Review Questions

• How does David Archer's research contribute to our understanding of the carbon cycle?
  • David Archer's research enhances our understanding of the carbon cycle by illustrating how carbon dioxide is absorbed by the oceans and its subsequent impact on marine ecosystems and global climate. His modeling efforts demonstrate the significant role that ocean chemistry plays in regulating atmospheric CO2 levels. By studying these interactions, Archer provides valuable insights into how human activities are altering natural processes and contributing to climate change.
• Discuss the implications of ocean acidification as highlighted in David Archer's work on climate science.
  • David Archer's work on ocean acidification emphasizes the harmful effects that increased CO2 absorption has on marine life, particularly organisms with calcium carbonate structures like corals and shellfish. As oceans become more acidic, it disrupts not only individual species but also entire marine ecosystems that depend on these organisms. This shift can have far-reaching consequences for biodiversity and fisheries, ultimately affecting global food security and economic stability.
