For any who may be interested...
One of the things I've generally seen in emerging/Emergent is a commitment to environmental stewardship that generally is more hands on and feels a bit more urgent than I've usually found either in "pure mainline" or "general evangelical" circles.
If that's true for you, and you're interested in a simple action you might take regarding global warming (though granted, the hands here would be on your computer keyboard), you might consider cruising over to http://www.algore.com/cards.html, take a look at what he's proposing to do (bring a LOT of signatures with him about the need for congress to take concrete action on global warming when he testifies on March 21), and see if that's something you'd want to do.
If it is, then get your hands back on your keyboard and tell a few others. If not-- at least you've taken a look and made a decision.
Peace in Christ,
