Ocean absorbs less carbon dioxide

The ocean absorbs about 30 percent of human-generated carbon dioxide emissions, but its ability to do so has declined by around 6 percent, according to a new United Nations report.

Climate change impacts ocean’s role

Climate change is reducing the ocean’s capacity to absorb carbon dioxide, as rising temperatures and changes in ocean chemistry, circulation, and ecosystems interfere with this natural process.

Consequences of reduced absorption

As the ocean absorbs less CO₂, a greater proportion of the gas remains in the atmosphere, which contributes to further global warming and climate change effects.

Report released ahead of COP31

The United Nations report was published in advance of the upcoming United Nations Climate Change Conference, known as COP31, to highlight the growing challenges faced by the planet’s climate system.
