During climbout; First Officer's leg; at approximately FL250 the First Officer noticed that the left hydraulic quantity was decreasing. Captain accomplished QRH procedure and subsequently the hydraulic quantity fell to zero. I declared an emergency and returned to the departure airport. We landed uneventfully.
A MD-82's left hydraulic system developed a leak and the quantity decreased to zero during climb out so an emergency was declared and the flight returned to the departure airport.
