Climate Literacy Principle 7D: The chemistry of ocean water is changed by absorption of carbon dioxide from the atmosphere. Increasing carbon dioxide levels in the atmosphere is causing ocean water to become more acidic, threatening the survival of shell-building marine species and the entire food web of which they are a part.

Dr. Salisbury made his concept map a year ago at another COSEE-OS workshop. Reviewing the map at this workshop inclined him to change some things. He felt it was important to realize all concepts on this map can be connected, but thought decreasing the number of connections on this type of map could help to improve its clarity. Working with the informal educators, they decided to start a new map, focusing on how humans contribute to ocean acidification. Geared to an 8th grade level, the team chose appropriate vocabulary, with the size of the circle representing the relative size of that item’s contribution. They also added natural phenomena that contribute carbon dioxide to the atmosphere, and a "So what?" to prompt people to think about ways they can change their own behavior to help mitigate the consequences of ocean acidification.
