🌊 Surprisingly stable: nitrous oxide emissions only vary by 17% during ENSO events in the Eastern Tropical Pacific.

In our new preprint, we identify the mechanism behind the limited variability — and discuss the importance of this mechanism in the future. 🌎

🌊 #EGU25

Jens, congratulations on this well-deserved recognition! It’s a pleasure to be your companion on this journey. Our conversations often challenge my critical thinking and cause me additional work, but I always leave with a deeper understanding. I guess that’s what it’s all about. Thank you!

The ocean may be absorbing less carbon, but it may not be due to climate change—yet The ocean has absorbed about 30% of carbon dioxide emissions from human activities since the Industrial Revolution, significantly slowing the pace of climate

A new ocean modeling study by HOLLY OLIVAREZ, NICOLE LOVENDUSKI, et al. suggests that recent slowdowns in carbon absorption may be due to natural variability instead of global warming. But a definitive answer requires more frequent & wider sampling of ocean chemistry www.colorado.edu/today/2025/0...

Good morning #EGU25!

Do you want to know what the record high sea surface temperatures did to the ocean carbon sink?

Come and see me after the coffee break (11:35) in Room C:

My #EGU25 starts w/ a session on global budgets and drivers of greenhouse gases with solicited talks by
@jens-d-mueller.bsky.social on the ocean sink under record high SST in 2023/4
Santiago Botía on what it meant for the drought in South America and land sink in the Amazon, Cerrado and Caatinga

Introduction slide for a presentation called 'Towards sustainable nutrient management along the Land-Sea continuum, an integrated modeling perspective!' The slide displays the title and the list of authors (G Laruelle, A. Casquin, M. Silvestre, A. Capet, P. Regnier, V. Thieu) over a background representing the coastal ocean. The slide also includes logos of different institutions (FNRS, Sorbonne University, Université Libre de Bruxelles), laboratories (BGEOSYS and METIS) and funding agency (OFB: Office Français de la Biodiversité) as well as one representing the name of the project: Nuts_STeauRy.

🌊Off to Vienna for my first EGU since 2017!
If you're there, please, drop by room 2.23 on Friday at 14h for my talk 'Towards sustainable nutrient management along the Land-Sea continuum, an integrated modeling perspective!'

Highlighted event: Opening up about Mental Health across Career Stages in the Geosciences EGU 2025 is almost upon us! While a highlight of the year for many scientists, a big conference like this can also come with feelings of stress or anxiety for many. (If that’s you – you are not alone!...

Internal variability effect doped by climate change drove the 2023 marine heat extreme in the North Atlantic Communications Earth & Environment - The 2023 North Atlantic marine heatwave was driven by an extreme phase of internal atmospheric variability but would have been impossible without the doping...

🌊 The N.Atlantic has been experiencing extreme T°C in 2023. This situation raises a number of questions: Have we missed something? Do climate models allow us to understand such an event, or have we entered a new climate regime?
We attempted to answer these questions in this study:

Annual increase in atmospheric CO2 in the marine boundary layer (global average). The bars steadily rise from 1960, with quite some interannual variability, but then 2024 is way above all other years (25% higher than the previous record).

A record increase in the global average atmospheric CO2 in 2024, 3.75 parts per million (previous record was 2.96ppm).

The global average is more representative than Mauna Loa, as it is the average of numerous stations located around the world.

Scoop: U.S. delegation pulled from key U.N. climate science meeting The IPCC meeting in China is slated to determine the content in the group's next series of reports.

‼️The US-based @ipcc.bsky.social technical support unit (TSU) for Working Group 3 Co-Chairs has been terminated, and the US won’t be attending next week’s IPCC meeting where the AR7 chapter outlines will be approved.
