	View Edit Domain: BioEnergy Title: * Body: A new study has found that the quickest, best way to slow the rapid melting of Arctic sea ice is to reduce soot emissions from the burning of fossil fuel, wood and dung.<br /> <br /> According to Stanford researcher Mark Z. Jacobson analysis, soot is second only to carbon dioxide in contributing to global warming. But, he said, climate models to date have mischaracterized the effects of soot in the atmosphere.<br /> <br /> Because of that, soot's contribution to global warming has been ignored in national and international global warming policy legislation, he said.<br /> <br /> "Controlling soot may be the only method of significantly slowing Arctic warming within the next two decades," said Jacobson, director of Stanford's Atmosphere/Energy Program.<br /> <br /> "We have to start taking its effects into account in planning our mitigation efforts and the sooner we start making changes, the better."<br /> <br /> To reach his conclusions, Jacobson used an intricate computer model of global climate, air pollution and weather that he developed over the last 20 years that included atmospheric processes not incorporated in previous models.<br /> <br /> He examined the effects of soot - black and brown particles that absorb solar radiation - from two types of sources.<br /> <br /> He analyzed the impacts of soot from fossil fuels - diesel, coal, gasoline, jet fuel - and from solid biofuels, such as wood, manure, dung, and other solid biomass used for home heating and cooking in many locations. He also focused in detail on the effects of soot on heating clouds, snow and ice.<br /> <br /> What he found was that the combination of both types of soot is the second-leading cause of global warming after carbon dioxide.<br /> <br /> He also found that soot emissions kill more than 1.5 million people prematurely worldwide each year, and afflicts millions more with respiratory illness, cardiovascular disease and asthma, mostly in the developing world where biofuels are used for home heating and cooking.<br /> <br /> Jacobson's study will be published this week in Journal of Geophysical Research (Atmospheres). <br /> <br /> © 2007 - Jingle Info Solutions : All rights reserved <br /> Captcha: Please Enter Code : * Time Zone: * Select the time zone Vocabularies Newsletter: Domain: Show summary in full view Input format Filtered HTML Web page addresses and e-mail addresses turn into links automatically.
