2,3. The average forest fire size in Canada, the USA and Australia has doubled or even tripled in recent decades4,5. In return, forest fires feed back to climate by modulating land–atmospheric carbon, nitrogen, aerosol, energy and water fluxes6,7,8. However...
Levels of fire activity and severity that are unprecedented in the instrumental record have recently been observed in forested regions around the world. Using a large sample of daily fire events and hourly climate data, here we show that fire activity in
2008). In Europe, human activities including negligence and arson cause more than 95 % of European forest fires (Ganteaume et al. 2012; San-Miguel-Ayanz et al. 2012). At the same time, overall trends are closely linked to weather conditions (Rogelj et al. 2012), and climatic, socio-...
Therefore, estimates of current trends in FFR variability, based on the history of variations in the characteristics of such fires, may contain significant errors. One way to improve the accuracy of such estimates is to include information on FFR variability from other, independent sources in their...
Western forests in the United States are facing multiple threats that have the potential to permanently alter forest composition and structure. In particular, wildfire can either have beneficial or adverse effects on overall forest health and resilience.
However, not all trends are positive. While forests in most states continue to be carbon sinks, forests in some Rocky Mountain states have recently become carbon sources due to the effects of drought, insect and disease epidemics, and forest fires. ...
Background: Landscape fires in South America have considerable impacts on ecosystems, air quality and the climate system. We examined long-term trends and interannual variability of forest, savanna and agricultural fires for the continent during 2001–2012 using multiple satellite-derived fire products....
There was variability within the burned forests, and each forest included burned patches that experienced high severity fires as well as patches with low severity fires. Prior to the fires, both forests were dominated by larch and interspersed with a small proportion of birch. We performed ...
Forest fires are key ecosystem modifiers affecting the biological, chemical, and physical attributes of forest soils. The extent of soil disturbance by fir
which caused the conversion of small patches into large patches and reduced forest fragmentation. In contrast, more frequent fires, caused by climate change in Canada, Far East Russia, the Brazilian Amazon, tropical Africa and coastal Australia (Supplementary Fig.5) have resulted in remarkable forest...
