A Democratic U.S. Senate primary debate on climate change, featuring at least incumbent Massachusetts Sen. Ed Markey and labor attorney Shannon Liss-Riordan, is set for Sunday, Nov. 10 at Stonehill College.

U.S. Rep. Joe Kennedy, who entered the race leading in polls, has agreed to participate in a climate debate, but the campaign said Thursday evening that the official date, host and location was to be negotiated between the campaigns. The Boston Globe earlier this year reported that Kennedy was pushing for a climate debate early next year “to ensure maximum voter impact and participation.”

Markey in a Thursday night tweet said he and Liss-Riordan had accepted Stonehill’s invitation to debate on Nov. 10. He highlighted that the CNN/The New York Times debate earlier this month didn’t feature “one question about climate change.”

“That won’t happen in MA,” he wrote.

Liss-Riordan’s campaign confirmed Friday morning that she had agreed to the debate.
