Ocean Acidification and Climate Impact

The video discusses the impact of climate change on oceans, highlighting that over 90% of the heat from global warming is absorbed by oceans, leading to increased temperatures, stronger hurricanes, and damage to marine ecosystems like coral reefs. It explains the Paris Agreement's focus on global temperature and questions its effectiveness. The video also covers ocean acidification due to carbon dioxide absorption, affecting marine life and oxygen levels. It concludes with a call to action for ocean conservation.
