More than 90% of the heat trapped by greenhouses goes into the ocean. But what happens in the oceans doesn’t stay there.

A ‘catastrophic’ super El Nino could form by spring - www.smh.com.au/environment/...

A ‘globally catastrophic’ super El Nino could form by spring

An El Nino typically associated with a hot, dry spring for Australia is likely to form towards the end of winter – and one model rates the chances of a rare super El Nino at 20-25 per cent.

The weakening of the atlantic meridional overturning circulation (AMOC - potentially causing cooler winters in Europe as often explained by @rahmstorf.bsky.social) is only part of the even faster weakening of global ocean circulation that could harm nutrients transport to the sea surface #Antarcic 🧪

Professor Matthew England FAA@profmattengland.bsky.social · 9mo ago

If you’re interested in why the #Antarctic overturning circulation is very likely closer to a tipping point than the #AMOC, I touch on the topic in this 10 minute talk presented virtually today at #COP30. Starts at approx. 20 min mark.

“This is a wake-up call,” said author and ACEAS Deputy Director, @profmattengland.bsky.social (UNSW). “The evidence shows us clearly that the MOC has slowed down, and if this trend continues the impacts on human societies, climate and ecosystems will be profound.”

"The pace of change is already at about a 30% decline. This just tells you how critically urgent carbon emissions reductions are, because we need to give this overturning circulation every chance of not tipping over what seems to be a very perilous & near tipping point" #ClimateEmergency #Antarctica

Why have the sea surface temperature suddenly risen in 2023/24? 🌊 Is it true that climate models cannot simulate such SST jumps? What is common to such jumps? How will SSTs evolve over the next months and years? Are we in uncharted territory? More from our recent study in Nature is here👇

Record sea surface temperature jump in 2023–2024 unlikely but not unexpected - Nature

Observations and climate models suggest that the global sea surface temperature jump in 2023–2024 was not unexpected and would have been nearly impossible without anthropogenic warming.

We looked at impacts of a shutdown of the AMOC on Australia in our Tipping Points workshop report for the National Climate Risk Assessment.

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵
