As the narrative of the Southern California wildfires has shifted to identifying the causes behind what could prove to be the most expensive natural disaster in U.S. history, a common refrain has emerged on social media that seeks to dismiss the role scientists say climate change played.

Wildfires fueled by strong Santa Ana winds have devastated Southern California, destroying thousands of homes and causing 27 deaths. The fires, affecting urban areas and the Olympic preparation, are worsened by climate change and urban expansion.

The National Weather Service offices across Southern California are warning residents of an increase in weather conditions that are conducive to rapid fire growth. Meteorologists are most concerned about conditions from Monday afternoon through Wednesday morning when winds will be at their peak and relative humidity will be low.
