Open thread: steel without coal

The most pressing challenge for bringing climate change under control is replacing the world’s energy sources for electricity production, building heating and cooling, and transport. At the same time, humanity needs to learn how to do everything necessary to maintain a technological civilization without fossil fuels. That includes agriculture, as well as the production of crucial raw materials including steel.

This may be one area where hydrogen is a real solution:

[O]ne of the biggest industrial sources of carbon dioxide is not directly energy-related at all.

This is the reduction of iron ore (usually an oxide of iron) to the metal itself by reacting the ore with carbon monoxide made from coke. That produces iron and carbon dioxide. React the ore with hydrogen instead, and the waste product is water. Several firms—including ArcelorMittal, a multinational steelmaker, and a conglomerate of SSAB, a Finnish-Swedish steelmaker, LKAB, a Swedish iron-ore producer, and Vattenfall, an energy company, also Swedish—are examining this possibility.

Climate-safe sources of raw materials are necessary both practically and politically, since people point to the use of fossil fuels in their production as reasons why they cannot be abandoned.

Cyber defences create their own risks

In addition to aforementioned rules about internet and computer security (1, 2, 3, 4) it’s worth mentioning that security measures can create their own vulnerabilities.

That’s true in terms of human systems. For instance, granting high-level powers to system administrators creates risks that they will exploit them deliberately or have their credentials stolen, or simply used after being left unguarded.

It’s can also be true for technical means. For instance, people often misunderstand TOR and believe that it makes everything about their web browsing anonymous. Really, it just routes the traffic several times within an encrypted network to disguise the origin before using an exit node to communicate with the target server, potentially with no encryption. Since people may be more likely to use TOR for sensitive or illicit purposes, those exit nodes are likely a target for both freelancers and governments.

Some recent stories have alleged that the virtual private networks (VPNs) which people use to protect themselves from an untrusted local network can create risks as well:

Earlier, people alleged that Facebook was using its Onavo VPN to snoop on users.

The draw of martyrdom

Describing the period in the 1980s when Osama bin Laden was emerging as a major private fundraiser for the mujahideen resisting the Soviet invasion of Afghanistan:

The lure of an illustrious and meaningful death was especially powerful in cases where the pleasures and rewards of life were crushed by government oppression and economic deprivation. From Iraq to Morocco, Arab governments had stifled freedom and signally failed to create wealth at the very time when democracy and personal income were sharply climbing in virtually all other parts of the globe. Saudi Arabia, the richest of the lot, was such a notoriously unproductive country that the extraordinary abundance of petroleum has failed to generate any other significant source of income; indeed, if one subtracted the oil revenue of the Gulf countries, 260 million Arabs exported less than the 5 million Finns. Radicalism usually prospers in the gap between rising expectations and declining opportunities. This is especially true when the population is young, idle, and bored; where the art is impoverished; where entertainment—movies, theater, music—is policed or absent altogether; and where young men are set apart from the consoling and socializing presence of women. Adult illiteracy remained the norm in many Arab countries. Unemployment was among the highest in the developing world. Anger, resentment, and humiliation spurred young Arabs to search for dramatic remedies.

Martyrdom promised such young men an ideal alternative to a life that was so sparing in its rewards. A glorious death beckoned to the sinner, who would be forgiven, it is said, with the first spurt of blood, and he would behold his place in Paradise even before his death. Seventy members of his household might be spared the fires of hell because of his sacrifice. The martyr who is poor will be crowned in heaven with a jewel more valuable than the earth itself. And for those young men who came from cultures where women are shuttered away and rendered unattainable for someone without prospects, martyrdom offered the conjugal pleasures of seventy-two virgins—”the dark-eyed houris,” as the Quran describes them, “chaste as hidden pearls.” They awaited the martyr with feasts of meat and cups of the purest wine.

The pageant of martyrdom that [Abdullah] Azzam limned before his worldwide audience created the death cult that would one day form the core of al-Qaeda. For the journalists covering the war, the Arab Afghans were a curious sideshow to the real fighting, set apart by their obsession with dying. When a fighter fell, his comrades would congratulate him and weep because they were not also slain in battle. These scenes struck other Muslims as bizarre. The Afghans were fighting for their country, not Paradise or an idealized Islamic community. For them, martyrdom was not such a high priority.

Rahimullah Yusufzai, the Peshawar bureau chief for the News, a Pakistani daily, observed a camp of Arab Afghans that was under attack in Jalalabad. The Arabs had pitched white tents on the front lines, where they were easy marks for Soviet bombers. “Why?” the reporter asked incredulously. “We want them to bomb us!” the men told him. “We want to die!” They believed that they were answering God’s call. If they were truly blessed, God would reward them with a martyr’s death. “I wish I could raid and be slain, and then raid and be slain, and then raid and be slain,” bin Laden later declared, quoting the Prophet.

Jason Kenney and the end of oil

Don Braid is reporting on recent comments from Alberta premier Jason Kenney, presumably uttered in the hope of bolstering the chances the Trudeau cabinet will approve the Teck Frontier mine:

“Over the next decades as we go through the energy transition, we all know that there will be a continued demand for crude,” he told a panel at Washington’s Wilson Center last Friday.

Kenney added: “It is preferable that the last barrel in that transition period comes from a stable, reliable liberal democracy with among the highest environmental, human-rights and labour standards on earth.”

Energy transition. Last barrel. Transition period. Six not-so-little words we’ve never heard clearly from Kenney before.

“I have a firm grasp of the obvious,” Kenney said in a later interview. “There is no reasonable person that can deny that in the decades to come we will see a gradual shift from hydrocarbon-based energy to other forms of energy.”

There is still a lot to criticize, of course, and Canadian oil is far less positive from an environmental and human rights stance than industry boosters admit.

Still, there is cause to see these comments as significant. Even for a politician that defines their political programme in terms of support to the oil and gas industry it has become necessary to acknowledge that there is a limit to total permissible global production because of climate change, even if Kenney talks about it here in the impersonal and indirect language of a ‘change in demand’.

Kenney is setting out the logic of the bitumen industry’s downfall here, even though he is trying to do the opposite. Once you accept that oil production can’t continue forever or until all reserves are exhausted, and then you start deciding which oil to produce or not produce on economic and environmental grounds, unless you have motivated reasoning and a set conclusion all along, few people are going to conclude that it makes sense for that oil to come from the bitumen sands.
