Does the graph show positive or negative feedback?
Positive, because when the red line shifts, the blue one does also
Negative, because the blue line starts below equilibrium
Negative, because the two actions are keeping each other near equilibrium
Both positive and negative because the graph moves up and down
As the Earth warms, upper layers of permafrost melt, producing waterlogged soil above frozen ground. Methane gas is released into the environment. The greenhouse effect is enhanced. The Earth warms, melting more permafrost.
