Global warming a key factor in surge of giant forest blazes

With about 1.5 million acres already scarred by wildfires across the U.S. this year, Agriculture Secretary Tom Vilsack is warning of a long, hot fire season ahead. Following a meeting with regional Forest Service leaders, Vilsack, along with Forest Service Chief Tom Tidwell, said that federal budgets are not keeping pace with the steep increase in fires.
Vilsack said 2015 was the most expensive fire season in the department’s history, costing more than $2.6 billion on fire alone.
“The 2016 wildfire season is off to a worrisome start. Southern California, the Great Basin in Nevada, portions of the southwest, and even Florida and Hawaii are particularly vulnerable this year,” Vilsack said. The sustained California drought killed more than 40 million trees, which are all potential fuel, and projections for hot summer weather, driven by global warming and a massive El Niño hangover, will likely increase the danger even more, he added.

Alaska, Southwest could see early season forest fires
April precipitation may have helped dampen the potential for a severe wildfire season in parts of the Rocky Mountain region and in the adjacent Great Plains, according to a new outlook from the interagency Rocky Mountain Area Coordination Center.
The projections is based on various seasonal indicators including precipitation, snowpack average, temperatures, wind, plant and soil moisture, and the timing of green-up. These indices support a below average to near average fire season in 2016.
Flooding, droughts and wildfires all expected to increase
New European climate modeling doesn’t paint a pretty picture for the decades ahead. With global warming, Europe is facing a progressively stronger increase in multiple climate hazards, according to the European Commission’s Joint Research Centre.
A new study University of Leicester researchers maps high-risk wildfire zones in Europe, including cities and tourist areas like Catalonia, Madrid and Valencia — all tabbed as facing potentially catastrophic wildfires. Albania, Bulgaria, Cyprus, France, Italy and Spain could also see more wildfires in the wildland-urban interface zone, according to the study published in the Journal of Environmental Management.

Across the U.S., ozone levels were higher on smoky days than on smoke-free days
Wildfire smoke on its own can trigger health warnings for direct exposure, and new research from Colorado State University suggests that there may be a more widespread impact after they linked smoke with elevated levels of ozone.
Feds spend more than $2.6 billion on fire suppression

For the first time in the era of modern record-keeping, wildfires burned across more than 10 million acres in 2015, mainly due to a series of large fires in Alaska.
According to the U.S. Forest Service, there were more than 50 fires that exceeded 50,000 acres, and 20 fires exceeded more than 100,000 acres. The fires destroyed more than 4,500 homes and other structures and killed 13 wildland firefighters.
The big wildfire season came after two-year lull, when the total wildfire footprint stayed below 5 million acres. For the last years, the average now stands at about 6.6 million acres.
The uptick in fires is no surprise to experts, who have been warning that global warming will result in bigger burns. Alaska, for example, reported its second-warmest year on record in 2015. Since 2000, fire seasons have grown longer, and the frequency, size and severity of wildland fires has increased.
With wildfire costs soaring, agency takes funds from other programs
U.S. Forest Service officials said they were able to step up the pace of restoration projects in 2015 despite facing tough budget challenges during a record wildfire season.
Despite the gains, at least 65 million National Forest System acres are still in need of restoration, agency leaders said, explaining that the rising cost of wildfire suppression has taken funding away from restoration, watershed and wildlife programs, limiting the Forest Service’s ability to do the work that would prevent fires in the first place.
