A long crack in the Larsen C ice shelf in Antarctica grew 11 miles last week, leaving only 8 miles until the 2,000 square mile iceberg is set free into the Southern Ocean."There appears to be very little to prevent the iceberg from breaking away completely," according to Project MIDAS researchers

Why it matters: The iceberg breaking off from the ice shelf will not raise the sea level itself, since the ice is already floating. But as the ice shelves thin, glaciers flow quicker into the sea, which could then cause sea levels to rise.

Keep in mind: Larsen C ice shelf has far less ice beneath it than other ice shelves that are losing mass, the Washington Post points out.

Big picture: Another global warming effect resurfaces just as Trump makes his decision on whether to stay in or leave the Paris Climate Agreement today.

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning 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."

NASA confirms water exists on sunny parts of the Moon


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, a Pence aide confirmed to CNN and Politico on Monday. On Sunday, Senate Democrats claimed that his presence after possible exposure to the coronavirus would be a "violation of common decency."

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.
