Class Footprints in the new Emissions Gap Report

The focus of the 2020 Emissions Gap report is, of course, the emissions gap, which, alas, the pandemic will do little to close. But this year’s edition of this indispensable series also contains a surprise: Chapter 6: Bridging the Gap – the role of equitable low-carbon lifestyles.

The gap itself has been well reported, so I’ll not review it. The crucial numbers are that total emissions reached 59.1 GtCO2e in 2019, leaving us with a gap of 15 GtCO2e to close by 2030, if we would have a 66% chance of achieving the 2°C temperature goal, or 32 GtCO2e if we’re still dreaming about 1.5°C (with the same 66% probability).  Today’s pledges (formally, NDCs) are absolutely not on the necessary scale.

“countries must collectively increase their NDC ambitions threefold to get on track to a 2°C goal and more than five-fold to get on track to the 1.5°C goal.”

Furthermore, most of the pandemic stimulus has thus far been wasted. Globally, Covid related government fiscal spending has to this point amounted to about $12 trillion, a huge percentage of 2020’s global GDP. Unfortunately, a lot of this money has gone into high fossil sectors. The details are more than dispiriting, for they show that many countries have used the pandemic emergency to deepen their support for fossil energy. According to Energy Policy Tracker, the world’s largest countries, grouped into the G20, had (as of December 9th) directed more than $240 billion in stimulus funds to support high-carbon activities and fossil energy, while $157 billion had gone to renewables and low-carbon activities. The US, a particularly egregious fossil funder, had directed over $70 billion to high-carbon activities.

The surprise, and a good reason to go beyond the executive summaries and actually read the GAP Report, is Chapter 6, which focuses on “lifestyle emissions” or, as I prefer, “class footprints.” The first part of this chapter ably summarizes the latest research. The second part is also worth a good look, in part because it offers a master class in just how bland and bloodless analytic prose can get, even when it’s taking on politically fraught matters of absolutely existential significance – like the burden of the rich and their consumption.

Anyway, here’s the takeaway, in a nutshell:

“Around half the consumption emissions of the global top 10 per cent and 1 per cent are associated with citizens of high-income countries, and most of the other half with citizens in middle-income countries (Chancel and Piketty 2015; Oxfam and SEI 2020). One study estimates that the ‘super-rich’ top 0.1 per cent of earners have per capita emissions of around 217 tCO2 – several hundred times greater than the average of the poorest half of the global population.”

The two citations here are essential reading. The Lucas Chancel and Thomas Piketty paper, Carbon and inequality: from Kyoto to Paris, is I suppose a classic, because it came out before Paris. (I reviewed it here). The Oxfam and Stockholm Environment Institute paper, The Carbon Inequality Era: An Assessment of the Global Distribution of Consumption Emissions Among Individuals from 1990 to 2015 and Beyond, is the hot new item, and it deserves far more attention than it has received.

The US Climate Fair Share

The U.S. Climate Action Network has taken a position on the U.S. fair share, which is to say–the US Fair Share in a global emergency effort to stabilize the climate system at 1.5C.  This is a long story, but the position itself is short and sweet. To wit:

“USCAN believes that the US fair share of the global mitigation effort in 2030 is equivalent to a reduction of 195% below its 2005 emissions levels, reflecting a fair share range of 173-229%.”

This position was actually adopted some time ago, on July 17th 2020, when a long “alignment process” led by ActionAid USA, North Carolina Interfaith Power and Light, the Center for Biological Diversity and EcoEquity culminated in the adoption of this position during USCAN’s annual national meeting in 2020.

We’re now going public. The US Fair shares website is at https://usfairshare.org/, and it contains, among other things, a political and technical briefing, which is what you should read if you want the details of this position and its meaning. One point I want to stress is that we’re not saying we have the keys to the kingdom of global climate stabilization. Far from it. We’re just saying we have a critical missing piece, one that spotlights the logic of global climate justice, one that could help make the global climate mobilization fair enough to actually succeed.

There’s some nice early press. Notably, Bill McKibben featured the USCAN fair shares position in his New Yorker Climate Newsletter — in a piece he called The Climate Debt the U.S. Owes the World. I myself placed a longer and more detailed piece in Sierra Magazine called It’s Time for the US to Carry Its Fair Share on Climate Change. Bill’s piece is of course well written, but mine lays out more of the gory details.

And there’s more!  Hunter Cutting has an excellent tweet thread here.  There’s a very informative press release here.  A YouTube of the press briefing is available here.  And, finally, there’s a cool Video

 

Great overview of “tipping points” science

Of all the fraught issues raised by the climate crisis, tipping points–or, more recently, “tipping cascades”–are the most fraught. Pessimism can be self-fulfilling–it comes to that.

And yet there is the truth, which isn’t looking particularly good. Which is why I recommend The Tipping Points at the Heart of the Climate Crisis, which was published a while ago in The Guardian. It’s the best simple overview to the state of tipping point science I’ve seen, and its both up to date and judicious. No “doomsterism” here, but not false comfort either. Rather, simple quotes, as for example when Ricarda Winkelmann of the Potsdam Institute for Climate Impact Research tells us:

‘The 2016 agreement committed most countries to limit warming to 1.5 to 2C . . . Winkelmann argues that 1.5C is the right target, because it takes into account the existence of the tipping points and gives the best chance of avoiding them. “For some of these tipping elements,” she says, “we’re already in that danger zone.”’

I particularly appreciated the straightforward manner in which Michael Marshall, the author of this piece, dealt with the debate about 2018’s “Hothouse Earth” paper, which was itself a tipping point. After its publication, the extent of our danger was palpably clearer. Straightforward like so:

“In 2018, researchers including [Tim] Lenton and Winkelmann explored the question in a much-discussed study. “The Earth System may be approaching a planetary threshold that could lock in a continuing rapid pathway toward much hotter conditions – Hothouse Earth,” they wrote. The danger threshold might be only decades away at current rates of warming.

Lenton says the jury is still out on whether this global threshold exists, let alone how close it is, but that it is not something that should be dismissed out of hand.

“For me, the strongest evidence base at the moment is for the idea that we could be committing to a ‘wethouse’, rather than a hothouse,” says Lenton. “We could see a cascade of ice sheet collapses.” This would lead to “a world that has no substantive ice in the northern hemisphere and a lot less over Antarctica, and the sea level is 10 to 20 metres higher”. Such a rise would be enough to swamp many coastal megacities, unless they were protected.”

Much recommended.

“Fear” vs “Hope” in Climate Communications?

How about brutal honesty?

I live near The Breakthrough Institute (the execrable* one in Oakland), but I remain a definite fan of the The Breakthrough Institute (the admirable one in Melbourne). How could I not when David Spratt, its Research Coordinator, sends out missives like “Fear” versus “hope” in #climate communications. How about brutal honesty?

Read it. It’s basically a tweet stream and it won’t take you long, and it references an admirable chain of comments and papers, all of which any citizen of our frail civilization should be familiar with. The last is from the scientist Kate Marvel, who sums the position nicely in five words. “We need courage, not hope.”

* Is this too harsh? How about “unhelpful”? Is that nicer? In any case, an honest appraisal of the work of the BTI, over its organizational lifetime, would have to conclude that, on balance, it’s existence has been a net negative.

Kevin Anderson on telling the truth

Kevin Anderson, one of the most aggressively truthful of the world’s climate scientists, is well known for his refusal to mince words. More specifically, he’s well known for his willingness to call out his fellows for soft pedaling their real views when they’re speaking publicly. E.g., “On mitigation and particularly cutting emissions in line with Paris, we’re all players in a grand unifying delusion – we’ve become mitigation-deniers.”

Usually, though, these comments are on-the-side. Recently, Andrew Simms, also an unusually productive and creative UK climate activist, sat down with Kevin for a deep dive. The interview, under the title Turning delusion into climate action, was published by Scientists for Global Responsibility. Read it for sure if you’re A) a young scientist, B) wondering about the strategic wisdom of supporting the 1.5C target, which we cannot possibly achieve.

Here’s a sample:

“Not all, but many [climate scientists] had been telling me for years that there’s no hope of staying below 2 degrees centigrade, that we’re heading to three or four degrees. I should add that I disagreed with this view, arguing that if we’re lucky on climate sensitivity and are prepared to grasp the nettle and make very difficult but doable cuts in emissions, then a thin thread of hope remained for staying below two degrees. Today, the chances are much, much slimmer and with the cuts in emissions completely unprecedented and far beyond anything in the public and political debate. What I find most disturbing, is that many of those who previously had told me, away from any microphones, that 2°C was not viable, are now coming out in support of meeting 1.5°C. Worse still, they repeatedly point to idealised technical solutions, yet often with little understanding of either the technologies or their practical delivery, let alone the timelines for making wholesale shifts in technologies and associated infrastructures. “

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
