The team behind the documentary "Everything's Cool" (which premiered Saturday morning at the 2007 Sundance Film Festival) isn't just talking about global warming, but trying to do their part to combat it.

Monday morning at 8 a.m., some 800 students from Park City's Treasure Mountain Middle School will help form a message to be photographed by aerial artist John Quigley. The message will be an answer to a similar message, featured in the movie, that was formed by residents of an Alaskan village dealing with thawing permafrost.

Quigley and the film's directors, Judith Helfand and Daniel B. Gold, are still looking for about 100 adult volunteers to join the students. If you're interested, go to the Eccles Theatre at Park City High School and look for the balloon leading you to the field behind the administration building.

Helfand and Gold also announced a program to build new wind farms - which will, they say, offset the carbon-dioxide emissions for 300 miles of every festival participant's travel to Park City.

The film's producers also arranged to hand out three-packs of Ikea compact fluorescent light bulbs, which are more energy-efficient than incandescent bulbs. "If you don't want to schlep these around," Helfand said, "we recommend you switch out the light bulbs in your hotel room."

Here's the movie's web site, which has more information about ways to fight global warming.
