20th-century industrial black carbon emissions altered Arctic climate forcing.
Black carbon (BC) from biomass and fossil fuel combustion alters chemical and physical properties of the atmosphere and snow albedo, yet little is known about its emission or deposition histories. Measurements of BC, vanillic acid, and non-sea-salt sulfur in ice cores indicate that sources and concentrations of BC in Greenland precipitation varied greatly since 1788 as a result of boreal forest...

متن کاملBiomass and carbon budget of European forests, 1971 to 1990.
In severely polluted areas, such as locally in Montshegorsk in northwestern Russia, all trees have died. However, measurements from Austria, Finland, France, Germany, Sweden, and Switzerland show a general increase of forest resources. The fertilization effects of pollutants override the adverse effects at least for the time being. Biomass was built up in the 1970s and 1980s in European forests...
متن کاملThe carbon budget of Canadian forests: a sensitivity analysis of changes in disturbance regimes, growth rates, and decomposition rates.
Ecosystem responses to climate changes will affect the exchange of carbon (C) with the atmosphere, thus providing feedback for future climate response. We have developed a C budget model of Canadian forests and forest sector activities and used sensitivity analysis runs with changes in productivity, decomposition, and disturbance regimes to assess the sensitivity of the Canadian forest sector C...
متن کاملInto the 20th Century
At the beginning of the 20th century descendants of the early European settlers who first colonized the coasts of Virginia, the Carolinas, and Georgia were established throughout the region. Most all of the native people had been displaced. Cotton was king. The mature forests were being . the southern world, wavered and then toppled. Demand for the South’s cotton declined due to new competition...
