Inferring wildfire intensity from quartz luminescence
On 8 June 2020, the Mangum Fire ignited 16 miles north of the North Rim of Grand Canyon National Park. By the time it was mostly contained, about a month later, the fire had burned over 70,000 acres of land......»»
Additional nutrients intensify dead zones in oceans, researchers find
As more and more nutrients from land and air enter the world's oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that Ph.D. student Zoë van Kemenade, an organic geochemist at NIOZ, draws from.....»»
New study reveals unintended consequences of fire suppression
The escalation of extreme wildfires globally has prompted a critical examination of wildfire management strategies. A new study from the University of Montana reveals how fire suppression ensures that wildfires will burn under extreme conditions at h.....»»
Research reveals global wildfire risk trends in wildland–urban interface areas
Wildfires present complex socio-economic and ecological challenges, as they devastate vegetation, endanger communities, and cause extensive environmental, wildlife, and human health impacts. These consequences include severe air pollution and soaring.....»»
CERN measures coupled resonance structure that may cause particle loss in accelerators for the first time
Whether in listening to music or pushing a swing in the playground, we are all familiar with resonances and how they amplify an effect—a sound or a movement, for example. However, in high-intensity circular particle accelerators, resonances can be.....»»
Unlocking the climate secrets of North China with ancient tree rings
A study published in the Journal of Geographical Sciences reveals a novel method for reconstructing historical warm season temperatures in North China. Utilizing the blue intensity (BI) of tree rings of Picea meyeri, researchers have developed a 281-.....»»
Gravity waves caused by complex terrain over the Tibetan Plateau can enhance the intensity of spring rainfall
The springtime persistent rainfall is the major rainy period before the onset of summer monsoon in East Asia. For example, it accounts for about 35% of the annual precipitation in South China, which brings plentiful water for agricultural and industr.....»»
Harnessing the mechanisms of fungal bioluminescence to confer autonomous luminescence in plant and animal cells
In a striking new study published in Science Advances, a team of synthetic biologists led by Karen Sarkisyan at the MRC Laboratory of Medical Sciences, have reported the discovery of multiple plant enzymes—hispidin synthases—that can perform the.....»»
Global warming may be behind an increase in the frequency and intensity of cold spells
Global warming caused by increased concentrations of greenhouse gases is already affecting our lives. Scorching summers, more intense heat waves, longer drought periods, more extended floods, and wilder wildfires are consequences linked to this warmi.....»»
Rain offers slight reprieve from largest wildfire in history of Texas
Rainfall offered some reprieve from the largest wildfire in the history of Texas, officials said Friday, though dry, gusty conditions were expected to return this weekend for a blaze that has killed two people and scorched a million acres......»»
Winds threaten to fuel huge Texas wildfire as blizzard hits California
Gusty weekend winds were threatening to worsen a million-acre wildfire that has already killed two people in the southern US, as a monster blizzard engulfed California's mountains Friday......»»
Texas battling largest wildfire in its history
Texas emergency crews were struggling Thursday to contain the largest wildfire in the US state's history, with the blaze leaving at least one person dead and scorching a million acres as it raged out of control......»»
Scientists simulate Lahaina Fire to improve prediction of wildland-urban fires
Scientists have successfully applied a pair of advanced computer models to simulate last year's wildfire that devastated the Hawaiian town of Lahaina. The development could lay the groundwork for more detailed predictions of wildfires that advance in.....»»
Forest Service warns of budget cuts ahead of a risky wildfire season—what does that mean for safety?
A wet winter and spring followed by a hot, dry summer can be a dangerous combination in the Western U.S. The rain fuels bountiful vegetation growth, and when summer heat dries out that vegetation, it can leave grasses and shrubs ready to burn......»»
Scientists map the largest magnetic fields in galaxy clusters using synchrotron intensity gradient
In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the efficiency of turbulent dynamo processes in the amplificat.....»»
Temperatures are rising, but soil is getting wetter—why?
Soil moisture can determine how quickly a wildfire spreads, how fast a hill turns into a mudslide, and perhaps most importantly, how productive our food systems are. As temperatures rise due to human-caused climate change, some researchers are concer.....»»
Back from COP28, California climate leaders talk health impacts of warming
Wildfire smoke. Drought. Brutal heat. Floods. As Californians increasingly feel the health effects of climate change, state leaders are adopting sweeping policies they hope will fend off the worst impacts—and be replicated by other countries......»»
Chile"s biggest botanical garden like "smoker"s lung" after wildfire
Once a lush oasis bursting with native and exotic plants, Chile's biggest botanical garden has been left grayed and charred after a wildfire blazed through last week, also killing a nursery manager and members of her family......»»
Secondary eyewall formation in upper- and lower-layer vertical wind shear simulated in idealized tropical cyclones
About 80% of intense tropical cyclones (TCs) possess concentric eyewalls—namely, the primary and secondary eyewalls. The intensity of the TC can vary considerably during secondary eyewall formation (SEF) and eyewall replacement, posing a great chal.....»»
Chile mourns 122 killed in wildfire inferno, searches for missing
Chile began two days of national mourning Monday for at least 122 victims of a raging wildfire, as the search continued for the missing and survivors picked through the scorched remains of their lives......»»
Extreme heat, wildfire smoke harm low-income and nonwhite communities the most, study finds
Extreme heat and wildfire smoke are independently harmful to the human body, but together their impact on cardiovascular and respiratory systems is more dangerous and affects some communities more than others......»»
