PubTalk 10/2015 — Fire-climate Relationships in the Sierra Nevada
Surprises relevant to future fire regime forecasts
by Jon E. Keeley, USGS Research Scientist
- Historical variation in annual fire activity is tied to climate only in the montane forests.
- Fires are largely insensitive to winter temperatures but significantly affected by spring and summer temperatures.
- Future impacts of global warming on fire activity are largely dependent on the seasonal patterns of warming.
- Lower elevation foothill shrublands and savannahs are not strongly affected by high temperatures in any season.
