Teaching Tips

This could be used in any lesson on climate change, oceanography, marine science, ecology, and chemistry.

It is important that the students understand that ocean acidification is the other carbon dioxide problem.

Ocean acidification, while not directly impacting the climate system, is the result of the oceans soaking up much of the CO2 emitted into the atmosphere, resulting in a potentially catastrophic impact on the ocean ecosystem.
