GO-BGC’s Dr. Lynne Talley presented at COP 28.

The ocean takes up more than 90% of the extra heat and 30% of the excess carbon dioxide produced by human activity that is exacerbating climate change. As a consequence, marine oxygen levels are dropping and marine environments are acidifying. These changes stress ecosystems and reduce valuable ice sheets, contributing to sea level rise. But how do we observe these changes throughout the vast oceans? Learn how global deep ocean observations are used to track these changes.
