2004 Alaska fire season

The 2004 Alaska fire season was the worst on record in terms of area burned by wildfires in the U.S. state of Alaska. Though there were fewer fires than in 1989 when almost 1,000 were recorded, more than were burned by 701 fires. The largest of these fires was the Taylor Complex Fire. This fire consumed over and was the deemed to be the largest fire in the United States from 1997 to 2007.〔 Out of all 701 fires, 426 fires were started by humans and 215 by lightning.〔
== Impacts on Climate Change & Landscape ==
Alaska has a climate that of the boreal zone, more commonly known as the Taiga. The boreal zone, across the globe, makes up more than 25% of global forests, and when wildfires occur it is a top leader in carbon emissions.〔 Approximately 12% of the world's carbon is stored in top layer soil and this part is the first to burn in any wildfire. These emissions have some of the greatest impacts on natural carbon balance, and Alaska gives its fair contribution.〔 Typically Alaskan forest fires make up 41% of the United States total carbon emissions, but more recently with warming conditions and more wildfire occurrences these figures have gone all the way to 89%.〔 Landscape is also changing with regards to wildfires as less canopy is provided after an occurrence, hence soil temperatures may rise and be inhabitable by certain species.〔 When soil temperatures rise permafrost is revealed and begins to melt away.〔 This then leads to Landslides and Erosion.〔
