Democratic presidential candidates discussed climate change at length on the debate stage Wednesday night, addressing energy sources ranging from natural gas to lithium batteries.

White House hopefuls fielded questions on the topic for 15 minutes, dwarfing the amount of time devoted to environmental issues at earlier debates.

“You got to have lithium, you got to have copper for renewable energy. How do you do that?” moderator Jon Ralston asked her, referring to minerals needed to make batteries.

“If we need to make exceptions because there are specific minerals that we've got to have access to, then we would locate those. And we do it not in a way that is just about the profits of giant industries, but in a way that is sustainable for the environment. We cannot continue to let our public lands be used for profits by those who don't care about our environment,” Warren replied.

“We're not going to be able to pass this unless we bring people with us,” Klobuchar said, referencing the numerous climate plans from candidates.

Warren, however, accused Klobuchar of “thinking smaller,” arguing that anti-corruption measures and ending the filibuster would also be needed to battle climate change.

“If you’re not willing to roll back the filibuster, then you're giving the fossil fuel industry veto over all that we work on,” Warren said.

“Let's be real about the deadline. It's not 2050, it's not 2040, it’s not 2030. It’s 2020, because if we don't elect a president who actually believes in climate science now we will never meet any of the other scientific or policy deadlines we need to,” he said.

The extended focus on climate change during the debate comes after environmental groups have repeatedly argued for a climate-themed debate after the topic was given short shrift in earlier debates.
