Northern peatlands could seriously complicate efforts to cool the planet, especially after a temporary overshoot of the 1.5°C global warming limit, according to new IIASA-led research.



Summary

A new IIASA-led study reveals that northern peatlands pose a significant threat to climate goals, particularly after a temporary breach of the 1.5°C warming limit. Peatlands, vast carbon reservoirs, are vulnerable to warming, potentially releasing significant amounts of greenhouse gases and undermining efforts to cool the planet. Even a short period exceeding the 1.5°C target could trigger irreversible changes in these ecosystems, turning them from carbon sinks into carbon sources. This research highlights the urgency of aggressive climate action to prevent surpassing the 1.5°C threshold and safeguard these crucial ecosystems.
