Earth's Climate System May Be Approaching Irreversible Tipping Point, New Study Warns
- Scientists from Oregon State University and the Potsdam Institute for Climate Impact Research have identified 16 'tipping elements' across Earth's systems, including the Greenland Ice Sheet, Amazon rainforest, and Atlantic Ocean's overturning current, that could trigger a 'hothouse Earth trajectory' if pushed past critical temperature thresholds.
- Atmospheric CO2 has reached 422.5 parts per million, about 50% higher than pre-industrial levels, with researchers warning that triggering one tipping element could push others closer to their own thresholds in a cascading effect.
- The study, published in One Earth, distinguishes between a 'hothouse trajectory'—a direction of travel that could theoretically be interrupted—and a 'hothouse state,' where the planet would be locked into extreme, sustained heat and seas many meters higher.
- Researchers emphasize the risk must be taken seriously by policymakers, noting that even if fossil fuel burning stops immediately, the climate system could still enter a self-sustaining cycle of warming.
