As of September 2nd, 2015, over 8.2 million acres in
the United States had burned from this year’s wildfires. That puts the
nation on pace to set a record for number of acres burned. This year’s
total could exceed the record setting year of 2006, when over 9.8
million acres were charred by wildfires. In the 55 years that records
have been kept, all six years that exceeded 8 million acres burned, have been in the 21st century.
On September 2nd, there were 56 active large wildfires
burning in the United States. All 56 were in the American West, with
the three states of Idaho, Montana and Washington accounting for 45 of
the fires. The 8.2 million acres already burned is more than fifty
percent higher than the decade annual average. With more fire season
still ahead, climate change may be making major fires more frequent and
more devastating than ever before. A rough fire season may become the
“new normal”.
The fact that the six worst fire years have all
occurred in the 21st century suggests that climate change is a
significant factor. The Union of Concerned Scientists outline the problem as follows:
Higher spring and summer temperatures and earlier spring snow-melt typically cause soils to be drier for longer, increasing the likelihood of drought and a longer wildfire season, particularly in the Western United States.These hot, dry conditions also increase the likelihood that, once wildfires are started by lightning strikes or human error, they will be more intense and long-burning.
The increased size, intensity and duration of wildfires has put a major budget strain on the U.S. Forest Service. In 2015, they have spent over 50 percent of their budget on preparing for and fighting wildfires.
Twenty years ago, in 1995, just 16 percent of the Forest Service budget
was spent on firefighting. The Forest Service projects that by 2025, a full 2/3rds of their budget will be consumed by fire fighting efforts.
People in coastal areas like Florida and Louisiana
should be concerned about climate change because warming oceans and
rising sea levels can increase the dangers of severe hurricanes and of
coastal flooding. However, the risks posed by human-caused climate
change are not limited to people living at sea level.
The
threat of more and larger wildfires is something that poses a greater
danger to people in the interior West than in any other part of the
country. If nothing is done to address the environmental consequences of
man-made climate change, large sections of the American West will
ignite every summer. Fires burning out of control will just become part
of the new normal.
