yet another positive feedback loop related to our rapidly warming climate is being investigated here at CU - Boulder.
fyi - positive feedback loops (not necessarily "positive") are mechanisms by which a certain action affecting a system serves to perpetuate the conditions it started and continue perturbations in a system. these feedbacks send systems into states of chaos - amplifying the original perturbation. this is the opposite of a negative feedback, in which perturbations are held in stable equilibrium. these various feedback loops are riddled within our global climate system, and provide the basis for much research (and arguments) concerning climate change.
