Climbing through approximately 11;500 feet the Master Warning illuminated along with the Cabin Altitude warning. I turned ATC over to the First Officer; the PF; who stopped the climb and coordinated a descent back to 10;000 feet while I executed QRH emergency procedures. We declared an emergency for an immediate return to our departure airport. There were no further complications and we landed on Runway 8 approximately 10 minutes after receiving the warning.
An MD-82 suffered a pressurization problem climbing out of approximately 11;500 MSL. They declared an emergency; conducted appropriate QRH checklists and returned uneventfully to their departure airport.
