Several Earth system components may be closer to destabilization than previously thought. Crossing critical temperature thresholds could trigger powerful feedback loops - pushing the planet toward a “Hothouse Earth” trajectory.
The new study,published today in One Earth with contributions from Oregon State University, the Potsdam Institute for Climate Impact Research (PIK) and the International Institute for Applied Systems Analysis, reviews climate feedbacks and 16 tipping elements that risk losing stability as warming continues.

More climate action in industry, transport and building sectors needed to meet Paris climate targets: www.pik-potsdam.de
Short summary:
- Residual CO2 emissions from non-electric energy uses are the greatest impediment to limit warming below 2°C or even 1.5° Celsius, the climate targets of the Paris Agreement.
- Beyond a rapid decarbonization of power supply, much greater efforts are required to reduce fossil energy use from the industry, transport and building sectors.
- Due to residual fossil fuel emissions that would remain even with very stringent climate policies enacted from 2020 on, so-called negative emission technologies to remove carbon dioxide from the atmosphere will be necessary to comply with the 1.5°C limit.
- If we do not strengthen near-term climate change mitigation action until 2030, this will increase the dependence on uncertain carbon dioxide removal and is likely to push the 1.5°C target out of reach.
