Atlantic Ocean circulation nearing ‘devastating’ tipping point, study finds
The circulation of the Atlantic Ocean is heading towards a tipping point that is “bad news for the climate system and humanity”, a study has found.
The scientists behind the research said they were shocked at the forecast speed of collapse once the point is reached, although they said it was not yet possible to predict how soon that would happen.
Using computer models and past data, the researchers …

Oh shit...

In the meantime, the direction of travel is undoubtedly in an alarming direction.
“We are moving towards it. That is kind of scary,” van Westen said. “We need to take climate change much more seriously.””

Het blijft contra-intuïtief, maar doordat de aarde opwarmt is de Atlantische Oceaan op weg richting een kantelpunt − zodra het zoete, lichte smeltwater van de Groenlandse gletsjers de Golf Stroom blokkeert, zullen wij in een periode van slechts enkele tientallen jaren extreme weers- en uiteindelijk klimaatveranderingen gaan meemaken, in Noord-Europa wordt het dan veel kouder en Nederland valt daar ook onder. De opwarming gaat ondertussen gewoon door, dit is locaal

Dak Prescott's Price Is Only Going Up — So Why Haven't Cowboys Signed Long-Term Deal?
The Dallas Cowboys are all in on 2024. It’s become increasingly clear that this means less about putting all available resources into the upcoming season and instead using it as a tipping point for the team's future. Finally get that playoff success that has escaped the franchise since the 1995 season (the last season they won the Super Bowl or even appeared in the NFC Championship Game)? Great! Keep the band together and spare no expense. Falter again in the playoffs in the divisional round …

Machine-learning prediction of tipping and collapse of the Atlantic Meridional Overturning Circulation
Recent research on the Atlantic Meridional Overturning Circulation (AMOC) raised concern about its potential collapse through a tipping point due to the climate-change caused increase in the freshwater input into the North Atlantic. The predicted time window of collapse is centered about the middle of the century and the earliest possible start is approximately two years from now. More generally, anticipating a tipping point at which the system transitions from one stable steady state to anothe…

Not getting into an argument over a #RandomPedantry point, but as a matter of objective fact, we are leaving our kids cleaner air on a global basis than we inherited with the exception of CO2 levels. Sulfur, fine particulates, NOx, etc. are all *down* in a multi-decadal scope.

"A collapse of the current—called the Atlantic Meridional Overturning Circulation or AMOC—would change weather worldwide because it means a shutdown of one of the planet's key climate and ocean forces. It would plunge northwestern European temperatures by 9 to 27 degrees (5 to 15 Celsius) over the decades, extend Arctic ice much farther south, turn up the heat even more in the Southern Hemisphere, change global rainfall patterns, and disrupt the Amazon"

Ocean system that moves heat gets closer to collapse, study says
An abrupt shutdown of Atlantic Ocean currents that could put large parts of Europe in a deep freeze is looking a bit more likely and closer than before as a new complex computer simulation finds a “cliff-like” tipping point looming in the future. A study in Friday's Science Advances finds a long-feared nightmare scenario, triggered by Greenland’s ice sheet melting from global warming, still is at least decades away if not longer, but maybe not the centuries that it once seemed.

I think AWS charging for IPv4 addresses could be a noticeable tipping point for IPv6 adoption amongst the few laggards who have so far resisted.
It's crazy that in 2024 Backblaze B2 still doesn't have IPv6 for its object storage, and here is someone who moved their business away because of the increased costs to talk to it from AWS on IPv4.

Fascinating... Hunga Tonga had a (small) net _cooling_ effect on the climate, despite the big dollop of water vapour it injected into the stratosphere:

Nvidia reports enormous revenue as AI hits a tipping point

Jensen Huang, the Nvidia chief executive, said on Thursday the AI market had hit “the tipping point”. He added: “Demand is surging worldwide across companies, industries and nations.”

Indoor Positioning in 5G-Advanced: Challenges and Solution towards Centimeter-level Accuracy with Carrier Phase Enhancements
After robust connectivity, precise positioning is evolving into an innovative component of 5G service offerings for industrial use-cases and verticals with challenging indoor radio environments. In this direction, the 3GPP Rel-16 standard has been a tipping point in specifying critical innovations, followed by enhancements in Rel-17 and Rel-18. In this article, we elaborate on the 5G positioning framework, measurements, and procedures before shifting the focus mainly to recently identified carr…

Critical Slowing Down in a Real Physical System
The behavior of a dynamical system can exhibit abrupt changes when it crosses a tipping point. To prevent catastrophic events, it is useful to analyze indicators of the incoming bifurcation, as the divergence of the relaxation time of the system when approaching the critical point. However, this phenomenon, called critical slowing down (CSD), is hardly measurable in real physical systems. In this paper we provide experimental evidence of CSD in a laser system crossing the emission threshold and…

Early warning signals of the tipping point in strongly interacting Rydberg atoms
The identification of tipping points is essential for prediction of collapses or other sudden changes in complex systems. Applications include studies of ecology, thermodynamics, climatology, and epidemiology. However, detecting early signs of proximity to a tipping is made challenging by complexity and non-linearity. Strongly interacting Rydberg atom gases offer a model systems that offer both complexity and non-linearity, including phase transition and critical slowing down. Here, via an exte…

A generalised sigmoid population growth model with energy dependence: application to quantify the tipping point for Antarctic shallow seabed algae
Sigmoid growth models are often used to study population dynamics. The size of a population at equilibrium commonly depends explicitly on the availability of resources, such as an energy or nutrient source, which is not explicit in standard sigmoid growth models. A simple generalised extension of sigmoid growth models is introduced that can explicitly account for this resource-dependence, demonstrated by three examples of this family of models of increasing mathematical complexity. Each model i…

"Right to Buy"
I have a theory that "Right to Buy" was an underlying tipping point for Brexit. If people had still been able to get a council house, they'd have been a lot less antsy about immigration.
If so, it's a great irony that Thatcher's big idea on housing reversed her big idea on Europe. She'd have hated that.
Also, didn't realise it had already been abolished in Scotland & Wales! Good.
