“Do the Math” PLUS!, a multi-faceted evening to benefit for the global movement 350.org and 350Maine.org, is set for Monday, Aug. 26, beginning 7 p.m. at the Strand Theatre, 345 Main St. Admission is free, with donations welcome to benefit the burgeoning planetary action movement founded in New England and now organized in 188 countries.

With Gulf of Maine water temperatures rising, ocean acidification, new invasive species from the south and the real and present dangers of sea level rise, Maine's coast is on the front lines of climate change.

“Global warming is scary, like solo ocean sailing. First, you've got to know you're running into danger. Then you get out of there as fast as you can on a reciprocal course,” said event organizer Judith Lawson, former solo ocean racer and veteran instructor for Hurricane Island Outward Bound School.

The evening will open with “Do the Math,” a documentary that explains the scientific understanding of climate change with three numbers: 2 degees C, the most warming Earth can handle (we already have 1 degree); 565 gigatons, the amount of carbon emissions that would cause two degrees of warming; and 2,765 gigatons, the amount of carbon that companies plan to burn. It will be followed by a video talk by Bill McKibben recognizing Maine climate activist, North Haven farmer and Congresswoman Chellie Pingree, among others.

A half-hour intermission for an ice cream social and conversation will follow, leading to the PLUS! of the evening’s equation. Musicians David Dodson, Dave Mallett and John and Rachel

Nicholas will offer songs to rouse the spirit and raise the roof. Dodson is known for sparkling wit and pungent social comment. The Nicholas duo, fresh from a spectacular turn at the Sweet Chariot Music Festival, will open with their original anthem. Mallett’s last Strand appearance, a concert in April, was sold out.

Mini TED-style talks will weave between songs. Committed speakers include 9-year-old Thor Gabrielsen, a fourth grade student at Camden-Rockport Elementary School, on the future he foresees for his generation; marine and global climate movement artist George Jennings, speaking as the voice of artists; Nobleboro native Chloe Maxmin, a Harvard junior and 350.org Fellow; an island farmer; and a lobster fisherman.

350Maine.org will have information throughout the evening for people motivated to join local and statewide actions during the remaining Summerheat strategy and upcoming fall actions.

“Do the Math” PLUS! is open to the public by donation. For more information, visit rocklandstrand.com/event/do-math-film-music-event or 350maine.org.
