Published Wildfire-smoke observations fill gap in estimating soot's role in climate change
(via sciencedaily.com) New research refining the amount of sunlight absorbed by black carbon in smoke from wildfires will help clear up a long-time weak spot in earth system models, enabling more accurate forecasting of global climate change.
Published Cats injured in wildfires at risk of deadly blood clots
(via sciencedaily.com) Cats injured in California wildfires are at risk of forming deadly blood clots, according to new research.
Published California's trees are dying, and might not be coming back
(via sciencedaily.com) The State of California is banking on its forests to help reduce planet-warming carbon dioxide in the atmosphere. But that element of the state's climate-change solution arsenal may be in jeopardy, as new research reports that trees in California's mountain ranges and open spaces are dying from wildfires and other pressures -- and fewer new trees are filling the void.
Published California's Dixie Fire shows impact of legacy effects, prescribed burns
(via sciencedaily.com) The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and low-severity fire treatments had the largest impact on reducing the worst effects of the fire, according to a research team.
Published Study reveals an unprecedented change in Europe's fire regime
(via sciencedaily.com) A study reveals an unprecedented change in the fire regime in Europe which is related to climate change. The affected areas are in Southern, Central and Northern Europe but this historical change in Europe's fire regime is more intense in the Mediterranean area.
Published Climate change will increase chances of wildfire globally -- but humans can still help reduce the risk
(via sciencedaily.com) New research highlights how the risk of wildfire is rising globally due to climate change -- but also, how human actions and policies can play a critical role in regulating regional impacts. The study shows that anthropogenic climate change is a 'push' factor that enhances the risk of wildfires globally.
Published Wildfires may have sparked ecosystem collapse during Earth's worst mass extinction
(via sciencedaily.com) New research reveals that wildfires may have been a key contributor to the total collapse of land ecosystems during Earth's worst mass extinction event over 250 million years ago.
Published Simultaneous extreme weather created dangerous cascades in U.S.
(via sciencedaily.com) Intense heat in the southwestern United States broke records last summer partly because it hit in tandem with an unusually severe drought, finds a new study measuring for the first time how the two extreme weather events dangerously interacted in real time.
Published Insight into past--and future--of Western US wildfires
(via sciencedaily.com) A new study examines the context surrounding the fires and offers insight into the historical role of large, high-severity fires -- and the future of wildfires -- west of the Cascades.
Published Wildfire smoke exposure negatively impacts dairy cow health
(via sciencedaily.com) Increasing frequency and size of wildfires in the United States over the past several decades affect everything from human life and health to air quality, biodiversity, and land use. The US dairy industry is not exempt from these effects. The Western states, where wildfires are especially prevalent, are home to more than two million dairy cows that produce more than 25% of the nation's milk. A new report examines how dairy cattle in the Western United States may be affected by unique air pollutants from wildfire smoke.
Published Earliest record of wildfires provide insights to Earth's past vegetation and oxygen levels
(via sciencedaily.com) Original source While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of Earth's systems without the influence of humans for hundreds of millions of years.
Published New fire shelter prototypes could buy time for wildfire firefighters
(via sciencedaily.com) Original source Temperatures inside new wildfire shelter prototypes remained within survival limits for longer, and the shelters took longer to break open, compared with an industry standard.
Published Major infrared breakthrough could lead to solar power at night
(via sciencedaily.com) Using technology similar to night-vision goggles, researchers have developed a device that can generate electricity from thermal radiation.
Published Modeling Earth's magnetosphere in the laboratory
(via sciencedaily.com) Scientists report a method to study smaller magnetospheres, sometimes just millimeters thick, in the laboratory. The new experimental platform combines the magnetic field of the Large Plasma Device with a fast laser-driven plasma and a current-driven dipole magnet. The LAPD magnetic field provides a model of the solar system's interplanetary magnetic field, while the laser-driven plasma models the solar wind and the dipole magnet provides a model for the Earth's inherent magnetic field. Motorized probes allow system scans in three dimensions by combining data from tens of thousands of laser shots.
Published Researchers discover source of super-fast electron 'rain'
(via sciencedaily.com) Scientists have discovered a new source of super-fast, energetic electrons raining down on Earth's atmosphere, a phenomenon that contributes to the colorful aurora borealis and poses hazards to satellites, spacecraft and astronauts.
Published Ancient ice reveals mysterious solar storm
(via sciencedaily.com) Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events.
Published A lab in the sky: Physics experiment in Earth’s atmosphere could help improve GPS performance
(via sciencedaily.com) The Earth's atmosphere has been used as a 'laboratory' to carry out a physics experiment which could help to improve the performance of GPS.
Published Protecting Earth from space storms
(via sciencedaily.com) A major space weather event could have a catastrophic impact on Earth, disabling communications and electrical systems. Researchers are using the Frontera supercomputer to develop new geomagnetic forecasting methods and improve the Geospace Model used by NOAA for operational purposes. They hope to increase the lead time for space weather events from 30 minutes to 1-3 days, localize space weather forecasts, and provide uncertainty estimates.
Published Solving solar puzzle could help save Earth from planet-wide blackouts
(via sciencedaily.com) Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots. Mathematicians have proposed a new model of the Sun that matches observed data.
Published Unravelling the knotty problem of the Sun's activity
(via sciencedaily.com) A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behavior of active regions and the nature of the solar interior.
