Extreme conditions helped fuel the fast-moving fires that destroyed thousands of homes. Scientists are working to figure out how climate change played a role in the disaster.

A study by UCLA, published on Jan. 15, showed that 85% of individuals employed as household workers in Los Angeles are Latino. And, among these individuals, 47% are self-employed, making them ineligible for unemployment benefits or formal protections such as paid leave.

An international panel of scientists says with "high confidence" that climate change is worsening Southern California's fire threat.
