DoomsdaysCWHuman use of fire has produced an era of uncontrolled burning: Welcome to the <a href="https://kolektiva.social/tags/Pyrocene" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pyrocene</a>by Stephen Pyne, The Conversation, January 22, 2025"<a href="https://kolektiva.social/tags/LosAngeles" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LosAngeles</a> is burning, but it isn't alone. In recent years, fires have blasted through cities in <a href="https://kolektiva.social/tags/Colorado" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Colorado</a>, the southern <a href="https://kolektiva.social/tags/Appalachians" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Appalachians</a> and the island of <a href="https://kolektiva.social/tags/Maui" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Maui</a>, along with <a href="https://kolektiva.social/tags/Canada" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Canada</a>, <a href="https://kolektiva.social/tags/Australia" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Australia</a>, <a href="https://kolektiva.social/tags/Portugal" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Portugal</a> and <a href="https://kolektiva.social/tags/Greece" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Greece</a>. What wasn't burned was smoked in."Is this another case of a future not only dire but strange, without a narrative to join past to present or an analog for what is to come?"I'm a historian of fire, and my reply is that we have both a narrative and an analog. The narrative is the unbroken saga of humanity and fire, a companionship that extends through all our existence as a species. The analog is that humanity's fire practices have become so vast, especially in recent centuries, that we are creating the fire equivalent of an ice age."[...]Welcome to the Pyrocene"Widen the aperture a bit, and we can envision Earth entering a fire age comparable to the ice ages of the Pleistocene, complete with the pyric equivalent of ice sheets, pluvial lakes, periglacial outwash plains, mass extinctions and sea-level changes. It's an epoch in which fire is both prime mover and principal expression."Humanity's firepower underpins the <a href="https://kolektiva.social/tags/Anthropocene" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Anthropocene</a>, which is the outcome not just of <a href="https://kolektiva.social/tags/anthropogenic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#anthropogenic</a> meddling but of a particular kind of meddling, made possible by humans' species monopoly over fire. Even climate history has become a subset of fire history."Fires in living landscapes, fires burning lithic landscapes—the interaction of these two realms of fire has not been much studied. It's been enough of a stretch to fully include human fire practices within traditional ecology. Yet humans—the keystone species for fire on Earth—are merging the two arenas of earthly burning with a give and take that is reshaping the planet in what resembles a slow-motion <a href="https://kolektiva.social/tags/Ragnarok" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Ragnarok</a>."Add up all the effects, direct and indirect: the ice driven off by fire, the areas burning, the biogeographical <a href="https://kolektiva.social/tags/migrations" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#migrations</a> as biotas move to accommodate changed conditions, the collateral impacts with damaged <a href="https://kolektiva.social/tags/watersheds" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#watersheds</a> and <a href="https://kolektiva.social/tags/airsheds" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#airsheds</a>, the unraveling of <a href="https://kolektiva.social/tags/ecosystems" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ecosystems</a>, the pervasive power of <a href="https://kolektiva.social/tags/ClimateChange" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ClimateChange</a>, <a href="https://kolektiva.social/tags/RisingSeaLevels" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RisingSeaLevels</a>, a <a href="https://kolektiva.social/tags/MassExtinction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MassExtinction</a>, the disruption of human life and habitats.

DoomsdaysCWNot just human health! The <a href="https://kolektiva.social/tags/Toxic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Toxic</a> Blend of LA’s Urban <a href="https://kolektiva.social/tags/WildfireSmoke" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WildfireSmoke</a> Will Have Lasting Health Consequences Los Angeles residents are breathing bits of "cars, metal pipes, plastics." By Zoya Teirstein, January 22, 2025“These fires are different from previous quote-unquote ‘wildfires,’ because there are so many structures that burned,” said Yifang Zhu, a professor of environmental health sciences at the University of California, Los Angeles. 'Everything in the households got burned — cars, metal pipes, plastics.'"<a href="https://kolektiva.social/tags/Wildfiresmoke" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Wildfiresmoke</a> is toxic. Burning trees and shrubs produce very fine <a href="https://kolektiva.social/tags/particulatematter" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#particulatematter</a>, known by the shorthand PM 2.5, which burrow deep into the lungs and can even infiltrate the bloodstream, causing cold- and flu-like symptoms in the short term, and heart disease, lung cancer, and other chronic issues over time. "But the fires that raced through Los Angeles burned thousands of homes, schools, historic buildings, and even medical clinics, blanketing the city in thick smoke. For several days after the first fire started, the city’s air quality index, or <a href="https://kolektiva.social/tags/AQI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AQI</a>, exceeded 100, the threshold, typically seen during wildfires, at which air becomes unhealthy to breathe for children, the elderly, and those with asthma. In some parts of the city, the AQI reached 500, a number rarely seen and always hazardous for everyone. "At the moment, air pollution experts know how much smoke fills the air. That’s shown improvement in recent days. But they don’t know what’s in it. 'What are the chemical mixtures in this smoke?' asked Kai Chen, an environmental scientist at the Yale School of Public Health. 'In addition to fine particulate matter, there are potentially other hazardous and <a href="https://kolektiva.social/tags/carcinogenic" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#carcinogenic</a> organic compounds — gas pollutants, trace metals, and microplastics.'"Previous research shows that the spikes in unhealthy air quality seen during such events lead to higher rates of hospitalizations for issues like asthma, and even contribute to heart attacks among those with that chronic disease. A 2024 study on the long-term effects of smoke exposure in California showed that particulate matter from wildfires in the state from 2008 to 2018 contributed to anywhere from 52,000 to 56,000 premature deaths. A health assessment of 148 firefighters who worked the Tubbs Fire, which burned more than 36,000 acres in Northern California in 2017 and destroyed an unusually high number of structures, found elevated levels of the <a href="https://kolektiva.social/tags/PFAS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PFAS</a> known as forever chemicals, <a href="https://kolektiva.social/tags/HeavyMetals" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#HeavyMetals</a>, and flame retardants in their blood and urine."The L.A. County Department of Public Health has formally urged people to stay inside and wear masks to protect themselves from windblown toxic dust and ash. Air quality measurements don’t take these particles into account, which means the air quality index doesn’t reveal the extent of contaminants in the air. "Zhu and her colleagues have been collecting samples of wildfire smoke in neighborhoods near the fires. It’ll be months before that data is fully analyzed, but Zhu suspects she will find a dangerous mix of chemicals, including, potentially, <a href="https://kolektiva.social/tags/asbestos" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#asbestos</a> and lead — materials used in many buildings constructed before the 1970s. "The risk will linger even after the smoke clears. The plumes that wafted over the landscape will deposit chemicals into drinking <a href="https://kolektiva.social/tags/water" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#water</a> supplies and <a href="https://kolektiva.social/tags/contaminate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#contaminate</a># soil. When rains do come, they’ll wash <a href="https://kolektiva.social/tags/ToxicAsh" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ToxicAsh</a> into streams and across the land, said Fernando Rosario-Ortiz, an environmental engineer and interim dean of the University of Colorado Boulder environmental engineering program. 'There’s a lot of manmade materials that are now being combusted. The potential is there for contamination,' he said, noting that little research on how toxic ash and other byproducts of wildfires in urban areas currently exists. 'What we don’t have a lot of information on is what happens now.'"After the Camp Fire razed Paradise, California, in 2018, water utilities found high levels of volatile organic compounds [<a href="https://kolektiva.social/tags/VOCs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#VOCs</a>] in <a href="https://kolektiva.social/tags/DrinkingWater" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DrinkingWater</a>. Similar issues have arisen in places like Boulder County, Colorado, where the Marshall Fire destroyed nearly 1,000 structures in 2021, Rosario-Ortiz said, though the presence of a contaminant in a home doesn’t necessarily mean it will be present in high levels in the water. Still, several municipal water agencies in Los Angeles issued preemptive advisories urging residents not to drink tap water in neighborhoods near the Palisades and Eaton fires. It’ll be weeks before they know exactly what’s in the water. "As wildfires grow ever more intense and encroach upon urban areas, cities and counties must be prepared to monitor the health impacts and respond to them. 'This is the first time I’ve ever even witnessed or heard anything like this,' said Zhu, who raised her daughter in Los Angeles and has lived there for decades, said. 'Even being in the field studying wildfires and air quality impacts, I never imagined that a whole neighborhood, a whole community in Palisades, would burn down.'"Read more: <a href="https://znetwork.org/znetarticle/the-toxic-blend-of-las-urban-wildfire-smoke-will-have-lasting-health-consequences/?utm_source=flipboard&utm_medium=flipboard_rss&utm_campaign=znetwork" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://znetwork.org/znetarticle/the-toxic-blend-of-las-urban-wildfire-smoke-will-have-lasting-health-consequences/?utm_source=flipboard&utm_medium=flipboard_rss&utm_campaign=znetwork</a> <a href="https://kolektiva.social/tags/AirPollution" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AirPollution</a> <a href="https://kolektiva.social/tags/WaterPollution" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WaterPollution</a> <a href="https://kolektiva.social/tags/AirIsLife" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AirIsLife</a> <a href="https://kolektiva.social/tags/WaterIsLife" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WaterIsLife</a> <a href="https://kolektiva.social/tags/ToxicMaterials" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ToxicMaterials</a> <a href="https://kolektiva.social/tags/EnvironmentalDisaster" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EnvironmentalDisaster</a> <a href="https://kolektiva.social/tags/EnvironmentalDamage" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EnvironmentalDamage</a> <a href="https://kolektiva.social/tags/Pyrocene" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pyrocene</a> <a href="https://kolektiva.social/tags/PyroceneEra" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PyroceneEra</a>

Evacuation orders have been issued for some 31,000 people, and an additional 23,000 were told to prepare to evacuate."No lives have been lost or structures reported damaged in the blaze, which is being fought by some 4,000 firefighters."Castaic is a remote, unincorporated part of northern Los Angeles County with a lake that draws many visitors in the summer. It has a population of about 19,000, but is close to the city of <a href="https://kolektiva.social/tags/SantaClarita" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SantaClarita</a>, home to about 224,000 people and the Six Flags Magic Mountain theme park."At a press conference Wednesday evening, local officials speaking in front of large plumes of gray smoke said winds weren’t as strong as during the infernos two weeks ago, allowing them to drop tens of thousands of gallons of retardant from the sky. In addition, firefighters from across the U.S. and overseas have surged to L.A. this month and were able to deploy quickly.“The situation remains dynamic and the fire remains a difficult one to contain, although we are getting the upper hand,” said Los Angeles County Fire Chief Anthony Maroni."Read more: <a href="https://www.msn.com/en-us/weather/topstories/fast-spreading-wildfire-in-los-angeles-county-prompts-evacuations/ar-AA1xFZqo?cvid=30c5303289c749e2b2978dbfbff9d0d1&ei=47" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.msn.com/en-us/weather/topstories/fast-spreading-wildfire-in-los-angeles-county-prompts-evacuations/ar-AA1xFZqo?cvid=30c5303289c749e2b2978dbfbff9d0d1&ei=47</a> <a href="https://kolektiva.social/tags/CaliforniaFires" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CaliforniaFires</a> <a href="https://kolektiva.social/tags/Pyrocene" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Pyrocene</a> <a href="https://kolektiva.social/tags/PyroceneEra" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PyroceneEra</a>
