Summer 2004 saw severe forest fires in Alaska and the Yukon Territory that were mostly triggered by lightning strikes. The area burned (>2.7 x 10^6 ha) in the year 2004 was the highest on record to date in Alaska. Pollutant emissions from the fires lead to violation of…

The contribution of wildfire in peatlands outside of boreal and tropical regions to interannual variability of global carbon emissions has been relatively little studied. There are 0.19 to 0.88 million km^2 of localized peat deposits in the temperate zone (30-50 degrees latitude…

We used a new, 100-year, 1 × 1° global fire map and a carbon cycle model (CASA) to provide a yearly gridded estimate of the temporal trend in carbon emissions due to wildfires through the 20th century. 2700–3325 Tg C y−1 burn at the end of the 20th century, compared to 1500–2700…

Thinning of forest stands is frequently used to reduce the risk of catastrophic fire. But thinning requires that the refuse (or slash) be removed from the site, which can be done either by burning it or by mastication and dispersal. Either method has long term consequences to…
