... 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...
The kind of honesty I wish we had more of from our politicians and thought leaders on #ClimateBreakdown.
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.

There's nothing new per se here, but it's nonetheless a saddening read, gaaaaah.

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.

" #Collapse occurs, he argues, when the costs of #complexity are greater than its returns to society. Complex societies are problem-solving organizations, and when the costs of coping with crises are too great, they fail."

@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.

I've long liked Tim, albeit sometimes his incurable optimism irritates me. In his article he rightfully excoriates the Liebs & Nuts, but IMO he is far too lenient on Lab, whose current term has deeply disappointed & frustrated those of us who want climate, environment, & biodiversity prioritised.

‘More frequent, intense’: PM puts climate front and centre for election
Gaaaah, we know all this, you dweeb. We've known it for decades. We also know that you keep funding fossilfools via undeserved obscene tax breaks, & doing their work by approving new fossilfool projects & expansions, plus demonising protesters instead of the actual climate criminals. You simply have NO credibility in this space, dear PM.

Yep, yep, all good, we don't want no pesky clean green renewable energy, pfffft.
In unrelated news, a few days ago yet another fossilfool exploratory licence was granted in Bass Strait. Gotta look after them donors, ahem, owners.

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
Our @OceanIceEU project is launching a whole series of videos in collaboration with @PolarRES to explain key parts of the #IceSheet and #Climate system. In thi sone Tony Payne Payne explains #TippingPoints for #Greenland + #Antarctica.
And he does it really well! Worth checking out...
