... years, rather decades to build. So, in my view, now would be a good time to start planning.

As an afterthought:
Shouldn't we try to capture some melt water in yet-to-be-built artificial lakes until then?

Ten years ago, I'd have had to agree with you telling me that I've read to much sci-fi.
In a world of interdependent #TippingPoints with #BoilingOceans and #CoralBleeching, where the...

Climate Emergency: Feedback Loops is a series of five short films, featuring twelve leading climate scientists, that explores how human-caused emissions are triggering nature’s own warming loops. Viewers learn why natural warming loops have scientists alarmed—and actions they can take. The series is subtitled in 20 languages and available to stream for free. This is a powerful, empowering classroom tool for teaching about climate tipping points.

Exploring the risks of ‘cascading’ tipping points in a warming world

Tipping elements within the Earth system are increasingly well understood.

Scientists have identified more than 25 parts of the Earth’s #climate system that are likely to have #TippingPoints – thresholds where a small additional change in global warming will cause them to irreversibly shift into a new state.

The “tipping” of these systems – which include the Atlantic Meridional Overturning Circulation (#AMOC), the #Amazon #rainforest and the #Greenland ice sheet – would have profound consequences for both the #biosphere and people.

More recent research suggests that triggering one tipping element could cause subsequent changes in other tipping elements, potentially leading to a #TippingCascade.

For example, a collapsed AMOC could lead to dieback of the Amazon rainforest and hasten the melt of the Greenland ice sheet.

However, the interactions between individual tipping elements – and the ways they might trigger each other – remain largely underexplored.

In a review study, published last year in Earth System Dynamics, we unpack the current state of scientific understanding of the interactions between individual tipping elements.

We find that scientific literature suggests the majority of interactions between tipping elements will lead to further destabilisation of the climate system.

Existing research also indicates that “tipping cascades” could occur even under current #GlobalWarming projections.

Scientific understanding of individual #TippingElements is continuously improving, but more research on their interactions is needed.

@StaceyCornelius I absolutely wouldn't rely on this research, or risking giving the impression that "only 3.5% will do". No, we need way more.
After reading A LOT of research on #tippingpoints & #socialchange, I trust Damon Centola's #networkdynamics research which set the threshold at 25%. Here is a very quick video, but I would recommend reading "How Behavior Spreads: The Science of Complex Contagions"

PS: 25% #handsoff is well within reach.

Ça c'est un point de bascule intéressant...

Beaucoup de glace en Antarctique, avec un poids considérable
Qui bloque l'activité volcanique
Si le poids diminue trop elle reprend potentiellement
Ce qui fait encore plus fondre la glace
Ce qui augmente l'activité volcanique

Enfin bref, on va pouvoir récupérer le pétrole là bas 🤬
