Klimaschau 235, presented by the Germany-based European Institute for Climate and Energy (EIKE) analyzes the new “Global Tipping Points Report 2025” and puts the alarmist reports into perspective.
Just in time for the 30th UN World Climate Change Conference in Belém, Brazil, the second “Global Tipping Points Report 2025” was presented by around 100 scientists, including those from the University of Exeter and the Potsdam Institute for Climate Impact Research.
The report warns of so-called tipping points—stages of negative development from which a process becomes irreversible and self-reinforcing. The purpose of course is to spread urgency.
The central message of the report: The 1.5°C warming limit could be exceeded in the next decade, entering the world into a “high-risk phase.”
Tropical coral reefs, especially the massive Great Barrier Reef off the coast of Northeast Australia, serve as one of the central examples in the report. The narrative suggests the reef has been dying since the 1980s due to CO2, heat, medicinal residues, and sediments from agriculture.
However, the video highlights a counter-position. The real dangers to the corals are primarily tropical cyclones, which occasionally devastate parts of the reefs.
EIKE also calls the claim that the thermal tipping point for warm-water coral reefs— 1.2 °C warming above pre-industrial levels—has already been exceeded and the upper threshold of 1.5 °C could be reached within the next 10 years into question.
Natural recovery occurs
Graphics show living coral coverage reveal natural, cyclical variations. A massive die-off around 2010 (cyclone-induced) was significantly worse than current events, yet the corals recovered as nature finds a way back toward equilibrium.
The drop in coral coverage in 2024 (El Niño-induced) also does not provide grounds to claim a tipping point has been reached. The mass mortality is reversible.
Iffy model projections
The dramatic projections that predict coral bleaching—the expulsion of the coral’s plant symbionts due to excessively warm water—will become extremely frequent in the future (up to the 2090s) are based on computer models of sea temperatures and pH values (e.g., CMIP6). Models, especially those used for future projections, are wrong extremely often.
Klimaschau heavily criticizes these models for their “one-sided fixation on CO2” and the resulting “runaway” predictions. It cites NASA researcher Gavin Schmidt, who emphasized that the scientific community must move away from viewing the raw model average as conclusive.
Conclusion
EIKE summarizes in the video that the panic surrounding corals, released shortly before the UN Climate Change Conference, is mostly “flashy headlines but little substance.”
