The Session addresses the concept of overshoot - exceeding then returning to or below a level of global warming - in the context of the long term global temperature goal. Overshoot in the IPCC Sixth Assessment Report (AR6) cuts across all aspects of the Climate Change Assessment Of Climate Responses, Impacts, Adaptation And Mitigation. Presentations from authors of the three IPCC Working Groups will discuss how overshoot has been assessed from a conceptual perspective, in future climate and socio-economic scenarios, the implications For climate, including extremes, and for natural and human systems, and the implications for policy development. The session will include an exchange with IPCC authors and policymakers on the state of knowledge, the gaps and needs to inform policy development and the UNFCCC process.
