Most definitely. Ambient humidity can speed up corrrosion but it will happen eventually if there is any opening in the surface protection. Given the age and the fact that it is an electrical connection it looks normal (bad).

Start with a wire brush and remove as much as you can. Then get an old toothbrush and "Baking Soda/Sodium Bicarbonate" and dip the brush in water, then the powder and go after it again until you have a good look at the connection. To be REALLY AND TRULY fixed, you should disssemble and clean everything. The fact that there are several wires in the group means that you have found the one place on the car where all the ground wires terminate. This could make all kinds of things operate better.
