“Developing negative emissions technology to the point that it's actually capable of meeting global climate goals is essential for temperature overshoot scenarios to be considered viable. But in their new paper, Geden and Löschel say policymakers generally "refrain from any political commitment to developing and deploying negative emissions technologies" at the scale needed for success.
And the lack of urgency may be tied to the fact that there are no clearly defined goals for when or how the technology should be deployed. What is the last year by which global temperatures should be back below a 1.5- or 2-degree threshold? How acceptable is it to overshoot either goal?”

So many negative emissions articles! It's sad that they are all
bound up by consensus reporting, but still--any mention is a good
thing. They are making the conundrum of our legacy emissions
reductions strategies mainstream and now even getting into
overshoot. Very cool ~ ~ ~
One of the conflicts I have always seen with negative emissions
that I have never written about here is, "why do we put negative
emissions last in line for implementation?" I mean, I know "why,"
but why doesn't everyone else understand the leverage of CDR? For
every ton of CO2 we directly remove from the atmosphere, we can
count two tons of CO2 emissions avoided because of natural
sequestration. This is huge. It literally means the the true cost
of CDR, DAC specifically, is only half of whatever it may end up
being once industrialized.
Also relative to true costs, if the Great Spirit wills it and DAC costs are as economic as they appear they could be, $10 or $20 trillion could deal with a teraton of CO2. In World War II, we spent $11 trillion dollars globally in five years on industrial expansion and mostly heavy manufacturing. This spending was 52% of five years of 1938 GDP. Today, $11 trillion is 2.8 percent of 5-years of 2016 GDP. If we spent $11 trillion in ten years, this is 0.3 percent of ten years of 2016 global GDP.
Lord Stern's (2006) annual 1 percent of global GDP for costs of
all emissions reductions strategies (revised to 2 percent in
2008), is $24 trillion ($48 trillion) by mid-century, and does not
decrease atmospheric CO2.

Bruce – just to correct one thing, you don’t get a 2 for one. To reduce the atmospheric burden by 1 ton, you need to remove 2; the natural sequestration is reversible.

Agreed – but there is zero difference to the climate system from not emitting one molecule of CO2, or emitting it and then removing it.
One might say that as long as we still have positive emissions one should therefore do whichever is cheaper, except that since we know we will need negative emissions, we need to develop that capacity even if it isn’t cheaper in the short term.
(And insofar as there are lots of reductions in emissions that don’t cost anything at all, then in the very short term, not emitting the molecule is certainly cheaper, but that won’t be true in the long run.)

This is a very important interchange that a least I have not heard resolved in the climate debate . Namely both statements seem to be correct to me - the ocean sequestration statement is correct but so is the larger feedback issue Andrew raised.

Offshore marine operations can be designed using off-the-shelf equipment which will become self-replicating at the first phase of deployment.
Scale up, for Direct Ocean Capture and Conversion of Carbon (DOC3), is not a limiting factor. The technology basket used by DOC3 operations is credit card ready.
Background notes are available.

So many negative emissions articles! It's sad that they are all bound up by consensus reporting, but still--any mention is a good thing. They are making the conundrum of our legacy emissions reductions strategies mainstream and now even getting into overshoot. Very cool ~ ~ ~
One of the conflicts I have always seen with negative emissions that I have never written about here is, "why do we put negative emissions last in line for implementation?" I mean, I know "why," but why doesn't everyone else understand the leverage of CDR? For every ton of CO2 we directly remove from the atmosphere, we can count two tons of CO2 emissions avoided because of natural sequestration. This is huge. It literally means the the true cost of CDR, DAC specifically, is only half of whatever it may end up being once industrialized.
Also relative to true costs, if the Great Spirit wills it and DAC costs are as economic as they appear they could be, $10 or $20 trillion could deal with a teraton of CO2. In World War II, we spent $11 trillion dollars globally in five years on industrial expansion and mostly heavy manufacturing. This spending was 52% of five years of 1938 GDP. Today, $11 trillion is 2.8 percent of 5-years of 2016 GDP. If we spent $11 trillion in ten years, this is 0.3 percent of ten years of 2016 global GDP.Lord Stern's (2006) annual 1 percent of global GDP for costs of all emissions reductions strategies (revised to 2 percent in 2008), is $24 trillion ($48 trillion) by mid-century, and does not decrease atmospheric CO2.

"why do we put negative emissions last in line for implementation?"This question discussed below by Peter Eisenberger and Bruce Melton should be the central question in climate politics. However, the failure to address negative emissions in public debate illustrates a failure of human psychology. The main problem is an inability to discuss the evidence that should inform public policy when the evidence conflicts with widely held assumptions. When people feel a crisis may be overwhelming they tend to only tinker at the edges, unable to engage strategically with the big picture.To achieve the two degree target, let alone the 1.5° aspiration of the Paris Accord, the world must remove about 6000 GT of CO2e from the air this century. However, the emission reduction plans presented at Paris would remove less than 1% of this stability target, reducing total carbon level by only 60GT of CO2e over its implementation period to 2030.That disparity between means and ends means that all the achievements of Paris are essentially useless for climate stability. We have a broken paradigm. But worse, the emission reduction achievements are harmful to the climate, because they deflect attention and investment from strategies aimed at the other 99% of the stability requirement, which can only be achieved by physical removal of carbon from the air in much larger quantity than total addition.Why is the policy framework so fractured? To answer that difficult question requires analysis of climate politics. People tend to see scientific questions through a political prism. There is no question that climate science is settled, but that does not at all imply that the science is settled on climate response, the priorities of addressing global warming.Attitudes about what to do reflect people’s values and commitments, and in these areas, people are tribal. Concern about environment and climate is primarily on the left side of the political spectrum, while support for fossil fuel extraction is mainly on the right side of the spectrum. The unfortunate results of this polarity include that people develop tribal attitudes about the moral worth of opposing political positions. We are all aware of the crazy denial of science from right wingers. The climate lobby has also formed a strong political ideology, centred on the false idea that emission reduction is the main climate agenda.What is wrong with that? It confuses the means and the ends. Emission reduction is justified in political ideology by the fallacy that it is the only way to achieve the end of climate stability. However, as I explained above, the numbers show it won’t work. The real 'terrifying new math' of global warming is that everything we can do to reduce emissions will still leave the amount of carbon in the air remorselessly increasing. In paradigm terms, that is called an anomaly. But rather than explore this logic without emotion, the tendency is to double down and treat the supposed means as an end in itself.Symptoms of this confusion include first, the belief that attacking fossil fuels is central to stopping climate change, even though many countries will continue to use emitting energy at high level regardless of climate agreements. The election of Trump shows the capacity of climate politics to mobilise reaction, illustrating that attacks on fossil fuels will encounter vigorous opposition.Second, the IPCC, as the home of climate ideology, has apparently defined climate mitigation as only achieved through emission reduction, even though emission reduction does almost nothing to mitigate climate change. The real priority for mitigating climate change should be carbon removal.Third, and worst, there is a widespread attitude among climate activists, whether overt or covert, that actions to insure against climate change by removing carbon from the air should be opposed because they undermine political pressure to achieve emission reduction. Questioning emission reduction is as politically deplorable as questioning gay marriage.The sad fact is the means has completely displaced the end in climate politics. The result is that it seems the climate movement is more concerned about building a popular left wing political front against fossil fuels, based on the failed emission reduction paradigm, than actually stopping climate change. It is as though the old political battles of the last century between socialism and capitalism have subconsciously been used as the map for climate politics.Unfortunately, this focus on political conflict is a recipe for disastrous ongoing warming. It is even possible the fossil fuel industries and their allies could install military governments in some countries if elected governments insisted on policies that would shut them down. Meanwhile the sixth extinction marches on, with the collapse of planetary biodiversity and extreme risks to economic and climate stability.My view is that this conflict on climate policy can be overcome if carbon removal is accepted as a strategy for a unified approach, presenting ways for fossil fuel industries to work in cooperation with climate science by investing money, resources, skills and political support in carbon removal, with a main focus on marine biology.If new technology can be developed that can remove more carbon from the air than total emissions, emissions can continue, and there is no need for emission reduction. That would even mean the stock price of coal could be sustained.Negative Emission Technology is last in line because it undermines emission reduction and destroys the political strategy of a popular front against fossil fuels, both of which are considered more important by the climate lobby than actually doing anything about global warming.Robert Tulip

Great additions Robert. Where did you find the 6,000 GT CO2e? Hansen
2017 has 860 ppm CO2 and 4 C warming, at 4660 Gt CO2. I
guess these are about the same but I would like to have the ref
for my archive.
Let me link the climate culture dilemma you have described to the 2:1 negative emissions leverage concept and a couple of other global warming psychology things...
The cost of delay and 6,000 GT CO2e by 2100 speaks directly to
the negative emissions leverage concept. The atmospheric removal
vs. emissions avoidance ratio--in time frames that matter--is
not 1:1 as it is in longer time frames. It approaches 2:1
because time frames that matter are at most 10 to 20 years. If
we did it all today, removal would be 1,000 Gt. If we wait, five
times more. Because half of emissions are basically
instantaneously removed from equation (not physically, but
through accounting and relative scale of emissions over loading
and natural removal), 1,000 GT atmospheric removal this
afternoon is equal to 2,000 Gt emissions. If we do it all in 10
or 20 years, we only have fifteen percent of emissions and
feedbacks to deal with and return of already sequestered CO2 is
small until we get to multiple generations.
On the Efficacy of Emissions Reductions: Annual missions are only (+/-) 3.6 percent of atmospheric loading. When half of emissions are naturally sequestered (again--instantaneously), this means annual emissions are only 1.8 percent of what is doing the warming.
I want to add a little about climate tribalism too, relative to
"Support for fossil fuels is primarily conservative." This is
true in the broadest terms. When looking directly at public
thought though, north of 70 percent believe climate change is
real, north of 50 percent believe it is caused by man and
importantly, north of 70 percent believe we should have carbon
regulations (Yale
Climate Opinion Maps.) These numbers are national and
astonishingly similar from state to state--even in deep blue
states ( y'all
gotta see these maps!--
they are broken down by county and congressional district too!)
So there is ample support for policy. It's time frames that are
the challenge once again. The challenge is that widespread
thought says "it's just climate change--no big deal, we'll
figure it out before it's too late..."
The Moral Imperative: It's driven not just by advocates, but by
likes of the keyboard player in the most important climate
change band on Earth who is definitely not an advocate; he's a
transportation engineer, nothing more (except for a jammin
keyboard player.) "Keys" thinks CDR, DAC, geoengineering and
etc. are all attacks on Mother Nature. Mess with Mother Nature
and we lose--every time.
So what do we do?
Thank's to Peter F., we have a brain science tool. If we convince people that we need a healthy climate (who doesn't believe this?), then by definition they must accept very strong negative emissions are needed regardless of risk and cost because strong negative emissions is the only way that a healthy climate can be achieved. We have to back them into a corner with logic and their own needs and wishes. Once they accept that we need a healthy climate, not one that is borderline dangerous or however dangerous it is today, their own logic prevails upon them to listen lest they conflict with themselves.
Climate Salud,
B

Bruce,
Re your 2:1, you should back that up with references.
Long term, of course, everything we put in the atmosphere gets absorbed by the ocean. The reason that only half of what we emit in a given year adds to the atmospheric concentration is that the *short term* absorption by the biosphere and oceans takes the other half. That’s obviously an over-simplification, but the biosphere part is certainly short time scale, and the ocean includes a broad range of time-scales (see Long Cao’s 2011 paper, for example). The 2:1 estimate for our emissions vs concentration increase is based on what we’ve emitted in the last few decades, so the time-scale is entirely commensurate with time-scale of solving the problem.

Dear Robert--There is sort of a similar discussion going on on the [geo] site. A couple of comments seem needed here as well.
1. The implication in Robert's write-up is that negative emissions can keep us below 1.5 C. For that to happen, given the slow decrease in emissions, the negative emissions likely have to be pulling out of order 10 GtC/yr starting in the early 2020s to keep the CO2 concentration from continuing to increase. That would require quite a phase up.
2. If one looks at the IPCC FOD 1.5 C special report, when they talk about getting back to 1.5 C by the end of the century, their pathways lead to overshoot warming to 2.5, 3, or even 3.5 C or more before eventually being brought back to 1.5 toward the end of the century or beyond. Labeling such pathways 1.5 C is really misleading, as impacts are likely related to peak warming rather than the eventual equilibrium value.
3. Finally, stabilizing at 1.5 C will have very serious impacts, especially given there would have been an overshoot and returning to this value. The IPCC report does not really emphasize how serious I think these impacts will be--we need to be aiming to something like 0.5 C to get to a level where there were not serious impacts being initiated, and to lower than that if we want to try to refreeze the ice sheets. So, this means a good bit more will need to be removed.
I'm all for research on negative emissions, but would just note
that thinking that this type of climate intervention would be
sufficient does not yet seem to me to be justified. I'd be happy
to be proven wrong--that only CDR needs to be added, but I don't
think we are near that point yet.
