Not exact matches

Cutting that source of black carbon could help reduce the estimated 1.5 million premature deaths per year attributed to biofuel soot, Jacobson said.

Cutting the black carbon, or soot, produced by burning fossil fuels, vegetation, dung and other sources could reduce global warming

«If our interpretation is correct, then reducing the amount of black carbon or soot may help diminish the intensity of floods in the south and droughts in the northern areas of China, in addition to having human health benefits,» notes co-author James Hansen of the Goddard Institute.

One high - profile target, he says, should be reducing emissions of tiny soot particles, known as black carbon, that don't last long in the atmosphere but have an outsize impact on warming.

Since, on average, aerosols have a cooling effect (although some absorbing aerosols like black carbon (soot) are actually adding to global warming), reducing current aerosol levels (particularly sulphates) is equivalent to an extra warming effect.

Reducing emissions of the short - lived climate forcers black carbon and tropospheric ozone — soot and smog — has been identified by scientists as the most effective strategy to slow Arctic warming and melting in the near term, forestalling potentially irreversible tipping points such as the melting, while the world works to reduce emissions of GHGs.

However, by aggressively cutting emissions of soot (black carbon), methane and air pollution (specifically tropospheric ozone), we can reduce the speed that the situation worsens.

And, our work on reducing black carbon, or soot, will decrease the rate of snow and ice melt in the Arctic.

It's ironic that misinformed environmentalists blame ethanol for deforestation, when in some parts of the world, it's actually helping to reduce respiratory disease, infant mortality, and black carbon soot from burning trees.

With IdleAir, truck stop communities enjoy cleaner air with the reduction of black carbon and soot that emit from diesel engines, reduced noise pollution, local job creation, and an increased tax base for the local economy.

Instead, ministers from 25 countries will co-operate to vastly reduce black carbon (better known outside these talks as soot), as well as methane and ozone in the atmosphere — substances known collectively as short - lived climate pollutants.

The largest immediate impact will come from reducing powerful but relatively short - lived pollutants, like black carbon (especially soot from cooking fires), methane, and HFCs (hydrofluorocarbons, used in cooling equipment), and by stabilizing the world's forest cover.

Reductions in some short - lived human - induced emissions that contribute to warming, such as black carbon (soot) and methane, could reduce some of the projected warming over the next couple of decades, because, unlike carbon dioxide, these gases and particles have relatively short atmospheric lifetimes.The amount of warming projected beyond the next few decades is directly linked to the cumulative global emissions of heat - trapping gases and particles.

«Comparing the amount of warming in the U.S. saved by reducing our greenhouse gas emissions by some 80 % to the amount of warming added in the U.S. by increases in Asian black carbon (soot) aerosol emissions (at least according to Teng et al.) and there is no clear winner.

Making diesel an even more attractive candidate for attack is the fact that reducing much of its black carbon emissions might simply be a matter of upgrading old, soot - spewing engines with newer technology.

It's even more attractive because black carbon washes quickly out of the atmosphere, and so reducing soot emissions would lead to a fast fall in the concentration of black carbon in the atmosphere.

If black carbon is responsible for trapping so much heat, then reducing soot may be an effective way to slow down the planet's warming.
