Narrative:

Takeoff and climb went normally. Approaching 10;000 ft the cockpit was very warm and the temperature was fast approaching 98 degrees and we were discussing the systems; causes and possible solutions when the flight attendant called and informed me the cabin crew was smelling something throughout the cabin. They said that they could not determine the source. I told them I would get back to them and then gave aircraft control and ATC communication to the first officer while I tried to contact dispatch and maintenance control. After several minutes I finally made contact and discussed the situation.while talking to dispatch and maintenance control; I got another call from the cabin stating that the passengers were also smelling it and that it had become irritating to the eyes. At this point I decided to declare an emergency and return to our departure airport. Maintenance control requested we shut off the right bleed; after descending past FL350; believing the right engine could be part of the problem. With so many things happening; I ended the call with maintenance control told dispatch of my intentions and put my focus on the immediate issues. During the descent many things happened in a short time span; including not being able to control the cabin altitude and a smoke detector in the cabin being activated. We solved the temperature issue; ran the qrc smoke/fire/fumes checklist; the qrc cabin altitude/rapid decompression checklist; and the approach checklist; coordinated with ATC; the cabin crew and made announcements to the passengers. The cabin crew; with the assistance of a deadheading company mechanic; silenced the smoke alarm and began to prepare the cabin for landing. We coordinated with ATC to descend to 10;000 ft as soon as the terrain permitted. At 10;000 ft we removed our oxygen masks; after determining that the cockpit had no fumes; and landed as quickly as possible with no further incident.

Title: Despite write-ups of apparently noxious fumes throughout the B757 on the inbound descent and declarations of concern to the outbound Flight Attendant crew by the inbound crew; the Captain; upon consultation with Maintenance Control; decided to accept the aircraft and continue to the final destination where more intensive maintenance investigation would be conducted. The Flight Attendants agreed to work the trip only reluctantly and the outbound flight declared an emergency due to fumes in the cockpit and cabin during the initial climb.
