CNN on Tuesday released new details for what will be a first-of-its-kind 7-hour town hall focused on climate change on Sept. 4.

Why it matters: Climate activists were enraged at the Democratic National Committee last week for voting down a proposed presidential debate centered solely on climate change. While the town hall will not offer the head-to-head format activists have sought, it does offer some platform for an issue that spent much of the 2016 campaign on the back burner. An April CNN poll showed that 96% of Democrats favor taking "aggressive action" to combat the issue.

Details, per CNN (all times are Eastern Time):

  • 5 pm: Former Housing and Urban Development Secretary Julián Castro
  • 5:40 pm: Businessman Andrew Yang
  • 6:20 pm: California Sen. Kamala Harris
  • 7 pm: Minnesota Sen. Amy Klobuchar
  • 8 pm: Former Vice President Joe Biden
  • 8:40 pm: Vermont Sen. Bernie Sanders
  • 9:20 pm: Massachusetts Sen. Elizabeth Warren
  • 10 pm: South Bend, Indiana, Mayor Pete Buttigieg
  • 10:40 pm: Former Rep. Beto O'Rourke
  • 11:20 pm: New Jersey Sen. Cory Booker

Twitter launches warnings on election misinformation and delays

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning them that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Why it matters: Delayed election results are expected across many states that are handling unprecedented amounts of absentee and mailed ballots, which President Trump has baselessly called "very dangerous" and "corrupt."

Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.

Vice President Mike Pence no longer plans to attend the Senate's final confirmation vote for Judge Amy Coney Barrett on Monday, following Senate Democrats' claims that his presence after possible exposure to the coronavirus would be a "violation of common decency," a Pence aide confirmed to CNN and Politico on Monday.

Driving the news: Five of Pence's aides were recently diagnosed with COVID-19, including his chief of staff, who is currently quarantining. Pence has continued his campaign travel despite his possible exposure, which goes against CDC guidelines.
