Mr. Steyer then took a shot at Mr. Buttigieg, saying the South Bend mayor hasn’t put sufficient emphasis on climate change in his platform — the first criticism of Mr. Buttigieg from any candidate in tonight’s debate.“I would call on Mayor Buttigieg to prioritize this higher because the people in his generation understand that this is a crisis that we have to go on right now, but it’s also the greatest opportunity to rebuild and reinvent America,” he said.Mr. Buttigieg did not strike back at Mr. Steyer, instead lumping all of the career politicians onstage together in saying they have done nothing to address climate change.“I’ve seen politicians in Washington say the right thing on climate change as long as I’ve been alive,” he said.Mr. Biden was asked if he was willing to risk moving some jobs from the natural gas and oil industries to address climate change.“The answer is yes,” he said, “The answer is yes, because the opportunity, the opportunity for those workers to transition to high paying jobs, as Tom said, is real.”
