This contribution considers the world-historical significance of climate change. Climate change unmasks the stability of the living and acting in the world of human and nonhuman existence and confronts it with its living and acting on Earth, shifts the attention from World to Earth, and raises the question about the place of human and nonhuman existence on Earth. To answer this question, this chapter moves beyond humanist and post-humanist positions and argues for earth and world interest in times of climate (...) change. First, an ontological concept of World is rehabilitated, which enables to distinguish between the Holocene World and the Anthropocene World. As climate change also confronts with Earth as exterior milieu beyond the interior milieu of the Anthropocene World, the chapter subsequently criticizes the self-interest of philosophers of the twentieth century and argues for world interest in times of climate change. It is argued that world interest should not lead to world production, whether it is found in a productive act by the Earth or by humanity, as world production is accompanied by Earth alienation. A gestalt-based understanding of the givenness of Earth as noncausal ontic-ontological ground of the givenness of World is developed. The conceptualization of World and Earth in this chapter helps to differentiate between the often ambiguous uses of these concepts in environmental philosophy and contributes to contemporary debates in philosophy of climate change.

Technologies are undeniably having a decisive, transformative impact on Earth, yet the currently prevailing empirically orientated approaches in the philosophy of technology seem unable to get to conceptual grips with this fact. Some thinkers have therefore been trying to develop alternative methods capable of clarifying it. This paper focuses on Vincent Blok’s call for rehabilitating an ontologically oriented approach. It reconstructs the rationale of his method as well as its key elements and structure. Elucidating Blok’s emphasis on the experience of (...) climate change, the paper clarifies his call for a terrestrial turn in the philosophy of technology. This turn is indisputably needed, but Blok’s conceptualisation of Earth is problematic: Apart from its speculative nature, it underestimates the impact of humans on Earth. Blok seeks to clarify how ontic phenomena, especially particular technologies, can have an ontological impact, but there is a friction between his Heideggerian concept of the world as grounding inner-worldly beings and the idea of technologies as founding a new world. Identifying the elements where the undoubtedly required ontological approach needs to be rethought, the paper suggests that we need more mundane conceptualisations of both Earth and the world, accompanied by more attention to ontic processes.
