Please help me figure out what's causing the creaks in my DIY loft

Three months ago, I constructed a loft out of 2"x6" and 2"x8" lumber, 5/8" plywood, metal joists, carriage bolts, and decking screws. The day it was built, the loft held our queen sized bed and the weight of three people (500 lbs) without any creaks. Now, the loft creaks every time we get into it.
There are no obvious signs of stress. When people walk up the similarly constructed stairs, there are no signs of buckling. When someone stands on the loft, even if they stand between the floor supports, there are no signs buckling. Visible signs aside, the audible creak seems to be getting worse.
The temperature has dropped enough since September 1 that we run our heat now. My best, but uneducated, guess is that the heat and indoors placement of the wood has caused the wood to dry out over time, which in turn causes the creak to get worse.
Testing shows that the creaky noises come from the junction of the joists, wood and decking screws. I'm trying to determine three things:
1) What's the likely cause of the creaking noise?
2) Is the noise indicative of potential structural failure?
3) What can be done to reduce the noise?
