Study Notes
- Deep sea coral reefs are threatened by ocean acidification, dubbed as climate change's evil twin.
- Ocean acidification is caused by increased carbon dioxide in the water, slowly killing marine life.
- Ocean acidification has made the ocean 40% more acidic since the Industrial Revolution.
- Marine life, such as shelled creatures, is impacted with thinner shells due to ocean acidification.
- Washington state was the first place where ocean acidification was identified as a threat to marine life, affecting oyster hatcheries.
- Dr. Sebastian Hennige studies ocean acidification's impact on coral reefs, suggesting it causes Coral porosis leading to reef collapse.
- Ocean acidification also affects deep cold water coral, essential for marine ecosystems and biodiversity.
- Indigenous communities like the Iñupiat in Alaska are heavily impacted by ocean acidification, affecting their traditional way of life dependent on seafood.
- Pteropods, tiny planktonic snails, are dissolving in waters globally due to ocean acidification, impacting the entire food chain.
- Mitigating ocean acidification requires reducing carbon dioxide emissions, potentially through methods like seaweed farming and new technologies like ocean-based carbon capture plants.
