Impact of Climate Change on Oceans

The video discusses the critical role of oceans in climate change, highlighting their absorption of heat and CO2, which leads to ocean acidification. This acidification impacts marine life, including corals and plankton, and poses a threat to global ecosystems. The video emphasizes the urgency of reducing CO2 emissions and implementing adaptation strategies to mitigate these effects. It calls for global action and policy changes to address these challenges and protect ocean health.
