To Fix The Climate, Tell Better Stories

Nautilus - Michael Segal*

The missing climate change narrative. 

Here are two sets of statements from far-distant opposites in the climate change debate.
The first is from Naomi Klein, who in her book This Changes Everything paints a bleak picture of a global socioeconomic system gone wrong: “There is a direct and compelling relationship between the dominance of the values that are intimately tied to triumphant capitalism and the presence of anti-environment views and behaviors.”
The second is from Larry Bell, professor of architecture and climate skeptic, whom Klein quotes in her book. He argues that climate change “has little to do with the state of the environment and much to do with shackling capitalism and transforming the American way of life ...”.
Let us put aside whether we agree or disagree with these statements or are offended by them. What concerns us is their scope: Both attach a breadth of narrative to climate change that far exceeds what is, at base, a relatively well-understood set of climate mechanics (human-produced carbon emissions are changing the composition of our atmosphere and warming the planet) and a well-developed set of solutions (renewable and possibly nuclear energy, efficiency improvements, consumer education, and the appropriate pricing of carbon).
Each side of the climate debate accuses the other of exaggeration and suffers from its own. Skeptics ignore basic climate facts and perils, while those who point their  finger at capitalism itself discard one of the best tools at their disposal. It is in part market forces, after all, that have produced a thousand-fold reduction in the cost of solar power over the past three decades (guided by policy).

There is a swirl of other, orthogonal narratives, too. American conservatives worry about global agencies interfering in domestic affairs. Some Europeans mistakenly dismiss climate change denial as uniquely American: In December of 2015, Richard Branson told CNN that skepticism is not something he has to deal with in Europe, despite the fact that the percentage of people who believe climate change is caused by human emissions is higher in the United States than in the United Kingdom.1
The climate conversation can sometimes feel like a shouting match in a roomful of children wearing earplugs. Each narrative doesn’t just oppose the next but is deeply incompatible with it. Partly this is a natural result of what is at stake. But it is also because something is missing. We have allowed our political, national, economic, and cultural narratives free play in the modern climate change debate. But where, in this shouting match, are the narratives from science itself? Where is the science teacher?
Peter Sheridan Dodds has a nickname for us humans: Homo narrativus. Dodds, a professor at the University of Vermont, uses mathematics to study social networks. He has argued that people see the stories of heroes and villains, where there are really just networks and graphs. It’s our desire for narrative, he says, that makes us believe that something like fame is the result of merit or destiny and not a network model quirk.
That we love heroes is something we can all intuitively understand. Less obvious is that climate, too, has a considerable narrative weight and is something we understand through storytelling. “Climate cannot be experienced directly through our senses,” writes Mike Hulme in his book Why We Disagree about Climate Change. “Unlike the wind which we feel on our face or a raindrop that wets our hair, climate is a constructed idea that takes these sensory encounters and builds them into something more abstract.” That abstraction has a moral and a historical quality: from the portrayal of flood myths as part of our relationship with the divine, to the birth of fictional monsters like Frankenstein in the wake of climate events, to our association of storms and earthquakes with emotional states—climate has always been more than a mathematical average of weather. In fact, Hulme says, it is only recently, and primarily in the West, that the cultural and physical meanings of climate have become so separated.
There’s no doubt that climate change presents a real and severe danger.
That separation has contributed to a narrative vacuum—and, like nature itself, people abhor a vacuum. We fill it with the narratives we have at hand, even if they are powerfully at odds with each other. This goes some way to understanding the vitriol of the climate debate. “The ideological freightage we load onto interpretations of climate and our interactions with it,” writes Hulme, “are an essential part of making sense of what is happening around us today in our climate change discourses.” Stories about the virtues and evils of capitalism, the role of divine control, nationalist values, and so on, are not so much maliciously inserted into what could be a sober conversation but are an inevitable response to a story that is incomplete without them.
Faced with an absence, we revert to old narratives, and there are few older than utopia and dystopia. The skeptic storyline of the rise of a dictatorial world government usurping American values must be considered not as a unique reply to climate change but as the latest instance of a well-established dystopic trope, stoked by the climate narrative vacuum. Something similar can be said for attacks on the capitalist enterprise from the left. The public, for its part, is served visions of an apocalyptic future, whether it’s from politicians or from Hollywood—and, simultaneously, the utopianism of far-distant science fiction, which as a category is consumed in greater quantity than science journalism and which reflects and encourages what sociologists call “optimism bias” or “technosalvation.” These utopian instincts are strengthened by a historical data point obvious to all: Our species has survived every obstacle we’ve encountered, and we are still here.
Utopia and dystopia can reach even the highest levels. From the White House are echoes of dystopian claims that climate change is a hoax orchestrated by foreign powers. And Mattias Hjerpe and Björn-Ola Linnér, from the Centre for Climate Science and the Department of Water and Environmental Studies at Linköping University, in Sweden, point out that utopian elements can regularly be found in planning documents of the Intergovernmental Panel on Climate Change (IPCC), a United Nations body. The IPCC’s special reports on emissions scenarios, for example, “all envision a radical narrowing of global income gaps between rich and poor countries. This vision is outright utopian thought.”2 Not only has the per capita income gap between rich and poor countries grown over most of the past three decades, but the economic development required for a significant narrowing of the gap seems at odds with the IPCC’s own sustainability goals. That, say Hjerpe and Linnér, “is utopian in the sense that it is not a projection based on current trends, but rather an extrapolation of current policy goals.”
Both dystopian and utopian narratives have their own rationales and evidentiary support, and there’s no doubt that climate change presents a real and severe danger. But in the public realm, these types of narratives also have a tendency to be useless. They leave the public spectating a stalled debate between extremes and generate ample motivation to check out.
This is not to say that the climate conversation is irreparably broken. It’s true we can’t take away those unhelpful narratives that have already been attached to it. But we can add new ones, and some narratives are more powerful than others. Scientific narratives, if they’re done right, are some of the most powerful of all. They teach us more than facts, mechanisms, and procedures. They convey a worldview of skeptical empiricism and indefinite revision, show us how to negotiate the boundary between our rational and emotional selves, teach us to suspend judgment and consider all the possibilities, and remind us that a belief in objective truth is a deep kind of optimism with massive dividends. Perhaps most important of all, they situate us in the world.
The successful assimilation of broad narratives from astronomy and genetics reminds us how powerful science narrative can be. We think of ourselves today as genetic machines, carrying around an adaptive program, which we inherit and pass on, doing so on this one habitable planet among countless others in a universe with a finite age. These facts have become intuitions and a part of our identity. The goal of climate change coverage should be a similar creation of intuition from fact. Intuition that our planet is a dynamic thing, that its environment is highly interconnected, that it has been remade many times by things living and dead.
Are we getting that done? The media has communicated the basic facts behind climate change well enough: the famous line graph of rising carbon dioxide levels, the 300 parts per million line in the sand, the northward migration of adapting species, and the endangerment of those left behind. But the narrative around these facts is more obscure. In the words of social scientists Susanne Moser and Lisa Dilling, science communicators “often assume that a lack of information and understanding explains the lack of public concern and engagement, and that therefore more information and explanation is needed to move people to action.”3 Many of these facts are, by now, either uncontested or unsurprising. It is the narratives around them that are missing.
NOT SO FAST: National narratives can obscure climate debate, as when Richard Branson incorrectly suggested that climate change skepticism is less prevalent in the U.K. than in the U.S. Wikimedia Commons
Kirk Johnson, director of the Smithsonian National Museum of Natural History, puts it this way: “If you look at how the media treats scientific discoveries, they’ll go to the wonder. ... [They’ll say] ‘here’s this thing that’s been discovered,’ not the process of how we figured it out. And I think that understanding of how we know what we know is so critical ... If you don’t help people understand what those processes are, [if] you just say ‘here’s the answer,’ now they can go onto the web and dial up an alternate answer. I think we’re seeing an erosion of credibility of science to the public because of this huge flood of technology and information.”
This erosion is essential to understanding the modern climate debate. In the words of the philosopher Richard Rorty, “We understand knowledge when we understand the social justification of belief, and thus have no need to view it as accuracy of representation.”4 In the absence of social justification, the public ends up being called on to be the judge of accuracy of representation—in other words, of scientific content. Sure enough, quasi-scientific arguments based on misinterpreted data fragments abound in the skeptic community.5 Why did temperatures stay flat during World War II, despite an emissions increase? Was there an 18-year hiatus in temperature rise? The only reasonable answers to these questions lie with the scientific community, but they will be ignored if that community hasn’t earned an authoritative public voice. That is especially true when the answer is, “We’re not sure yet.”
Faced with an absence, we revert to old narratives, and there are few older than utopia and dystopia.
The question of authority is complicated further by the multidisciplinary nature of climate change. Authority within the sciences revolves tightly around narrow silos of expertise. As the academics Simon Shackley and Brian Wynne put it, “A common response by scientists to challenges to their authority is to demarcate the realm within which their expertise is autonomous.”6 In other words, there is a retreat to the silo. But at the policy level, climate change involves atmospheric chemistry, plant and ocean biology, solar physics, geochemistry, soil science, and glaciology, among other disciplines. Building authority in climate science is therefore not well served by the tendency of the scientist to retreat to home turf. Here, too, narratives can help.
Even scientists need to lure each other with narratives. The philosopher Rom Harré offers up that pillar of modern professional science, the scientific paper, as exhibit A. He argues that the three-part structure of the typical paper (hypothesis, results, and inductive support) is a post facto interpretation: “Anyone who has ever done any actual scientific research knows that this is a tale, a piece of fiction. The real-life unfolding of a piece of scientific research bears little resemblance to this bit of theatre.”7 Speaking as both a former scientist and a former academic editor, I can attest to the truth of this statement. From the lab to the publisher’s desk, narrative is constantly helping to organize, sell, and drive science. As Harré puts it, “Science must present a smiling face both to itself and to the world.” If narrative is necessary for one scientist to convince another of his or her result, it’s certainly necessary to engage and convince the public.
The narrative questions around climate change are broad. What does it mean for there to be a scientific consensus? How is the scientific method properly applied to a system that resists experimentation? What does a complex system look like? What is the nature of risk and probability? Each has a direct bearing on the climate change conversation without necessarily being about climate change. They, and others like them, constitute a suprascientific narrative that is necessary for science to become culture. In a way, every good science story is a story about all of science and helps us understand every other science story.
So let’s tell more of them.

US Military Taking Climate Change Into Account In Food And Energy Security

Increasing tensions between the United States and Russia over Syria in recent days may have many implications but they also have many causes, including the impact of climate change on food and energy security around the world.
Sherri Goodman, a former deputy under secretary of defence for environmental security in the US, says the US military now regards climate change as one of the biggest long-term security threats and is building it into strategic considerations and logistics planning.
As the biggest user of oil and gas in the US, the aggressive shift of the US military to more renewable forms of energy is playing a huge role in the reorientation of the US economy to using less fossil fuel, she says.
Climate change-induced drought has been linked to many of the uprisings that have broken out across Africa and the Middle East in recent years, including the Arab Spring and the conflict in Syria as food pressures have made populations increasingly desperate.
But Ms Goodman points out that access to renewable energy – and less fossil fuel use – also has huge implications for national security.

Additional peril
Reliance on fossil fuels, she notes, invariably requires having to transport them. The more you have to transport fuels, the more costly the risks.
"It means putting ourselves at additional peril," she notes.
And the role of Middle East oil in determining the US geopolitical strategy is an obvious example of this.
Ms Goodman says challenges for the US military include the vulnerability of military assets themselves, such as naval bases that are at risk from rising sea levels and storm surges, as well as the fact strategic planning requires preparation for more global instability through crop failure or forced migration within and across borders, and spending more time and effort on disaster relief.
" The way it's been managed in the defence budget is that oil and gas is taken as an additional, huge cost on top of the normal spend," she says.
"They'd much rather that that money was available for equipment and personnel so that's become an incentive to innovate," she said.

Broader use of renewables
That can involve anything from solar-powered batteries for soldiers or micro grids at forward positions to broader use of renewables in defence establishments.
The US military has dedicated programs to try to deal with this growing strategic risk by investing in energy research, development and demonstration programs, and new technologies.
Ms Goodman says that, as in Australia, the climate change debate in the US is still "overly politicised, despite the science being abundantly clear".
However, she says climate deniers have shifted from denying climate change to arguing about how fast it is happening, thus introducing uncertainty into what to do about it.
But, she says, from the military's perspective, there is no opportunity to wait, likening it to being prepared for a threat of terrorism, weapons of mass destruction, or North Korea's nuclear capacity.
"You don't wait until you have 100 per cent certainty you are going to be attacked," she said.

World Must Hit Zero Carbon Emissions 'Well Before 2040', Scientists Warn

The IndependentIan Johnston

New research suggests it will be an ‘enormous challenge’ to prevent global warming getting out of hand

Humans must reduce net greenhouse gases emissions to zero “well before 2040” in order to ensure global warming does not go above 1.5 degrees Celsius by the end of the century, scientists have warned after carrying out a study using a sophisticated new computer model.
The analysis suggests that efforts to prevent temperatures rising to potentially dangerous levels may have to rely heavily on “negative emissions” technology that is still in its infancy.
Commenting on the study, Professor Richard Betts, head of climate impacts at the UK’s Met Office Hadley Centre, said the “important” research spelled out the “enormous challenge” ahead.
Under the Paris Agreement on climate change, the world committed to prevent global warming from going above 2C but also attempt to restrict it to as close as 1.5C as possible amid mounting evidence that dangerous effects could kick in sooner than previously thought.
The new study, described in a paper in the journal Nature Communications, is one of the first to use the new FeliX computer model, which includes social and economic factors along with environmental ones.
One of the researchers, Dr Michael Obersteiner, of the International Institute for Applied Systems Analysis near Vienna, said: “The FeliX model ... provides a unique systemic view of the whole carbon cycle, which is vital to our understanding of future climate change and energy.
“The study shows that the combined energy and land-use system should deliver zero net anthropogenic emissions well before 2040 in order to assure the attainability of a 1.5C target by 2100.”
This does not necessarily mean that humans would have to stop burning fossil fuels in little over 20 years, as the researchers included natural carbon sinks – such as forests – and the use of carbon-capture technology in their calculations.
So some emissions would be allowed, if enough carbon was taken out of the atmosphere by either natural or artificial processes.
In the Nature Communications paper, the researchers wrote: “Roughly speaking, and based on current technologies, energy sector emissions will need to peak within the next decade.
“By 2100, the market share of fossil fuels will need to fall to less than a fourth of total primary energy demand to preserve the possibility of meeting the [Paris Agreement] targets.”
They said “full decarbonisation” would probably have to rely on the combined use of carbon-capture technology, which is still being developed, and the burning of biofuels.
The idea is that trees and other plants would absorb carbon and then be burned in power plants with the emissions prevented from getting back into the atmosphere by carbon-capture, creating a giant machine to suck CO2 from the air.
However some doubt this will be possible on a scale large enough to have a significant effect, given the need to use land to grow crops and raise animals.
And the paper said: “If coupling of [carbon-capture-and-storage] technology with bioenergy production is ultimately found to be unfeasible, uneconomical or unacceptably burdensome on ecosystems, then alternative negative emissions technologies (for example, direct air capture) will need to be substituted.
“In the absence of these fail-safes, fossil fuels will need to be phased out completely and well before 2100.”
Professor Betts, of Exeter University, who has played a leading role in the Intergovernmental Panel on Climate Change’s work, said the research should help world leaders establish what they have to do.
“This important paper provides much-needed detail on how the countries of the world might meet their commitments under the Paris Agreement,” he said.
“It is clear that it is an enormous challenge, especially if we do not develop ways to remove carbon dioxide from the atmosphere and put these into practice.”
Gareth Redmond-King, head of climate and energy policy at conservation group WWF, said the paper showed just how pressing the need was to take action.
“Once again, climate scientists are sounding an alarm to remind us of the urgent need to act now to tackle climate change,” he said.
“Melting ice caps, dying coral reefs, plummeting wildlife populations, rising sea levels and extreme weather – they all get worse and worse as the Earth’s temperature rises.
“Similar analysis recently showed that, on current levels of emissions, we’ll have reached enough to warm by 1.5 degrees as soon as four years’ time!
“We know how to solve this problem – we have the technologies to provide clean electricity at a much greater scale than we’ve already achieved.
“And we know that reversing deforestation preserves a hugely important global carbon sink to absorb more of our emissions.  So what will it take to convince all the signatories to the historic Paris agreement that they need to act now?
“Here in Britain, that means we need the UK government to get their finger out and publish their now long-overdue Emissions Reduction Plan.  We need ambitious, robust, long-term plans to slash emissions and protect our environment.”
The Government has repeatedly delayed publication of the Emissions Reduction Plan, the key strategy that is supposed to lay out how the UK will reduce its production of greenhouse gases, even though there is a legal requirement to produce one. The ongoing failure to come up with a plan could ultimately lead to legal action against Ministers.
Bob Ward, policy and communications director at the Grantham Research Institute on Climate Change and the Environment, said he feared politicians would place too much store on the potential of carbon-capture.
“There’s a great danger that policymakers believe some of these targets are feasible to achieve, but without realising that it depends on the large-scale use of unproven negative emissions technology,” he said.
“It would be far more sensible if we were planning for the future on the basis we might not have that and therefore cutting emissions much more strongly in the short-term, rather than thinking we can do it in a more gradual way, then have suddenly a magic wand of negative emissions towards the end of the century.”
Mr Ward said the latest research suggested the 1.5C target was unlikely to be achieved. Last year temperatures were about 1.1C above pre-industrial levels, boosted slightly by the natural El Nino weather system.
But the world should still try to minimise the risks partly because of emerging evidence that a tipping point could be reached that would lock in sustained rises in sea levels, Mr Ward said..
“The work I’ve seen suggests it’s going to be near impossible to stay below 1.5C, but it might be possible to overshoot slightly then come back down within 50 years or so,” he said.
“It’s worth considering because there is modelling that suggests somewhere between 1.5C and 2C of warming we may pass a [sea level rise] threshold. If you go beyond 1.5C, and the closer you get to 2C, we would be seeing sea level rise continuing for many centuries and therefore result in very large accumulative rises.”
