Beyond 1.5°C: Living with and ending climate overshoot

As the world enters a period of warming around and above 1.5°C, climate overshoot is shifting from a future possibility to a present challenge. The magnitude and duration of overshoot will shape risks to people, societies, and ecosystems, while some impacts may persist even if global temperatures subsequently decline. Ending overshoot would require not only rapid and sustained emissions reductions, but a transition through net zero to net-negative emissions, raising questions about the scale and feasibility of carbon dioxide removal and how the transformation required can be sustained over decades.

This Cell Press Sustainability Forum will bring together experts across climate science, impacts and adaptation, mitigation, carbon removal, and climate law. Following a scene-setting keynote, the discussion will consider what living through overshoot could mean; why minimizing its magnitude and duration remains critical; what it would take to move from rapid emissions reductions to net zero and ultimately declining temperatures; and how the necessary long-term transformation can be embedded in durable legal commitments.
