Communicating the Climate Crisis: Introduction to the Thematic Block

Summary/Abstract: In October 2025, Nature reported that the first climate tipping point – defined as the threshold at which small changes precipitate large and irreversible consequences – had been crossed, with the dying off of coral reefs marking this critical juncture (Tollefson 2025). Coral reefs are vital ecosystems, supporting approximately one-quarter of marine biodiversity and sustaining the livelihoods of nearly 1 billion people around the world. The information published by Nature drew upon the Global Tipping Points Report 2025 (Lenton et al. 2025), which provides the scientific basis for these claims. When considered alongside observable phenomena like the ever more intense heatwaves, widespread wildfires, catastrophic flooding, and record-breaking temperatures across Europe and elsewhere in recent years, the accumulating evidence of an escalating climate crisis has long been apparent. Correspondingly, the media has paid greater attention to these developments, reflecting the issue’s pressing urgency.
