Black carbon, a key component of soot, plays a much larger role in global warming than previously estimated, scientists have found.

Both agricultural burning and diesel engines yield dark sooty particles scientists call black carbon.

Black carbon absorbs solar radiation, warming the atmosphere.

The good news is, while CO2 stays in the atmosphere for a century, black carbon lingers for a much shorter time.

In Asia and Africa, stoves produce the bulk of black carbon, although it also emanates from diesel engines and coal plants there.

The great swinging pulverizer is the key - apparatus for producing the black carbon productions in our plant.

STATIONERY ARTICLES. REQUIREMENTS FOR BLACK CARBON PAPER FOR TYPEWRITERS.

Doctors have long railed against black carbon for its devastating health effects in poor countries.

am the sun: It seems so black carbon-like.

That's key, because if the world could reduce black carbon emissions soon, it could help blunt warming almost instantly.

Black carbon has particularly pernicious effects on frozen regions.

Black carbon has newly emerged as the second biggest contributor to climate change.

"The lifetime of black carbon is pretty short, about one to two weeks on average, " Jacobson said.

Particulate matter, particularly black carbon from cooking fires and coal-fired plants in India, is the real culprit.

The porous carbons including carbon black, carbon aerogel and multiwall carbon nanotube were studied.

Black carbon dye depositing in the lymph nodes'surface were observed in all postmortem lymph nodes.

Black carbon is produced by diesel engines and primitive stoves burning wood and cow dung.

Methane is the most important of these gases, followed by black carbon and nitrous oxide.

Black carbon slopping over India's bathtub rim represents a threat to Asia's high glaciers.

Bush fires in Australia leave high levels of black carbon in the soil for hundreds of years.

The team assumed that Virgin Galactic's rubber-burning engine would emit 60 grams of black carbon per kilogram of fuel burned.

Shindell added that the scientific understanding of black carbon's impact varies by region.

And some of the gunk, notably soot or "black carbon" , can warm the planet, too.

Black carbon is also causing Himalayan glaciers to melt, threatening water supplies for hundreds of millions of people.

The severe impact of black carbon (soot) on climate change has been known about for years.

Studies of an ice core from Mount Everest show that from 1975 to 2000 the black carbon rose threefold.

Kerosene-burning rocket engines not associated with space tourism emit 20 to 40 grams of black carbon per kilogram.

Shindell said climate models from NASA GISS and elsewhere show that 15 to 55 percent of global warming is due to black carbon.

The wide range is primarily because of incomplete knowledge about how black carbon and clouds interact.

Combustion is incomplete, so a lot of black carbon (soot) is emitted.

"Because black carbon has a short lifetime, if you can remove it, you can have a fast climate impact, " Jacobson said.

That is because black carbon lingers in the atmosphere for one to four weeks, compared to CO2's lifetime of centuries to millennia.

Black carbon is produced from the incomplete combustion of wood, biomass such as crop residues and fossil fuels.

And here's a list of the items I want for my office: two boxes of black carbon paper , some blotting- paper and some adhesive tape.
