| Background/Question/Methods:
Wildfires in the western U.S. are generally thought to have increased since the 1980s. Many factors have contributed to this increase such as fire suppression, livestock grazing, and urban sprawl. Fires have also been associated with variations in sea surface temperatures and described by indices such as El Niño Southern Oscillation (ENSO), the Pacific Decadal Oscillation (PDO), and the Atlantic Multidecadal Oscillation (AMO). Recent analyses have also shown that we may have entered a new fire regime starting with a climate shift in 1998 and are currently entering years of combined long-term warm AMO phase with cool ENSO and PDO phases usually associated with increased drought-induced fires in the... |
