#1; environmental semiotics chapter revised
Over the last four days I have completed what amounts to an article writing day, the first in the Autumn semester. In the process of taking part in revising the book chapter "Environmental Semiotics", which I co-write with Jonathan Beever, I added some 800 words to the manuscript (we also shortened the title). Moreover, I also composed five bullet points concerning practical implications related to the article "Friluftsliv in Therapeutic Residential Care: When Staff Take Youth Out to Find a Way In", which I co-write with Joakim Jiri Haaland and which has since been published (cf. separate post).

Ethics of CCS paper rejected for NEEN26 event
I have been notified that my paper submitted to NEEN26, the NEEN & ISEE Conference on Environmental Ethics which is to be held at Umeå University, Sweden, October 14-16th, titled "The ethical case against Carbon Capture and Storage (CCS)", has been rejected by the organisers.
This is the second or third time I have had a paper on this theme rejected. For some reason, the ethics of CCS seems to be anathema.

#29; Philosophising with Rocks received
Over the course of last Friday and today I´ve had an article writing day, with work done related to my book review of Interpreting, Communication and Animal Welfare for Biosemiotics. Also, at work, I received my print copy of Philosophising with rocks: Henrik Steffens and the Anthropocene (eds. Benedikt Jager and Marius Timmann Mjaaland), which includes my chapter "Steffen´s early outlook reconsidered. Nature conceptions of the industrial-age Anthropocene".
This brings the number of writing days so far this Spring up to 29, including 20,5 article writing days.

Ecosemiotics and Environmental Philosophy
This presentation examines ecosemiotics´ relation to environmental philosophy: how has it interwoven with other approaches, and how can it support the future of environmental philosophy? We argue that ecosemiotics’ fundamental relationality offers both strong parallels to and novel perspectives on environmental phenomenology, aesthetics, hermeneutics, and ethics, articulating how ecosemiotics can respond to contemporary debates in environmental philosophy. Ecosemiotics’ novel Peircean and Uexküllian representationalism acts as a thread running through environmental philosophical traditions. Researchers have advanced relational perspectives in environmental ethics deeply informed by ecosemiotics, like Beever and Tønnessen, who argue – for example – that accounts of intrinsic value in nature can be strengthened by appeals to biosemiotics accounts of life-worlds. Key figures in environmental philosophy have cited ecosemiotic figures directly, like Merleau-Ponty’s references to Uexküll that anticipate the emergence of ecophenomenology in environmental philosophy. Other contemporary figures have developed ecosemiotic positions in traditional environmental philosophical areas in order to offer novel and more robust articulations, like Tønnessen’s Uexküllian reading of phenomenology, that pursues Merleau-Ponty and the late Husserl along biosemiotic lines. In this presentation, we draw attention to these threads throughout enviornmental philosophy, and anticipate the possibility of a John Deely-esque project of weaving semiotic threads together in environmental philosophy to fundamentally reorient perceptions of the field and to resolve some old tensions (like around disputes on the metaphysics of deep ecology, concerns about deprioritizing human value, and under-evidenced claims about environmental capacities) with the introduction of an empirically-grounded science of signs and meaning-in-environments. Not only does such a project support ongoing research in environmental philosophy, it can furthermore reshape pedagogical approaches to the field, opening space for a re-telling of the history of environmental philosophy that is grounded in the study of signs. Our presentation will conclude with a foray into the possibility of semiosis of artificial agents and its implications for extensions in environmental philosophy beyond mere «natural» environments.

The ethical case against Carbon Capture and Storage (CCS)
SHORT ABSTRACT
Based on ethical considerations, this paper argues against the use of Carbon Capture and Storage (CCS) as a climate mitigation measure. CCS has become increasingly central as a proposed mitigation measure. However, despite the widespread claim and perception that CCS is a necessity, CCS as practiced to date has been found to be net CO2 additive, and the Net Zero goal has been misappropriated by fossil fuel interests. Key arguments against CCS are derived from the perspective of interspecies justice, and from the perspective of intergenerational justice and fairness. In the latter context, CCS exemplifies unfair intergenerational externalization of costs.
PROPOSAL
In the global discourse, CCS has become increasingly central as a proposed mitigation measure, particularly after Net Zero targets were added to the global agenda with full force with the Paris agreement. The Net Zero goal presupposes Carbon Dioxide Removal (CDR), which may involve the use of so-called negative emission technologies (NETs), which in turn in some cases involve CCS. The Net Zero goal has arguably been misappropriated by fossil fuel interests and their allies to promote an agenda that seeks to avoid rapidly phasing out fossil fuels. Despite the widespread claim and perception that CCS is a necessity, CCS as practiced to date has been found to be net CO2 additive (Sekera and Lichtenberger 2020). In the big picture emission reductions from CCS are uncertain, whereas research has established that CCS mitigation measures result in mitigation deterrence and climate delay.
Regrettably, CCS has not triggered much debate in climate ethics. On a general note, I find it disappointing that anthropocentric perspectives predominate in climate ethics given that some of the most prominent philosophers engaged with climate ethics, such as Dale Jamieson (2010) and Peter Singer (2009), are well-known for their work in animal ethics. Still, neither of them emphasize interspecies justice in the context of climate ethics (see also Callicott 2011). Interspecies justice is particularly relevant in ethical discussions about CCS in two ways: Firstly, in so far as CCS policies contribute to allowing continued greenhouse gas emissions and an overshoot in emissions, this will contribute to exacerbate the impact of climate change, including for non-humans. Secondly, in so far as non-humans are harmfully affected by the transportation of CO2 and long-term dedicated geological storage of CO2 in subsurface environments, this is a direct consequence of CCS policies. This point is particularly pertinent in light of recent scientific discoveries concerning life dwelling in deep-sea and subsurface environments, which include animal habitats in the subsurface (Bright, Gollner et al. 2024). Lastly, while future generations is a common concern in environmental ethics, this perspective have not received much attention in the context of CCS. With its required time horizon of at least 10,000 years for underground CO2 storages (Lindeberg 2003), CCS is a perfect example of intergenerational externalization of costs in a climate change context. This arguably makes CCS unacceptable from the perspective of intergenerational justice and fairness. In this context, the lacklustre climate effects of CCS to date, the widespread political willingness to rely on unproven technologies, and the lack of consensus among researchers on acceptable CO2 leakage rates, is especially concerning.
