This paper focuses on an unprecedented bark beetle epidemic in British Columbia, Canada. The epidemic has killed vast areas of forests, with significant impacts to ecosystems and timber-dependent communities. Explanations of this outbreak continue to overlook or underemphasize important actors and relationships. This paper offers a more detailed explanation of the actors and processes involved in the outbreak and associated responses. Political ecology was applied to guide this analysis, emphasizing both the ecological and social factors involved. Research methods entailed an extensive literature review and over seventy interviews with scientists, policy makers, land managers, and elected officials. Findings illustrate how the outbreak involved many actors, beyond bark beetles and trees, and resulted from complex interactions between ecological and social factors. This study also reveals how actors that prioritized short-term economic gains shaped the conditions that fostered the outbreak and continue to constrain responses. This study illustrates how applications of political ecology that give increased attention to ecology are necessary to fully understand the drivers of environmental change.

Abstract
An increasing number of scientists have illustrated how economic growth is an underlying driver of the climate crisis. This article examines how associated levels of excess work, production, and consumption repress human flourishing and drive global warming. Drawing from the work of Herbert Marcuse and André Gorz, we discuss the irrationality of a system of excess work, production, and consumption in terms of unnecessary human repression and environmental destruction. In the context of the climate crisis, this system becomes even more irrational as it threatens the habitability of Earth for humans. We examine work-time reduction and related sufficiency measures as a rational response to the climate crisis.

In December 2022, a scientific breakthrough in fusion energy resulted in widespread media attention with a focus on fusion as a key strategy to mitigate climate change. In this article, we draw from Herbert Marcuse's work on technological rationality to examine fusion technology in this context. We explore if fusion is seen as a way to master nature, if it protects current power relations, and if a focus on fusion might detract attention and resources from alternatives. Illustrating technological rationality, much attention is being given to the potential achievement of fusion energy, it is being championed by already powerful economic actors, and despite that it is unlikely to be ready in time to support necessary climate mitigation, it may be detracting support for more effective and just strategies that already exist. In this context, framing fusion as a solution to climate change represents what Marcuse calls 'one-dimensional thinking'.

Using the concepts of metabolism and metabolic rift as a framework, this paper examines carbon geoengineering technologies as a solution to climate change and explores if it is possible to mend an ecological metabolic rift without fundamental changes in the social metabolic order. Carbon geoengineering technologies have become a key component of scenarios to limit the extent of global warming and are being discussed as a means to sequester carbon and, therefore, mend the carbon cycle. However, most applications of carbon geoengineering thus far do not result in net negative emissions. Strategies to make operations profitable result in neutral or positive, rather than negative, emissions. While these strategies have the potential to reduce greenhouse gas concentrations, the current social order constrains their use and effectiveness. Instead of being applied as part of the solution to climate change, carbon geoengineering is being strategically promoted by the fossil fuel industry in ways that serve to reproduce and maintain the current social order.
