Washington(CNN) CNN on Tuesday announced the candidate lineup for its unprecedented prime-time event focused on the climate crisis.

Ten Democratic presidential hopefuls will appear in New York at back-to-back town halls on Wednesday, September 4, taking audience questions about their climate plans as scientists sound the alarm about global warming.

Along with the candidates, the network also announced the CNN journalists and the approximate appearance times for the presidential hopefuls during the seven-hour, live event.

Former Housing and Urban Development Secretary Julián Castro will be interviewed by CNN's Wolf Blitzer at 5 p.m. ET

Businessman Andrew Yang, who will also be interviewed by Blitzer, will come on at 5:40 p.m.

California Sen. Kamala Harris will be interviewed by CNN's Erin Burnett at 6:20 p.m.

New Jersey Sen. Cory Booker will also be interviewed by Lemon and will come on at 11:20 p.m.

CNN previously announced that Chief Climate Correspondent Bill Weir will join in the questioning throughout the evening.

A CNN poll conducted in late April showed that 96% of Democrats favored taking aggressive action to slow the effects of climate change. And Democratic activists in recent weeks have sought to elevate the issue, urging candidates to make climate change a priority.

The United Nations -- which projects that temperatures will rise to 1.5 degrees Celsius above pre-industrial levels by as early as 2030 -- has warned that governments must take "rapid, far-reaching and unprecedented changes in all aspects of society."

Global warming would have several devastating consequences. It would cause coastal cities to disappear under water, leaving hundreds of millions of people displaced and forced to migrate to dry areas. Some plants and animals would face extinction, and drought would result in lower crop yields.

The latest warning signs of a climate crisis include meteorologists recording July 2019 as the hottest month ever recorded on Earth and Greenland lost 12.5 billion tons of ice to melting on August 2, the largest single-day loss in recorded history.

The town halls will air exclusively on CNN, CNN International, CNN en Español, CNN.com's homepage, across mobile devices via CNN's apps for iOS and Android, via CNNgo apps for Apple TV, Roku, Amazon Fire, Chromecast and Android TV, SiriusXM Channels 116, 454, 795 and the Westwood One Radio Network.

CNN previously announced that the town hall audience will be drawn from Democratic and independent voters and stakeholders interested in the issue and no public tickets will be available.
