A new study examines the history of wildfires along the Colorado Front Range.
Historic wildfires in the pre-suppression era burned just as intensely, scientists say
FRISCO — New research challenges the conventional wisdom that wildfires along the Colorado Front Range have become more severe.
A detailed assessment of fire history across more 1 million acres of forest suggests that only 16 percent of the area showed a shift from historically low-severity fires to severe, potential crown fires that can jump from treetop to treetop.
Even in the days before fire suppression, fires along the Front Range were often destructive, killing many mature trees in the burn areas, the study concluded. Continue reading

Study projects 200 percent increase in burned areas by 2090 without mitigation and adaptation
FRISCO —The American West isn’t alone in facing an increased wildfire threat. Global warming is expected to result in a sharp increase in European forest fires during the coming decades. By 2090, areas burned by fires could increase by as much as 200 percent, according to a new study published in the journal Regional Environmental Change.
Warmer temperatures and longer droughts will combine to fuel forest fire conditions in areas that are already susceptible, particularly the Mediterranean region, the researchers said, suggesting that better forest management, including preventive fires, could keep the increase to less than 50 percent.

The far West and northern Great Basin are especially prone to wildfires this summer.
Potential for big fires still a concern in California
By Bob Berwyn
FRISCO — For the first time in 10 years, the acreage burned by wildfires was less than 1 million acres as of the beginning of July. With extreme drought and high fire danger in parts of the far West, that could change quickly, but for now, both the number of fires and the acreage affected is well below average for the season, according to the National Interagency Fire Center.
To-date, 26,684 fires have burned across about 909,000 acres, less than half he average 2.5 million acres for this time of year. By comparison, wildfires had already burned across more than 1.7 million acres last year at this time. In 2011 that number was at 4.8 million acres. Continue reading

From flood to flames: Western Colorado under Red Flag warning; wildfire danger highest in far west and Southwest

FRISCO — It doesn’t take long to go from floods to fire in Colorado. Even with mountain streams still running high with runoff, weather experts say the fire danger is on the rise as June turns warm and windy. About a third of the state (mostly western Colorado) is under a Red Flag warning going into the weekend, with the National Weather Service warning that warm temps, low humidity and gusty winds will combine to raise the risk of wildfires.
Overall, the fire season outlook for Colorado is not as critical as the past few years, according to the National Interagency Fire Center, which is emphasizing the current fire danger in the far west and the Southwest, including big parts of Arizona and southwestern New Mexico. Continue reading

Numerous Colorado projects delayed as feds juggle budgets in era of monster wildfires
By Bob Berwyn
FRISCO — U.S. Forest Service officials said they’ve had to defer reviews of ski area projects, delay trail improvements and forest restoration work because of the high cost of fighting wildfires. This year, the agency projects a $470 million gap that ripples through the entire Forest Service budget.
More than a dozen important projects in Colorado were on the hit list, according to a new report released this week by the Department of Agriculture. Some of the projects were canceled altogether because their funding has been diverted to fighting wildfires. Continue reading

Areas classified as “probable melt” (light pink) correspond to sites where at least one satellite detected surface melting. Areas classified as “melt” (dark pink) correspond to sites where two or three satellites detected melting.
Widespread surface melting become annual event by the end of this century
FRISCO — Widespread melting on the surface of the Greenland ice sheet was likely caused by a combination of warm temperatures and major depositions of soot and ash from wildfires in the western U.S. and Siberia. The ice sheet last saw a similar melting event in 1889, Dartmouth University scientists concluded in new research published this week in Nature.
“The widespread melting of the Greenland ice sheet required the combination of both of these effects — lowered snow albedo from ash and unusually warm temperatures — to push the ice sheet over the threshold,” said Kaitlin Keegan, the study’s lead author and a Dartmouth doctoral student. “With both the frequency of forest fires and warmer temperatures predicted to increase with climate change, widespread melt events are likely to happen much more frequently in the future.” Continue reading

Firefighter start containment, investigate cause

SILVERTHORNE – Summit County firefighters worked quickly into Monday evening to quash a small wildfire on a private ranch in the Lower Blue Valley.No people or structures were threatened by the five-acre blaze, which was burning in shrubs and dead-standing aspens on a hillside on the Mount Powell Ranch about 10 miles north of Silverthorne along Colorado 9.
More than 30 firefighters and other personnel responded from as far as Copper Mountain, along with law enforcement and state transportation workers, according to Lake Dillon Fire-Rescue spokesman Steve Lipsher. The cause of the fire is still under investigation, Lipsher said.
The fire in the still-damp northern mountains came as much of southern Colorado was under a red flag fire danger warning. The south-central plains are also facing critical fire danger, with persistent drought and the spring windy season at hand.
“Even though it’s early in the season, we take an all-hands-on-deck approach,” said Summit County Sheriff John Minor. “We aren’t taking any chances.”
The fire was reported about 4:15 p.m., and by 7 p.m. firefighters had it about 20 percent contained and were optimistic going into nightfall that they would keep it at its current size. Light winds allowed firefighters to work on containment, but they faced some hazards such as potential falling trees and occasional torching of trees amid the single-digit relative humidity.
Although early in the season, the blaze at about 8,100 feet was not unprecedented for the area at this time of year.
“Fire season is here,” said Lake Dillon Fire Chief Dave Parmley. “We all need to begin that mindset of preparation and awareness, and don’t let the heavy snow of this past winter mislead you into thinking it’s going to be an uneventful summer when it comes to wildfire.”
