Two more potent atmospheric river storms are hitting California Saturday through Tuesday. With the ground already saturated, the water has no place to go except to run off, causing deadly flooding.

The big picture: The latest storm is prompting evacuations due to high water, and flood watches are in effect for two-thirds of the state's population.

Believe it or not, average global surface temperatures have actually been relatively cool over the last three years — but that's about to change.

Why it matters: Temperatures are expected to jump this year — and 2024 could set a new global record.

The number of unexplained flying object sightings reported to the Pentagon has risen sharply in the last year, according to a new, unclassified government report.

Why it matters: Unidentified aerial phenomena "continue to represent a hazard to flight safety and pose a possible adversary collection threat," according to the report from the Office of the Director of National Intelligence.
