Wildfires have become more frequent and severe across the U.S. and globally. Since the 1980s, the area burned by wildfires has increased, peaking in spring and summer. The primary driver is climate change, which extends fire seasons, raises temperatures and intensifies droughts. These conditions, along with wind, humidity and temperature shifts, contribute to unpredictable and fast-spreading fires.

Exposure to wildfire smoke might elicit an inflammatory response, potentially leading to reduced cattle performance.
