 

Amerikoje vidutinis PM2,5 lygis apgyvendintose vietovėse yra maždaug du kartus didesnis už Pasaulio sveikatos organizacijos (PSO) rekomenduojamą didžiausią penkių mikrogramų kubiniame metre lygį.

 

2021 m. paskelbtas tyrimas rodo, kad laikantis šio PSO skaičiaus galima išgelbėti 100 000 gyvybių per metus.

 

Šiame kontekste 770 savižudybių, kurių, jei dr. Persico ir dr. Marcotte teisūs, būtų išvengta sumažinus šį skaičių, yra  papildomas sutaupymas. Tačiau savižudybė yra tokia tragiška gyvenimo pabaiga, kad jis būtų ypač sveikintinas. [1]

 

Štai kodėl pastaruoju metu savižudybių rodikliai Lietuvoje tokie dideli. Visi šie senoviniai dyzeliniai automobiliai, kuriuos atsivežame iš Vokietijos, gamina tonas dalelių ir tiesiogine prasme mus žudo.

Contaminated air can drive people to kill themselves


"POLLUTED AIR is bad for your health. It increases the risk of strokes, heart disease and a list of respiratory illnesses. It is linked, as well, to low productivity at work and poor scores on academic tests. And pollution may have a yet-more-sinister effect. It may also promote suicide.

Claudia Persico and David Marcotte of the American University, in Washington, DC, examined suicides throughout America between 2003 and 2010. They looked for a link between these and aerial levels of fine particulate matter known as PM2.5 because its particles are less than 2.5 microns across. These can enter the bloodstream via the lungs. They hypothesised that poor air quality worsens people's moods, which in turn increases the likelihood of someone experiencing suicidal thoughts.

Suicide rates vary for many reasons, so the two researchers concentrated on correlating day-to-day changes in the number of suicides in particular places with fluctuating air-pollution levels caused by alterations in wind direction. In Boston, for example, north-easterlies blowing into the city from industrial areas bring air carrying around five micrograms per cubic metre more PM2.5 than westerlies from upstate Massachusetts. The researchers worked out these wind-related pollution patterns for every county in America, and matched them with daily suicide statistics.

Their analysis was published as a working paper by the National Bureau of Economic Research, in Cambridge, Massachusetts. 

It found that an increase of one microgram per cubic metre in PM2.5 in a given place was linked to an average rise in daily suicide rates of just under 0.5%, and if that increased level was sustained for a month, hospital admissions connected with attempted suicides rose by 50%.

An inflammatory conclusion

These results stood up even when controlled for temperature and cloud cover, which might feasibly affect mood and be related to wind direction. There was, however, geographical variation. Dr Persico and Dr Marcotte found that the impact of pollution on suicide rates was greatest in poorer counties, in those with more unemployment, and in those with liberal gun-ownership laws, since access to a firearm presumably makes it easier for a potential suicide to turn thought into deed.

To test directly the idea that poor air quality worsens mood they took data from surveys about mood and mental state and checked whether the answers were related to pollution levels in respondents' home towns in the month leading up to the survey. 

They found that even a single additional day in a typical month during which PM2.5 levels were above 35 micrograms per cubic metre was associated with a small but consistent increase in how often people reported they felt depressed, had little pleasure in doing things or were tired and lacked energy. They also found an increase of around 1% in the number who had been told by a doctor that they had depression.

Previous research has shown that PM2.5 pollution can cause an inflammatory response in organs, including the brain. Many researchers think inflammation disrupts normal operation of the brain's reward pathways, which help regulate mood. Consistent with this, some trials have found that anti-inflammatory drugs improve mood in those with depression. Other work, meanwhile, shows that such people have consistently higher concentrations than others of proteins called cytokines, released during inflammation, in their blood, and that suicide victims, examined after death, have high levels of inflammatory cytokines in their brains.

In America, average PM2.5 levels in populated areas are around twice the World Health Organisation recommended maximum of five micrograms per cubic metre. 

A study published in 2021 suggests meeting that figure might save 100,000 lives a year. 

In this context the 770 suicides which would, if Dr Persico and Dr Marcotte are correct, be avoided by this reduction are only a small extra saving. But suicide is such a tragic end to life that it would be a particularly welcome one.” [1]

This why suicide rates in Lithuania are so big recently. All these ancient diesel cars that we bring from Germany are producing tons of particles and killing us literally.
