Colorado fire: Is global warming one of the culprits? (+video)

“As the climate warms, moisture and precipitation levels are changing, with wet areas becoming wetter and dry areas becoming drier,” the organization reports. “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.”
To those tasked with preventing and fighting wildfires, climate change has become a major challenge.
“On average, wildfires burn twice as many acres each year as compared to 40 years ago. Last year, the fires were massive in size, coinciding with increased temperatures and early snow melt in the West,” US Forest Service Chief Tom Tidwell told the Senate Energy and Natural Resources Committee in testimony last week. “The largest issue we now face is how to adapt our management to anticipate climate change impacts and to mitigate their potential effects.”
In its report accompanying Mr. Tidwell’s testimony, the Forest Service detailed the increasing costs of fire-fighting.
Costs of fire suppression have increased to consume nearly half of the entire Forest Service budget. In fiscal year 1991, fire activities accounted for about 13 percent of the total agency budget. In fiscal year 2012, it was more than 40 percent. Since fiscal year 2000, the 10-year average cost has risen almost every year – from a little more than $540 million to more than $1 billion in 2010 and beyond.
During the past 10 years, the Forest Service has made fire transfers from non-firefighting accounts to pay for fire suppression costs six times, ranging from a low of $100 million in fiscal year 2007 to a high of $999 million in fiscal year 2002, and totaling approximately $2.7 billion. Of that total, $2.3 billion was repaid but led to disruptions within many Forest Service programs.
In Colorado, meanwhile, the US Department of Agriculture has designated six counties as primary natural disaster areas and six more as contiguous disaster areas due to ongoing severe drought conditions, US Senator Michael Bennet (D) of Colorado announced this week.
“Despite some relief earlier this year, right now we’re seeing how quickly our weather can get hot and dry, creating hazardous fire and drought conditions,” Sen. Bennet said.
