Published Low-intensity fires reduce wildfire risk by 60%
(via sciencedaily.com) Original source High-intensity, often catastrophic, wildfires have become increasingly frequent across the Western U.S. Researchers quantified the value of managed low-intensity burning to dramatically reduce the risk of such fires for years at a time.
Published Lightning identified as the leading cause of wildfires in boreal forests, threatening carbon storage
(via sciencedaily.com) Original source Most wildfires in boreal forests, such as those in Canada, are caused by lightning strikes, according to a study aimed at attributing fire ignition sources globally.
Published Southern Alaska's national forests key to meeting climate, conservation goals
(via sciencedaily.com) Original source Analyses of U.S. national forests shows that increased protections for two Alaskan forests is a key to meeting climate and biodiversity goals.
Published The kids aren't alright: Saplings reveal how changing climate may undermine forests
(via sciencedaily.com) Original source Researchers studied how young trees respond to a hotter, drier climate. Their findings can help shape forest management policy and our understanding of how landscapes will change.
Published The importance of the Earth's atmosphere in creating the large storms that affect satellite communications
(via sciencedaily.com) Original source Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.
Published Solar farms in space are possible
(via sciencedaily.com) Original source It's viable to produce low-cost, lightweight solar panels that can generate energy in space, according to new research.
Published New study shows surprising effects of fire in North America's boreal forests
(via sciencedaily.com) Original source Using satellite images, researchers found that fires in North America's boreal forest may be changing the environment in ways that researchers didn't previously anticipate.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published Wildfires threaten environmental gains in climate-crucial Amazon
(via sciencedaily.com) Original source Despite steps toward decreasing deforestation, uncontrolled wildfires are threatening environmental gains in Brazilian Amazonia, one of the world's most critical carbon sinks and a region of high biological and cultural diversity.
Published Research shows wildfire smoke may linger in homes long after initial blaze
(via sciencedaily.com) Original source Newly published research on indoor air quality shows wildfire smoke may linger in homes long after the initial blaze has been put out or winds have shifted. The findings show that wildfire smoke can attach to home surfaces like carpet, drapes or counters -- extending the exposure for those inside and potentially causing health problems even after an initial cleaning activity by air purifiers.
Published Epiphytes, amazing plants like moss and bromeliads found in trees, face growing threats
(via sciencedaily.com) Original source Epiphytes, plants such as orchids and mosses that grow in trees, draw nutrients from the air and create refuge for all sorts of other life forms. They are the foundation of forest canopy ecosystems, but they are facing threats from human and natural disturbances.
Published New study offers improved strategy for social media communications during wildfires
(via sciencedaily.com) Original source New research offers an improved strategy for social media communications during wildfires and contradicting existing crisis communication theory.
Published Researchers identify largest ever solar storm in ancient 14,300-year-old tree rings
(via sciencedaily.com) Original source An international team of scientists have discovered a huge spike in radiocarbon levels 14,300 years ago by analyzing ancient tree-rings found in the French Alps. The radiocarbon spike was caused by a massive solar storm, the biggest ever identified. A similar solar storm today would be catastrophic for modern technological society – potentially wiping out telecommunications and satellite systems, causing massive electricity grid blackouts, and costing us billions. The academics are warning of the importance of understanding such storms to protect our global communications and energy infrastructure for the future.
Published Simultaneous large wildfires will increase in Western U.S.
(via sciencedaily.com) Original source Simultaneous outbreaks of large wildfires will become more frequent in the Western United States this century as the climate warms, putting major strains on efforts to fight fires, according to new research. The most severe wildfire seasons will become at least twice as frequent.
Published Extreme fires and heavy rainfall driving platypuses from their homes
(via sciencedaily.com) Original source Australia's emerging pattern of severe mega bushfires and heavy rainfall may be driving platypuses from their homes, a new study has shown. Analysis of platypus DNA in rivers and creek water samples collected before and after the Black Summer 2019-2020 megafires suggest Australia's beloved semi-aquatic monotremes might be abandoning severely bushfire-affected areas for up to 18 months after a fire, especially if heavy rainfall has followed the fire.
Published Controlled burns help prevent wildfires; Climate change is limiting their use
(via sciencedaily.com) Original source Climate change means the American West will have 17% fewer safe days to light prescribed fires for wildfire management, according to new research. Winter, however, will see a net 4% increase in the number of favorable days. Implementing controlled burns in the West will require changes to policy and the availability of firefighters.
Published Climate and human land use both play roles in Pacific island wildfires past and present
(via sciencedaily.com) Original source It’s long been understood that human settlement contributes to conditions that make Pacific Islands more susceptible to wildfires, such as the devastating Aug. 8 event that destroyed the Maui community of Lahaina. But a new study from fire scientist shows that climate is an undervalued part of the equation.
Published Scientists reveal what fuels wildfires in Sierra Nevada Mountains
(via sciencedaily.com) Original source Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there's a growing need to know exactly what fuels the blazes after they ignite. Scientists now report that one of the chief fuels of wildfires in California's Sierra Nevada mountains is the decades-old remains of large trees.
Published By air, rain and land: How microbes return after a wildfire
(via sciencedaily.com) Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.
Published Socially vulnerable populations are disproportionately exposed to wildfires in the Western US
(via sciencedaily.com) Original source People experiencing a high degree of social vulnerability are also more exposed to wildfires in Oregon and Washington as wildfire risk increases, a new study shows.
