🌊 New paper out assessing the potential of Ocean Alkalinity Enhancement (OAE) to mitigate the impacts of ocean acidification on marine calcifiers

🌊 In 2023, the ocean carbon sink weakened for the first time in a record-hot year 🌡️🌎
Our new study in Nature Climate Change quantifies this unexpected decline and explains how it came about. 👇

In their new paper GOA-ON EC Members Prof Findlay and Dr Feely conclude that global ocean conditions crossed into the uncertainty range of the ocean acidification boundary in 2020, resulting in significant declines in suitable habitats for important calcifying species

Here's the latest comparison of global surface temperature observations (red) with IPCC climate model simulations (through March 2025, via @hausfath.bsky.social):
Accelerated internal tides in a warming climate
Study suggests that internal tides may propagate more quickly in a warming climate, which could affect energy cascade mixing and marine biological productivity.

Looking at another year of @copernicusecmwf.bsky.social reanalysis data, it still looks like the AMOC is rapidly slowing down.
Northward heat transport through the tropical Atlantic Ocean has decreased significantly.
A decrease of 0.5 PW represents ~16,000,000,000,000,000,000,000 joules per year!
Scientists developed the first climate models in the late 1960s (for which the Nobel Prize in physics was recently awarded!).
How have these models held up against what happened in the real world after they were published? Surprisingly well, it turns out:

The ocean was unusually hot in 2023 👇
We found that this caused an unexpected decline of the ocean carbon sink, primarily driven by anomalous outgassing of CO₂ in the northern hemisphere extratropics.

@NOAA: November 2024 was the world's second-warmest November on record. It is almost certain that 2024 will be Earth's warmest year in NOAA's 175-year global record. Get the latest global #November2024 #climate report: bit.ly/3ZwbeQz #StateOfClimate
There's lively debate on whether and when a tipping point can be ID'd before collapse of the Atlantic Multidecadal Overturning Circulation (AMOC) — but dangerous weakening is expected whether or not a collapse occurs. Part 2 of our two-parter:

Our paper is out! In this study, we investigate how zooplankton, key link in marine food webs, are affected by Ocean Alkalinity Enhancement, a carbon dioxide removal technique for climate protection. www.science.org/doi/10.1126/...
I was just trying to recall how long I've been using earth.nullschool.net in teaching. It's been years, it still works, it's still a beautiful easy-to-use visualization!
We have a new paper out in @science.org today, led by Helge Goessling from #AWI:
The recent global temperature surge in 2023 was intensified by a record-low planetary #albedo

This is what we found (🧵1/8)
A tug-of-war between the natural and anthropogenic signals has led to a near stalling of the AMOC weakening since the early 2010s. 🌊🧪: www.nature.com/articles/s41...
Question: What is your preferred ENSO index? I've started to more heavily lean towards the Multivariate ENSO Index (MEI) versus the Niño-3.4 index or the Oceanic Niño Index (ONI).
MEI seems to better account for the totality of ENSO conditions.

Mesoscale Eddies in the Southern Ocean tend to stimulate the CO₂ uptake in this key region for the carbon exchange between ocean and atmosphere.

What is the advantage of that over using WSL?
Ocean Acidification is reshaping life and biogeochemical cycles.
In our latest study, Niki Gruber and I reconstructed its progression in the global ocean interior over the industrial era, based on our previous estimates of anthropogenic carbon accumulation.
