Arctic Climate Effects of Black Carbon
نویسنده
چکیده
The Arctic is warming about twice as rapidly as the rest of Earth. Black carbon (BC) particles are an important short-lived pollutant that explain a significant fraction of the observed Arctic warming. Most Arctic BC comes from fuel-combustion not from open fires. Arctic climate is very sensitive to the surface warming that BC causes. BC appears to warm the Arctic more than any other agent except CO2. Reducing the concentration of Arctic BC now will cool the planet more than a delayed reduction.

Arctic climate sensitivity to local black carbon
[1] Recent attention has focused on the impact of black carbon (BC) on Arctic climate. Here, idealized equilibrium climate experiments are conducted to explore the dependence of Arctic temperature change on the altitude and season of local BC forcing. BC residing in the lowest atmospheric layer produces very strong Arctic warming per unit mass and forcing [2.8 ̇ 0.5 K (W m–2)–1] because of low c...
متن کاملArctic Air Pollution
I n the face of rapid climate change in the Arctic (increasing temperatures, earlier onset of spring snowmelt, sea ice loss, etc.), it is important to improve our knowledge about processes driving these changes. In general, climate models are able to reproduce enhanced warming in the Arctic, the so-called Arctic amplification. However, discrepancies are apparent between observations and global ...
متن کاملQuantifying the Potential for Low-Level Transport of Black Carbon Emissions from Cropland Burning in Russia to the Snow-Covered Arctic
Short lived aerosols and pollutants transported from northern mid-latitudes have amplified the short term warming in the Arctic region. Among those black carbon is recognized as the second most important human emission in regards to climate forcing, behind carbon dioxide, with a total climate forcing of +1.1 Wm−2. Studies have suggested that cropland burning may be a large contributor to the bl...
متن کاملThe sources of atmospheric black carbon at a European gateway to the Arctic
Black carbon (BC) aerosols from incomplete combustion of biomass and fossil fuel contribute to Arctic climate warming. Models-seeking to advise mitigation policy-are challenged in reproducing observations of seasonally varying BC concentrations in the Arctic air. Here we compare year-round observations of BC and its δ(13)C/Δ(14)C-diagnosed sources in Arctic Scandinavia, with tailored simulation...
متن کاملA Modelling Study of the Impact of On-Road Diesel Emissions on Arctic Black Carbon and Solar Radiation Transfer
Market strategies have greatly incentivized the use of diesel engines for land transportation. These engines are responsible for a large fraction of black carbon (BC) emissions in the extra-tropical Northern Hemisphere, with significant effects on both air quality and global climate. In addition to direct radiative forcing, planetary-scale transport of BC to the Arctic region may significantly ...
