iCal "sees" my gmail calendar with no permissions

I have not given permission anywhere in gmail, iCloud, or iCal itself permission to see my gmail account's calander entries. My apple ID is completely unrelated too, as this is a yahoo based. I dont even own an iPhone.

Yet there they are, right on my iCAl, in all thier creepy glory.

A search only reveals people wanting to ADD google calander to thier iCal. I have the opposite problem and it is really annoying. I want to know HOW this software knows about all my gmail calander events if i never have linked them?

Secondly, how do i disassociate this connection.
