Subject: How is quantum decoherence different from the Copenhagen Interpretation?

Under both the Copenhagen Interpretation and decoherence there is "collapse of 
the wave function." Under the first it happens when it is "observed" by a human 
or something else. Under the second it happens when it is "observed" by the 
universe via interaction with a photon. Decoherence still seems to require the 
same "spooky action at a distance" that Copenhagen does; only the distances 
involved are less because decoherence usually happens more quickly. Is this 
right?
