I wrote this paper to work how the climate-carbon system could enter a runaway state 👇

Fascinating new paper from Joe Clarke et al., which addresses the question: could the climate-carbon system suffer a self-sustaining runaway feedback? @gsiexeter.bsky.social @ukceh.bsky.social @bolincentre.bsky.social

ESD Ideas: Climate tipping is not instantaneous – the duration of an overshoot matters Abstract. Climate tipping points are not committed to occur automatically upon crossing critical thresholds in global warming, as is often assumed. Instead, it is possible to temporarily overshoot a t...

Crossing a climate tipping point doesn't mean tipping is inevitable - a threshold can be temporarily passed if overshoot is short-lived.

Limiting time over 1.5 °C would considerably reduce tipping point risks.

New Ideas paper from @exeter.ac.uk & UKCEH: esd.copernicus.org/articles/16/... 🧪

New paper in ESD (esd.copernicus.org/articles/16/...) showing duration of overshoot matters for preventing climate systems from tipping. Crossing a tipping point does not equal tipping. Risk reduced if overshoot duration beyond 1.5 °C kept below a century. @coxypm.bsky.social @gsiexeter.bsky.social

📢 Applications welcome for a fully funded PhD project to work on tipping points @utas.edu.au in Australia! Study "Overshoots in Delay Differential Equations" with Dr Courtney Quinn, Prof Michael Charleston and myself (@gsiexeter.bsky.social). Closing date 1st August www.utas.edu.au/research/deg...

🚨 Last chance to submit your abstract for the Global Tipping Points conference - submissions close TOMORROW Wednesday 19 March @pik-potsdam.bsky.social @maxplanck.de

Last week for abstracts! This promises to be an exciting, cross-disciplinary conference with lots of opportunity for discussion on all types of tipping point research

Myself, @ruthchapman.bsky.social and Florian Diekert are covening a session on 'Early Warning Signals for Tipping Points: From Detection to Action' at the Global Tipping Points conference 30th June-3rd July 2025, Exeter. Just 1 week left to submit abstracts global-tipping-points.org/conference-2...

Exeter Climate Conference

A date for your diaries: 2-4 July, the Exeter Climate Conference "...will present cutting-edge research related to climate change and its impacts, and discuss possible solutions"

I am convening a session with @paulritchie.bsky.social (University of Exeter) and Florian Diekert (University of Augsburg) on ‘Early Warning Signals for Tipping Points: From Detection to Action’. We welcome all abstract submissions and look forward to an interesting discussion around this topic.

Global Tipping Points Conference 2025

This conference is a ‘call to action’ to the research community, policymakers, and business to raise awareness and understanding of the importance of tipping points and to accelerate the required action.
