12 August 2017, New York Times, Portugal Forest Fires Worsen, Fed by Poor Choices and Inaction. When Portugal’s deadliest wildfire killed more than 60 people in June not far from the hamlet where Daniel Muralha lives, it was just the pensioner’s latest brush with death. 2003, Mr. Muralha, 77, narrowly survived a huge forest fire that engulfed his house. In 2015, a fire destroyed his field. And this July, he watched anxiously as fire burned the trees above his property. fires are getting worse and worse, which means this place is going to become a desert,” he said. “I’m too old to move elsewhere, but more people, of course, decide to leave after every fire.” What he describes is an increasingly urgent problem for his country. Hotter, drier summers are setting off more forest fires, which are accelerating a decades-old migration from rural areas, leaving lands untended. That, in turn, helps fuel new and more intense fires that spread and burn even faster. deadly spiral, forestry experts and environmentalists say, has been worsened by political inaction, a history of poor land management and the prioritizing of firefighting over fire prevention, even in the face of more frequent tragedies. But Portugal has become a particularly stark case of what the future may hold if changes to land, climate and economies go mismanaged. The deaths in June provoked a fresh round of soul-searching and spurred an investigation, still continuing, into how and why the wildfire engulfed Pedrógão Grande, about 10 miles from where Mr. Muralha lives, close to Oleiros. Oleiros and its environs are a prime example of the changes to the landscape that have rendered Portugal ever more vulnerable to fire. Read More here

28 July 2017, Climate Central, Wildfire Season Is Scorching the West. The West is ablaze as the summer wildfire season has gotten off to an intense start. More than 37,000 fires have burned more than 5.2 million acres nationally since the beginning of the year, with 47 large fires burning across nine states as of Friday. The relatively early activity is quickly becoming the norm, with rising temperatures making the fire season longer than it used to be. The warming fueled by greenhouse gases is also helping to create more and larger fires as it dries out more vegetation that acts as fuel for fires. This new fire situation means that western states need to be begin to rethink how they prepare for and combat fires, as well as how fire-prone land is developed. Five large fires (those of 1,000 acres or more) are currently raging across California, the largest of which is the Detwiler fire near Yosemite National Park, which has burned more than 80,000 acres since it ignited on July 16. That fire is now 75 percent contained, but it destroyed dozens of buildings, including 63 homes. Oregon has seven large fires burning, while Nevada has six and Idaho five.Montana currently has the most large fires of any state, with 14, including the massive Lodgepole Complex fire (a series of smaller fires that merged into one), which has burned more than 270,000 acres in the eastern portion of the state. That fire is also well-contained, but has burned through tens of thousands of acres of range land, displacing thousands of cattle and burning several structures. An intense drought there has rapidly cured the grasses that have fueled the fires. Scorching temperatures and dry conditions in recent weeks have helped fuel these fires across the region, which have burned 2 million more acres than at this point in last year’s wildfire season.

28 June 2017, Climate Home, Even Boeing-747 tanker jets can’t win our total war on fires. The more effectively we suppress fires, the worse they become. As climate change makes the world more combustible, we need a new approach. In 1910 Ed Pulaski, a US Forest Service ranger, rounded up his men who were fighting a forest fire in dense conifer forests in northern Idaho and forced them, some at gunpoint, to take refuge in an abandoned mine shaft. The Pulaski tunnel (now a tourist site) represents the dramatic historical moment when ad-hoc approaches to controlling wildfire were shown to be utterly inadequate – this heroic failure provided the impetuous for the US Forest Service to declare total war on fire. Nearly all of Pulaski’s men survived the conflagration, one of thousands of fires that burnt across Idaho during an extremely hot and dry summer, an event now known at the ‘Big Burn’. The sheer ferocity, geographic scale and destructive power of the 1910 Idaho fires shifted the focus of the US Forest Service (USFS) from forestry toward fire fighting. This led to the development of networks of fire towers to identify wildland ignitions. They would be extinguished by teams of trained forest fire fighters, many of whom use a combined ax and mattock invented by, and named after, Ed Pulaski.The iconic mascot Smokey Bear was created by the US advertising industry to promote forest fire awareness. The USFS fire fighting policy evolved to a mandated extinguishment of any new forest fire ignition by 10am the following day, with some managers demanding that the fire size was kept below 10 acres. This total war on fire also drove innovation. In the early 1960 the USFS established Fire Lab at Missoula where an aeronautic engineer, redeployed after the defence department project he was working on was cancelled, developed the first mathematical description of fire, creating the foundation for predictive fire behaviour modelling….But there is a very big catch. The US approach is proving to be ecologically and economically unsustainable – especially in an era of increasing fire threat due to climate change.1 Total fire suppression has created the ‘fire suppression paradox’: the more effective suppression is the worse fires become. Fuel that would historically have been burnt by lightning or indigenous people builds up, resulting in catastrophic fires that are uncontainable regardless of the available technology. The fire suppression paradox also has another unintended and counterproductive consequences: communities come to believe flammable landscapes are safe, resulting in increasing urban sprawl into wildlands that are primed to burn. This massively increases the risk of loss of life and property and the inevitable, tragic loss drives further investment into aerial fire fighting. Climate change is turbo-charging this feedback – fire seasons are worsening, fire disasters are becoming more destructive, and hence demands for more investment in aggressive fire fighting are growing worldwide. Collectively this is creating a dangerous and economically and ecologically unsustainable fire-suppression spiral. Read More here
23 February 2017, The Conversation, Australia’s 2016 environment scorecard: rains return but in some cases too late. After several dry years, vegetation across much of Australia received much-needed rains in 2016. But this broad pattern of improvement belies some major environmental damage in parts of the country – particularly in Tasmania, which was scorched by bushfire, the Gulf Coast and Cape York, which missed out on the rains’ return, and on the Great Barrier Reef, which suffered massive coral bleaching. That is the conclusion of our report on Australia’s Environment in 2016, released today. It’s a summary of the state of the nation’s environmental indicators, which we compiled by analysing huge amounts of satellite imagery, ground data, and water and landscape modelling. The report and the accompanying Australia’s Environment Explorer website summarise those data into graphs and plots for 13 environmental indicators. With most data extending back to at least the year 2000, this makes it possible to see how the environment is changing. Read More here
