WASHINGTON -- CNN announced the candidate lineup and other details Tuesday for its September 4 climate town hall.

Ten Democratic 2020 presidential hopefuls will appear back-to-back with CNN journalists to answer questions from a studio audience. It appears CNN has allotted each candidate roughly 40 minutes, and each such segment will include a CNN anchor interviewing a candidate. In addition, CNN has announced that its chief climate correspondent will take part in the questioning.

The live cable television event is slated to last seven hours.

It comes amid growing national and international concern about wildfires burning in the Amazon rainforest in Brazil -- and after President Donald Trump skipped a session of the G-7 meeting focused on climate, saying that his first priority is to maintain America's wealth, not trade away that prosperity for climate initiatives that he described as amounting to "dreams and windmills."

Julián Castro, former HUD secretary, will start the event at 5 p.m.. ET., followed by entrepreneur Andrew Yang at 5:40 p.m.

At its summer meeting last week, the Democratic National Committee faced criticism as its members voted 222-137 against allowing Democratic presidential candidates to participate in a third-party debate focused solely on climate change.

A DNC debate would allow candidates to debate one another as opposed to appearing on stage separately as will be the case with CNN's climate town hall.

To participate in the CNN event candidates were required to reach 2% in at least four Democratic National Committee-approved polls conducted between June 28 and Aug. 21.

Washington Gov. Jay Inslee, the self-styled climate change candidate in the Democratic primary field, dropped out of the race last week after failing to gain momentum. He did not qualify for the CNN town hall, an idea that he had championed.

MSNBC, Georgetown University and Our Daily Planet will host another event from September 19-20, open to all declared candidates, called the “Climate Forum 2020.”
