It's been a year or more but Russia was budgeting using $40 oil.
That plus a bumper wheat crop (no GMO), a surging demand for their military equipment, low debt, and a rapidly growing stash of gold will keep them in the game for the foreseeable future.

Terry

An interesting article from:-

http://vestnikkavkaza.net/news/Russia-reduces-budget-s-dependence-on-oil.html

"Our non-oil and gas budget deficit will reduce to less than 6% in 2018-2020, and in 2019 we stop spending our reserves, which we continue to use this year and in next year," TASS cited Siluanov as saying.

Note that they have been using up their cash reserves and expect to do so for up to 2 more years.
Note also your comment that surging sales of military equipment are helping. Who to and what for? Good news for Russia, maybe not if this reflects growing tensions elsewhere.

A less sanguine view comes from the Gaidar Institute for Economic Policy, the Russian Presidential Academy of National Economy and Public Administration (RANEPA)  :-

Venezuela, for example,  has a breakeven price of about $28/barrel.  They could either sell a small number of barrels at $100 or a lot of oil at $40 and gain the capital they need to cover debts.  The problem is that there appears to be enough oil that can be sold for less.
At $50 a barrel, Venezuela cannot cover the cost of basic healthcare, education, roads etc and debt repayments. It cannot afford basic imports. The break even price to keep Venezuela afloat is more than $100.
You can't avoid arithmetic. For Venezuela extreme weather events from AGW just make it worse.

This is an extract from a post on The Trump Presidency by Sigmetnow who found it on facebook
I reproduce it in full as I think it is necessary to give it as wide a circulation as possible.

"We are safe in a hotel for another night. Well, those who know me knew my silence on the politics involved here would not last long. If it bothers you, I understand but it's time to say this. I just watched a man on television describe how his wife died in his arms in Santa Rosa and a mother in tears recounting her son succumbing to the flames in their driveway while trying to escape. People have been burned alive. A women who barely survived the carnage in Las Vegas lost her house. A woman in a wheelchair was waiting to die until a brave sheriff's officer risked his life to save her. Rescuers are finding bodies burnt beyond recognition; other reduced to bones and ash. So far, 36 people have lost their lives, 100,000 people have been evacuated trying their best to find shelter and almost 6,000 structures have been totally destroyed. People are enduring unimaginable circumstances. Also, there is no telling how many pets and wildlife didn't make it. No one can really imagine what this hell is like.

Not that I really care what he says or does, but Trump has not tweeted one word, made a speech, or shown any compassion at all for the victims of the California wildfires. Nothing. Zero. Worthless liberal heathens that we are and not as deserving as the dead red states of Texas and Florida. Are the dead in California less dead? Are their destroyed homes homes not a big deal? Are 100,000 refugees just a statistic? Others do care what the president says and his silence is deafening. If nothing else, the incredibly courageous and selfless firefighters, police, pilots, doctors, nurses and other civil servants deserve thanks and acknowledgment.

Finally, anyone who respects the educated professionals whose lives have been devoted to studying the earth and it's climate, understands that the warming earth and oceans increases the severity of nature's worst tragedies. Like fires, hurricanes and tornadoes as any American could see with their own eyes this year. Warm waters, torrential rains, overgrown brush, excessive heat, severe droughts and hurricane force winds are all a result. This is going to happen again and again as the Trump administration and their GOP and corporate enablers continue to dismantle all efforts aimed at slowing or reversing climate change. This is the new reality."

The NHC is its discussion on Ophelia, noted that SSTs were 1 to 2 degrees celsius above "normal" allowing it to maintain hurricane status and increase in intensity even at a relatively high latitude.

One wonders what with this AGW everyone is going on about, and 93% of it going into the oceans, whether the magic 26 celsius SST required for hurricane formation and maintenance is moving into higher latitudes. If so, Ophelia events might become more frequent.

The melt season is over. But where else to put the data on what is happening in general to the ice sheet.

Data from http://www.dmi.dk/en/groenland/maalinger/greenland-ice-sheet-surface-mass-budget/ shows that after an active September (much greater than in 2016) precipitation in October so far has been average (much less than 2016). Over the next few days no major precipitation seems likely. (The NHC reckon the remains of Ophelia will dissipate over Scandinavia.)

The absence of above average mass gain is of equal significance as its presence.

JAXA DATA
Although JAXA is having a Sunday off, herewith a table and graph up to 13th October. The table shows the large variation in remaining extent gain that happened in recent years.

The graph does show that on average daily extent gain is at maximum at this time, and later settles back a bit. Methinks this is simply a matter of geography, not climate variation. As ice extent reaches more of the Russian shore further extent gain there is impossible.

The graph also shows that for an individual year (e.g. 2016) the average is irrelevant not just for the season but also any day, week or month. Oneself can but watch record and wonder and hope A-Team and his ilk come up with the goods.

Bob Wallace has shown one part of the oil equation, i.e. oil production costs.
Another part is break-even price by country, which reflects the extent of a country's dependence on oil revenues.
Comparing that with current and future oil price tells one how much of a structural problem a country has.

Libya, Nigeria, Venezuela, Iran, Iraq Russia and Saudi Arabia have production costs well below current sale price. But their Governments need a sale price of $100 + to balance the books, i.e. they are going bust, either borrowing, or if they have any, running down their cash reserves.

The same basic components apply to Natural Gas

Everyone with an ounce of rational thought in their brain knows that any sustained increase in crude and natural gas prices results in a boost to US shale production and a boost to renewable energy investment. Many oil producing countries will fail to create an economy independent of oil within the next few years. They will go bust. So will over-exposed investors and lenders. People will starve. It will be messy and violent.

Someone please prove I am wrong.

Bloomberg says Saudi going to cut production again and hoping others will join in. Obvious result will be US production spike.

I honestly believe that speculating on short to medium term movements in oil prices is a mug's game. In the long term (perhaps even  by 2022?) renewables and EVs will start to really impact demand. Saudi Arabia and many others will be in real trouble. The USA may well ban imports and exports to keep the shale oil and gas industry going for some years longer.

The geopolitics of it  all will be fascinating - shifting of political tectonic plates or what.

From previous post by shared humanity the USGS study refers to seepage (slow release?) at 80-90 meters depth near Svalbard. The Russian study talks about rapid release at  max of 50 m depth in the ESAS.

Hullo Oren.
Idiot qu.1. Not the faintest idea. Vague memory of a study on seas near Svalbard ?
Idiot qu. 2. Found a paper - them Russkies again. Suggests cause of quick increase in co2 from 190  to 270 ppm that happened soon after last inter glacial may have been triggered by permafrost exposed as ice sheet retreated. Hence lots of interest from scientists looking at NOW?

Found a paper that said most ch4 in the ESAS is Pleistocene. Also in other papers talk about greatly increased flow in Siberian rivers dumping big amounts from peatlands in the ESAS during the Holocene and accelerating now.
Northern sea route opens. Insolation. Shallow sea warms. Permafrost on sea floor melts. Many many gt of ch4 escapes. Climate stuffed.

Ps . Doing this on mobile so can't give you links. Your turn to get a headache first finding and then wading thru very very scientific abstracts.

Permafrost / Re: Arctic Methane Release
« on: October 09, 2017, 10:13:42 PM »
From what I read it would seem that when local conditions favour slow release of ch4 this allows the ch4 bubbles to completely dissolve in the ocean thus encouraging algal blooms.

The studies by Semiltov and Shakhova seem to me to point to the possibility of rapid release of ch4 in the less than 50 m depth of large parts of the ESS as the permafrost cap over the hydrates weakens,  thus allowing much of the ch4 to be released as gas into the atmosphere. Shallow seas warm up quickly to sufficient depth to attack the permafrost.

Not only hydrates but there are also perhaps large amounts of free ch4 gas at greater depth formed from the decay over many thousands of years of carbon rich soil confined under pressure would be released as the hydrate layer thinned and broke. Rather like the classic geology of oil and gas under pressure trapped under a salt dome. Puncture the cap and whoosh! a gusher.

Different geomorphology and ocean depth and temperatures produce different results. The logic is too persuasive for comfort, especially if the Arctic ocean in the ESAS continues to warm.

First we must finally accept how dire our situation is and the need for coordinated and radical change.

Second, we must embrace a sense of efficacy or the first will, in fact, drive us insane.

“If there is one thing we cannot allow to become extinct, it is the species that provide the food that sustains each and every one of the seven billion people on our planet,”

Who needs Climate Change to implement the 6th Mass Extinction ?

Robertscribbler.com has just put this up:-
Half-way to Catastrophe — Global Hothouse Extinction to be Triggered by or Before 2100 Without Rapid Emissions Cuts
Fossil Fuel Burning = Race Toward a 6th Mass Extinction

Trouble is, the 6th Mass Extinction is well underway without much help from climate change. The following links give a clue:-

http://www.pnas.org/content/114/30/E6089.full  -
"Biological annihilation via the ongoing sixth mass extinction signaled by vertebrate population losses and declines"

https://www.scientificamerican.com/article/vertebrate-populations-plummet-in-4-decades/
Vertebrate Populations Plummet in 4 Decades

"Deforestation and other human actions have cut the populations of mammals, birds, amphibians and fish by 58 percent since 1970"

https://www.theguardian.com/environment/2016/oct/27/world-on-track-to-lose-two-thirds-of-wild-animals-by-2020-major-report-warns
"World on track to lose two-thirds of wild animals by 2020, major report warns
Living Planet Index shows vertebrate populations are set to decline by 67% on 1970 levels unless urgent action is taken to reduce humanity’s impact"

http://www.pnas.org/content/113/49/14079.full
Large numbers of vertebrates began rapid population decline in the late 19th century

"Significance
The current rate of species extinction is ∼1,000 times the background rate of extinction and is attributable to human impact, ecological and demographic fluctuations, and inbreeding due to small population sizes. The rate and the initiation date of rapid population decline (RPD) can provide important clues about the driving forces of population decline in threatened species, but they are generally unknown. We analyzed the genetic diversity data in 2,764 vertebrate species. Our population genetics modeling suggests that in many threatened vertebrate species the RPD on average began in the late 19th century, and the mean current size of threatened vertebrates is only 5% of their ancestral size. We estimated a ∼25% population decline every 10 y in threatened vertebrate species."

Yes, climate change is now an increasingly major contribution to this process but mankind was doing a pretty good job anyway. 

PS: I did a quick and dirty projection, based on the assumption that population depreciation tends to be on a reducing balance basis, i.e. x percent loss each year of the remaining population. The studies quoted above suggest x is about 2.5%.

That suggests a remaining vertebrate total population of between 10 and 20 % by 2050 compared with 1970.

Real mathematicians are needed to estimate how many individual species extinctions that implies, and also assumes pressures on vertebrate populations remain the same in the future.

So maybe total extermination of vertebrates by 2050 is an exaggeration. Or maybe not.

The melting season is underway (although this year the sea ice extent has increased a bit in the last few days despite that polynya in the Weddell Sea that apparently indicates up-welling of major ocean heat from the depths ).

So I've been having a look at extent loss from max to min over the satellite record.

The main result is how small the variation from the average melt has been over the years. A maximum of +5% in 2005-06 and a minimum of -3% in 2007-08.

Whoops - error in table corrected

The second result is that the average melt in the last 10 years would result in a new record minimum extent in Feb/Mar 2018.

"Unpredictable nature of Antarctic sea ice levels the focus at conference of meteorology experts in Australia this week.

Better mapping and predicting these changes to aid polar shipping is the goal of the International Ice Charting Working Group Tasmanian meeting.

Unpredictable sea ice levels are creating headaches for an increasing number of tourist and research boats visiting the Antarctic.

The working group estimates about 50 cruise vessels took almost 35,000 tourists to the Antarctic last year."

The Aussie Government is following the Trump Presidency game plan.

$2.5bn on a coal-fired power station? That's good old pork barrelling

"The Queensland Liberal-National party (LNP) are promising that if they are elected to government they’ll build a new coal power station in northern Queensland. And just this week the prime minister, Malcolm Turnbull, announced that if Queenslanders elected the LNP at the next state election, all Australian taxpayers would help fund it.

It’s important to note that this would involve a serious amount of taxpayers’ money, because banks and power companies have made it clear they aren’t remotely interested in funding such a plant."

Seems the passage is closed again by new ice
The NE passage will be open for some time. The Russkies will be glad.

This thread is called IJIS 'cos it is for Jaxa data - though I usually stick that at the top of all my postings. There is always a difference with NSIDC but of little moment.

Melting may have stopped - though a last spike just might be on the way - but a second spike in precipitation started two days ago and looks like continuing for a day or three. This makes September not a quiet month compared with last year and average years.

It is just possible that sometime next week the remnants of Lee and Maria will arrive. If Greenland doesn't get it, then the UK is the most likely destination.

JAXA DATA (Usually follows NSIDC very closely)
The continued decline in extent, despite -ve or neutral temp and SST anomalies, would make one think the 12 September extent of 18.062 million km2 was definitely the maximum, given that the date of maximum has passed for all years but one - 2015. Extent shot up from now to 2nd October. (see table). 2017 could do the same.

One might also think that 2017-2018 would continue to be a record or near record-low in daily extent. However, the previous record low maximum years of 1986 and 2002 flattered to deceive, extent gently moving into the pack as the melt season progressed. In contrast, the graph below shows how in early November 2016, extent dropped like a stone to the lowest in the satellie record and stayed there until April 2017.

The Antarctic is unpredictable.
