CNN’s chief climate correspondent said Wednesday morning that the issue is a top concern for Democratic and independent voters, arguing that the network “could do a town hall a day on this and it wouldn’t be enough to cover” the topic.

“Seven hours on the climate crisis. So just take us behind the scenes. Why did CNN decide to do one topic with this?” “New Day” anchor Alisyn Camerota asked Bill Weir during an interview.

The DNC [Democratic National Committee] didn’t go for that for whatever reason. And so we thought: ‘Why don’t make it happen?’

“So we’re doing … town halls just focused on this,” he continued. “And look, I’m biased. I think we could do a town hall a day on this and it wouldn’t be enough to cover it because it’s everything. It’s everything in our lives, from energy to politics to geopolitics to psychology to history.”

Starting late Wednesday, 10 Democratic candidates will be given 40 minutes to address questions from CNN moderators and audience members in New York.

Anchors Wolf Blitzer, Erin Burnett, Anderson Cooper, Chris Cuomo and Don Lemon will each moderate appearances from two candidates each through the evening, along with Weir.

Former Housing and Urban Development Secretary Julián Castro will be the first candidate featured at 5 p.m. The event will wrap up with Sen. Cory Booker’s (D-N.J.) appearance at 11:20 p.m.

Other candidates who will be participating include tech entrepreneur Andrew Yang, Sen. Kamala Harris (D-Calif.), Sen. Amy Klobuchar (D-Minn.), former Vice President Joe Biden, Sen. Bernie Sanders (I-Vt.), Sen. Elizabeth Warren (D-Mass.), South Bend, Ind., Mayor Pete Buttigieg (D) and former Rep. Beto O’Rourke (D-Texas).

The town hall comes weeks after the DNC’s decision not to host a climate-focused debate.

The committee voted down the proposal last month in a 17-8 vote.
