LEWISTON —  A forum on youth homelessness in Maine and a talk by a leading climate change activist will take place a day apart in presentations by the Bates College office that facilitates collaborations between the campus and the greater community.

In recognition of National Runaway Homeless Youth Month, the Harward Center for Community Partnerships will present a youth representative and three specialists from social service agencies in a discussion of strategies for addressing youth homelessness at 7:30 p.m. Thursday, Nov. 7, in the Edmund S. Muskie Archives, 70 Campus Ave.

Phil Aroneanu, co-founder of 350.org, an international movement working to curtail climate change, examines strategies and tactics for that campaign at 4:30 p.m. Friday, Nov. 8, in Room G52 of Pettengill Hall, 4 Andrews Road (Alumni Walk).

Admission for both events is open to the public free. For more information, call 786-6202.

In the Nov. 7 discussion, titled “Invisible Strength: Connecting with Homeless Youth,” panelists will discuss the circumstances of homeless young people across Maine and describe successful strategies for engaging them.

Panelists will include a youth representative; Cindy Carraway-Wilson, director of training for Youth Catalytics, a multi-state agency that serves public organizations supporting young people and families; and two administrators from New Beginnings, founded in 1980 to serve homeless youth and their families: Robert Rowe, executive director, and Sarah Vazquez, education specialist.

The Lewiston-based New Beginnings, which serves more than 700 homeless youth and their families from all over the state each year, and the Harward Center have partnered to organize this panel in recognition of National Runaway Homeless Youth Month.

Aroneanu’s Nov. 8 talk is titled “Building a Mass Movement to Fight Climate Change.” He will discuss how the climate change movement can take on carbon bombs like tar sands oil; the role of fossil fuel divestment in the movement; and strategies being employed to progress rapidly toward a clean energy economy that benefits everybody.

Aroneanu co-founded the national Step It Up campaign in early 2007, and in 2009 joined Bill McKibben, the renowned American environmentalist, in founding 350.org. (The organization’s title refers to the goal for reducing the quantity of atmospheric carbon dioxide, expressed in parts per million, to a sustainable level. According to the organization’s website, the current CO2 level is 392 ppm.)

His talk is made possible by sponsorship from the Harward Center, the Bates-Morse Mountain Conservation Area, the environmental studies program, the Environmental Coalition and the Bates Student Government. Additional funding was provided by Project Pericles and the Christian A. Johnson Endeavor Foundation.
