Scientists say a crucial Atlantic system is more likely to collapse than previously thought. But the billionaire death cult that steers humanity’s destiny doesn’t do existential crises

The poor and middle pay taxes, the rich pay accountants, the very rich pay lawyers – and the ultra-rich pay politicians. It’s not an original remark, but it bears repeating until everyone has heard it. The more money billionaires accumulate, the greater their control of the political system – which means they pay less tax, which means they accumulate more, which means their control intensifies.

They reshape the world to suit their demands. One of the symptoms of the pathology known as “billionaire brain” is an inability to see beyond their own short-term gain. They would sack the planet for a few more stones on the pointless mountain of wealth. And we can see it happening. Last week delivered the biggest news of the year so far, perhaps the biggest news of the century. But partly because billionaires own most of the media, most people never heard it. We might find ourselves committed to a civilisation-ending event before we even learn that such a thing is possible.

The news is that the state of a crucial oceanic circulation system has been reassessed by scientists. Some now believe that, as a result of climate breakdown changing the temperature and salinity of seawater, it is more likely than not to collapse. This system – known as the Atlantic meridional overturning circulation (Amoc) – delivers heat from the tropics to the North Atlantic. Recent research suggests that if it shuts down, it could cause both a massive drop in average winter temperatures in northern Europe and drastic changes in the Amazon’s water cycles. This could help tip the rainforest into cascading collapse and trigger further disaster.

Amoc’s shutdown is likely also to cause an acceleration of sea level rise on the east coast of the US, threatening cities. It could also raise Antarctic temperatures by roughly 6C and release a vast pulse of carbon currently stored in the Southern Ocean, accelerating climate catastrophe.

Even when the countervailing effects of generalised global heating are taken into account, a further paper proposes, the net impact in northern Europe would be periods of extreme cold – including events in which temperatures in London fall to -19C, in Edinburgh to -30C and in Oslo to -48C. Sea ice in February would extend as far as Lincolnshire. Our climate would change drastically, with the likelihood of far greater extremes, such as massive winter storms. Rain-fed arable agriculture would become impossible almost everywhere in the UK.

Amoc collapse could change Europe’s climate 10x faster than expected. We aren’t ready

Several Amoc monitoring initiatives are at a risk of being defunded and could be discontinued at any moment. While we can’t go back in time to do more observations, we can improve our observation strategy for the future.

Instead, the Trump administration has proposed budget cuts to Nasa, NOAA and NSF – agencies that together provide about 50% of the total Amoc monitoring budget. Last week the US announced the descoping of the Ocean Observing Initiative which was part of a programme observing the Amoc.

The recently launched European OceanEye initiative has allocated €50m for ocean observations and is a great incentive to continue Amoc observations. However, before OceanEye is up and running, the research vessels that service the present-day observing systems will already have to be financed, planned and packed.

In short: monitoring, understanding and forecasting the Amoc is at risk. Without sustained Amoc observations, we cannot know what lies ahead. An Amoc collapse may be imminent, a century away, or, if we act boldly to limit climate change, it might be averted altogether.

For too long, understanding and monitoring the Amoc was viewed as an academic pursuit. Instead, it should now be treated as what it truly is: an urgent, global priority. There is an acute and essential need to construct an alternative international funding strategy to secure long-term Amoc monitoring that realises a robust, continuous and open-access Amoc monitoring program to provide the knowledge to build a safer and more resilient world.

The cost of all Amoc monitoring adds up to about €25m a year. Meaning that for five cents per person per year, the EU can maintain one of the world’s most important climate monitoring systems that impacts our everyday lives and improves resilience to the climate crisis.

We therefore urge the EU, the UK and other international partners to step up, make haste, get organised and collaborate to assure long-term continuation of Amoc monitoring before it is lost.
