Abstract for Lund conference: "Prospective studies of contested climate pasts and futures"
I have just composed the abstract below for the organisers of the upcoming conference "Cognition and Evolution in Historical and Social Research", which is to be held September 23–24, at Lund University, Sweden (I have been invited to contribute).

Prospective studies of contested climate pasts and futures
While most researchers in relevant fields of study may agree that the current scale of human impact on current ecology is massive and unprecedented, there is no agreement on the time frame for the Anthropocene. Like the epoch itself, the current conceptualisation of the Anthropocene remains a work in progress. We are currently situated in the middle of an ongoing climate crisis. On this background, it may come as no surprise that both how we should understand recent modern history, and how we should understand possible climate futures, is contested. In this presentation I will outline how biosemiotics and Umwelt theory can contribute to prospective studies of past and future lifeworlds. I will then proceed to discuss how climate futures may be construed by way of a few examples. The presentation will draw on my articles «The study of past Umwelten» (Discipline Filosophische, 2023) and «What can be known about future Umwelten?» (The American Journal of Semiotics, 2019) as well as my forthcoming book Captured: CCS and the fight for the soul of the environmental movement (Bloomsbury Academic). In relation to Carbon Capture and Storage (CCS), I will touch upon the influence ideas about CCS have had on envisioned climate futures over the last 30 years or so. Disturbingly, there is no consensus among researchers or regulators on the relevant time scales for CO2 storages. Short retention times for CO2 in CO2 storages (<10,000 years) may delay rather than solve the problem of climate change, in effect exposing future generations to the risk of anthropogenic climate change caused in our time. Lastly, I will look into the challenges of long-term waste management in the contexts of radioactive waste and CO2 storage, respectively, including the challenge of communicating across multiple generations.

Abstract for IACS5 (Lund, Sweden): "The crisis of mechanistic science seen through the lens of the nature crisis"
I have just composed and submitted the abstract below for my plenary talk at the 5th conference of the International Association for Cognitive Semiotics (IACS5), to be held in Lund, Sweden in August 2024.

The crisis of mechanistic science seen through the lens of the nature crisis
Morten Tønnessen
Edmund Husserl (1954, 1970) famously thematized science´ forgetting of the lifeworld. In a somewhat similar way, Jakob von Uexküll (1956 [1940]) decried the ´meaning-blind´ biology of his time. Drawing on the fact that the experience of animals is constrained by the sensory and behavioral repertoire of each organism and takes place within the context of species-specific configurations of time and space (von Uexküll 1928), the Umwelt theory he developed was programmatically framed as subjective biology. While he applied the Umwelt perspective to humans as well, particularly in von Uexküll 1956 [1934], unfortunately, human Umwelten remained undertheorized in his work. Hannah Arendt, however, discussed the human condition and observed a crisis within the natural sciences play out as an inability to be relatable to normal speech and thought (Arendt 1958). Although she saw the significance of our evolving global perspective and power, which is today often conceptualized in terms of the Anthropocene (Steffen et al. 2011), Arendt failed to acknowledge the decisive difference our anthropocentric bias makes in matters of ontology and epistemology alike. From the perspective of Umwelt phenomenology, today´s environmental crisis can be conceived of as an ontological crisis (Tønnessen 2003) involving the extinction and marginalization of myriads of lifeworlds. As is well established, the environmental crisis is characterized by extensive anthropogenic environmental change. This can be conceptualized in terms of Umwelt transitions (Tønnessen 2009). The ongoing nature crisis is most blatantly observable in rapidly escalating climate change, and the well-documented marginalization of wild terrestrial mammals, which now account for only 4% of terrestrial mammalian biomass (Bar-On et al. 2018). Arguably, the last decades´ scientific neglect, theoretically and methodologically, of the agency, subjectivity, and worth of living beings has contributed to this intensifying and deepening nature crisis. With its objectivistic, mechanistic perspective on the natural world, the scientific enterprise has in practice facilitated and helped justify a real-life objectification, de-souling, exploitation, and commodification of living beings as mere means and resources. It is high time to replace this outdated and harmful outlook with a philosophically based scientific framework more fit for the 21st century. One way forward entails acknowledging the semiotic agency of all that lives (Sharov & Tønnessen 2023), and start planning for the socio-ecological and economic transformations that will be required to solve the environmental crisis in the next few decades (Tønnessen 2021). This will have to involve a serious rethinking of the human condition (Tønnessen, forthcoming).
