 Even when a wood burner is technically permitted construction hurdles can push homeowners toward alternatives    For example finding a skilled mason in a small town can be difficult and expensive    And once a wood burning fireplace is built air quality alerts or high fire risks can trigger temporary usage bans    There is a possibility you may not even be able to start a fire when you want to Meanwhile the mechanics of a hearth can be a mystery for homeowners raised in climate controlled homes    The lack of skill is more than just frustrating it is  a safety concern    In Park City Utah a three level townhome burned to the ground after renters mismanaged a fire    While many owners want a wood burner in theory they rarely want the work    The romantic image of the homeowner chopping wood often collapses under the practical reality of soot ash and spiders in the wood pile it is  totally about the cozy ambience No one has ever said to me I want to chop my wood light my fire and clean out all those ashes    A popular compromise is the gas starter which helps a homeowner to ignite real logs    In areas where wood burners are banned some install high tech water vapor units that use water mist and lights to mimic the visual of fire without the smoke    But in the most exclusive tier of the market fireplace labor is simply outsourced as a concierge service    Property managers bring in wood stack it properly in the fireplace and clean up afterward    In Utah at a famous Lodge for instance unit owners and guests can enjoy a real fire without lifting a finger    As a complimentary service bell staff can be dispatched to place the kindling and light the match    They then depart    Fire is out? Housekeeping handles the cleanup of course  

13 Vermont           wood burning              RAWSEP View     What does the word inadvertently mean?     Inadvertantly is an adverb which means unintentionally or while not focusing the mind on a matter or while being inattentive        A Scientist who follows the science does not come to conclusions unintentionally or in an unfocused way or by not paying attention to the facts that arise during scientific experiments unless one is only called a scientist but only goes through the motions of conducting an experiment but is inattentive to what the results tell the scientist      At the end of this Abstract the scientist author states   These findings suggest that more thorough and better monitoring of biomass burning emissions are necessary to ensure that the transition to wood fuel does not inadvertently cause harm to public health      So the conclusion is that wood burning causes harm to human health     But the scientist tiptoes around this conclusion because traditionally wood burners have been assured that because photosynthesis conducted by trees planted to replaced burned trees sequester some carbon even if the carbon is produced by the burning of trees themselves     But the editor of RAWSEP read a research paper from 2024 which concluded that living trees close their pores against the PM 2 point five produced by nearby wood burning and when living tree pores are closed the living tree cannot conduct photosynthesis so in these conditions Carbon Dioxide produced by nearby wood burning is not sequestered by photosynthesis and so the living tree when encountering Biomass Burning or Fossil Fuel Burning does not sequester Carbon     So the advantage of burning wood and replacing the burned wood with a living tree does not slow climate change any faster than burning fossil fuels    The idea that burning wood is better for the climate than fossil fuel burning is a lazy assumption assumed to make wood burners feel something that is not a fact    Because wood burning emits 2 point 8 times the PM two point five as coal burning and wood burning emits Four Hundred Fifty Times the PM two point five as the fossil fuel natural gas burning you come out of wood burning behind in any attempt to slow climate change      After burning wood you end up blocking photosynthesis in nearby living trees and therefore you end up with more PM two point five as well as more CO2 in the atmosphere from wood burning than from fossil fuel burning    This study also concludes that lead is released into the atmosphere from wood burning      The editor of RAWSEP in direct statements of fact concludes that Unintentionally Burning wood does not inadvertently cause health problems for instance from lead exposure      Unintentionally Burning wood predictably causes health problems for instance from lead exposure The climate benefits from burning wood are worse than the climate benefits from burning coal or burning natural gas  The climate benefits from burning wood compared to burning fossil fuels do not exist     There should be no transition from fossil fuel to wood fuel    There is no scientific basis for any transition from fossil fuel to wood fuel in order to slow climate change     Transition to wood fuel instead hastens climate change    Scientists should be urging a transition to clean energy to replace the obsoletely polluting in terms of environmental health and human health     How these scientists are paid for their research can probably be traced to their being paid for these weak and inattentive conclusions by the payment from the wood burning industry        From the article headline         Back to the future trace lead in ambient air from wood fuel combustion           Nature       April 22 2026              While wood burning promises potential climate benefits in reducing fossil fuels usage it also poses significant risks related to air pollution and  Abstract            Background         Deciding to classify wood as a renewable resource for residential space heating is a contentious issue because it balances a relatively inexpensive fuel against the public health risks of wood smoke exposure              Objective           To investigate wood fuel emissions as a source of trace lead exposure via ambient air in the northern regions of the United States US         Methods          Federal Reference Methods filters n equals 182 were obtained from the state of the Vermont Department of Environmental Conservation from Rutland n equals 97 and New Hampshire Department of Environmental Services from Keene n  equals 85    Filter samples were collected during the winters of 2011–2016 and analyzed by Energy Dispersive X ray Fluorescence    Chemical speciation data was compiled from 22 national sites via the Interagency Monitoring of Protected Visual Environments and EPA Chemical Speciation Network CSN which were compared to the concentrations of wood smoke emissions observed across northeastern US        Results            Our evidence indicates a link between wood burning emissions with increased concentrations in particle bound lead that is associated with wood combustion    Linear regression models in Keene NH R2 equals  0 point 438 and Rutland VT R2 equals  0 point 341 indicate moderate agreement between tracers of wood smoke and lead suggesting a common source    On average lead concentrations ranged from 0 point 86  nanograms per cubic meter in the Rocky Mountains Region to 1 point 70 nanograms per cubic meter in the Southeast Region    We observed varying correlations between lead and potassium across the US with slight to modest agreement R2 equals  0 point 09 to 0 point 47 at most sites the strongest associations were on the Pacific Coast R2 greater than  0 point 40    This suggests that a strong relationship between potassium and lead is observed at many nationwide locations           Significance            Wood burning an activity common in many rural parts of the US is a likely anthropogenic source of lead introduced into ambient air throughout the northern portion of the US in the winters of Two Thousand Eleven to Two Thousand Sixteen    These ambient lead exposures are likely to have long term adverse public health impacts           Impact           While wood burning promises potential climate benefits in reducing fossil fuels usage it also poses significant risks related to air pollution and human exposure to toxic substances like lead    These findings suggest that more thorough and better monitoring of biomass burning emissions are necessary to ensure that the transition to wood fuel does not inadvertently cause harm to public health

Ms Healey is aware of the risks wood burners can pose    With that in mind she set out to track just how many potentially harmful particles her parents are regularly being exposed to    In order to investigate Ms Healey used an air quality monitor in the living room for five days measuring levels of PM2 point 5 and PM10   pollution particles in the air in micrograms per cubic meter    For example a result of 1 micrograms per cubic meter would mean that everyone cubic meter of air contains one microgram of PM    PM2 point 5 has been linked to a range of serious health problems including stroke cardiovascular disease lung cancer and chronic respiratory infections    Short term effects can also include coughing breathing difficulties headaches infections of the eyes nose and throat as well as skin irritation allergies and acute lower respiratory infections    After analyzing the air in the house of her parents for five days Ms Healey found that PM2 point 5 levels were far higher when the wood burner was in use compared to when it was not    During burning periods PM2 point 5 readings ranged from 4 point 91 micrograms per cubic meter on day one to 11 point 94 micrograms per cubic meter on day five    It exceeded 11 micrograms per cubic meter on three of the five days    By contrast pollution levels were below 1 micrograms per cubic meter on four out of five days when the wood burner was not in use hitting a high of 1 point 74 micrograms per cubic meter on day five    She also found air pollution spiked sharply after the stove was lit     On one evening levels of PM TWO POINT FIVE were between 0 micrograms per cubic meter and 1 micrograms per cubic meter before she used the wood burner     After lighting it at 7 10 pm levels of the pollutant averaged at 16 point 24 micrograms per cubic meter before tapering down to 10 point 07 micrograms per cubic meter between 9pm and 10pm    The highest pollution level recorded during the study by Ms Healey was 24 point 46 micrograms per cubic meter         Official guidance by the World Health Organization states that the recommended limit for average PM TWO POINT FIVE exposure over a 24 hour period is 15 micrograms per cubic meter  meaning the average of the results of Ms Healey sat below that threshold    However Professor James Allan professor of air pollution measurement at the University of Manchester warned that even studies of relatively low levels of air pollution have found adverse health effects   He told Which? In addition it seems that particulate matter from wood burning is a particularly harmful form of pollutant   Doctor James Heydon associate professor at the school of sociology and social policy at the University of Nottingham added Research suggests that PM TWO POINT FIVE is especially damaging to your health because it can enter your bloodstream which means it can cause inflammatory responses throughout the body   Ms Healey concluded that while she remains unsure exactly how harmful the wood burner of her parents is it has made them reconsider how often they use it     She said We have decided we will not continue to use it every single night as we do not feel it is  worth the potential health risks of even low levels of daily PM exposure    We will not stop using it altogether but will consider it to be a treat for special occasions rather than something to do every day   Her findings come just months after tighter restrictions and guidelines were introduced for wood burners in Britain    As well as announcing that stoves would carry warning labels ministers also proposed cutting the limit on smoke emitted from wood burners by 80 per cent to one gram per hour    However the long awaited measure would apply only to new wood burners many of which already meet the stricter limits    Emma Hardy the air quality minister said Dirty air robs people of their health and costs our NHS millions each year to treat lung conditions and asthma    We are determined to clean up our air    By limiting emission levels and introducing new labels as outlined in our consultation families will be able to make better healthier choices when heating their homes    The restrictions are predicted to cut annual toxic emissions from wood burning in the UK by just 10 per cent over the next decade but campaigners said the measures do not go far enough

23A Ukraine           JD Vance brags about halting Ukraine aid sources say he is not just talking he is driving policy       US Vice President JD Vance in Budapest Hungary on April 7 2026    US Vice President JD Vance in April openly praised the Trump decision to halt direct US weapons transfers to Ukraine a statement that drew criticism and highlighted his skepticism toward Kyiv    it is  one of the things I am proudest      we have told Europe that if you want to buy weapons you can but the US is not buying weapons and sending them to Ukraine anymore Vance said at a Turning Point event    His comments immediately drew backlash coming at a time when Russia continues daily strikes against Ukrainian cities and infrastructure    US Representative Marcy Kaptur said the policy shift effectively benefits Moscow    Not good for America    Not good for Europe    Not good for Ukraine    This is only good for Russia she said in a statement    At the same time as the Kyiv Independent has learned Vance is not merely echoing the Trump  foreign policy he is actively shaping it    Vance has emerged as one of the key voices influencing the Trump approach to Ukraine according to sources familiar with internal discussions    A worldview formed before the war      The Vance criticism of Ukraine did not begin in office    Long before his now famous Oval Office clash with President Volodymyr Zelensky he had already positioned himself as a skeptic of US support for Kyiv    In early Two Thousand Twenty Two as global attention focused on the growing threat of war against Ukraine Vance then a Senate candidate dismissed the issue in stark terms    I got to be honest with you I do not really care what happens to Ukraine one way or another he said during an interview    President Volodymyr Zelensky L US President Donald Trump C and Vice President JD Vance R meet in the Oval Office of the White House in Washington D   C    US on February 28 2025    The comment widely criticized at the time captured a core element of the Vance thinking Ukraine in his view does not represent a US national interest    From the earliest days of The Russian war he has framed the biggest conflict in Europe since World War II as a burden on American resources    Vance has criticized the scale of US assistance approved under former President Joe Biden while saying NATO allies have failed to shoulder enough of the burden    This framing has become a central pillar of the Vance foreign policy identity    Contrasts within his own circle      At the same time the Vance stance on Ukraine stands in stark contrast not only to US allies but also to members of his own family and closed circle    His cousin Nate Vance traveled to Ukraine in March Two Thousand Twenty Two initially to deliver humanitarian aid before joining Ukrainian forces    Over three years he fought in some of the most intense battles of the war as part of the Da Vinci Wolves battalion    Speaking to the Kyiv Independent Nate Vance said he disagreed with the earlier remarks by Vance about not caring about Ukraine    it is  fair to say that I do not agree with that statement he said    But you have to take that comment in context    He was not a politician yet    it is  politics    Similar divergences also appear within the Vance broader professional circle    Driscoll US Secretary of the Army and a close ally of Vance and his former Yale Law School classmate has taken a more supportive tone on Ukraine    The US Army has stood by and stood with the Ukrainians from the very first day of the war Danel Driscoll said on April 16    They have done an absolutely amazing job of innovating    And I am publicly on record saying we are learning a lot from them    Back in December Driscoll who was appointed on the Vance recommendation traveled to Kyiv and even took part as a US negotiator on Ukraine    This difference between the Vance remarks and senior military views points to deeper internal disagreements over The Ukraine status as a US ally    Read full article
