Delaying climate action is the most expensive thing we will ever do

Figure from my 2009 blog post, showing why delaying the global peak year for greenhouse gas pollution emissions means having to cut emissions much faster in the 2020s and 2030s to achieve the same temperature target:

Emissions pathways to give 75% chance of limiting global warming to 2ºC

Tweeted by Greta Thunberg today:

All this delay mutually reinforces the risks of catastrophes. People keep investing in fossil fuels, so they have more to lose from decarbonization. We keep putting off emission cuts, meaning that their eventual rate will need to be much more draconian than if we had started promptly when the risk of catastrophic climate change became well-recognized in the 1990s. We’re committing ourselves to more severe climate change effects, meaning more forced relocation, severe droughts, extreme weather events, and adaptation costs in general measured in both wealth and lives. We’re missing the chance to build global cooperation and overcome the parochial one-country-mindset mentality that makes global environmental problems into collective action problems.

twitter’s an addictive land of trolls

I have written before about the cognitive and emotional (and insomniac) downsides of checking the news too often. It seems worth re-emphasizing how twitter is a worst-case scenario in this regard, at least for people more interested in developments in matters of public interest than developments in the lives of friends and acquaintances, where facebook is untouchable.

With twitter it’s possible to use any internet-connected device to get an endless stream of updates and — crucially — little decisions for as long as you want at any time of day. It’s an exercise perfectly crafted to short-circuit longer term planning, even at the scale of turning off your phone to get a night’s rest before a busy day tomorrow. Every tweet presents the cognitive task of interpreting the content; determining whether it contains any factual, ethical, or political claims; and then evaluating that content in light of what the user believes and what, if anything, they are trying to accomplish through engagement online. Even for fairly passive users, every tweet involves the decision of whether to publicly ‘like’ or ‘retweet’ it, forcing your brain to engage decision-making circuitry more often and immediately than when reading a news article or book. Of course the real addictive prompts come from the social features: the notifications that someone has ‘liked’ or responded to your tweet. That engages all the emotional machinery which we use to socialize with others, maintain or alter our beliefs about the world, and protect out own self-esteem. It also embodies the slot machine logic of unpredictable and variable responses to the same action, ranging from someone amazing expressing agreement or saying something clever in response to your message to the depredations of the most hateful trolls.

Twitter often exposes me to content which I subsequently wish I could unsee, including particularly blockheaded claims and arguments which tend to re-emerge with a sense of frustration and anger in the shower the next day. The platform isn’t entirely without virtues — it can provide useful or at least engaging up-to-the-minute information and analysis on ongoing events, it allows users to engage directly with people who would otherwise be inaccessible, and perhaps it does sometimes direct people to good quality information they wouldn’t otherwise see. At the same time, it’s the venue for the least pleasant interactions in my life and it’s a repository of almost limitless idiocy and unkindness.

I have resolved for now to “cut off the time wasters quickly. They can’t be won over and whatever value there is in publicly refuting their arguments doesn’t justify the time and stress commitment”. There’s really no alternative strategy possible, since the platform is so full of people who (a) aren’t debating in good faith (b) can never be convinced or won over and (c) only get nastier with repeated interaction. They can take decades of meticulously collected, analyzed, and reviewed scientist and ‘refute‘ it with a silly accusation about the scientist or the person referencing them, a conspiracy theory, or an disreputable source which is nonetheless equally accessible online. Maybe very early on engaging with them helps draw some of the undecideds who are silently observing toward well-supported beliefs, but that almost certainly ceases to be true once your back and forth with that person has become one of your top ten present-moment sources of annoyance and irritability.

Our appalling legacy

There’s another dire warning from the IPCC: Final call to save the world from ‘climate catastrophe’

There seems little reason to hope that people will react differently to this one than to the 1990, 1996, 2001, 2007, and 2014 reports.

Our collective future is a massive ethical blindspot. People who wouldn’t think about missing a pension contribution or not enrolling their kids in an enriched learning program are collectively deciding by default to ravage the planet which we all depend on, and our political and economic institutions are acting almost exclusively to encourage that outcome.

The right’s anti-carbon-tax hostility

A carbon tax is a liberty-respecting, economically efficient mechanism to help address the threat of climate change and build a sustainable, prosperous society. It ought to be welcomed and supported by policy-savvy fair-minded conservatives who want to live up to their ideals while stewarding the integrity of the planet for future generations.

Conspiracy theories among climate change activists

Climate change activists often (plausibly) assert that “the science is settled” and present themselves as the informed contrast to people whose lack of scientific understanding or manipulation by fossil fuel actors has left them with the false belief that climate change isn’t happening.

At Toronto’s smallish Rise for Climate march on Saturday, I saw at least four people who were trying to convince people that chemtrails from aircraft are actually secret nefarious geoengineering by governments. Along with a large banner with pictures of aircraft chemtrails and frightening claims, they were distributing a colour handout:

It’s a bizarre document. It claims that chemtrails (themselves a conspiracy theory that has been around for many years) are a secret “form of climate change mitigation” via solar radiation management (SRM). It also claims, however, that “SRM aerosol cloud canopies trap more heat than is deflected by SRM programs”, so the supposed chemtrail program actually makes climate change worse. It also claims that along with the chemtrails “associated microwave transmission atmospheric manipulation” is “decimating the ozone layer”. It’s a fever dream re-interpretation of contemporary environmental politics, marrying an old conspiracy theory with new concerns about the real potential technology of geoengineering by solar radiation management. They throw in that the geoengineering chemtrails cause autism, along with allergies and dementia, and claim that the program “was fully deployed immediately after WWII”.

It’s crazy from top to bottom, from the claim that the secret program is somehow “illegal” to the contradictory claims that the program is “officially denied” but also that there are “countless official documents which confirm” it. It’s also a bit ironic given how self-conscious the public conversation about geoengineering has been, including about whether any sort of testing could produce unwanted side-effects and how any geoengineering ought to be governed.

When you lose trust in formal sources of information like governments and scientific bodies, it becomes impossible to have an informed position on climate change. The internet is full of nonsense, as everyone expects, and the environmentalist movement includes many who are highly credulous when it comes to claims that they are inclined to believe, whether those are about health and nutrition or about government conspiracies.

What it’s like to hear but not see the Toronto Air Show

A tweet of mine, written in a moment of irritability aggravated by the sound of jets roaring overhead, has gotten some attention by virtue of being incorporated into some news articles about social media commentary on the Toronto Air Show.

In addition to my standard gripes about the wastefulness of jet engine use, the undesirability of unwanted background noise, and the militarism embodied in combat aircraft development, I suggested that there are people in Toronto who find the experience of being a bystander during the noise as troubling or a reminder of trauma, having heard military jets operating at close quarters during any number of recent conflicts, from Gaza to Afghanistan to Yemen, or during interception flights carried out by domestic air forces.

A disturbing amount of the response on Twitter expressed anti-immigrant sentiment, particularly an assertion that (a) people who have experienced conflict and now live in Toronto now live in preferable life circumstances and therefore (b) they owe certain moral obligations to people who previously lived in the place they now inhabit, to wit just lumping it and not complaining while these acrobatic displays are put on. To some extent my interpretation of the comments was inevitably coloured by Twitter’s reputation as an especially hostile and personal platform, but I think even when viewed with as much objectivity as can be mustered they brought unnecessary hostility to a discussion ultimately about public policy, specifically whether such spectacles should continue.

It’s entirely fair to criticize me for assuming what somebody else’s life experience would mean, in terms of their experience of these noises. That being said, the basic parameters of something like post-traumatic stress disorder are publicly known and it seems plausible to me that anyone who has traumatic memories of being close to combat in which jets operated (whether as a soldier or a civilian) would have some chance of being triggered by the sound of an air show. Given the population of Toronto, it’s plausible that hundreds of people with PTSD are within earshot of each loud noise made by flying aircraft. It’s much more speculative, but I have also wondered about the number of people who can have panic attracts triggered by a stimulus like a jet engine sound find it triggering due to associations they have made through fiction, specifically quasi-realistic military computer games and films which realistically depict violence like Saving Private Ryan. Statistically very few people, even during times of mass conscription, faced intense combat of the kind depicted in the film, but probably a majority of the adult population has now seen multiple detailed immersive representations, whether through films like Spielberg’s or depictions like HBO’s Generation Kill or Band of Brothers.

I don’t want to suggest that it’s the same thing at all, but I have my own negative associations with hearing but not seeing military jets at low altitude nearby, as I lived in North Oxford within earshot of at least some of the approaches to RAF Brize Norton and we used to listen to Vickers refuelling aircraft and B-52s flying in at all times of day and night (familiar eventually in their shrieks and rumbles) and speculate about whether they were coming back from Iraq or from Afghanistan, maybe carrying coffins.

I don’t think social media griping is going to lead to the abolition of the airshow, but I do think it’s a good thing to have a public dialog about what people in the city are going through in terms of their mental health and the choices we make together affecting it.

Australia’s climate change vulnerability and inaction

You would think a country where the entire state of New South Wales, responsible for a quarter of their agricultural output, is currently in drought and where water scarcity threatens their long-term viability as a country wouldn’t be such a climate change villain. Their wildfires keep worsening and their most important river is drying up. Alas, as with Canada’s oil-selling obsession, Australia seems more concerned about selling as much coal as possible to China as with maintaining a habitable continent.

Even without factoring in such exports, their emissions of greenhouse gas pollution have been steadily rising since 2013 after a period of general decline going back to 2005. Perhaps that’s unsurprising as they repealed their carbon tax in 2014.

This ties into a frightening possibility: as the most vulnerable rich countries are hit harder and harder by climate change they may not draw the lesson that international cooperation is necessary, retreating instead into self-defeating selfishness.

Suspension of disbelief and Westworld

The suspension of disbelief has a particular peculiar character within the science fiction genre. While there is certainly sci-fi that rejects all standards of realism rooted in actual science, and which might thus be better seen as a kind of fantasy with technology, most sci-fi seeks to imagine things that could be possible in the real universe, at least if the requisite technologies and aliens show up.

When experiencing science fiction, I find myself always cataloguing two kinds of consistency and places where each breaks down. First there is consistency within the world established by the narrative. If the robots in chapter one can be easily fooled by colour photocopies of people’s faces it shouldn’t change for no reason in chapter two. In a broader sense the internal rules of the universe should be consistent. If multi-year travel times between settlements are a major part of a fictional universe, the economic and political life of the settlements should be compatible with that. The second kind of consistency is with the known rules the real universe follows. This is routinely violated by sci-fi with comic book or action hero physics, where the capabilities of technology depend on the emotional stakes and the needs of the plot, rather than serving as a template for what the characters are free to do.

I have watched the first two seasons of Westworld with both kinds of consistency in mind and have been much more frustrated by internal inconsistency than by straight-up scientific impossibility. Perhaps with the big exception of “what powers the hosts?” the show doesn’t pose many straight-up problems of practicality. Rich and determined enough people could do most of what has been depicted so far (ignoring the question of whether copying and creating conscious beings is possible as depicted). Since a lot of the show is shoot-em-up gore, perhaps the most frustrating internal inconsistency regards what it takes to actually kill the robots (called “hosts”) and specifically why damage to their physical bodies can in any circumstance damage the small protected orbs which are supposedly their brains.

It makes sense in the emotional and Western contexts that one well-placed bullet brings down anybody, but it doesn’t make sense anymore when the constraints that are supposed to make the durable, re-usable robots into suitable targets are no longer being applied, and especially when some robots just shrug off bullets now because they have been reprogrammed. We’re two seasons in and everybody is still being killed because their tougher-than-humans replaceable bodies get damaged in ways that would make a person bleed to death or otherwise no longer be able to keep vital organs functioning.

Probably the writers have an answer or will roll one out subsequently, while most fans will put it down to the rule of cool on the basis of wanting to see more human-style gunfights between the robots. To me it comes across as unsatisfying, however, and a failing or unwillingness to think through the implications of the premises which the writers have already established. They’re taking a lot of the Ghost in the Shell universe where “bodies are a dime a dozen”, but sticking with gunshot wounds as a mechanism to sometimes-permanently sometimes-temporarily kill robots. The inconsistent treatment of guns is unsatisfying in other ways too, like how apparently there was some system built into the park to keep real guns from injuring human guests (suggesting some omnipotent operating system controls everything in the park) but which one person then shuts down in only that very limited way. The way they control explosives doesn’t make sense either, with the control room approving one explosion specifically for an important guest, but robots apparently playing with real nitroglycerin in several of the park’s programmed narratives. If guests are interacting with real wagonloads of nitroglycerin, how do they not get routinely blasted to pieces? And if the park can control how badly humans versus robots are hurt by nitroglycerin explosions, why don’t we see the evidence of that kind of control in other places?

It’s basically standard in fiction that characters important to the plot are impossibly competent with their weapons, while anyone attacking them is impossibly incompetent (like the much-mocked stormtroopers in Star Wars), but this is taken to an implausible degree when a single person with an antique pistol kills whole squads of mercenaries with submachine guns before any of the mercs can notice what is happening and use a weapon.

Science fiction is meant by many authors as a means of exploring philosophical ideas, as well as the implications of technology, and allowing inconsistencies and implausibilities may be intended to serve that purpose. That’s fine as far as it goes, and it’s not for me to tell authors what plot contents are or are not appropriate in their creations. Still, to some degree the task of creative worldbuilding depends on the contents holding together with each other and when that common basis is eroded by inconsistent treatment it diminishes the plausibility and immersiveness of the entire world.
