The US Geological Survey (USGS) revealed hundreds of wildfires have been repeatedly reported across southern Alaska. The Alaska Interagency Coordination Center tracked 290 fires in Alaska on July 25, with some 'very large' fires spread across southern Alaska.

The 2015 Alaska fire season already has been declared to be the third-largest season since reliable records began in 1950. These wildfires have burned more than 4.75 million acres.

It is said that the amount of land burned is more than double the size of Yellowstone National Park and larger than the state of New Jersey, which consists of only 4.492 million acres.

USGS stated they have found no clue that could show a direct relationship between climate change and fire, but researchers have found strong correlations between warm June temperatures and large fire years.

Hot, dry spring conditions, however, are not the only causes of wildfires because there is a need of something to create spark and actually start the fire. Lightning starts about 35 % of the fires in Alaska but account for 90 % of the total area burned.

Wildfires can bring a huge change in wildlife habitat, such as by destroying slow-growing lichens in black spruce forests, an important winter food source for caribou.

Alaska temperature has already warmed by more than three degrees in the past half-century, much more than the continental United States said experts.

The consequences of the rising temperature included an annual loss of 75 billion metric tons of ice from its iconic glaciers and the destabilization of permafrost, the frozen ground that underlies 80 % of the state and whose thaw can undermine buildings, roads and infrastructure.
