Fresh of the press, a new study where we investigated the response of the Greenland ice-sheet and AMOC to warming scenarios, in a coupled Earth system model:

Stratification and overturning circulation are intertwined controls on ocean heat uptake efficiency in climate models Abstract. The global ocean takes up over 90 % of the excess heat added to the climate system due to anthropogenic emissions, thereby buffering climate change at Earth's surface. A key metric for quant...

New paper alert! 🌊

What processes control the efficiency of ocean heat uptake under CO₂ forcing?

We show that Southern Ocean stratification and overturning are key, check out our publication in Ocean Science here:

Surface and Subsurface Compound Marine Heatwave and Biogeochemical Extremes Under Climate Change Extreme conditions in temperature, acidity and oxygen frequently coincide at the sea surface and in large parts of the subsurface ocean Subsurface compound events are often linked to vertical wat...

🌊🔥 Marine heatwaves often do not occur in isolation—they frequently coincide with extreme conditions in ocean acidity and oxygen levels.

In our new paper, we assess the distribution and projected changes of these compound ocean extremes within the top 2000 meters of the ocean.

Ocean Heat Content is increasing faster in two bands around the globe according to a new detailed study. In both hemispheres the warming areas are near 40º latitude and the tropics where it is modulated by El Niño cycles.

When Ice Ages End, Ocean Circulation Fine-Tunes Ocean Heat - Eos New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.

When Ice Ages End, Ocean Circulation Fine-Tunes Ocean Heat - Eos New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.

Researchers present the first record of ocean heat content during the ends of the last four ice ages and the subsequent warm periods. 🧪🌊

By analyzing dozens of ice cores, @mgrimmer.bsky.social @unibe.ch & colleagues learned more about the role AMOC plays in controlling heat uptake by Earth’s oceans. 🌊eos.org/research-spotlights/when...

AMOC Modulates Ocean Heat Content During Deglaciations First ocean heat content (OHC) record covering the last four deglaciations All studied deglaciations show millennial OHC variability anti-correlated with Atlantic meridional overturning circulati...

Does the ocean warm when the AMOC weakens? 🌊 Our new ice-core noble-gas data say it does, at least during the last four deglaciations. A warmer ocean stores a lot of energy but also expands and has lower solubility, which has implications for CO2, sea level, and climate.

Atlantic overturning inferred from air-sea heat fluxes indicates no decline since the 1960s - Nature Communications The AMOC is crucial for the global ocean overturning circulation and controls the climate around the North Atlantic.

Has the Atlantic Meridional Overturning Circulation (AMOC) weakened over the last decades? In our new study, we combine state-of-the-art CMIP6 models and observation-based estimates of the air-sea heat flux in the North Atlantic to show that the AMOC has not declined since the 1960s! 🌊

Abrupt changes in biomass burning during the last glacial period - Nature An increase in wildfire extent and related greenhouse gas emissions can be linked to abrupt climatic changes during the last glacial period.

I'm thrilled to share our new @nature.com paper! We present ice core methane isotope data revealing that past abrupt climate changes likely triggered surges in wildfires, simultaneously driving rapid methane—and possibly CO2—rises 🌎🔥
