Jean-Pierre Gattuso is a French ocean scientist conducting research globally, from the pole to the tropics and from nearshore to the open ocean. His research addresses the biology of reef-building corals, the biogeochemistry of coastal ecosystems, and the response of marine plants, animals and ecosystems to global environmental change. He is also interested in transdisciplinary research, collaborating with social scientists to address ocean-based solutions to minimize climate change and its impacts. He is currently a CNRS Research Professor at Sorbonne University. .. more

- The “CDR tax" is a negative Earth System feedback which opposes the decrease in atmospheric CO2
- The One-Earth CDR framework considers land CDR and marine CDR together within the interconnected Earth System, recognizing that interventions in one reservoir trigger feedbacks in others

This false assertion about the ocean producing 50% of the oxygen we breathe is so widespread that @jpgattuso.bsky.social @bopplaurent.bsky.social and others have written about it here.
Humans will always have oxygen to breathe, but we can’t say the same for ocean life
We are not at risk of running out of oxygen due to climate change, but ocean creatures are – and that will harm the whole planet.

title, authors and abstract of the paper Climate change risks on key open marine and coastal mediterranean ecosystems Abed El Rahman Hassoun1, Meryem Mojtahid, Mohammad Merheb, Piero Lionello, Jean-Pierre Gattuso & Wolfgang Cramer Mediterranean open marine and coastal ecosystems face multiple risks that impact their unique biodiversity, with climate change representing a major ongoing threat. While these ecosystems are also under pressure from non-climatic anthropogenic drivers (e.g., overfishing, pollution), this study primarily focuses on risks related to climate change. To assess these risks and evaluate their confidence levels, we adopt the scenario-based approach of the Intergovernmental Panel on Climate Change (IPCC), relying on a review of literature projecting changes in Mediterranean Sea ecosystems. The main drivers of environmental change are sea level rise, ocean warming and acidification. Similar to global conditions, all Mediterranean ecosystems face high risks under all climate scenarios, with coastal ecosystems being more strongly impacted than open marine ecosystems. For these coastal ecosystems, risk levels are expected to become very high already once global warming exceeds 0.8 °C with respect to the 1976–2005 period. A few Mediterranean ecosystems (e.g., coralligenous and rocky coasts) are relatively more resilient compared to others, probably because of their long evolutionary history and the presence of a variety of climatic and hydrological conditions. However, high-emission scenarios in specific sub-basins, in addition to acidification impacts, could reduce this resilience, decreasing both habitat extent and ecosystem function dramatically. Overall, due to the higher observed and projected rates of climate change in the Mediterranean, compared to global trends, for variables such as seawater temperature and pH, marine ecosystems (particularly coastal) are projected to be under higher risks compared to the global ocean.
