A coalition of Lawrence environment, art and church groups will start a conversation about climate change this weekend with a series of events designed to reflect on the environment.

The series of events will kick off Saturday, Sept. 20, with a “pray-in and teach-in” regarding climate change, during which the coalition invites the public to stop by Plymouth Congregational Church, 925 Vermont St., between 9 a.m. and 1 p.m. to take part in open discussion groups about climate change.

The Rev. Thad Holcombe, of Ecumenical Campus Ministries, said in a news release that “climate change” refers to the process of global warming.

“We refer to ‘climate change’ here as the general warming of the planet,” Holcombe said, “attributed largely to the increased levels of atmospheric carbon dioxide produced by using fossil fuels.”

On Sunday, Sept. 21, the coalition will be host a party from noon to 3 p.m. on the west side of South Park for the public to come together and create art, signs and climate sign-poles for a celebration march around the park at 2:30 p.m.

The march will be in solidarity with “The People’s Climate March” in New York City on that day, during which environmental advocates will “flood the streets” and demand a cleaner, better world, the news release said.

Snacks and art materials will be provided at the event. The coalition invites attendees to bring art materials including markers and cardboard to help with signage.

In October, the coalition will sponsor three speeches about climate change at the Jewish Community Center, 917 Highland Drive. Topics will include the science of climate change, the impact of climate change in Douglas County and steps to address the phenomenon. Dates have yet to be determined for the speeches, the news release said.
