O relógio do Apocalipse / Aquecimento Global



While economic growth continues we’ll never kick our fossil fuels habit

There may be more bicycles but there will also be more planes. We’re still in denial about the scale of the threat to the planet

We’re getting there, aren’t we? We’re making the transition towards an all-electric future. We can now leave fossil fuels in the ground and thwart climate breakdown. Or so you might imagine, if you follow the technology news.

So how come oil production, for the first time in history, is about to hit 100m barrels a day? How come the oil industry expects demand to climb until the 2030s? How is it that in Germany, whose energy transition (Energiewende) was supposed to be a model for the world, protesters are being beaten up by police as they try to defend the 12,000-year-old Hambacher forest from an opencast mine extracting lignite – the dirtiest form of coal? Why have investments in Canadian tar sands – the dirtiest source of oil – doubled in a year?

The answer is, growth. There may be more electric vehicles on the world’s roads, but there are also more internal combustion engines. There be more bicycles, but there are also more planes. It doesn’t matter how many good things we do: preventing climate breakdown means ceasing to do bad things. Given that economic growth, in nations that are already rich enough to meet the needs of all, requires an increase in pointless consumption, it is hard to see how it can ever be decoupled from the assault on the living planet.

When a low-carbon industry expands within a growing economy, the money it generates stimulates high-carbon industry. Anyone who works in this field knows environmental entrepreneurs, eco-consultants and green business managers who use their earnings to pay for holidays in distant parts of the world and the flights required to get there. Electric vehicles have driven a new resource rush, particularly for lithium, that is already polluting rivers and trashing precious wild places. Clean growth is as much of an oxymoron as clean coal. But making this obvious statement in public life is treated as political suicide.

The Labour party’s new environment policy, published this week, rightly argues that “our current economic model is threatening the foundations on which human wellbeing depends”. It recognises that ecological collapse cannot be prevented through consumer choice or corporate social responsibility: the response to our greatest predicament must be determined by scientific research, and planned, coordinated and led by government. It pledges “to meet the Paris agreement goal of limiting global temperature rises to no more than 1.5C”. But, like almost everyone else, it ignores the fundamental problem. Beyond a certain point, economic growth – the force that lifted people out of poverty, and cured deprivation, squalor and disease – tips us back into those conditions. To judge by the devastation climate breakdown is wreaking, we appear already to have reached this point.

The contradiction is most obvious when the policy document discusses airports (an issue on which the party is divided). Labour guarantees that any airport expansion must adhere to its tests on climate change. But airport expansion is incompatible with its climate commitments. Even if aircraft emissions are capped at 2005 levels, by 2050 they will account for half the nation’s carbon budget if the UK is not to contribute to more than 1.5C of global warming. If airports grow, they will swallow even more of the budget.

Airport expansion is highly regressive, offending the principles of justice and equity that Labour exists to uphold. Regardless of the availability and cost of flights, they are used disproportionately by the rich, as these are the people with the business meetings in New York, the second homes in Tuscany, and the money to pay for winter holidays in the sun. Yet the impacts – noise, pollution and climate breakdown – are visited disproportionately on the poor.

I recognise that challenging our least contested ideologies – growth and consumerism – is a tough call. But in New Zealand, it is beginning to happen. Jacinda Ardern, the Labour prime minister, says: “It will no longer be good enough to say a policy is successful because it increases GDP if it also degrades the physical environment.” How this translates into policy, and whether her party will resolve its own contradictions, remains to be determined.

No politician can act without support. If we want political parties to address these issues, we too must start addressing them. We cannot rely on the media to do it for us. A report by the research group Media Matters found that total coverage of climate change across five US news networks (ABC, CBS, NBC, Fox and PBS) amounted to 260 minutes in 2017 – a little over four hours. Almost all of it was a facet of the Trump psychodrama (Will he pull out of the Paris accord? What’s he gone and done this time?) rather than the treatment of climate chaos in its own right. There was scarcely a mention of the link between climate breakdown and the multiple unnatural disasters the US suffered that year; of new findings in climate science; or of the impacts of new pipelines or coalmines. I cannot find a comparable recent study in the UK. I suspect it is a little better, but not a lot.

The worst denial is not the claim that this existential crisis isn’t happening. It is the failure to talk about it at all. Not talking about our greatest predicament, even as it starts to bite, requires a constant and determined effort. Taken as a whole (of course there are exceptions), the media are a threat to humanity. They claim to speak on our behalf, but they either speak against us or do not speak at all.

So what do we do? We talk. As the climate writer Joe Romm argued in ThinkProgress this year, a crucial factor in the remarkable shift in attitudes towards LGBT people was the determination of activists to break the silence. They overcame social embarrassment to broach issues that other people found uncomfortable. We need, Romm argues, to do the same for climate breakdown. A recent survey suggests that 65% of Americans rarely or never discuss it with friends or family, while only one in five hear people they know mention the subject at least once a month. Like the media, we subconsciously invest great psychological effort into not discussing an issue that threatens almost every aspect of our lives.

Let’s be embarrassing. Let’s break the silence, however uncomfortable it makes us and others feel. Let’s talk about the great unmentionables: not just climate breakdown, but also growth and consumerism. Let’s create the political space in which well-intentioned parties can act. Let us talk a better world into being.

A grande orgia global


Os líderes do mundo têm vindo a adiar as decisões urgentes e o relógio do Apocalipse continua o seu percurso determinante.

ANTÓNIO SÉRGIO ROSA DE CARVALHO
9 de Agosto de 2018, 6:30

O dia 1 de Julho de 2018 foi uma data histórica para o Planeta Terra. Neste dia contaram-se 200.000 aviões simultaneamente no ar. Um número culminante, nunca antes alcançado. O dia 6 de Agosto de 2018 foi a data da publicação de um artigo na revista científica PNAS, da autoria de, entre outros, Johan Rockström, director executivo do Centro de Resiliência de Estocolmo.

Este artigo avisa-nos de que a simples ideia propagada pelo Acordo de Paris (2015) de que estabilizar a temperatura nos dois graus acima do período pré-industrial será suficiente para estabilizar o efeito de estufa é irrealista e insuficiente. A situação é mais complexa, pois trata-se de uma teia de processos e de um encadeamento de fenómenos que mutuamente se influenciam, e que a partir de um certo limite podem transformar-se num efeito de dominó activo, acelerador e imparável, tornando o Planeta inabitável.

Eles são conhecidos: o degelo do Pólo Norte com o perigo do descongelamento da permafrost e a libertação do metano. A alteração da corrente do Golfo, que já está neste momento ao nível mais baixo dos últimos 1600 anos. O degelo na Gronelândia, etc..

A data limite para descarbonizar situa-se entre 2040-2050. A partir daí as reacções conjuntas e irreversíveis podem iniciar-se, num cenário capaz de ultrapassar qualquer fantasia catastrófica.

Os líderes do mundo têm vindo a adiar as mega-urgentes decisões e o relógio do Apocalipse continua o seu percurso determinante.

Neste momento em que escrevo, encontro-me em Amesterdão e a temperatura é de 34 graus. Não chove desde Maio, e as conhecidas paisagens verdes foram transformadas num amarelo expectável no Verão alentejano mas simplesmente alarmantes na Holanda. O mesmo se verifica em toda a Europa do Norte, tendo a Suécia sido confrontada com incêndios florestais.

Simultaneamente, as cidades europeias conheceram o conhecido e sempre crescente fluxo imparável de turismo, sustentado pelo “low cost” que permite e possibilita deslocações em massa, intuitivas, inconscientes e predadoras, que já transformaram as cidades europeias, antigos locais representantes de identidade cultural, em “sítios” a serem consumidos e devorados em banquetes de hedonismo e orgias globalizadoras.

A redução de uma cidade a uma plataforma monofuncional reduzindo e sacrificando tudo a uma só actividade, leia-se turismo, apresenta sintomas destruidores para o ecossistema urbano, que estão na mesma linha, embora em escalas diferentes, dos sintomas planetários.

Qual é a pegada e o preço ambiental deste modelo de “desenvolvimento”? Qual é a pegada e o preço ambiental do “low cost flying”?

O país foi dominado pelo caso Robles e pela queda dos seus pedestais das “santas” Catarina e Joana, o que levou a tsunamis de opinião e de indignação. No entanto, com Robles & Companhia ou não, com aproveitamento político ou não destes fenómenos, os verdadeiros problemas ligados à especulação imobiliária, ao aumento apocalíptico do preço da habitação, à catastrófica dependência e vassalagem do Alojamento Local “à rédea solta” e ao flagelo dos despejos, mantêm-se na sua crescente omnipresença e omnipotência erosiva e destruidora.

E a “festa” continua imparável, no seu carácter de “festa titânica”, contribuindo na sua mobilidade incontrolada para mais C02. Em última análise, em absoluto desespero, nem nos precisamos de preocupar.

Este modelo de viagens ilimitadas, e de mobilidade predadora e consumidora da autenticidade cultural e da identidade local, é ambientalmente completamente insustentável e incomportável e na sua inconsciência criminosa. O momento de paragem desta grande orgia global aproxima-se inevitavelmente, momento dramático para Portugal, que irá acordar do seu torpor e ser obrigado a reconhecer a sua dependência e os limites da aposta exclusiva num modelo auto-destruidor e alienante.

World 'nowhere near on track' to avoid warming beyond 1.5C target

Key UN report says limiting temperature rise would require enormous, immediate transformation in human activity

Avoiding a temperature increase of more than 1.5C will be ‘extraordinarily challenging’, says the report’s author.
The world’s governments are “nowhere near on track” to meet their commitment to avoid global warming of more than 1.5C above the pre-industrial period, according to an author of a key UN report that will outline the dangers of breaching this limit.

A massive, immediate transformation in the way the world’s population generates energy, uses transportation and grows food will be required to limit the global temperature rise to 1.5C and the forthcoming analysis is set to lay bare how remote this possibility is.

 “It’s extraordinarily challenging to get to the 1.5C target and we are nowhere near on track to doing that,” said Drew Shindell, a Duke University climate scientist and a co-author of the Intergovernmental Panel on Climate Change report, which will be unveiled in South Korea next month.

“While it’s technically possible, it’s extremely improbable, absent a real sea change in the way we evaluate risk. We are nowhere near that.”

In the 2015 Paris climate pact, international leaders agreed to curb the global temperature rise to 2C above the era prior to mass industrialization, with an aspiration to limit this to 1.5C. The world has already warmed by around 1C over the past century, fueling sea level rises, heatwaves, storms and the decline of vulnerable ecosystems such as coral reefs.

Shindell wouldn’t share exact details of the IPCC report, but he said that the more ambitious 1.5C goal would require a precipitous drop in greenhouse emissions triggered by a rapid phaseout of fossil fuels, particularly coal, mass deployment of solar and wind energy and the eradication of emissions from cars, trucks and airplanes.

Even then, emerging technology will be required on a global scale to capture emissions at the source and bury them in the ground or remove carbon directly from the air.

“The penetration rate of new technology historically takes a long time,” Shindell said. “It’s not simple to change these things. There aren’t good examples in history of such rapid, far reaching transitions.”

The fading prospect of keeping the global temperature rise to below 1.5C has provoked alarm among leaders of low-lying island nations that risk being inundated should the world warm beyond this point.

“Every country must increase the ambition of their existing targets,” said Hilde Heine, president of the Marshall Islands, which announced a plan to reach net zero emissions by 2050 at the UN general assembly in New York this week. “If we can do it, so can everyone else.”

The UN general assembly has again pitted the world’s countries against Donald Trump when it comes to climate change, with the US president using his keynote speech to praise “clean coal”. Trump has vowed to exit the Paris accord, a stance that Emmanuel Macron, the French president, told the UN should be met with consequences such as a refusal by countries to enter into trade deals with the US.

“It’s a lot more difficult without the US as a leader in climate change negotiations,” Ola Elvestuen, Norway’s environment minister, told the Guardian. “We have to find solutions even though the US isn’t there.”

Elvestuen said countries, including Norway, which is one of the world’s largest oil and gas producers, need to transition away from fossil fuels, embrace electric cars and halt deforestation.

He admitted these changes hadn’t happened quickly enough since the Paris deal. Last year, global greenhouse gas emissions rose slightly again after a short period of stasis.

“We are moving way too slowly,” Elvestuen said. “We have to do more of everything, faster. We need to deliver on policies at every level. Governments normally move slowly but we don’t have the time.”

“The 1.5C target is difficult, but it’s possible. The next four to 12 years are crucial ones, where we will set the path to how the world will develop in the decades ahead. The responsibility in doing this is impossible to overestimate. To reach the goals of the Paris agreement we need large structural changes.”

A difference of 0.5C in temperature may appear small but the IPCC report, which is a summary of leading climate science, is expected to warn there will be major impacts if warming reaches 2C.

“Even 1.5C is no picnic, really,” said Dr Tabea Lissner, head of adaption and vulnerability at Climate Analytics.

Lissner said a world beyond 1.5C warming meant the Arctic would be ice-free in summer, around half of land-based creatures would be severely affected and deadly heatwaves would become far more common. “0.5C makes quite a big difference,” she said.



ARGUMENT
The Paris Accord Won’t Stop Global Warming on Its Own
The world needs a new alliance of green economic powers to create a low-carbon economic zone.

BY RICHARD SAMANS | SEPTEMBER 26, 2018, 8:24 AM

The 2015 United Nations Paris climate agreement was an important political accomplishment, but confronting climate change will ultimately require an economic breakthrough.

The Paris agreement established a consensus goal for humanity: a maximum temperature increase of 2 degrees Celsius over the level prevailing before the dawn of the Industrial Revolution in the mid-1700s. It also created a universally acceptable political framework in which states make nonbinding, nationally determined contributions toward this goal, subject to periodic peer review and voluntary adjustment.

As important as this diplomatic achievement was, it represents only half the job that the international community must perform. To stabilize the planet’s warming by midcentury at levels our children and grandchildren will find manageable, the world needs a new economic framework to accelerate the propagation of low-carbon energy innovationsTo stabilize the planet’s warming by midcentury at levels our children and grandchildren will find manageable, the world needs a new economic framework to accelerate the propagation of low-carbon energy innovations that entrepreneurs are increasingly bringing to market on competitive terms.
Even with the national commitments registered under the Paris agreement, the world remains on course for a catastrophic 3 degree temperature rise rather than the 2 degree goal set in Paris.

This new phase of international climate change cooperation will require a different cast and architecture than the one that produced the Kyoto and Paris accords. Foreign and environment ministries were the key players in the creation of the U.N. Framework Convention on Climate Change’s Kyoto Protocol in 1997 and the Paris accord in 2015, with crucial input from the scientific community through assessments organized through the Intergovernmental Panel on Climate Change.

This time around, the economic ministries (finance, trade, energy, transport, infrastructure, development, and technology) will need to be engaged as well, with active input from the business and financial communities.

While the climate diplomacy of the past two decades has taken place at the multilateral level in the U.N., this new economic phase will require a more purpose-built and variable configuration. Since the speed and volume of greenhouse gas emissions reductions is what matters most, a universal, multilateral approach will be unnecessary and even counterproductive. Global emissions are concentrated in a limited number of locations and industrial sectors, so there is no need to seek unanimous agreement among the U.N.’s nearly 200 member states.

The best approach would be for a group of like-minded major economies to use their combined market power to speed the diffusion of carbon-efficient utility, industrial, and consumer goods and services by aligning their policy incentives and standards in ways that create greater economies of scale and lower transaction costs for producers.

A coalition of countries with big markets and ambitious environmental goals as well as supportive business communities could together accelerate a shift of production and consumption patternsA coalition of countries with big markets and ambitious environmental goals as well as supportive business communities could together accelerate a shift of production and consumption patterns, directly at first within their own sizable collective share of the world economy and then indirectly in other markets as these increased economies of scale drive down production costs of low-carbon goods and services and make them more affordable globally.

Examples of climate-related economic cooperation have begun to emerge over the past several years. For example, the Major Economies Forum, World Trade Organization environmental goods negotiations, Carbon Pricing Leadership Coalition, RE100, the Financial Stability Board Task Force on Climate-Related Financial Disclosures, and other initiatives have all taken important steps forward. But relative to the challenge the world faces, these are baby steps—fledgling and uncoordinated efforts that unfortunately are not yet making a major difference in production and consumption patterns where they would most affect global emissions.
