You should go read this brand-new paper by a team including my colleague @koelling.bsky.social if you, too, like to ponder: - Why is the Labrador Sea so darn good at oxygenating the deep Atlantic ocean? - What's the fate of deep ocean oxygen if #AMOC shifts?

🌊 New study shows timing of CO₂ cuts is the main driver of sea-level rise variability by 2065–2075; unless Antarctic Ice Sheet tipping points are triggered… Rapid decarbonisation + adaptation are both crucial to manage sea-level rise risks www.nature.com/articles/s41...
nature.com
The interplay of future emissions and geophysical uncertainties for projections of sea-level rise - Nature Climate Change
Unclear emissions and ice-sheet processes drive uncertainties in future sea-level rise. The authors show that the timing of emissions reductions drives the uncertainties during the twenty-first century, but geophysical uncertainties become more important with time, especially under optimistic scenarios.

Key points: A gap-filling reconstruction of Lake Superior pCO₂ was trained on underway data. Annual lake-air CO₂ flux alternated between net efflux and influx over 2019–2023. Lake Superior's carbon budget demonstrated improved agreement of measured and modeled carbon fluxes.
