Unlikely sources of Global Warming

Unlikely source #1: Second Life. (“your average Second Life avatar consumes about as much electricity as your average Brazilian.”)
Unlikely source #2: cows.

The cows are the bigger problem, but I think it’s also worth pointing out that the Internet is a bigger fossil fuel consumer than people realize, because there is a big out-of-sight-out-of-mind thing going on there. Because you have probably never seen a data center, you probably don’t realize that they even exist. Heck, I’ve been a web developer for almost 10 years, and have only seen the computers I work on once.
