By Some Estimates, 30% of All the CO₂ Released by Humans

Multiple Choice

By some estimates, 30% of all the CO₂ released by humans in the last two centuries has been absorbed by the world's oceans. As ocean temperature increases, carbon dioxide becomes less soluble (dissolvable) in water. As a result, more CO₂ will stay in the atmosphere where it acts as a greenhouse gas to trap heat and warm the oceans. This is an example of a _______________.

A) negative feedback cycle
B) neutral feedback cycle
C) interspecific interaction
