Narrative:

On initial climb out off runway 30 during VMC conditions, the first officer brought it to my attention stating, 'we have smoke in the cockpit!' in informed him to declare an emergency and that we would 'wrap it back around' for a visual back to runway 30. We were immediately cleared to land on runway 30, we ran all checklists and landed without incident. The smoke dissipated shortly after it started, however, smoke in the airplane is an emergency regardless of its nature. We taxied back to the ramp and deplaned the passenger. Maintenance found the r-hand air cycle machine (air conditioning pack) frozen and thought that residual grease ignited and produced the smoke through the flows.
