Wildfires along Colorado’s Front Range, long assumed to be intensifying, may not be when understood in historical context before 20th-century firefighting, a new study finds.
The findings could complicate the analysis of whether thick forests should be thinned.
University of Colorado researchers, led by fire ecologist and geography professor Tom Veblen, analyzed 8,000 tree-ring samples, starting in 1996, and concluded that severe fires have been an inherent part of mountain ecosystems.
The Army general and ex-CIA chief who led the 2007 U.S. surge to stabilize Iraq praised President Barack Obama’s stepped-up efforts against Islamic State fighters who now have torn that country apart.
But far more difficult than defeating the Islamic State, Gen. David Petraeus said Thursday night in a 9/11 remembrance talk, will be dealing with friction between Shia, Sunni and Kurdish factions afterwards. And neighboring Iran is trying to increase its influence.
Iraqis and their new prime minister Haider al-Abadi “can and should do the reconciliation this time,” Petraeus said, calling Iraqi security forces capable if free from political medding.
The main evergreen and aspen tree species making up Rocky Mountain forests are dwindling and likely will die out dramatically by 2060, according to a report by science advocacy groups.
It’s not clear what will replace them.
The Union of Concerned Scientists and Rocky Mountain Climate Organization report, unveiled Wednesday, draws on U.S. Forest Service data documenting tree deaths and projecting future growth based on climate.
