Soot (pron.: /ËsÊt/) is impure carbon particles resulting from the incomplete combustion of hydrocarbons. It is more properly restricted to the product of the gas-phase combustion process but is commonly extended to include the residual pyrolyzed fuel particles such as coal, cenospheres, charred wood, petroleum coke, and so on, that may become airborne during pyrolysis and that are more properly identified as cokes or chars.
Besides ever thinning ice, permafrost melting, soot deposits, habitat loss, you might as well add another significant factor threatening the arctic ecosystem – mercury. For some time, the alarmingly high mercury concentrations in the regions were rather unaccounted for, in part, however a new research by scientists at Harvard’s Atmospheric Chemistry Modeling Group suggests that [...]
An international team of scientists showed that simple, inexpensive measures to cut emissions of two common pollutants will significantly slow global warming, boost crop production throughout the world and save many lives in the process. The climate change debate is traditionally centered around carbon dioxide emissions – one of the major problems and causes of [...]
Record low ice volumes in the arctic caused by global warming have been reported this year, and if there are still some climate skeptics among you, recent events concerning trading in the region might provide proof enough of dramatic change. Supertankers and giant cargo ships could next year travel regularly between the Atlantic and Pacific [...]
It is no longer a question if multi-meter sea level rises will happen, but only of when. According to the latest estimate from the Arctic Monitoring and Assessment Programme it seems the accelerated climate change in the Arctic including a thaw of Greenland’s ice could raise world sea levels by up to 1.6 meters by [...]
An international research team is in the land of snow and ice, in search of soot or black carbon, in an effort to judge whether or not it is responsible for the alarming rapid warming in the area lately. The research team includes scientists from Norway, Russia, Germany, Italy, and China, whose members are working [...]
Most of the talk about global warming revolves around carbon dioxide, sometimes giving the false impression that it alone is responsible for global warming and all its implications. However, numerous studies have revealed a new enemy, one almost as dangerous as carbon dioxide: soot. The black powdery pollutant is responsible for numerous climatic shifts, especially [...]
