Going to @EuroGeosciences #EGU25 today? I'll be speaking remotely about Holocene climate stability (and whether or not it means we're in a self-stabilising climate attractor, or just got lucky) & the #HothouseEarth hypothesis at 1620 CEST in Room F1 / online: https://meetingorganizer.copernicus.org/EGU25/EGU25-19647.html

Abstract EGU25-19647

I recently spoke with @jessimckenzi at the Bulletin of the Atomic Scientists for their interesting new special issue on climate hashtag#TippingPoints - lots of great pieces & different views, and you can check out the full interview with me here (including conjuring a new meta-metaphor!): https://thebulletin.org/2025/03/metaphors-can-grow-legs-david-armstrong-mckay-on-tipping-points/
‘Metaphors can grow legs’: David Armstrong McKay on tipping points

David Armstrong McKay is a lecturer and researcher at the University of Sussex and the lead author of a 2022 paper that reassessed the risk of all the tipping elements first identified in 2008.

New blogpost/essay: *On the Point of Tipping*

[some thoughts-in-progress (that ended up quite long) on the uses and limitations of climate tipping points as a scientific metaphor & model]

On the Point of Tipping (or, why tipping points are useful, but should not be reified)

It’s perhaps surprising that it’s taken as many as three whole posts here for me to get on to the topic of tipping points, given my recent academic and outreach work. I’ve been thinking about writi…

Gaia ex Machina - thoughts in progress on people, nature, & the Earth system

Thinking of going to @EuroGeosciences GA2025? We have a session on 'Earth resilience, tipping points and human-Earth system interactions in the Anthropocene' - abstract deadline is Wednesday 15th Jan. 13:00 CET!

https://meetingorganizer.copernicus.org/EGU25/session/51893

Convened by Jonathan Donges along with Lan Wang Erlandsson, Ricarda Winkelmann, Nico Wunderling, & myself. Looking forward to this year's submissions!

Session CL3.2.6

I've got a commentary out today in the new Dialogues on Climate Change journal, summarising progress so far in research on climate #TippingPoints, and reflecting on their implications for climate action & the outlook for future research:

#ClimateChange #OpenAccess

New post from me on recent stories of #CarbonSinks "collapsing" last year & Earth's "buffering capacity" reaching its limits, putting it in context of past trends & future projections. A bit of a lukewarm take by now, but hopefully a useful explainer!

Are Earth’s natural carbon sinks collapsing?

This autumn, several media articles reported on a study showing the global carbon sink on land – which so far has drawn down around a quarter of human carbon dioxide emissions – took up…

Jeff VanderMeer’s surprise fourth book in the Southern Reach trilogy is testing the definition of nature and humanity's place in it.
