Achieving net zero greenhouse gas emissions critical to limit climate tipping
Achieving net zero emissions by 2100 is vital to reduce climate tipping risks, with current policies posing a 45% chance of exceeding the Paris Agreement's limits and necessitating immediate action.

Achieving net zero greenhouse gas emissions is essential to mitigate the risks of climate tipping points, which could lead to severe environmental consequences. Current emission trajectories suggest a significant likelihood of temporarily exceeding the Paris Agreement's 1.5°C limit, with projections indicating a 45% risk of triggering tipping elements by 2300 if current policies continue. The study highlights that every additional 0.1°C of overshoot above 1.5°C increases the tipping risk, particularly accelerating beyond 2.0°C. To minimize long-term tipping risks, it is crucial to achieve and maintain net zero emissions by 2100. The research emphasizes the urgency of implementing stringent emission reductions in the current decade to ensure planetary stability. The findings align with international climate policy discussions, particularly the recognition of tipping risks at COP27, reinforcing the need for immediate action to limit global warming and its associated risks.
