(AU) Changing The Narrative Of Climate Change

Social identity, not scientific evidence, drives many people’s attitudes on climate change.

Few people would recognise respiratory failure as a critical threat to their health without also placing Covid-19 – an amplifier of respiratory failure – in the same category. Yet, this is essentially the way many Australians view climate change and its impacts, according to the 2020 Lowy Institute Poll.

While “drought and water shortages” and “environmental disasters such as bushfires and floods” are considered critical threats by 77% and 67% of the Australian population, respectively, only 59% say the same of climate change. We know that global warming is amplifying Australia’s risk of severe drought and bushfires along with other extreme weather events and rising sea levels. This disconnect presents us with a puzzle.



If we are fearful of those threats, logic would suggest we should seek to minimise them. The world’s best expertise has told us that if we want to minimise the threat of drought and bushfire, we need to take action on climate change.

Why, then, do we rate amplified symptoms as more threatening than the very causes for their amplification? Part of the answer lies in how we perceive threats. Humans are prone to appraising threats based on their availability to our minds, meaning we will rate threats we can perceive or recall as more urgent than those we cannot.

The ability to remember the experience of drought and bushfire, versus needing to imagine the nebulous and multifaceted climate change, is an important factor. We are not ideological partisans – we are expressive partisans seeking belonging and coherence with our identity group and cultivating points of hostility to and difference from outsiders.

But that’s not the whole story. For the vast majority of people in Australia, just as in many other nations, climate change is not an issue of science. Instead, climate change is a social object. As a social object, it is something we come to understand through our interactions in our social worlds and via observing discourse in the mass-mediated public sphere.

Climate change occupies our minds not as the latest synthesis of the best available evidence from the IPCC, but as a narrative about causes, effects and solutions produced by our conversations with family and friends, our observations of the media and politics, and our exchanges on social media.

The Lowy Institute Poll nicely illustrates archetypical climate narratives. If your climate narrative is “Global warming is a serious and pressing problem. We should begin taking steps now even if this involves significant costs”, chances are high you read the drought, fires, smoke and hail during the horror summer of 2019–20 as the latest chapter in Australia’s experience of the effects of climate change.

During the fires, it seemed there was no place left for narratives of climate action delay and science denial. But sure enough, those narratives emerged. The #ClimateEmergency narrative was challenged by the #ArsonEmergency, despite no evidence to support the latter.



Why were some Australians so eager to adopt the so-called arson emergency as their narrative explaining the fires? US political scientist Deva Woodly’s insights on resonance suggest a way to understand. By this concept, new information, if it is to stick and become part of our narrative, must resonate with what we already know – our “common-sense” understanding of the world.

If our common-sense understanding of the world is that “the problem of global warming should be addressed, but its effects will be gradual, so we can deal with the problem gradually by taking steps that are low in cost”, then the idea of the fires as a catalyst for revolution in Australian climate politics and policy is unlikely to resonate.

But the fires as a crisis spurred by individual bad actors probably will. And for those folks, the “arson emergency” narrative allows climate change to remain a comparatively minor threat, compared to the threats it amplifies, despite the horror fires.

We must also recognise that climate narratives are not randomly distributed across the Australian population. In Australia, acceptance of the reality of climate change divides along left-right political lines – the intensity of left-right political polarisation on climate change is second only to the United States.

So, our climate narratives are closely wrapped up not just in our social worlds, but also in our political worlds, and they come to be part of our identity. Our climate narrative signals the social groups to which we belong, just as our signals of social belonging can indicate our climate narrative.

For many people, climate narratives are far less connected to appraisal of the science of climate change than they are to expressing social belonging in relation to climate change. We are not ideological partisans – we are expressive partisans seeking belonging and coherence with our identity group and cultivating points of hostility to and difference from outsiders.

If we are to see better alignment between the best available scientific evidence and how Australians guage the threat of climate change to the nation’s interest, we have to recognise that climate narratives are deeply intertwined with our social-political identities. New understandings will only stick if they resonate with existing narratives. And existing narratives are most likely to change if led from within the identity group.

To that end, we can look to groups that are advocating for climate action from outside of the “usual suspects”, such as Farmers for Climate Action, the Investor Group on Climate Change, the Hunter Jobs Alliance, and the Blueprint Institute. These are the social spaces in which a reorientation of climate narratives may occur.

How Should The Media Talk About Climate Change?

It is now October of 2020, the homestretch or—God help us—the halfway point of the Donald Trump years. As we flip through our metaphorical national photo album, reminiscing on some of the all-time darkest moments, there are so many to consider. You’ve got Charlottesville, of course, with the marching Nazis holding tiki torches—Trump’s “very fine people.” The peaceful protesters being tear-gassed in front of St. John’s Church. The maskless superspreader event in the Rose Garden. One event that comes up less often is Trump’s California wildfire briefing, early last month. The West Coast was in flames. The skies above San Francisco were red. Smoke and ash blotted out the sun. And the President was on television assuring the public that “it’ll start to get cooler. You just watch.” He added, “I don’t think science knows” the truth about climate change.

Altogether, an extremely grim tableau. But among some environmental activists there was cause for celebration. For once, climate change had broken into the foreground of our insane news cycle. Within a week of Trump’s California visit, there was a pileup of evening TV news segments on the subject. “NBC Nightly News” did a piece about California climate refugees. CNN anchors interviewed the former California governor Jerry Brown about climate change and discussed Trump’s appointment of David Legates—a known climate-change denier—to lead the National Oceanic and Atmospheric Administration. “Frankly, it was better than anything I’d even dreamed,” the activist Genevieve Guenther told me recently, from her home in the West Village. “I’d been hoping the news anchors would mention climate change. But they didn’t just do that. They talked about it as the emergency that it is. And they gave their guests space to connect it to the Presidential elections and American politics, and even talk about some of the policy solutions.”

Guenther runs a volunteer group called End Climate Silence, which is focussed on combatting something more subtle than the aggressive climate denial espoused by Trump and his allies in government, or on Fox News: when news anchors or weather forecasters breathlessly cover an extreme-weather event—a hurricane, drought, forest fire, or heat wave—without ever mentioning the C-phrase. Instead, they’ll talk around it, using terms like “historic,” “unprecedented,” and “record-shattering.” According to Guenther, this silence is just as pernicious as denial. “There is a name for the unprecedented intensity and scale and relentlessness of extreme-weather disasters,” she said. “Climate change.” She added, “If you fail to mention that, it gives people the impression that it’s not happening—that these disasters are acts of God.”

Until recently, climate silence was the norm on television. In September, as the wildfires raged, the nonprofit group Media Matters published a study showing that only four per cent of ABC, NBC, and CBS news segments on the wildfires the month before had mentioned climate change. On September 10th, Guenther published an op-ed in the Boston Globe, citing another Media Matters finding that there had been a similar silence around Hurricane Laura. (Out of fifty network news segments on the storm between August 24th and August 27th, none had mentioned climate change.) “For too long, journalists have feared that reporting the links between extreme weather and climate change might expose them to the charge of liberal bias,” she wrote. “But the news media should not be influenced by such tactics.” She included data from a poll that her group had commissioned, showing that the majority of Americans—including the majority of Republicans—want the media to highlight connections between climate change and extreme weather. She promoted the findings on Twitter, where she has about thirty-four thousand followers.“I tweeted at the prime-time news shows’ producers and anchors. And I suspect that they did see it, just because of the dramatic shift in coverage,” Guenther said. Or the turnaround could have been driven entirely by Trump. “Whatever it was, I’ll take it.”

Guenther is relatively new to climate activism. Until recently, she was an English professor. She got her Ph.D. from Berkeley, in 2004, in Renaissance literature. Her first book, “Magical Imaginations,” analyzed texts by Spenser, Marlowe, and Shakespeare. (Renaissance Quarterly called it “sensible” and “brilliant.”) In 2010, she was teaching at the University of Rochester, where she had a tenure-track job. But she and her husband, a software engineer, had a baby that year, and, as she spent her maternity leave at her apartment, something gradually shifted. Studying Renaissance literature began to seem less important. So did commuting between the West Village and Rochester. Her husband worked at Google, so they didn’t need the money. “I just couldn’t do it,” she said.

She quit her job, stayed home, and planned to write a book on Shakespeare. She spent hours nursing her son while scrolling through the Times on her phone. “For the first time in my life, I started really reading the newspaper,” she said. She lingered on the Science section. “The stories about climate change really stuck with me, and started to make me anxious,” she explained. “The articles were saying that all these terrible things are going to happen by the year 2100 if we do not bring our emissions down to zero.” Equatorial cities exposed to furnace-like heat. New York, London, Mumbai, and Shanghai subsumed by the sea. Wars in India and China as three billion people fight over water from the evaporating Himalayan glaciers. Refugees flooding into southern Europe, which will itself be struggling with food shortages and drought. All these events are predicted to happen if the world is allowed to heat up by three degrees Celsius by 2100—which, mind-bogglingly, it will do if countries merely keep to the pledges in the Paris climate accord. (And no major country is on track to do even that.) “My son was born in 2010, and I knew that his life was going to play out across the twenty-first century. That meant he would see these predictions,” Guenther said.

She put aside Shakespeare and started enrolling in online climate-science courses. Then, in 2017, came an event that radicalized her: the Times hired Bret Stephens, a former Wall Street Journal columnist with a history of questioning climate science, as a writer for its Opinion section. Guenther was outraged. “I thought I could trust them to understand the gravity of this, and not imagine that climate denial was a legitimate position in 2017,” she said. She started an online petition calling for Stephens to be fired. It didn’t work, but Guenther came to the attention of a group of climate scientists who are active on Twitter, including Michael Mann, Peter Kalmus, and Gavin Schmidt.

Guenther began to think that she might have something to contribute to the dialogue. “In Renaissance literature, there’s a rhetorical principle called energia—energy or vividness,” she said. “It means that, if you’re trying to persuade your reader, you need to give them vivid images that will capture their imaginations.” She found most “climate communications” to be energia-deficient. “It was too data-driven and abstract. It would talk about ice and the sea and polar bears—none of the things that made it urgent and personal to me.” Instead of the Shakespeare book, she began writing a book about what she calls “the language of climate change.” It analyzes common words and phrases in the field, arguing that many of them are counterproductive, “misrepresenting the problem and biasing us against the solutions.”

Researchers such as Naomi Oreskes have documented the ways that, over the years, fossil-fuel interests have weaponized the notion of “scientific uncertainty” to manipulate public opinion. In one chapter, Guenther focusses on the word “uncertainty” itself. “For normal people, you hear ‘uncertainty’ and it suggests that you don’t know something,” she explained. “But in climate science ‘uncertainty’ basically means a range of possible outcomes. As in, ‘The uncertainty interval is from 1.5 degrees Celsius to three degrees Celsius.’ The synonym for that is confidence.”

She also dislikes the word “consensus”—as in “the scientific consensus on climate change”—because it gives rise to the vaguely conspiratorial image of a group of scientists getting together and coming to an agreement. “In science, consensus doesn’t refer to a discussion,” she said. “It means knowledge that arises from independent research projects which all achieve the same results.” She prefers the term “discovery.” And she takes issue with the ubiquitous “we,” as in, “We could have stopped climate change in the nineteen-eighties.” “You think this little pronoun is so innocent, but it actually obscures the political reality of the whole problem,” she said, bringing up the vast differences in the carbon emissions of rich and poor countries, and the role of the fossil-fuel industry in blocking solutions. She has written that, instead of thinking of climate change as something that “we are doing,” most people should think of it as “something we are being prevented from undoing.”

Guenther was carving out a niche for herself discussing these ideas in panel appearances and on Twitter, when, in the summer of 2018, she spent a morning stuck in traffic, listening to public radio. In the course of three hours, she listened to three stories: a segment about catastrophic flooding in Japan; an interview with a cattle rancher in drought-stricken Oregon; and an interview with a French-Moroccan futurist. “He was praising the idea of covering the planet with rivers of driverless cars—without ever discussing the fact that we need to entirely electrify our transportation system within the next thirty years in order to hold warming at two degrees Celsius!” Guenther said. She went on, “These three stories were clearly about climate change, but the announcers never even mentioned it once. And this was NPR! I felt like I was in some horror movie where I knew something terrible was happening but everyone was going about their lives in this surreal, almost zombified fashion.” She wrote a rant about the experience on Twitter, where it sparked a discussion among journalists. A couple weeks later, the MSNBC anchor Chris Hayes was weighing in on the subject, writing in a tweet, “Almost without exception. every single time we’ve covered [climate change] it’s been a palpable ratings killer. so the incentives are not great.” Guenther suggested that, instead of doing segments focussed on climate change, he should make an effort to mention it in the coverage he was already doing. Hayes replied, “That I agree with and it’s something we do.”

Over the past few years, environmental activists have taken on the news media intermittently. There have been protests in front of the headquarters of Fox News and the New York Times. The climate group 350.org, which was co-founded by the New Yorker writer Bill McKibben, marched into Times Square in 2012, as Hurricane Sandy sped toward New York City, and unfurled a parachute that said “End Climate Silence.” “It’s important, because you see from polling that one of the greatest predictors of people’s belief in global warming is how much they hear about it. There’s not a magic set of words,” Jamie Henn, a 350.org co-founder who now runs a group called Fossil Free Media, said. “We often see that, especially for TV, you get more coverage on climate when people complain about it.”

But, for the most part, these initiatives were pushing news organizations to cover climate change directly. Guenther wanted them to mention it in their existing coverage, “so people understand that this is not just a science or environmental story—this is the increasingly pressing context for stories about extreme weather, energy, business, finance, real estate, politics, food, travel, and even the arts.” To that end, she set up End Climate Silence, which consists of herself and two volunteer researchers. (The group also has a four-person advisory board, which includes the climate scientists Mann and Kalmus.) The volunteers comb through newspaper reports and transcripts of TV news programs, flagging instances of “climate silence.” Then Guenther engages in “direct outreach,” e-mailing journalists, producers, and television anchors, and pressing them to improve. If they ignore her, she engages in “external pressure”—basically, shaming them on Twitter. “It’s really the public square for people who work in media,” she said. The group’s account, @EndClimtSilence, has almost ten thousand followers.

The strategy has worked with print journalists, Guenther said: “They listen to their critics. I think it’s because they really care about their writing.” TV news people have been less responsive. “They don’t care about me,” she said. “And, I realized, they don’t care about being shamed. They’re shameless as it is. . . . They only care about ratings.” That’s why she’s recently shifted her tactics, putting a greater emphasis on public polling, to emphasize viewer interest.

This past week, Guenther said, the sea ice in the Arctic was struggling to refreeze—another scary feedback loop. Hurricane Delta left hundreds of thousands of people without power. There were ongoing wildfires in California, and in Argentina, Brazil, Paraguay, Bolivia, southern Turkey, and parts of Syria. And we just had the hottest September on record. But Guenther was focussed on the next Presidential debate. She’ll be watching to see which questions about climate change the moderator, NBC’s Kristen Welker, poses to the candidates. She was pleased that climate change had come up during the Vice-Presidential debates, though she wished the moderator hadn’t framed the question as whether Pence “believed” that man-made climate change was making extreme weather worse. “It’s not the Tooth Fairy or Santa Claus. The question is: Do you ‘understand’ or ‘accept’ climate science?” she said. Anyway. She added, “The work goes on.”

Ancient Humans’ Demise Could Foreshadow Our Own Species’ Extinction

Inverse  - Sarah Wells

This fossilized horror story is unnervingly modern.



One Earth
At least six different Homo species populated the World during the latest Pliocene to the Pleistocene.

The extinction of all but one of them is currently shrouded in mystery, and no consistent explanation has yet been advanced, despite the enormous importance of the matter.

Here, we use a recently implemented past climate emulator and an extensive fossil database spanning 2,754 archaeological records to model climatic niche evolution in Homo.

We find statistically robust evidence that the three Homo species representing terminating, independent lineages, H. erectus, H. heidelbergensis, and H. neanderthalensis, lost a significant portion of their climatic niche space just before extinction, with no corresponding reduction in physical range.

This reduction coincides with increased vulnerability to climate change.

In the case of Neanderthals, the increased extinction risk was probably exacerbated by competition with H. sapiens.

This study suggests that climate change was the primary factor in the extinction of Homo species.
We Homo Sapiens are just one of six different human species that have populated the world through history.

And while evidence abounds regarding what prompted the demise of our closest relative, Neanderthals, what caused the downfall of the other four species remains largely a mystery.

New data suggest these ancient humans may have met a very modern end: climate change.

In a new study published Thursday in the journal One Earth, scientists present a new analysis of the fossil record using climate modeling.

They propose a new theory to explain these hominids' extinction: that the disintegration of ancient humans' climatic niche was a huge driver in their subsequent eradication from Earth.
"They tried hard; they made for the warmest places in reach as the climate got cold, but at the end of the day, that wasn't enough."
Previous studies of ancient human extinction have largely focused on Neanderthals' competition with early Homo sapiens, but there is relatively little research into what may have spurred the downfall of other, more ancient hominids, including H. erectus and H. heidelbergensis.

"[T]he fate of our ancestors is made even more important by the current, ever-increasing pressure that rapid and extreme climate change will continue to put on our own species," the scientists write in the study.

Climate change is very much a modern problem, but in the ancient Pliocene and Pleistocene — the periods when these human species roamed — Earth's climate also experienced dramatic temperature swings. Notably, the last Ice Age falls right between these two eras.

By comparing both the fossil record of these ancient human species to climate models of the time, the researchers found clear evidence that extreme changes in climate were linked to these ancient humans' demise, Pasquale Raia, the study's first author and associate professor at University of Naples, said in a statement.

"[D]espite technological innovations including the use of fire and refined stone tools, the formation of complex social networks... past Homo species could not survive intense climate change," Raia said. "They tried hard; they made for the warmest places in reach as the climate got cold, but at the end of the day, that wasn't enough."

The fossil record

To understand what the world may have looked like for these ancient humans, Raia and his colleagues used a high-resolution climate emulator, capable of calculating the rainfall, temperature, and other data from the past five million years.

They combined this massive data set with 2,750 archaeological records. By pairing these two different streams of data, the researchers were able to reconstruct what a "typical" environment looked like for these ancient humans, as well as the dramatic climatic changes that would have been cause for alarm.

Homo erectus, for example, was at home in tropical areas of South East Asia, so the group was well-adapted to warmer climates. This species' extinction took place during the last glacial period, which would have created a much colder climate than that in which they evolved to thrive in.
"Climate change made Homo vulnerable and hapless in the past, and this may just be happening again." 
By tracing the overlap between when a specific species went extinct and dramatic climate events, the researchers saw a clear pattern: extreme changes in climate were closely linked to subsequent extinction.

"We were surprised by the regularity of the effect of climate change," Raia said. "It was crystal clear, for the extinct species and for them only, that climatic conditions were just too extreme just before extinction and only in that particular moment."

The researchers also discovered that Neanderthals were not immune to such effects on climate. Rather, they suggest that extreme climate, as well as competition with Homo sapiens, may have led to their extinction, too.

An ancient warning

While the environments of our ancient relatives were different to our environment now, the researchers note this climate history serves as a stark warning for our own future.

"It is worrisome to discover that our ancestors, which were no less impressive in terms of mental power as compared to any other species on Earth, could not resist climate change," Raia said. "I personally take this as a thunderous warning message. Climate change made Homo vulnerable and hapless in the past, and this may just be happening again."
