has anybody mentioned SMOC is very similar to Smok, the polish word for "dragon", also used to name this carnivorous late triassic archosaur: https://en.wikipedia.org/wiki/Smok_wawelski

New over at climatetippingpoints.info: 'News Explainer: Is the AMOC closer to collapse than thought?'
The first of a new occassional 'News Explainer' series, briefly summarising recent news on climate tipping points (and checking how well the media reported it).
First up, a paper by Portmann et al. constraining future AMOC decline, but does it show that collapse is more likely than thought?

Seen a #TippingPoints story recently about the SMOC (the ocean's overturning circulation around Antarctica, i.e. AMOC's southern sibling) abruptly reversing?
Thankfully, it's not true (seems a press release got overenthusiastic).
Want to know what the paper behind it really said? Read this from the lead author instead: https://theconversation.com/completely-unexpected-antarctic-sea-ice-may-be-in-terminal-decline-due-to-rising-southern-ocean-salinity-259743

I was on BBC Radio Scotland last week talking about whether the recent very sunny & dry followed by wet weather in Scotland & rUK has been a case of "weather whiplash" - you can listen in here: https://www.bbc.co.uk/sounds/play/m002cpq0, & read my write-up: https://medium.com/p/82e39321740c

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

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]

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!

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!

I'll be giving the next Cardiff University School of Earth and Environmental Sciences public lecture on November 12th, covering what climate #TippingPoints are, how close they might be, and what we can do about them - come along if you're around Cardiff then!

A good case-study of shifting baseline syndrome - much of Europe was once surrounded by oyster reefs as large and complex as tropical coral reefs, now largely forgotten:

Props to the team who catalogued records of them in this fascinating (but tragic) paper: https://www.nature.com/articles/s41893-024-01441-4

New article up by me and @jamesdyke at @TheConversationClimate on the new #GlobalTippingPointsReport (which I led the first section on Earth system tipping points In) published today at #COP28:
"Climate tipping points are nearer than you think – our new report warns of catastrophic risk" https://theconversation.com/climate-tipping-points-are-nearer-than-you-think-our-new-report-warns-of-catastrophic-risk-219243

Glad to see this paper out from The Earth Commission proposing new quantifications for #EarthSystemBoundaries that are both Safe & Just, for which I've been working on the climate and nutrient boundaries.

@bovine3dom Most Western European farmland is highly-optimised. That would include FR, NL, DE, CH, DK, and probably ES, IT. Nordic countries are effectively fucked for domestic grains production, though they do well for fisheries.
The sustainable energy situation is extrordinarily technical and complex. For an excellent national-level assessment that's appropriate for most of the EU, though it's based on the UK, see the late David MacKay's Sustainable Energy --- Without the hot air. One of his key points is that every BIG bit helps --- small measures such as unplugging personal electronics and televisions are utterly specious. Indigenous energy sufficiency in the UK would require vast renewables infrastructure and tremendous efficiency improvements and net energy curtailments.
Renewables-based imports (e.g., long-distance power transmission from the Sahara, synfuels, or imports of energy-intensive goods) are all but certain to be part of such a mix.
Again: absent marginal intances, ag+solar is a nonstarter. Urban/built infrastructure, floating deployments, and imports are far more sane. To the point this isn't worth discussing. I strongly recommend your reading MacKay.

Wanted to add a link to the late MacKay's book <https://inference.org.uk/mackay/itila/book.html>, which in §37.3 gives several simple examples illustrating the points of that answer. -
