Study estimates global black carbon emissions up 72% from 1960-2007; BC emissions intensity down 52%

Green Car Congress

A study led by a team from Peking University has estimated that global black carbon (BC) emissions increased from 5.3 teragrams per year in 2007 (+72%). The Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) said BC has a direct radiative forcing of +0.4 (+0.05 Climate Change Emissions Health'

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. The open access study is published in the journal Scientific Reports. Click to enlarge. —Can Li.

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass.

Study projects net cooling of climate from ship emissions through 2050

Green Car Congress

A recent study by an international team calculated that shipping causes a net cooling of climate across all parametrizations of the indirect aerosol effect (IAE) and scenarios throughout the period 1900?2050. A recent study commissioned by the International Maritime Organization (IMO) estimated total emissions of 1046 Tg CO 2 yr ?1

Study associates long-term exposure to air pollution with increasing emphysema

Green Car Congress

Long-term exposure to ambient air pollutants, especially O 3 (ozone), is significantly associated with increasing emphysema, according to a new study led by the University of Washington, Columbia University and the University at Buffalo. The annual averages of ozone levels in study areas were between about 10 and 25 ppb.

Study using paleoclimate data suggests climate sensitivity to CO2 doubling may be less severe than projected

Green Car Congress

The team combined extensive sea and land surface temperature reconstructions from the Last Glacial Maximum (LGM) with a climate model of intermediate. complexity to estimate the equilibrium climate sensitivity for a doubling of atmospheric carbon dioxide concentrations (ECS 2xC ) from. preindustrial times. preindustrial times.
