1. Global warming is occurring and is Mainstream; anti-GW belongs in ATM.
2. Human activities (AGW) are a major contributor to GW; the specific contributors and their level of contribution may be discussed, but anti-AGW belongs in ATM.
3. There are other contributors besides AGW; these may be discussed.

Additionally, GW threads in either forum should focus on a particular topic or issue - no more catchall threads, please.
