Carbon Sequestration

• 𝘾𝘼𝙍𝘽𝙊𝙉 𝙈𝙄𝙏𝙄𝙂𝘼𝙏𝙄𝙊𝙉 𝙏𝙀𝘾𝙃𝙉𝙄𝙌𝙐𝙀𝙎:

  • restoration of natural habitats
  • artificial mixing of ocean layers
  • ocean fertilisation (iron and urea)
  • carbon sequestration
  • renewable energy sources
  • afforestation
  • regenerative farming
  • restoration of peat bogs
  • carbon capture and storage (CCS)
  • COP agreements
• Restoration of natural habitats involves restoring degraded ecosystems to their original state, such as reforestation or wetland restoration.
• Artificial mixing of ocean layers is the process of injecting nutrients into deep water to stimulate phytoplankton growth and carbon absorption by marine organisms.
• Ocean fertilization refers to adding iron or other nutrients to the oceans to promote algal blooms that absorb CO2 from the atmosphere through photosynthesis.
• Artificial mixing of ocean layers is the process of artificially increasing nutrient levels in deep water by adding iron or other minerals from ships or aircraft.
• Ocean fertilization refers to the addition of nutrients like nitrogen and phosphorus into oceans to stimulate algal growth, which can absorb carbon dioxide through photosynthesis.
• Carbon sequestration is the process of capturing and storing CO2 emissions underground or underwater using various methods.
• Carbon sequestration is the process of capturing and storing large amounts of CO2 underground or underwater using geological formations like saline aquifers or basaltic rocks.
• Renewable energy sources include wind power, solar power, hydroelectricity, tidal power, wave power, biomass, and biofuels.
• Afforestation is the planting of trees on land that was previously deforested or barren.
• Urea can be used as an alternative to iron for ocean fertilization because it contains nitrogen, which is essential for plant growth.
• The main types of carbon sequestration include geological storage (injecting CO2 into rock formations), oceanic storage (dissolving CO2 in seawater), and terrestrial storage (storing biomass on land).
• Mineral carbonation involves reacting CO2 with minerals such as olivine or serpentine to produce solid carbonates that are less likely to release CO2 back into the atmosphere.
• The use of urea instead of iron for ocean fertilization has been proposed due to its lower cost and potential benefits for marine ecosystems.
• Describe different strategies to mitigate the impacts of climate change. [4]

  • mitigation refers to the attempt to reduce or prevent the impacts of climate change
  • using alternative renewable energy sources such as solar, wind or hydroelectric power (HEP) can reduce the reliance on hydrocarbons/fossil fuels, releasing less carbon into the atmosphere
  • carbon capture and storage (CCS) can remove up to 90% of harmful pollutants from power stations, storing it underground or in deep oceans, adding it to the slow carbon cycle
