Climate Emergency Summit – David Spratt’s Science Update

David Spratt has been on the case for some time now, and he knows the science cold. So it’s well worth your time to read this brief “state of the science” summary he wrote for the amazing Australian Climate Emergency Summit that just took placein Melbourne. Do note one of the key takeaways, emphasized in the graphic here — we will hit 1.5C around 2030.

While we’re on the subject, here’s the conference declaration. It’s very much in the “emergency mobilization demands bipartisan action” camp, which doesn’t strike me as particularly realistic these days, but what do I know? I haven’t been to Australia since the fires. No way I can make meaningful short-term political judgements.

So I’m definitely not going to argue with comms expert Peter Lewis, who recently offered this in the Guardian:

“The idea of pushing for centrist, reasonable and sensible policies may chafe when the world is on the brink. It does not dispel the need to campaign hard at the margins – climate rebellions and school strikes are essential to shifting the window to make other policy change possible. But the risk is to confuse the movement with the moment. If political change is the answer and Australia can’t wait until 2022, then locating the Overton window and finding a way through it now seems the only viable way forward.”

The Overton climate window sure is open now! New polling indicates that 64% of Australians support “Setting a zero-carbon pollution target for 2030”.

Fair Shares in the Climate President Action Plan

Over 500 US groups have signed onto a comprehensive common ask: The #CLIMATEPRESIDENT Action Plan: Ten actions that the new administration (assuming of course that there is one) should take in its first ten days.

It’s a great list, and of particular interest to us because fair shares has finally made the cut. It’s last, but hey, there’s nothing wrong with being the bottom line. The short version is: “Rejoin the Paris Agreement and lead with science-based commitments that ensure that the United States, as the world’s largest cumulative historical emitter, contributes its fair share and advances climate justice.”

The text of all ten demands is worth reading in full. Here’s the text for number ten:

“Vastly increase the United States’ emissions reduction commitment (Nationally Determined Contribution) to slash U.S. greenhouse emissions below 2005 levels by at least 70% by 2030 and reduce them to near zero by 2040 — in line with what science, equity, and climate justice demand. Include deadlines to halt all oil, gas, and coal production in the U.S. commitment and ensure that future agreements set limits on fossil fuel production consistent with meeting the 1.5°C target.

The actions in this report will form the backbone of the plan to achieve this commitment. However, because these domestic reductions alone are insufficient to fulfill the U.S. fair share of global climate action, the President must leverage their full executive authority and work with Congress to appropriate funds for large-scale financial and technological support to enable poorer countries to reduce their own emissions, as well as to support crucial adaptation measures so that vulnerable communities can survive the climate disruption already underway.”

Stefan Ramsdorf has a point

Stefan Rahmstorf is a top-tier climatologist and a great explainer, so I found it notable when, in a recent post in RealClimate (How much CO2 your country can still emit, in three simple steps), he took a few baby steps into the fraught territory of global effort sharing.

His three simple steps are:

  • Pick a global temperature goal (like, say, 1.5°C)
  • Pick a global CO2 budget (which involves some thinking about uncertainty)
  • Pick a method for divided up the (very small) remaining budget between nations

I’m not writing to make a comment on Ramsdorf’s first two steps, which are explained clearly and astutely. Though I do commend his discussion of uncertainties, and I worry that he may be a bit too diligently optimistic when it cones to Earth system feedbacks .

And I do like his caution to think in terms of budgets rather than end dates, as per:

“This is why one should not attach much value to politicians setting targets like “zero emissions in 2050”. It is immediate actions for fast reductions which count, such as actually halving emissions by 2030. Many politicians either do not understand this – or they do not want to understand this, because it is so much simpler to promise things for the distant future rather than to act now. “

I’m writing rather to note Ramsdorf’s comment on effort sharing, which manages to be both naive and helpful at the same time. Naive because, once he has made the key point, that “dividing up the remaining budget” is a matter of climate justice, not one of climate science, he chooses to do this division in terms of equal rights to emit C02, which isn’t actually, in this highly stratified world of ours, very just at all.

Why this move? Because he wants to argue that “a principle of fair distribution needs to be universal and simple.” Which per-capita emissions rights certainly are, in contrast to actual justice, which would have to consider not just equality, but also capability (which means wealth) and responsibility (which means facing history).

Why then judge this oversimple analysis helpful? Because Ramsdorf’s bottom line is that “we have to reduce emissions very very fast in the developed world, no matter how you twist and turn it.” (See the comments). And because he adds that there will have to be “a longer tail of emissions from developing nations reaching zero later.”

Both of these conditions, at this late date, are going to be almost incomprehensibly difficult to satisfy. Still, there they are. And if we have to speak very very simply in order to make them understandable, there’s an argument to be made for doing so, even if it violates the prime directive: “as simple as possible, but no simpler.”

Climate Code Red – a must read scenario

This image has an empty alt attribute; its file name is image.png

The Australian analysts at Climate Code Red are absolutely indispensable, as has been obvious since the 2017 publication of What Lies Beneath. But I’d like to draw special attention to Existential climate-related security risk: A Scenario approach, which they recently published under their new name, “Breakthrough,” which is absolutely not to be confused with the US-based “Breakthrough Institute.”

Seriously, don’t miss this report. It’s mercifully short, and its reference scenario is all too likely. Which is not at all good news. And while you’re at the Breakthrough site, take a look as well at Climate Emergency: What is safe, the 1.5º target, and is the end nigh?, wherein Breakthrough’s David Spratt explains the 1.5C target to an Australian Extinction Rebellion group.

David Spratt on 1.5C

David Spratt, the Australian hawk behind Climate Code Red, and now the Australian Breakthrough Institute, is very good on the science. And on what he calls the “emergency mode.” Not that going into “emergency mode” answer all questions about what must be done, or how to do it. But set that aside for the moment. If what you want is a summary of the science in which there are no punches pulled, watch this presentation, which David gave to a Australian Extinction Rebellion crew in May of 2019

Kevin Anderson Speaks

It’s two years now since Paris, and time for another dose of Kevin Anderson, straight-shooter extraordinaire.  You can get it by watching this talk, given at Anderson’s home base at  the University of Manchester.  The talk begins at time-code 11:00 and runs until about 42:20.   There’s a lot more to say, but Anderson fits a lot into those 31 minutes.  My only quibble is with his explanation of why the political elites behind the Paris Agreement were so eager to celebrate it, which I find to be painfully thin.   But the mainline of talk is great, as far as it goes, and that’s pretty far, actually.  Here’s a sample slide:

Fairly sharing 1.5: National fair shares of a 1.5 °C-compliant global mitigation effort

With the publication of Fairly sharing 1.5: national fair shares of a 1.5 °C-compliant global mitigation effort in the journal International Environmental Agreements: Politics, Law and Economics, we finally have a peer reviewed overview of our effort sharing framework.  It’s part of the special issue on Achieving 1.5 °C and Climate Justice

Sorry, but some of the papers are behind a paywall.  But some of them aren’t, and you can read our paper here.

“The problem of fairly distributing the global mitigation effort is particularly important for the 1.5°C temperature limitation objective, due to its rapidly depleting global carbon budget. Here, we present methodology and results of the first study examining national mitigation pledges presented at the 2015 Paris climate summit, relative to equity benchmarks and 1.5 °C-compliant global mitigation.

Uniquely, pertinent ethical choices were made via deliberative processes of civil society organizations, resulting in an agreed range of effort-sharing parameters. Based on this, we quantified each country’s range of fair shares of 1.5°C-compliant mitigation, using the Climate Equity Reference Project’s allocation framework. Contrasting this with national 2025/2030 mitigation pledges reveals a large global mitigation gap, within which wealthier countries’ mitigation pledges fall far short, while poorer countries’ pledges, collectively, meet their fair share.

We also present results for individual countries (e.g. China exceeding; India meeting; EU, USA, Japan, and Brazil falling short). We outline ethical considerations and choices arising when deliberating fair effort sharing and discuss the importance of separating this choice making from the scholarly work of quantitative “equity modelling” itself. Second, we elaborate our approach for quantifying countries’ fair shares of a global mitigation effort, the Climate Equity Reference Framework. Third, we present and discuss the results of this analysis with emphasis on the role of mitigation support.

In concluding, we identify twofold obligations for all countries in a justice-centred implementation of 1.5 °C-compliant mitigation: (1) unsupported domestic reductions and (2) engagement in deep international mitigation cooperation, through provision of international financial and other support, or through undertaking additional supported mitigation activities. Consequently, an equitable pathway to 1.5 °C can only be imagined with such large-scale international cooperation and support; otherwise, 1.5 °C-compliant mitigation will remain out of reach, impose undue suffering on the world’s poorest, or both.”

Equity is the Missing Key for Climate Roadmaps

In March of 2017, Johan Rockström, the author of Big World, Small Planet: Abundance within Planetary Boundaries, along with a extremely high-tone list of co-authors, published A roadmap for rapid decarbonization in Science.  In it they propose a “roadmap” of escalating actions from now until 2050, designed to keep the average global temperature change under 2° Celsius, with some chance of limiting it to 1.5°C.

It’s an important piece, and its bottom line, as scientist and critic Kevin Anderson put it, is that the Rockström et. al. have “upped the ante.” In particular, they have translated carbon-budget science into a specific, decade-by-decade plan for a greatly accelerated global technological transition, driving net global CO2 emissions down to a near-zero level in 2050 – a mere 33 years. This type of planning is crucial as policy makers everywhere wrestle with the immense challenges of meeting the collective goals they agreed to in the Paris Agreement. However, a key element is missing from Rockström’s roadmap: equity.  More specifically, they have nothing to say about the fair sharing of climate action among countries. The bottom line here is that we can’t hope to succeed unless this challenge, too, is taken up, so its omission from Rockström’s paper is unfortunate.

Kelly Stone, a senior policy analyst at Action Aid USA, and I replied in the Huffington Post, in a piece called Equity is the Missing Key for Climate Roadmaps.  Among other things, we said that:

“Morally, there’s no question that developed countries must take the lead, and also assist the poor in the extremely challenging decades that lie ahead. Developed countries including the United States have been emitting far more carbon for far longer than developing countries, and they are, moreover, the homes of most of the world’s wealthy. The top-line message here could not be more clear, for the richest 10% of the world’s people produce half of Earth’s fossil-fuel emissions, while the poorest half contribute a mere 10%. This is the essential background without which it’s impossible to understand the position today, in which we’ve used up essentially the entire global carbon budget, and, to note the sharpest part of the challenge, developing countries face an urgent need to leapfrog to renewable energy even as many of their citizens still lack basic energy access, let alone proper health and education systems. Even worse, people in the global south – especially the poorest – are already feeling the impacts of climate crises they did nothing to create. Asking them to take to a roadmap that makes no provision for such facts is simply wrong.

Nor is climate equity just a moral challenge. There are strong instrumental reasons to believe that, unless we put the equity challenge front and center, there’s little hope of following any road as difficult as the one that Rockstrom and his co-authors have laid out. The bottom line here is that, given the emergency situation we’re now facing, developing countries must mobilize on a scale that far overwhelms their capacity to act alone, and they must do so even as rising climate impacts force them to prioritize adaptation. They cannot possibly meet these challenges without support from developed countries, and even in the short term it’s difficult for them to lay the necessary plans without some modicum of confidence that such support will be forthcoming.”

Drawdown is a real step forward, though another is needed

My review  of Drawdown was published in The Nation on May 28, 2017, under the title A New Book on the Climate Crisis Makes the Persuasive Case That We’re Not Doomed,  Not for technological reasons, anyway.”   It richly praises the book, and the effort behind it, then it adds this:

“I must add that Drawdown is not yet a tonic strong enough to cure the dystopian plague that has come to penetrate most all our visions of the future. It illuminates the techno-economic path forward, and it insists that social justice is also a prime concern, but on this second front it offers almost nothing that is concrete, specific and believable. To be truly “comprehensive,” a deep-decarbonization plan must recognize the dire threat which economic stratification poses to our ability to mobilize, and reveal the mechanisms by which we will learn, again, to cooperate. Which is to say that, when it comes to both domestic and global environmental justice, an ethos is not enough. The deeply political, justice-based side of the climate-transition equation needs a lot more attention than it gets here, and it needs it now.

But Drawdown’s catalog of solutions omits long-term democratic planning, which is essential to any true deep-decarbonization roadmap. It makes no mention of the overarching challenge of ensuring a just transition, one in which all those whose lives will be disrupted by the climate transition are, somehow, made whole, or at least whole enough. (Think coal miners, but think too of all the communities and even countries that are dependent on the fossil-fuel economy.) It talks of “net costs,” but it does not talk about winners and losers, as if any acceptable pricing system could gloss over the challenge of today’s obscene level of inequality. There’s no discussion of progressive approaches to climate taxation, without which we haven’t got a snowball’s chance. There’s no mention of cap-and-dividend systems, or energy-subsidy reform, or the international finance and technology support systems that will be necessary if the Paris Agreement is to deliver. Or of fair trade. Or of class.”
