Wildfires used to 'go to sleep' at night. Climate change is turning them into prime burning hours

Climate Change Impact on Wildfires

A new study published in Science Advances indicates that human-caused climate change is extending the period and duration of wildfire risk across North America, allowing fires to burn at night more frequently. The research highlights that warmer, drier nighttime conditions and increased fire-prone days are making fires harder to control. Experts suggest these changes are stressing ecosystems and increasing overall fire potential.

“Burning time for North American wildfires is going into overtime. Flames are lasting later into the night and starting earlier in the morning because human-caused climate change is extending the hotter and drier conditions that feed fires, a new study found.”
CORROBORATED
Multiple web search results report that human-caused climate change is extending hotter and drier conditions, causing wildfires to burn later into the night and start earlier in the morning. This pattern is reported across different search snippets.

“Since 1975, summers in the contiguous U.S. have seen nighttime lowest temperature warm by 2.6 degrees Fahrenheit (1.4 degrees Celsius), while daytime highest temperatures have gone up 2.2 degrees Fahrenheit (1.2 degrees Celsius), according to the National Oceanic and Atmospheric Administration.”
SINGLE SOURCE
The claim cites specific temperature increases from NOAA. While the evidence confirms NOAA's role in climate data, the specific figures (2.6°F/1.4°C for nighttime lows and 2.2°F/1.2°C for daytime highs since 1975) are only present in the context of the web search results, and no other independent source confirms these exact numbers.
