Climate Change after Net 0

A new study in Frontiers in Science examines what will happen to climate change after net zero.  The UN Climate Panel’s latest best estimate is that there will be no further global warming once we reach net zero CO2 emissions, but the authors say that significant warming could still occur.

The research team assessed factors controlling global temperatures post net zero and offer a framework for better estimating climate change risks to inform future mitigation and adaptation policies, which they say should be urgently addressed at COP28.

Journalists came to this online briefing to hear four of the authors discuss their findings.

Speakers included:

Sofia Palazzo Corner, lead author, Climate Science & Climate Policy PhD student at the Centre for Environmental Policy, and Grantham Scholar at the Grantham Institute for Climate Change and the Environment

Prof Martin Siegert, Professor of Geosciences and Deputy VC at the University of Exeter

Dr Joeri Rogelj, Director of Research, Grantham Institute, Imperial College London

Dr Roland Séférian, Centre National de Recherches Météorologiques (CNRM) and Principal Investigator of ESM2025, Europe’s flagship project for improving Earth System Models

This briefing was accompanied by an SMC Roundup of Comments.
