Global variables are accessible to any code making it much more difficult to determine when and where a global is being modified. They can also lead to data-races whenever two threads try to write to the same global at the same time, or one tries to read the global while another is modifying it. The more complex the global the greater the risk.
Globals are not necessarily bad provided they are thread-safe and genuinely represent a truly global concept. If not, use a local variable instead.
