A healthy ocean, a protected climate
According to a study carried out by researchers at the LSCE (CEA-CNRS-UVSQ), by the end of the twenty-first century, seasonal changes in ocean acidification (pH) will be amplified, possibly even doubling. The seasonality of pH levels, which, until now, was thought to be favorable to marine organisms’ ability to adapt to global warming, may in…
The oceans play a major role in climate regulation, especially because they are able to exchange carbon dioxide (CO2) with the atmosphere. Biological processes are helpful for picking up CO2 in the surface waters. Indeed, thank to photosynthesis microalgae elaborate organic carbon by picking up CO2 in the surface waters. Because organic matter is denser…

The Deep -Ocean Stewardship Inititiative (DOSI) and the Deep-Ocean Observing strategy (DOOS), member initiative of the Ocean and Climate Initiatives Alliance (OCIA), will lead during…
The ocean covers 70% of the surface of our planet, it plays a major role in regulating the Earth’s climate and is home to a multitude of species, many of which we have yet to discover. The ocean is crucial for the functioning of life on Earth. With global change, many issues have emerged, and…
After the dramatic consequences of hurricanes Harvey, Irma, Maria and Jose, this year in 2017, understanding the origins of such extreme events is of growing importance. What is the nexus between cyclones, the Ocean, and climate change? Tropical cyclones, also called hurricanes in the North Atlantic Ocean[1], are violent perturbations, or atmospheric depressions. The “eye”…
A new model predicts that French Polynesia will serve as a climate refuge for the survival of coral reefs in the future New climate model projections of the world’s coral reefs reveal which reefs will be hit first by annual coral bleaching, an event that poses the gravest threat to one of the Earth’s most…
