πŸ“š Quick Study Guide

  • 🌑️ Rising Sea Temperatures: Cause coral bleaching and shift species distributions.
  • 🌊 Ocean Acidification: Increased $CO_2$ absorption lowers pH, harming shell-forming organisms. The chemical equation is: $CO_2 + H_2O \rightleftharpoons H_2CO_3 \rightleftharpoons H^+ + HCO_3^- \rightleftharpoons 2H^+ + CO_3^{2-}$
  • 🧊 Melting Ice Caps: Contribute to sea-level rise and disrupt ocean currents.
  • πŸŒͺ️ Increased Storm Intensity: Damages coastal habitats and disrupts marine life.
  • 🐠 Habitat Loss: Warmer waters and acidification lead to the destruction of crucial habitats like coral reefs and seagrass beds.
  • ⬆️ Sea Level Rise: Inundates coastal wetlands and increases erosion.
  • 🦠 Disease Outbreaks: Warmer waters can promote the spread of diseases among marine populations.
