Just out today: The report “A Nordic Perspective on AMOC Tipping” reviews the current state of science on the risk of Atlantic Meridional Overturning Circulation ( #AMOC) shutdown.
Conclusion: it's "a serious risk which requires a dedicated risk management framework".

What was once seen as a distant climate risk is becoming a real security concern. The destabilisation of the Atlantic Ocean circulation #AMOC has national and global implications. In this article, PIK Director Johan Rockström and Iceland’s Climate Minister Jóhann Páll Jóhannsson outline what can be done about it. 👇

Ocean waters are aging? What?
Yes: we oceanographers call 'age' the time since deep ocean water was last in touch with the atmosphere. It is a measure of 'ventilation', deep vertical overturning of the ocean.
Data show this process is slowing: #AMOC slowdown.
That is bad news for climate, and there is a serious risk of the AMOC crossing a tipping point in the next few decades towards an unstoppable shutdown. One of the worst-case climate change nightmares.

Dr Gilbz: *Trump's Greenland Grab is a DISASTER for the climate*
"Yeah yeah yeah, Trump wants the oil, he wants the military bases, he’s a tantrum-prone despot. We know all that.
But what does he really want with Greenland..?"
Some consider the lack of weakening of the currents between Atlantic and Nordic Seas an argument against an ongoing #AMOC weakening.
Here we show why the opposite is true: AMOC weakening causes a temporary increase in Nordic Seas overturning. 🌊

A recent study by Dutch colleagues shows that a shutdown of the Atlantic overturning circulation #AMOC could bring extreme drought to Europe for centuries.
That is a thus far underappreciated risk of climate change.

What would you prefer as your legacy: 3 meters sea-level rise or #AMOC shutdown?
For me the answer is neither. Let's get out of fossil fuels fast enough to minimise both of these very real risks.
