warming oceans

Global leaders emphasize the ocean's critical role in climate action as scientists warn of a perilous tipping point. Warming oceans are altering marine ecosystems and increasing climate risks, including dying coral reefs, biodiversity loss, severe floods, and threats to food security.

Scientists discovered that methane in open oceans is produced by microbes under nutrient-poor conditions, a finding that could explain rising oceanic methane levels. Warming oceans reducing nutrient mixing may allow these microbes to thrive, potentially creating a feedback loop that intensifies climate change.
