Climate Crisis: Rising Sea Levels And Catastrophic Storm Surges Could Displace 280m People, UN Warns

The Independent - Harry Cockburn

IPCC draft report is fourth to call for radical action to tackle environmental disaster

The damage caused by catastrophic “superstorms” combined with rising sea levels could increase by a hundred-fold or more, displacing hundreds of millions of people from coastlines around the world unless more is done to limit greenhouse gas emissions, according to a draft report by the United Nations.
According to French news agency AFP, which said it had obtained a copy of the report, the document outlines a grim scenario in which the warming oceans are “poised to unleash misery on a global scale”, with declining fish stocks, the melting of sea ice and glaciers, and increasing levels of human displacement.
Unless there are serious cuts to man-made greenhouse gas emissions, at least 30 per cent of the northern hemisphere’s surface permafrost could melt within just 80 years, the report warns.
This melt would unleash billions of tonnes of carbon stored in what are currently permafrost areas, which will accelerate rates of global warming even more.
The upshot would be warming seas and rising coastlines, which could immediately threaten 280 million people, the document says.

The findings come from the UN’s Intergovernmental Panel on Climate Change (IPCC) and is a “special report” on oceans and the Earth’s frozen zones, known as the cryosphere.
It is the fourth report in the last year to be published by the organisation examining the impacts of the unfolding climate crisis, with the other three examining issues including declines in biodiversity, forest management and food, and how the effects of a 1.5C increase in average global temperatures since pre-industrialisation will be felt.
All of the reports warn major change is required to avert disaster.
The warning comes as MPs and scientists have warned the UK is already on track to miss its environmental goals, including a government pledge to reach net zero emissions by 2050.
Last week a report from the Science and Technology Select Committee said efforts to reduce emissions have been undermined by “unacceptable” cutbacks and delays, meaning we face “dire consequences”.
And on Thursday, the government’s chief environment scientist said the UK cannot hit its net zero emissions goal while ministers are fixed on economic growth as measured by GDP.
Globally, many countries are also dragging their heels on putting policy in place to tackle emissions.
The US – the second biggest contributor of CO2 – is exiting the Paris agreement on climate change, under Donald Trump’s leadership.
China – the world’s biggest polluter – is making strong progress in renewable technologies, but has relaxed air pollution controls and coal use is creeping upwards.
In India, an enormous drive to open coal power plants is underway, though the country is also increasingly relying on solar-generated electricity.
And in the EU, progress towards a mid-century net zero goal is slow due to some member states’ reluctance to vote for policies legally requiring them to reduce emissions.
The Paris agreement called on all countries to work to ensure average global temperature rises remain “well below” 2C warmer than the world was before the industrial revolution.
Michael Mann, director of the Earth System Science Centre at Pennsylvania State University told AFP one of the key problems was the idea humanity can overcome any problems resulting from sea-level rises.
“There is a pervasive thread in the US right now, promoted by techno-optimists who think we can engineer our way out of this problem,” he said.
“But the US is not ready for a metre of sea level rise by 2100.
“Just look at what happened in the wake of superstorm Sandy, Katrina, in Houston, or Puerto Rico.”
The IPCC’s Special Report on the Ocean and Cryosphere in a Changing Climate is due to be published on 25 September.

Politics-As-Usual Can’t Fix The Climate Crisis. Maybe It’s Time To Try A Citizens’ Assembly

The Guardian

Extinction Rebellion is calling for the approach that ended Ireland’s abortion deadlock to be used in the UK

David Farrell
Professor David Farrell is the head of politics and international relations at University College Dublin. He was the research leader of the Irish citizens’ assembly.
The climate crisis demands an urgent, realistic and sustained response from governments around the world: such a response will inevitably require sacrifices from all of us. And there lies the rub for our systems of representative democracy.
How can politicians facing short-term constraints (particularly the need to be re-elected every few years) be expected to take the necessary decisions that require long-term and, probably, quite painful change on the part of the citizens who get to vote for them.
This is where a citizens’ assembly could help, as the experience in Ireland shows. The country’s ban on abortion was an intractable problem that generation after generation of political leaders had failed to resolve. In 2016, under intense domestic and international pressure, the Irish government established a citizens’ assembly and tasked it with coming up with recommendations. It met over the course of five long weekends spread across five months.
The 99 citizen members heard from expert witnesses, advocates and women who had been affected by Ireland’s abortion ban. In carefully facilitated roundtable discussions the members deliberated on the subject, producing a series of recommendations that were then sent back to parliament. A special all-party committee of parliament spent a number of months debating the recommendations. The result of this was the decision to have a referendum, which passed by a two-thirds majority in the summer of 2018.
In Britain, the Extinction Rebellion group believes that a citizens’ assembly could play a similarly important role in addressing the climate emergency. At the heart of a citizens’ assembly is random selection: in much the same way as for jury duty, regular citizens are selected at random. They have not run for office; they are not there to represent special interests. The citizen members are there to represent themselves, and thereby the greater population, of which they are a representative sample.
This is bringing “disorganised society” into the room – giving regular citizens a voice in helping to drive debates on important public policy.
These citizens, in turn, are put in the special position of informing and educating the political classes – helping our political leaders to work through the complexities of a difficult issue; informing them of aspects they might not have considered before; giving them a sense of where citizens might be prepared to go; even providing some degree of political cover.
What is laudable about the Extinction Rebellion agenda is that the activists are not pushing for particular policy decisions on the climate emergency: they are merely asking that their government agrees to establish a citizens’ assembly and give it the task of bringing forward proposals.
There are certain things that need to happen for this to work properly. The citizens’ assembly should be established by government, not parliament (because it is the government that ultimately calls the shots), but it should report back to parliament so that all political parties are given the opportunity to debate its recommendations.
The agenda should be defined carefully. An ideal way to ensure this would be to allow the assembly itself to clarify it owns terms, guided by the experts advising it.
It is critically important that the assembly’s recommendations are dealt with respectfully: this does not mean that they are necessarily all accepted, but they should not be ignored. The Irish model of having an all-party committee debate the report would be worth emulating.
Although government sponsors it, the assembly should be run independently of government (with methods such as tendering out the task to an agency with appropriate expertise). And the process should be run openly and transparently with all documents going online, live streaming of expert presentations, and full details of the key names involved in running and advising the process. Everything possible should be done to ensure that the process is seen as objective and above board.

And the process needs time. The climate emergency cannot be dealt with adequately in a few weekends. The citizens’ assembly needs time and space to allow the members to develop sufficient expertise on the topic to be able to deliberate in a suitably informed way.
One might be forgiven for thinking that the recent announcement by the select committees of the House of Commons that they will establish a citizens’ assembly on climate change this autumn is a sign that the political establishment has listened. But actually this is not the case: that is parliament acting – not government. The agenda has been tightly defined (focused on existing 2050 targets, which many now feel are not enough). The scope is also unrealistic (only two weekends of meetings, expertise provided solely by civil servants). There is a danger that this process will be tokenistic, inadequate, and provide parliament with the cover that the “climate crisis” box has been ticked.
This climate emergency requires a courageous response from our political leaders.
This is a real test for our system of representative democracy, built on the notion that our parliamentarian ne’er-do-wells are available for a good kicking every few years. Climate breakdown presents a real conundrum because it requires a long-term solution, one that goes beyond an election cycle.
A citizens’ assembly – given sufficient time, resources and expert assistance – offers one means to solve the problem of taking difficult, long-term decisions in a political system governed by short-term rules.

Greta Thunberg, Climate Change Activist, Sails Into New York City

BBC


Greta Thunberg sails into New York City

Teenage environmental activist Greta Thunberg has arrived in New York after a 15-day, 3,000-mile (4,800km) voyage across the Atlantic.
She will be participating in UN climate summits in New York City and Chile.
The 16-year-old Swede sailed from Plymouth in the UK on a zero-emissions yacht in order to minimise the carbon footprint of her travel.
"Our war on nature must end," she told reporters shortly after arriving on Wednesday.
"I want to thank everyone... who is involved in this climate fight, because this is a fight across borders, across continents," she said.
When asked about the fires that have ravaged the Amazon rainforest in recent weeks, she said they were a "clear sign we need to stop destroying nature
Ms Thunberg was expected to arrive sooner, but rough seas slowed her progress. She has been documenting the voyage on social media.
As she departed the UK two weeks ago, she told the BBC that travelling by boat sends a signal that "the climate change crisis is a real thing".
When asked if she could make US President Donald Trump listen she answered with a simple "no".
"I'm not that special. I can't convince everyone," she said. "I'm just going to do what I want to do and what will have most impact."
On arrival in New York she had another message for Mr Trump: "My message for him is listen to the science and he obviously doesn't do that."
She will be present at the UN climate summit on 23 September and the COP25 climate conference in Chile in December.

The Swedish teen behind the climate strikes

The teenager has made headlines for her "school strikes" which have inspired a worldwide climate change protest movement.
Her first "strike for climate" took place outside the Swedish parliament in August last year.
Ms Thunberg travelled on the Malizia II, a high-speed, 60ft (18m) racing yacht with underwater turbines and no carbon emissions.
She made the journey with her father Svante, captain Boris Herrmann, Monaco royal family member Pierre Casiraghi and a Swedish documentary maker, Nathan Grossman.

Her boat had no shower or toilet, according to Reuters, and the sailing party ate freeze-dried food.
The teenager was nominated for a Nobel Peace Prize earlier this year.
Ms Thunberg has been diagnosed with Asperger's, a form of autism, which she told the BBC allowed her to "see things from outside the box".
"If I would've been like everyone else, I wouldn't have started this school strike for instance," she said.

Wind And Solar Set New Generation Records Across Australia Grid In July

RenewEconomy | 


Wind generation set new records across Australia’s main grid in July, helping the combined output of “new renewables” – that is wind and solar – to also reach a new peak for the month.
The milestone was noted in The Australia Institute’s monthly National Energy Emissions Audit, published on Tuesday, which shows that average monthly wind generation set new record levels in both Victoria and NSW in July.


And across the entire National Electricity Market, wind power set a new peak output benchmark of 4,586MW at 9pm on July 14, when it was supplying 18 per cent of total generation.


The record wind levels also helped “new” renewable generation – that is, excluding the “traditional” renewables of hydro and biomass – achieve a record monthly share of NEM generation (Figure 8), even in a month that is typically poor for solar.


“(A) rise in renewables can be seen across Australia,” said Hugh Saddler, the author of the TAI report that also highlights the world-leading example that is being set by South Australia, on how to move ‘beyond baseload.’
“Our Audit shows that wind supplied a record 18 per cent of total NEM generation on 14 July, the equivalent output of over two Liddell power stations,” Saddler said, referring to the ageing coal clunker that is now due exit the market in April 2023, after intense pressure from the federal Coalition to keep it open passed its use-by date.
“Australia can quickly and affordably transition to renewables and storage, as demonstrated by South Australia, but investigations into so-called baseload energy, like nuclear, are a complete distraction by government.”

BCA Rejects Climate Change Campaign

AFRJohn Kehoe

The Business Council of Australia has written to institutional investors to hit back against claims by climate change activist groups that the corporate lobby group is blocking changes to tackle global warming.
In a letter to institutional investors sent this week, BCA chief executive Jennifer Westacott and president Grant King said they wanted to clarify that the group “supports strong action on climate change”.
Grant King and Jennifer Westacott have written to institutional investors to clarify the group's position on climate change. Wolter Peeters
Activist groups such as the Australasian Centre of Corporate Responsibility (ACCR) and Australian Conservation Foundation, both registered charities, have been “naming and shaming" firms including AGL, BHP, National Australia Bank, Origin Energy, Qantas, Rio Tinto, Santos, Westpac and Woodside Petroleum over their membership of industry groups and their level of support for climate change action.
Energy companies have also been slammed for using coal-fired power stations.
The ACCR has filed resolutions at shareholding meetings and pressed institutional investors such as superannuation funds to demand the companies quit or review their memberships of the Business Council of Australia, Minerals Council of Australia and Australian Petroleum Production and Exploration Association.
Member companies, particularly consumer-facing businesses which have minimal emissions and are committed to strong action on climate change, such as Telstra and the big banks, have been unnerved by the campaigns.
Ms Westacott and Mr King said in the letter to big investors the BCA is being targeted "because we have sought to be transparent about the costs and trade-offs required in the necessary transition to a low-emissions economy."
“If we are to finally achieve a durable climate policy, we must have an open and honest debate about the impact of the changes required to become a lower emissions economy,” they wrote.
“We support strong action on climate change combined with solutions to curtail the rapid growth in energy costs and measures to improve the reliability of electricity supply in Australia.
“This is a longstanding policy position and represents a pragmatic approach to a global issue.
“The BCA and its members believe this transition should take place at the lowest possible cost to ensure that Australia’s standard-of-living is not put at risk.
"Australian businesses and households must have access to energy that remains reliable, secure and affordable as the sector progressively decarbonises.”
The BCA has long supported a market-based price signal to limit carbon emissions and was a strong backer of the Turnbull government’s proposed National Energy Guarantee for the electricity sector, which was derailed last year by Coalition conservatives.
It backs Australia’s 26-28 per cent emissions reduction target by 2030 under the Paris international climate accord.
Industry representative groups are increasingly under pressure over climate change, as their disparate range of members clash over the level of proposed emissions cuts, coal, renewable energy and other energy policies.
BHP in 2017 delivered an ultimatum to the Minerals Council to stop lobbying governments to fund new coal-fired power stations or risk losing the company as a member.
BHP played a pivotal role in ousting Brendan Pearson as Minerals Council chief executive over his advocacy for "clean coal" after BHP revealed it had "material differences" of opinion with the MCA, the World Coal Association and the US Chamber of Commerce.
Mr Pearson is now a senior trade adviser to Prime Minister Scott Morrison.
The Australian Financial Review reported in April that Rio Tinto had threatened to walk away from the Minerals Council over climate change, though today it remains a member of the council.

Climate Change Is Likely To Devastate The Global Food Supply. But There's Still Reason To Be Hopeful

Amanda Little
Amanda Little is a professor of journalism and science writing at Vanderbilt University and the author of The Fate of Food: What We’ll Eat in A Bigger, Hotter, Smarter World.
The most troubling paradox of the 21st century may be that human population is expected to climb to 9.7 billion by midcentury — yet the global food supply is predicted to plummet.
The Special Report on Climate Change and Land released earlier this month by the United Nations’ International Panel on Climate Change, penned by experts in more than 50 countries, details in stark terms “the risk to millions of people from climate extremes, desertification, land degradation and food and livelihood insecurity.” Another recent IPCC report predicted a 2 to 6 percent decline in global crop yields every decade going forward — that’s potentially millions of acres phasing out annually — due to drought, heat, flooding, superstorms, weather volatility, shifting seasons, insect infestations and other symptoms of a warming planet. According to Jerry Hatfield, the director of the U.S. Department of Agriculture’s National Laboratory for Agriculture and the Environment, the single biggest threat of climate change is the collapse of food systems: “Other threats — flooding, storms, forest fires — may be more sudden and severe in certain regions, but disruptions in food supply will affect virtually everyone.”
For most of us, this still feels like an abstract problem. The industrialized world on the whole is enjoying a more abundant, diverse and accessible food supply than ever before in human history. The supermarket that’s located a few hundred feet from my house is open 19 hours a day, seven days a week, and stocks more than 50,000 distinct food items deriving from countries as far-flung as Zimbabwe. Many of us are more worried about too many food options, not too few of them.
But disruptions in supply are already evident almost everywhere food is grown.
Last month, the heat wave that swept Europe scorched old vineyards and new cornfields alike. When Bordeaux reached a record 106 degrees Fahrenheit, France’s Minister of Agriculture said the country’s coveted wine production would decline up to 13 percent in 2019. The soy and corn farmers in the American Midwest, meanwhile, faced a very different problem: sodden fields from unusually heavy spring rains were too wet to plant, resulting in billions of dollars of lost crops. Climatic pressures in recent years have also damaged or destroyed millions of acres of olive groves in Italy, citrus and peach orchards in Florida and Georgia, apple and cherry orchards in Wisconsin and Michigan, avocado farms in Mexico, coffee and cacao farms in dozens of equatorial nations. Water-intensive dairy and livestock operations are suffering the world over.
While threats to food production are varied and region-specific, a single story connects them: Climate change is becoming something we can taste. This is now a kitchen-table issue, literally and otherwise.Climate change also intensifies the existing problems in industrial food production, many of which are (in an ironic twist) themselves root causes of climate change.
Food waste, for example: more than a third of all food grown globally rots on the field or in transit or is thrown out. Rampant soil degradation has lead to the overuse of synthetic fertilizers that, in turn, evaporate into the air to form nitrous oxide, a potent greenhouse gas. Pesticides have been causing mass die-offs of bees that play Oscar-caliber supporting roles as pollinators in food production; now climate change is making life even harder for these beneficial insects.
What, we must wonder, lies ahead? Will future historians look back on our current agricultural moment and see it as Dickens did Europe in the late eighteenth century—an age of belief and incredulity when “we had everything before us, we had nothing before us”?
We have good reason to believe we’re headed toward nothing. By the middle of this century, a 2014 IPCC report reads, the world may reach “a threshold of global warming beyond which current agricultural practices can no longer support large human civilizations.” But that fate hinges on a key assumption — that current agricultural practices won’t change. And if my research has taught me anything, it’s that farmers, scientists, activists and engineers the world over are radically rethinking food production.
I spent the past five years exploring the lands, minds and machines, working on the future of food, traveling from small apple orchards in Wisconsin and tiny cornfields in Kenya to massive Norwegian fish farms and computerized foodscapes in Shanghai. I investigated new and old ideas, from robotics, CRISPR, alternative meats and vertical farms to edible insects, permaculture, fertilizer management and ancient plants. I learned through research in more than a dozen countries and as many states that human innovation, which marries new and old approaches to food production and land management, can build climate resilience and redefine sustainable food on a grand scale.

Amazon Fires: Satellite Images Show What’s Happening In Brazil

Grist

High-resolution images from satellite company Planet are revealing glimpses of some of the fires currently devastating the Amazon rainforest.
While many of the images currently being shared on social media and by news outlets are from past fires — some from as long as 15 years ago — satellites can provide a near real-time view of what’s unfolding in the Amazon. With near-daily overflights and high-resolution imagery, Planet’s constellation of satellites is providing a clear look at some of the fires now burning in the Brazilian Amazon.
Beyond dramatic snapshots, those images also provide data that can be mined for critical insights into what’s happening in the Amazon on a basin-wide scale, according to Greg Asner, the director of the Center for Global Discovery and Conservation Science at Arizona State University, whose team is using Planet’s data to assess the impact of the fires on carbon emissions.
“Planet data provides unprecedented detail in mapping forest change down to individual trees which allows us to assess the damage from these kinds of large scale disturbances,” Asner said. “Our Planet Incubator Program is currently tracking forest carbon emissions all over the world — including the Amazon — using Planet Dove and SkySat imagery.”
“If you took all of the carbon stored in every tropical forest on Earth and burned it up, you would emit about five times the carbon dioxide into the atmosphere that is already there,” he said. “The Amazon rainforest represents about half of this forest carbon, to give you an idea of how serious this current situation is and the kind of impact it will have on climate change.”

Planet wouldn’t comment what the images show specifically, but there are strong indications from other sources that many fires are burning near areas of recent deforestation. Analysis released this week by IPAM Amazônia, a Brazilian research group, shows that the 10 Amazonian municipalities that had the most fire outbreaks this year were also the ones that had the highest deforestation rates.“These municipalities are responsible for 37 percent of the hotbeds in 2019 and 43 percent of recorded deforestation through July,” states the IPAM report. “This concentration of forest fires in newly deforested areas with mild drought represents a strong indication of the intentional character of the fires.”
In other words, fires are being set to clear lands for agriculture, most likely cattle pasture, which accounts for 70 to 80 percent of forest conversion in the Brazilian Amazon. Typically a landowner will cut and harvest valuable timber trees before slashing and burning the remaining trees. The resulting ash provides a temporary source of nutrients for pasture grass, but the soil degrades quickly without careful management.
While old-growth Amazon rainforest doesn’t typically burn naturally outside droughts and El Niño years, fires set intentionally in degraded forests and agricultural lands can burn hot enough to spread deep into otherwise untouched forests. That seems to be what’s happening this year, which, as IPAM noted, isn’t especially dry.
However that may soon change — for the worse.
With climate models forecasting a much hotter Amazon due to rising carbon dioxide concentrations in the atmosphere, a growing chorus of scientists are warning that the combination of continued deforestation and climate change could tip the wet Amazon rainforest toward a much drier, savanna-like ecosystem. Since the trees of the Amazon generate much of region’s precipitation, such a shift could be devastating for the region’s water supplies. The agricultural heartland of South America is predicted to be particularly hard hit by water scarcity, but diminished rainfall would also affect cities’ electricity supplies, which are disproportionately dependent on hydropower. Drier conditions would exacerbate fire and air pollution risk as well.

Fires and deforestation up in 2019
Deforestation in the Brazilian Amazon has been trending upward since bottoming out in 2012 at 4,571 square kilometers (1,765 square miles), but the issue didn’t get a lot of public attention until this week, when the skies of São Paulo, one the world’s largest cities, were blackened midday by smoke from the fires. The shocking descent into darkness prompted an outpouring of concern across social media, with the #PrayforAmazonas hashtag garnering more than 300,000 tweets in two days.
But while the fires in the Amazon have indeed increased significantly over last year, they aren’t off the charts relative to the past 20 years.

The difference this year is that weather conditions led the smoke from the fires to blanket densely populated urban areas. A similar phenomenon is seen in Southeast Asia: Indonesia’s peat fires get the most attention when winds blow the resulting haze over Singapore, the regional financial hub, as was the case in 2015.
However, to environmentalists worried about the anti-environment rhetoric from President Jair Bolsonaro, the Armageddon-like conditions in São Paulo and sharp rise in deforestation seem be playing out like a worst-case scenario for the Amazon.
According to the country’s national space research institute, INPE, forest loss in the world’s largest rainforest is already pacing 57 percent ahead of last year. And the region is only halfway through the peak deforestation season that runs from May to October. Data from Imazon, a Brazilian NGO that independently tracks deforestation in the Amazon, is expected to confirm the trend when it releases the latest numbers next week.
Stung by criticism over rising deforestation, Bolsonaro has asserted INPE is manipulating deforestation data and fired the agency’s director. INPE has not released any deforestation updates since the firing. Bolsonaro also claimed, without evidence, that NGOs are responsible for starting the fires as a fundraising strategy, although he backtracked on those remarks today.
Bolsonaro, however, hasn’t been able to effectively refute the satellite data coming from places like Planet and NASA. Scientists and civil society groups are now poring over that data to look for links between Bolsonaro’s policies — including weakened environmental laws, relaxed law enforcement, and amnesty for illegal deforesters — and what’s happening on the ground in the Amazon.
“While links between Brazilian government policy and these wildfires are unknown, the unprecedented data coming from Planet will allow us to help evaluate the extent to which their policies need to be reexamined,” Asner said.

How Should We Talk About What’s Happening To Our Planet?

Washington PostDan Zak

Barry Falls for The Washington Post)
In the middle of a winter’s night in 2017, Frank Luntz’s cellphone alerted him to a nearby wildfire. The longtime analyst of public opinion opened his bedroom curtains and saw, less than a mile away, flames chewing the dark sky over Los Angeles.
Luntz — who specializes in how the public reacts to words — saw scary evidence of a threat that he once tried to neutralize with language.
In 2001, he’d written a memo of environmental talking points for Republican politicians and instructed them to scrub their vocabulary of “global warming,” because it had “catastrophic connotations,” and rely on another term: “climate change,” which suggested “a more controllable and less emotional challenge.”
Last month, with a revised script, Luntz appeared before the Senate Democrats’ Special Committee on the Climate Crisis.
“I’m here before you to say that I was wrong in 2001,” Luntz said. Nearby was a colorful chart of vocabulary, developed since his polling in 2009 showed bipartisan support for climate legislation. He went on: “I’ve changed. And I will help you with messaging, if you wish to have it.”
Don’t talk about threats, he told the senators. Talk about consequences.
Don’t talk about new jobs created by green energy. Talk about new careers.
And sustainability?
“Stop,” Luntz said. “Sustainability is about the status quo.”
Even the committee’s name had a troublesome word in it: “crisis.” It’s flabby from overuse, Luntz thought. If everything is a crisis, then nothing is.
From a word standpoint, that’s true. And sometimes it feels true in the real world. The phone in your hand has become a police scanner of unfolding crises. The Kashmir crisis, the Hong Kong crisis, the border crisis, the trade crisis, the measles crisis. The crisis of mass shootings, of the national debt, of Puerto Rico, Brexit, the Amazon.
And, yes, the climate crisis, formerly climate change — somehow the least tangible but most alarming of the crises, which makes it trickier to talk about.
Those who are talking about it have ratcheted up their rhetoric. In May, the Swedish activist Greta Thunberg ditched “climate change” for “climate breakdown” or “climate emergency.” The Guardian now uses “climate catastrophe” in its articles.
A resistance movement born in Europe last year named itself Extinction Rebellion, partly to normalize the notion of aggressive action in a life-or-death situation.
Luntz wants defter language. “The strongest advocates for a particular issue are often the worst communicators,” he says later by phone, because “they forget that the people they need to convince are not themselves or their friends.”
The climate problem is not just scientific. It’s linguistic. If we can agree how to talk and write about an issue that affects us all, maybe we can understand and fix it together.
But words can be clumsy tools. They can be too dull to puncture ignorance, or so sharp that people flinch and turn away.
Is “change” appropriately neutral, or unjustly neutered? Is an “emergency” still an “emergency” after months or years? Does “catastrophe” motivate people, or make them hide under the bed? How long before words such as “breakdown” and “extinction” lose their bite?
And if we keep returning to the dictionary for new words to replace them, will there eventually be any left?

The second volume of the fourth National Climate Assessment is 1,515 pages long. The word "likely" appears 867 times, sometimes after "very" or "extremely." Last spring, as they distilled data into text, the scientists who wrote the report spent long hours debating the usage of "likely."
Without significant action to curb climate change, they wrote in the final chapter, “it is very likely that some physical and ecological impacts will be irreversible for thousands of years, while others will be permanent.”
When translated to conversational English, “very likely” becomes “this is something really bad and totally crazy and wild,” says one author of the report, who spoke on the condition of anonymity to discuss internal deliberations.
“Why don’t we use plain language and say, ‘Yes, this is crazy and, yes, you should be freaking out’? Because that’s not fair. That’s not the role of the National Climate Assessment,” the author says. “But then we sort of fail as a community in actually getting people to understand the severity of it.”
The science community is supposed to interpret for the rest of us, but its dialect does not always pack rhetorical oomph. “I didn’t realize that pointing to a climate graph I think is the Rosetta stone — people don’t see it the way I see it,” says Brenda Ekwurzel, director of climate science for the Union of Concerned Scientists. “We as humans don’t experience an exponential curve viscerally, in our gut.”
In the industrial age, environmentalist writers have tried to access the brain via the gut. “Thank God men cannot fly, and lay waste the sky as well as the earth,” Henry David Thoreau wrote in the 19th century.
In the 1960s, Rachel Carson envisioned an ecosystem silenced by chemicals: “Everywhere was a shadow of death.” In the 1980s, as global warming was first debated widely, Bill McKibben pondered “the end of nature” itself.
But “there’s a point at which words like ‘climate change’ become part of your mental furniture,” McKibben says in an interview. “Like ‘urban violence’ — things that are horrible problems but you just repeat the thing so often that people’s minds kind of skip over them.”
Terms lose their power as they get used over many years, says Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, and “come to accrete their own set of connotations.”
Such as: elitist, liberal, socialist. When thousands of pages of analysis become a two-word slogan, it passes from science to politics. Facts become less important than feelings. For some people, “climate change” is a wedge word synonymous with “hoax” and calls to mind former vice president Al Gore. For others, it summons the specter of ExxonMobil and is a rallying cry for restructuring the global economy.
“The facts do not speak for themselves,” says Richard Buttny, a professor in the department of communication and rhetorical studies at Syracuse University. “People make decisions based on values.”
And therein lies an opportunity, according to Kim Cobb, professor of earth and atmospheric sciences at Georgia Tech. Scientists observe and publish findings for the public, Cobb says, but then often fail to “recognize the emotional toll this takes on the recipient and the challenge to their core values.”
Cobb refrains from using words such as “crisis” and “emergency” on Twitter, where the character limit discourages context and nuance.
Instead, she elevates language about solutions, and about the emotions triggered by the science, in the hopes of widening the circle of understanding.
“We’re way behind creating these communities for shared values and shared goals,” Cobb says. “And from that comes shared language.”

We are gradually building that language to talk about where we are, where we're going and about the emotions that accompany that knowledge.
The Germans have a word for feeling guilty about flying on airplanes: “flugscham,” or “flight shame.”
The biologist Edward O. Wilson has a word for a future epoch following a profound loss of species: “the Eremocine,” or “the Age of Loneliness.”
Karla Brollier, founder of the Climate Justice Initiative, is listening to her fellow indigenous Alaskans as their language evolves to include loss and adaptation, without relying on words such as “climate refugee” that connote victimhood.
Jennifer Atkinson’s students at the University of Washington at Bothell have used “blissonance” to describe the feeling of enjoying a record-hot day in winter — while recognizing that climate change might have something to do with it.
“Solastalgia,” coined by environmental philosopher Glenn Albrecht, means distress over change in one’s home environment. Atkinson phrases it as a homesickness without ever having left home.
Her students “describe how the sound of frogs has slowly disappeared over time — these changes that destabilize connections to personal memories,” says Atkinson, a senior lecturer at Bothell. “Unlike with personal bereavement, we don’t have a vocabulary for the grief people have for the loss of the natural world.”
Her course is called “Environmental Anxiety and Climate Grief.” One of the goals is to search for ways of communicating outside the bounds of science and its “value-neutral” vocabulary — all those likelys and somewhat likelys.
“We’re moving into an age of great earnestness, because we’re trying to figure out, ‘How do we show up for each other?’ ” says Sarah Myhre, a climate and ocean scientist who has studied social and ecological decision-making. “And the language that’s being used in my spaces is all about heart-centered work.”
Whereas Frank Luntz once tried to strip the climate problem of emotional resonance, Atkinson, Myhre and others are acknowledging and amplifying it. Whereas science has traditionally been guided by dispassionate, male-centric authority, women are rewording climate conversations to honor the collective, connective nature of the problem.
And how we talk about the environment affects how we think about it. In the colonial and industrial ages, Myhre says, our language reflected an idea of the natural world as an inventory of useful commodities — separate from, and subservient to, humanity.
Trees became timber.
Animals became livestock.
Oil and coal became fuels.
And thus a cultural problem has given birth to an environmental one, says Daniel Wildcat, a professor at Haskell Indian Nations University in Kansas.
“Think of how our worldview changes if we shift from thinking that we live in a world full of resources,” he says, “to a world where we live among relatives.”

In June, the White House slashed its red pen through certain labels in written congressional testimony from a State Department analyst.
When the analyst used "possibly catastrophic" to describe the future impacts of climate change, a member of the National Security Council typed a note in the margin: "not a science-based assessment but advocacy for the climate-alarm establishment."
The analyst listed “tipping point processes” on a page that was entirely crossed out. A note in the margin: “ ‘Tipping points’ is a propaganda slogan designed to frighten the scientifically illiterate.”
Some activists believe fright is appropriate, and they’re eager to use keener language than “tipping points” to do it.
“We’ve been told for years: ‘Don’t scare people, people don’t want to know the bad news’ — and all that’s meant is nothing’s changed,” says Charlie Waterhouse, founder of the company behind Extinction Rebellion’s branding. “We know that we have to up the ante, and we have to have a more extreme position because that opens that crack that lets other people follow.”
The word “extinction” is a blunt instrument that whacks at complacency.
The word “rebellion” invites enlistees and subverts established power structures.
But this “constant inflation” in terminology hampers rational discussion, says the Danish author Bjorn Lomborg, whose skeptical writings on the economics of climate action have riled scientists and activists.
Words such as “catastrophe” and “extinction” imply that we should either cower and do nothing, or overreact and do everything, says Lomborg, who is president of the Copenhagen Consensus Center.
“The conversation we should have is: How do we make smart policies that cost less than the damage they reduce?” Lomborg writes in an email. “Climate policy shouldn’t be done with labels but with careful analysis.”
We don’t need labels as much as we used to, back when the effects of climate change were forecast instead of seen and felt.
“In a certain sense, words are no longer as necessary as they once were,” says McKibben, author of “The End of Nature.” “Twenty or 30 years ago we were describing things that hadn’t happened yet, so you couldn’t take a picture of them. Now every single day you can take 1,000 pictures around the world of the trauma of climate change.”
Nearly two decades after Frank Luntz recommended it, “climate change” may still be the closest thing to a shared language that Americans have for describing what’s happening to the planet. But we diverge from there.
Scientists speak about consequences. Activists speak about crises and catastrophes. Politicians speak about doubt and propaganda.
And if you’re paying attention, you’ll hear nature speaking loudly for itself.

What Does '12 Years To Act On Climate Change' (Now 11 Years) Really Mean?

InsideClimate News - Bob Berwyn

It doesn't mean the world can wait until 2030 to cut greenhouse gas emissions, or that chaos will erupt in 2030. Here's what the science shows.

We've been hearing variations of the phrase "the world only has 12 years to deal with climate change" a lot lately.
Sen. Bernie Sanders put a version of it front and center of his presidential campaign last week, saying we now have "less than 11 years left to transform our energy system away from fossil fuels to energy efficiency and sustainable energy, if we are going to leave this planet healthy and habitable."
But where does the idea of having 11 or 12 years come from, and what does it actually mean? 
The number began drawing attention in 2018, when the United Nations' Intergovernmental Panel on Climate Change released a report describing what it would take to keep global temperatures from rising more than 1.5 degrees Celsius, a goal of the Paris climate agreement. The report explained that countries would have to cut their anthropogenic carbon dioxide emissions, such as from power plants and vehicles, to net zero by around 2050. To reach that goal, it said, CO2 emissions would have to start dropping "well before 2030" and be on a path to fall by about 45 percent by around 2030 (12 years away at that time).
Mid-century is actually the more significant target date in the report, but acting now is crucial to being able to meet that goal, said Duke University climate researcher Drew Shindell, a lead author on the mitigation chapter of the IPCC report.
"We need to get the world on a path to net zero CO2 emissions by mid-century," Shindell said. "That's a huge transformation, so that if we don't make a good start on it during the 2020s, we won't be able to get there at a reasonable cost."

How Do Scientists Know?
Basics physics and climate science allow scientists to calculate how much CO2 it takes to raise the global temperature—and how much CO2 can still be emitted before global warming exceeds 1.5°C (2.7°F) compared to pre-industrial times.
Scientists worked backward from that basic knowledge to come up with timelines for what would have to happen to stay under 1.5°C warming, said Scott Denning, who studies the warming atmosphere at Colorado State University.
"They figured out how much extra heat we can stand. They calculated how much CO2 would produce that much heat, then how much total fuel would produce that much CO2. Then they considered 'glide paths' for getting emissions to zero before we burn too much carbon to avoid catastrophe," he said.
"All this work gets summarized as 'in order to avoid really bad outcomes, we have to be on a realistic glide path toward a carbon-free global economy by 2030.' And that gets translated to something like 'emissions have to fall by half in a decade,' and that gets oversimplified to '12 years left.'
"There's certainly a grain of truth in the phrase, but it's so oversimplified that it leads to comically bad misconceptions about how to get there, conjuring up ridiculous cartoon imagery suggesting we just go on with life normally for the next 11 years and then the world ends," Denning said.
That's not what the IPCC writers envisioned, he said.
The science on the 2030 date is clear, said Michael Mann, a climate scientist at Pennsylvania State University. The controversy stems from people mischaracterizing the carbon reduction timeline as a threshold for climate disaster. He noted that people promoting climate science denial and delay have also latched on to the phrase "to intentionally try to caricature the concern about climate change."

What Would Success Look Like?
It would be helpful if people looked at the 2030 target in terms of what success looks like rather than what failure means, Denning said.
"Solving the problem by 2030, 2040 or 2050 requires a new global energy infrastructure, which is arguably easier and less expensive than past infrastructure shifts like indoor plumbing, rural electrification, the automobile and paved roads, telecommunications, computers, mobile phones or the internet.
"All of these past changes cost tens of trillions of dollars, adjusted for inflation. All of them were hugely disruptive. All of them took a decade or more, completely changed the industrial and economic and social landscape, and created bursts of growth and productivity and jobs. And arguably, all of them made life better for huge numbers of people."
This time, the shift is from heavy reliance on carbon-emitting fossil fuels to carbon-free energy sources, like wind power. And even with a speedy energy transition, the IPCC says keeping temperatures from warming more than 1.5°C will also likely require removing CO2 from the atmosphere on a large scale.
Missing the target doesn't imply the onset of cataclysmic climate change in 2030, Denning said.
"Things just keep getting worse and worse until we stop making them worse, and then they never get better," he said. "But no matter what, the world has to move on from fossil fuels just as we moved on from tallow candles and outhouses and land lines."

What Would Exceeding 1.5°C Warming Mean?
The IPCC report described how increasing greenhouse gas emissions will result in more dangerous and costly disruptions to global societies and ecosystems, including longer, hotter heat waves and more frequent crop-killing droughts.
Mountain glaciers will melt faster as the planet warms, creating new risks for settlements in the valleys below. The meltdown of polar ice sheets is also projected to accelerate, intensifying flooding and speeding up sea level rise to a rate that will be hard to adapt to. More Arctic permafrost will thaw, releasing more greenhouse gases to the atmosphere.
Despite the rising risks, it's important to understand that, "in the physical climate system, there are no scientists claiming that there is a magical threshold that we breach or don't breach that determines whether we have a habitable climate system," said Daniel Swain, a climate scientist at UCLA and the National Center for Atmospheric Research's Center for Climate and Weather Extremes.
The 2030 target is useful because it shows how the "next decade is incredibly consequential for what we do." Swain said. "But I think the emphasis that's being placed on this specific 12-year window as a differentiator between existential crisis or not is problematic.
"First of all, it negates some of the risks that already exist and that will continue to build no matter what. And it also potentially suggests that anything short of complete victory in the next 12 years is pointless, which is exactly the opposite of the truth. At any point along the spectrum, more progress is always going to be better than less progress, less warming is always going to be better than more warming."

Have We Passed Tipping Points Already?
In some ways, the "12 years" narrative may set up a deadline that's too lenient, because some key part of the climate system may already be at or past tipping points, Swain said.
It creates the false illusion that there is some sort of guardrail moving forward, that if we just get in under the deadline we'll be OK, he said. But "twelve years from now, it could be too late for some of these things, like the ice sheets."
Research in the past few years reinforces the idea that some climate tipping points have already been breached. Studies show some parts of the Greenland Ice Sheet are unlikely to recover, and parts of the West Antarctic Ice Sheet may also be at or very near a tipping point to rapid disintegration.
A study published in June suggested that the rate of permafrost thawing is progressing much faster than climate models projected. And scientists studying the link between global warming and European heat waves said those recent extremes are also outside the scope of what they expected at current levels of warming.
The world will still exist if we breach 1.5°C and 2°C, but "the climate impacts and risks will be higher and the temperature will be higher," said Glen Peters, research director at the CICERO climate research center in Oslo. That all seems to be sinking in to public awareness, he said.
"But in terms of deadlines, we have already missed the deadline," he said. "We should have started mitigating decades ago, then we would have the problem solved."
