Exceeding and returning to 1.5°C: what are the knowledge gaps?
Friday, 1st December 2023
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 will discuss how overshoot has been assessed from a conceptual perspective, in future climate and socio-economic scenarios, the implications for climate, including extremes, for natural and human systems, and for policy development. The session will include discussions on the state of scientific knowledge across disciplines, the gaps and needs to inform policy development, including in relation to response options, and the UNFCCC process.
