IMO progress on black carbon in Arctic ‘welcome but long overdue’
The decision at the International Maritime Organisation (IMO) to recommend to its environment committee a definition of black carbon arrived at by scientific consensus, after four years of debate, has been welcomed by environmental NGO Transport & Environment. Lack of agreement at sub-committee level had been holding up technical work to calibrate and test black carbon measurement methods ...

Black carbon a significant factor in melting of Himalayan glaciers
The fact that glaciers in the Himalayan mountains are thinning is not disputed. However, few researchers have attempted to rigorously examine and quantify the causes. Lawrence Berkeley National Laboratory scientist Surabi Menon set out to isolate the impacts of the most commonly blamed culprit—greenhouse gases, such as carbon dioxide—from other particles in the air that may be causing the ...

Fine particles trap more heat in atmosphere than previously thought
Fine particles in the air produced by road transport trap more radiation in the earth's atmosphere than previously estimated, and therefore may contribute more to global warming than realised, according to new research. In contrast, the impact of particles from shipping appears to reflect more radiation than previously thought, whilst the effect of particles from aviation is comparatively small. ...

Black carbon pollution emerges as major player in global warming
Soot from biomass burning, diesel exhaust has 60 percent of the effect of carbon dioxide on warming but mitigation offers immediate benefits. Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists ...

Goodyear Announces Industry’s First Tyre To Use Carbon Black Produced Via Methane Pyrolysis
Monolith has provided SCB for Goodyear’s recently announced new tread formulation for its ultra-high performance, all-season ElectricDrive GT tyre, tuned for electric vehicles, in size 235/40R19. A new tyre is nothing surprising min itself, but this latest offer from Goodyear includes Monolith’s sustainable carbon black developed by plasma pyrolysis of Methane. The specialised tread ...

New particulate measurement technology enables climate change ‘quick hit’
More accurate measurement of Black Carbon particles is now within reach of UK local authorities, air quality and climate change researchers and industry thanks to a highly-specified device, newly available via Enviro Technology. Reducing levels of Black Carbon in the air improves human health and slows climate change. Because it is dark, Black Carbon absorbs a lot of heat from the sun and it ...

Industrial pollutant melted European glaciers
Industrial emissions of black carbon were responsible for the retreat of the glaciers in the European Alps that marked the end of the so-called ‘Little Ice Age’, according to a new study. The researchers explain how black carbon deposits could have caused glaciers to melt more rapidly from the mid-19th century and suggest that human activities were already having a visible influence ...

C2ES Outlines Steps to Cut U.S. Emissions of Short-Lived Climate Pollutants
As evidence mounts that climate change is increasing the risks of extreme weather, the Center for Climate and Energy Solutions is outlining steps the federal government can take to reduce short-lived climate pollutants affecting our climate now. In a policy brief being released today, Domestic Policies to Reduce the Near-Term Risks of Climate Change, C2ES identifies a range of administrative ...

Effects of electric vehicles on the climate
A new study suggests that a 50 per cent reduction in road transport emissions as a result of using more electric vehicles will result in a cooling effect on the climate. The researchers compared the overall impact on climate and air quality of sourcing electric power for vehicles from zero carbon sources, such as wind and solar power, and sourcing it from standard power plants. Road transport ...

US-Canada pact eases Arctic fears
A joint pledge by the US and Canada to reduce methane emissions for oil and gas activities in the Arctic and limit fossil fuel extraction is putting pressure on Russia to follow suit. The pledge was in response to increasing concern across the world at the intention of the eight nations with territorial claims in the Arctic to exploit its resources, even though this risks making climate change ...

IMO’s ‘Polar Code’ ignores environmental dangers of increased Arctic and Antarctic shipping
The new draft ‘Polar Code’ of safety and environmental rules fails to address the looming danger of having non ice-strengthened and poorly prepared ships in supposedly ‘ice-free’ polar waters, environmental organisations have warned. The final draft, drawn up today by the International Maritime Organisation (IMO), governs ships operating in Arctic and Antarctic waters. ...

Tibetan plateau melts in the face of climate change
Climate change is affecting the Tibetan plateau, threatening regional water supplies and altering atmospheric circulation for half the planet. The plateau is the world's third largest store of ice. But its temperature has risen by up to 0.3 degrees Celsius every ten years over the last fifty years — approximately three times the global warming rate. As a result, 82 per cent of the plateau's ...

U.S. EPA awards U.C. Berkeley $1.5 million to evaluate air pollution in developing nations
The U.S. Environmental Protection Agency today announced it is awarding the University of California, Berkeley, a $1.5 million grant for work to assess the impact of pollution from household and village-scale stoves on air quality in developing countries. The grant is part of $9 million awarded nationally to six universities to research cleaner technologies and fuels for cooking, lighting, and ...

Four fast-action strategies to tackle abrupt climate change
A new study has assessed the potential of several 'fast-action' climate change mitigation strategies. Key options are reducing use of hydrofluorocarbons (HFCs), reducing emissions of black carbon and ozone-forming pollutants, and sequestering carbon through afforestation and biochar production. Research has indicated that current emissions of greenhouse gases (GHGs) have committed the planet to ...

Low-sulphur marine fuels work!
Requiring ships to use low-sulphur fuels and slow down makes a massive difference to air pollution, according to a new study from America. The US National Oceanic and Atmospheric Administration took emissions readings from a commercial container ship using high-sulphur fuels, and then compared them to readings from the same ship using low-sulphur fuels and reducing its speed from 22 knots to 12 ...

Rifts emerge over why Arabian cyclones are strengthening
People living in countries around the Arabian Sea have been exposed to tropical cyclones that have been growing in strength since 1997, and hitting the area earlier than usual — but scientists are still debating what is driving these changes. A study published in Nature last month (20 September) challenges previous conclusions that the stronger cyclones are being driven by man-made ...

Yale Awarded $1.5 Million EPA Grant for Research on Cleaner Emissions from Cookstoves
Yale University is one of only six recipients of EPA grant funding intended to advance research into cleaner technologies and fuels for cooking, lighting and heating homes. Yale will collaborate with researchers from the Universities of Minnesota, Georgia, and British Colombia, as well as North Carolina State and two Indian non-governmental organizations. The group will receive nearly $1.5 ...
