Natural gas has gained upside momentum in recent weeks thanks to colder temperatures that have gripped much of North America.

Joel South of The Motley Fool and I debate the issue and try to give investors an array of pro and con issues to keep in mind heading into the New Year. Some natural gas names to consider are Cabot Oil (NYSE: COG) and Dynergy (NYSE: DYN).
