At Joshua W. Glotzer, APC, we understand that the pain and
severity of burn fire and explosion injuries can not be overstated.

«We found prescribed
burns really reduced the
severity of the Rim
Fire,» said Alan Taylor, professor
of geography and associate in the Earth and Environmental Systems Institute at Penn State.
«Low
severity burning seems to be very effective at limiting the
severity of subsequent
fires,» said Lucas Harris, a graduate student in geography and lead author on the paper.
«Controlled
burns limited
severity of Rim
Fire.»
Many
fire scientists have tried to get Smokey the Bear to hang up his «prevention» motto in favor
of tools like thinning and prescribed
burns, which can manage the
severity of wildfires while allowing them to play their natural role in certain ecosystems.
In addition, our
fire weather season length metric captures variations in the number
of days each year that
fires are likely to
burn, but it does not account for inter-annual variations in
fire season
severity.
Further work should consider both a lengthening
fire season and an increase in within - season
fire weather
severity as causal mechanisms
of burned area variations.
Worldwide, vegetation
fires are showing a trend toward longer
burning periods, increased
fire severity, larger areas
burned and increased (mostly human caused) frequency — with all
of these factors contributing to more damaging environmental impacts, higher shares
of emissions and increasing socioeconomic costs, including greater threats to human health and security.
As for the
severity of burning, that is one thing that we can «control» fairly well by using prescribed
fire only under the right seasonality (see early summer
burning in e.g. South Africa or Australia), the right local weather conditions, and through the correct methodology / application.
Some large high
severity fires occurred in these areas during the 1950s drought, and subsequent droughts, but the largest total areas
burned in forests were an order
of magnitude smaller than the largest
fires today.
Butsic: There's a growing body
of evidence that prescribed
fires are less harmful to humans than non-managed wildfires, because they
burn at lower
severity, typically.
The frequency and intensity
of forest
fires in the region have been increasing along with rising temperatures.5, 7,13 An average
of around 9.9 million acres (4 million hectares)
of boreal forest
burned annually in Russia from 1975 to 2005 — and that rate more than doubled in the 1990s.15 One
of West Siberia's largest forest
fires on record occurred in 2003, claiming some 47 million acres (20 million hectares)
of land7, 15 and emitting heat - trapping emissions equal to the total cuts in emissions the European Union pledged under the Kyoto Protocol.2, 7,16 Higher temperatures and thawing permafrost are probably contributing to the rising frequency and
severity of forest
fires in West Siberia.5, 7,14
No, the bark beetle outbreaks have little - to - no relationship with trends in area
burned or the ecological
severity of fires.
This sensor has been useful for investigating fuel load type and subsequent effects on emission types,
fire behavior, and post-
fire analysis (e.g., safety, erosion, area
burned,
fire severity or the amount
of environmental change caused the
fire, etc.) and is often analyzed in interagency and federal - academic coordination to improve our understanding
of fire.
The researchers concluded: «The data available to date do not support a general increase in area
burned or in
fire severity for many regions
of the world.
