Oxygen solubility drops as water temperatures increase. It’s estimated that the ocean’s dissolved oxygen content will decrease by 3-4% by the year 2100.

About CNES

CNES (Centre National d’Etudes Spatiales) is the French Space Agency, a governmental organization founded in 1961. As programme-focused agency and centre of technical expertise, CNES is responsible for shaping and implementing France’s space policy within the framework of international cooperation.

Our action for climate change

The latest Intergovernmental Panel on Climate Change (IPCC) Report released in September 2021, reminds that 26 of the 54 Essential Climate Variables (ECVs) can only be observed from space, to highlight global warming, measure sea level rise or track greenhouse gas emissions. That’s why CNES has made climate actions its priority for years.
