The carbon dioxide removal gap

First, although most countries have committed to net zero targets, they still provide little information on what role CDR will play in reaching them. Within the NDCs, ambiguities and a lack of transparency lead to wide ranging assessments of not only the land use §ux and implied removals, but also overall emissions levels. These problems are even more apparent with the long-term strategies, which lack any common reporting structure and where underlying scenarios are illustrative rather than formal commitments.

Finally, a recurring concern in the literature is that including CDR in mitigation discussions may deter near-term emissions reductions 38. States, corporations or other interest groups seeking an excuse for doing very little may exploit the fact that CDR can compensate for emissions, overplaying the quantity of removals that may be achieved at some (later) point in time. Indeed, a variety of claims and discursive strategies beyond CDR are used to excuse or delay climate action, which may help political actors resolve the tension between powerful incumbent fossil interests and increasing domestic or international calls for
climate action.

An over-dependence on land-based removals brings risks for land
availability, food production and ownership rights.

Additionally, forest carbon is vulnerable to reversal and expectations that regional sinks can be preserved in the coming decades have been challenged, highlighting the importance of policies that promote sustainable management, prevent illegal removals, and limit the impact of natural disturbances

Aneb cesta pod 2C by znamenala 19% pokles celkových emisí GHG do roku 2030 v porovnání s rokem 2020, CDR je pouhý techno-hopium sen který napomáhá k greenwash. klimatických/emisních scénářů.

There is a weird phenomenon I've witnessed quite often in the climate discourse, and that I try to pin down in the essay linked below. Sometimes it feels like Westerners merely try to calm themselves by saying that they're not going to be the ones who will be affected the worst by climate change. Pure hopium, if you ask me. Everyone will be affected, just in different ways. But to think that the Global North will remain relatively unaffected while the Global South bears the brunt is a dangerous illusion, as this years' summer shows.

MARSHUS: Hopium to je, ale ne kvůli prachu z pneumatik. Jak velká část planety bude neobyvatelná závisí na tom, kolik ještě spálíme fosilního uhlíku. Musíme výrazně omezit spotřebu, cestování, počet aut, populační růst. Vyměnit spalovací motory za elektroauta nestačí.

GOJATLA: elektrický auta jsou hopium a ve skutečnosti to problém (životní styl) neřeší?

ale samozřejmě, můžeš to brát tak že klimatická změna je jediný problém životního prostředí, pak by to sem nepatřilo. jen abys nevylil vaničku i s dítětem.

Starší článek, který dobře shrnuje, proč se pořád nedaří vyřešit klima...

Even when fitted to chimneys – where the carbon dioxide is at least concentrated – carbon capture technologies have proved excessively expensive in both financial and energy terms.
...
However, this issue pales into insignificance when compared to the difficulty of storing any carbon dioxide that is captured.
...
Vaclav Smil, a professor at University of Manitoba and master of sobering energy-related numbers, calculates that if we were to bury just one-fifth of the global carbon dioxide emissions, we would need to build an industry capable of handling twice the volume of stuff as the entire oil industry, an industry that took 100 years to develop, driven by a large and mostly expanding market.
...
“Summing up, the path to least climate impact will require nations to work together to cut global carbon emissions by 45% in just over a decade.
“Such a cut in emissions will require an unprecedented degree of political will and global cooperation…
...
However, after decades of neoliberal politics and economics, only massive sacrifices on the part of the very wealthy are likely to prevent a further drift toward a climate change denying populism among the majority of impoverished citizens.
...
More than six out of every seven people alive today only exist because of the Haber–Bosch process that produces synthetic ammonia (fertiliser) from fossil fuels. Any genuine effort at reversing climate change had to have as its starting point a reduction in the human population at least to the level prior to the (industrial agriculture) “Green Revolution;” less than half of today’s population. Instead – with a great deal of help from religions that implore us to go forth and multiply, and economists that need a new base for the global Ponzi scheme – we have grown our population as fast as agricultural productivity has improved.
...
The choice before us is that we can take action to reverse climate change and a lot of people are going to die. Alternatively, we can do nothing about climate change and a lot of people are going to die. And since nobody has the wisdom or the bravery to make that choice, we can all sit around pretending that some incredibly implausible technology is going to come riding to our rescue… the opium of the people indeed.
