MUNICH — Former US Secretary of State John Kerry said Saturday that he’s “ashamed” Vice President Mike Pence didn’t mention climate change while speaking at the Munich Security Conference.

‘‘I’m ashamed that our vice president of the United States stood up here at a security conference and never even mentioned the word ‘climate change,’ ” Kerry said.

“I wish there was a way to hold the president of the United States accountable for the loss of life that is going to take place every day, for the displacement of people, for the trillions of dollars we will have to wind up spending because we’re not getting the job done.’’
