Wood Smoke/black Carbon Soot: a Major Cause of Global Warming
3:21 am | Author: RobertSouthey | Posted in Science

Inside the frenzied hunt for methods to the global warming crisis, climatologists, policy makers as well as other concerned environmentalists have overlooked one of the main causes of rising temperatures round the globe-soot—the black residue that coats fireplaces and darkens vehicle exhaust. Black carbon soot may in fact function as the second largest contributor to climatic change near the greenhouse gas fractional co2.

Based on Stanford environmental engineering Professor Mark Z. Jacobson, “Soot, or black carbon, might be in charge of 15 to 30 % of global warming, yet it isn’t even considered in most of the discussions about controlling climate change.” (“Nature”, ScienceDaily, Feb. 9, 2001). Jacobson also observed that human beings produce the majority of the soot particles that pollute the atmosphere. He maintains that soot consists primarily of elemental carbon understanding that 90 percent of it comes from the consumption of non-renewable fuels (particularly coal, diesel fuel, jet fuel, gas main, kerosene) and the burning of wood as well as other biomass. Jacobson also claims which a worldwide decrease in soot emissions and controlling biomass burning could quell the alarming pace of global warming plus reduce our attachment to soot-producing fuels. ( http://www.sciencedaily.com/releases/20 ... 075206.htm.)

Besides its affect our planets atmosphere, soot is detrimental to improve your health. The World Health Organization reports that approximately 2.7 million people die annually from polluting of the environment understanding that reduction of wood along with other biomass burning would mitigate climatic change and would also save lives and improve people’s health.

Other numerous studies have dispelled the myth that burning wood and also other biomass is “green or carbon neutral” knowning that the fine particulates emitted through the combustion process actually hasten climate change. (http://www.burningissues.org under both “Science” and “Global Warming” headings).

Atmospheric scientist V. Ramanathan from the Scripps Institution of Oceanography and University of Iowa chemical engineer Greg Carmichael discovered that “black carbon soot, from burning wood and also other biomass, cooking with solid fuels, and diesel exhaust features a warming effect inside the atmosphere three to four times higher than prevailing estimates.” (Nature Geoscience 1, 221-227 (March 24, 2008). They calculated that soot as well as other varieties of black carbon particulates may represent as much as 60 % in the current climate change effect of co2 along with their findings correlated concentrating on the same studies from Stanford, Caltech, and NASA.

A simplified explanation for the warming effect is wood smoke’s fine particulates thin clouds. So that as total airborne particulates increase, cloud cover decreases, allowing more sunlight to arrive at our planet. According to Ramanathan, approximately 35 % of black carbon in the global atmosphere arises from India and china. Yet per capita emissions of black carbon soot from your United States and several Countries in europe remains to be similar to those from Asia. Ramanathan’s research also found that the warming effects of black carbon smog seem to be accelerating the melt of Himalayan glaciers, ultimately causing early drying of an major supply of drinking water for vast amounts of people throughout Asia.

The International Global Panel on Java prices (IGPCC) agreed that black carbon soot can be a major contributor to global warming

The 2007 Nobel-winning IGPCC panel of around two thousand scientists figured black carbon soot features a dire atmospheric warming effect. This was significant because soot had previously been unaddressed like a major reason for global warming. Nor had the amplification of black carbon’s warming effect previously been taken into account when mixed with other aerosols, creating additional secondary fine particulates.

Studies of fine particulates from wood smoke in several communities

An EPA study cites that “In some neighborhoods, on some days, 90% with the particle pollution is produced by residential wood burning.” (Jane Koenig and Timothy Larson, A listing of Emissions Characterization and Non-Cancer Respiratory Outcomes of Wood Smoke, USEPA DOC #453/R-93-036,1-919-541-0888).

A report by 50 % San Jose, California locations showed that wood smoke pollution was 4.4 times that regarding gasoline or diesel fueled vehicles. (“A Comparison of Source Apportionments of proper Particulate Matter at Two San Jose, CA Locations,” from San Jose Speciation Trends Network.)

The next thing

As the urgency of reducing black carbon emissions can’t be overstated, reducing soot from wood smoke would offer nearly instant benefits in improving atmospheric conditions in the us. It would also provide immediate societal and health advantages. This would facilitate political and regulatory momentum towards mitigation of black carbon emissions.

It can be urgent to advance public awareness of wood smoke’s crucial role in global warming with education and changes to our policy.

For those considering more scientific and academic data about wood smoke, see http://www.burningissues.org. The Burning Issues site was founded in 1988 as a special particulate pollution project from the San fran Loma Prieta/Silicon Valley Chapter of the Sierra Club.

• The Surgeon General has determined that there is no safe level of exposure to ambient smoke!

• If you smell even a subtle odor of smoke, you are being exposed to poisonous and carcinogenic chemical compounds!

• Even a brief exposure to smoke raises blood pressure, (no matter what your state of health) and can cause blood clotting, stroke, or heart attack in vulnerable people. Even children experience elevated blood pressure when exposed to smoke!

• Since smoke drastically weakens the lungs' immune system, avoiding smoke is one of the best ways to prevent colds, flu, bronchitis, or risk of an even more serious respiratory illness, such as pneumonia or tuberculosis! Does your child have the flu? Chances are they have been exposed to ambient smoke!
