As we burn fossil fuels and release carbon dioxide,the temperature of our planet and the oceans will increase.When the oceans warm they will release more carbon dioxide,further warming the planet and oceans.This is an example of a _____ feedback loop and may result in the crossing of a(n)_____.
A)positive;equilibrium
B)positive;disequilibrium
C)negative;equilibrium
D)positive;threshold
E)negative;threshold

This scenario describes a positive feedback loop because the initial change (increase in temperature) is amplified by the subsequent changes (release of more carbon dioxide from the oceans). The term "threshold" is used to describe a point at which a relatively small change can lead to a significant and often irreversible effect, which fits the description of potentially drastic climate changes.
