Sentences with phrase «black soot landing»

Other impacts of human civilization, such as deforestation and other changes to land use, pollution and black soot landing on Arctic snows also contribute to warming.

Not exact matches

These forcings are spatially heterogeneous and include the effect of aerosols on clouds and associated precipitation [e.g., Rosenfeld et al., 2008], the influence of aerosol deposition (e.g., black carbon (soot)[Flanner et al. 2007] and reactive nitrogen [Galloway et al., 2004]-RRB-, and the role of changes in land use / land cover [e.g., Takata et al., 2009].

Recent papers have suggested that various forcings have been significantly underestimated (e.g. various solar influences, black soot, land use changes).

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

These human forcings include greenhouse gas emissions (e.g. CO2, methane, CFCs), aerosol emissions and deposition [e.g., black carbon (soot), sulfates, and reactive nitrogen], and changes in land use and land cover.

«Belching from smokestacks, tailpipes and even forest fires, soot — or black carbon — can quickly sully any snow on which it happens to land.

Using the WRF - chem model, the team first examined how much soot in the form of so - called black carbon would land on snow in the Sierra Nevada, Cascade and Rocky Mountains.
