Ember: Bubble action from component to application controller

I have a component in ember, which needs to send an action (with one parameter) to the application controller. No matter where this component is rendered, it needs to call the exact same action, on application controller.

application-controller

export default Ember.Controller.extend({
  actions: {
    addAlert: function(message) {
      this.set('message', message);
    },
    removeAlert: function(message) {
      this.set('message', message);
    }
  }
});

How do I handle this? From start, to end.
