Australian scientists have developed a method for trapping carbon dioxide that they say could ultimately reduce the costs of separating and storing carbon from fossil fuel emissions.
Writing in the Journal of the American Chemical Society, researchers from the University
Putting a speed limit on cargo ships as they sail near ports and coastlines could cut their emission of air pollutants by up to 70 percent, reducing the impact of marine shipping on Earth’s climate and human health, scientists have found. Their evaluation of the impact of vessel speed reduction policies, such as those proposed by the California Air Resources Board,
As Fall turns leaves to colorful displays, starting in northern New England, and moving ever southward as Fall progresses, we think of the approaching Winter. We might also think of all the carbon that the once green leaves contain that will be released to the atmosphere as they decay.
The rapid expansion of palm oil plantations in the world’s tropical regions, particularly Indonesian Borneo, is becoming an increasingly significant source of global carbon emissions, a new study says.
Writing in the journal Nature Climate Change, researchers from Stanford and Yale universities project that the continued expansion of plantations will add more than 558 million metric tons of carbon dioxide
There is deep concern over air quality in China especially during the 2008 Olympics held there. Concern was raised over the air quality, and its potential effect on the athletes. Beijing committed then to remove 60,000 taxis and buses from the roads by the end of 2007 and relocate 200 local factories, including a prominent steel factory, China’s Olympian attempt
Columbia University scientists say that technologies to extract carbon dioxide from the air will likely become a critical part of any strategy to stabilize the global climate and should not be abandoned because of high costs.
Writing in the Proceedings of the National Academy of Sciences,
The European Union has introduced strict new auto emissions standards that officials say would cut carbon dioxide emissions by a third by 2020. The new standard, which must be approved by all member states and the European Parliament, would require that new passenger cars emit no more than 95 grams of carbon dioxide per kilometer driven,
The carbon cycle is a complex thing. There is carbon in the air (carbon dioxide), carbon in plants and animals, dissolved carbon in the sea and carbon in the soil that is constantly circulating to and from. Elevated levels of atmospheric carbon dioxide may accelerate carbon cycling and soil carbon loss in forests, as found in new research led by an Indiana University
For the first time in at least 800,000 years, atmospheric concentrations of carbon dioxide have crossed the threshold of 400 parts per million (ppm), with stations across the Arctic recording these record levels, the Associated Press reports.
Global concentrations have hit 395 ppm, but in
There are several ways to remove CO2 from a stack gas. None have reached a commercial basis yet due to the expense of the processing. The current method of removing the greenhouse gas carbon dioxide (CO2) from the flues of coal-fired power plants uses so much energy that no one bothers to use it. So says Roger Aines, principal investigator for a team that
At the Camp David meeting last week, G8 leaders agreed to act on climate change and air pollution by focusing on methane, black carbon (soot), and hydroflurocarbons (HFCs).
This is the logical follow up of a move in the same direction by the United States, China and other countries back to February. However, like the
U.S. scientists report that they have discovered new sources of methane percolating up from underground reservoirs as glaciers, ice caps, and permafrost melt in the Arctic.
University of Alaska researchers, conducting aerial and ground surveys, said they have discovered
The UK has re-launched a £1 billion ($1.6 billion) competition to promote the large-scale adoption of carbon-capture technology, an investment that government officials hope will make the UK a global leader in the emerging low-carbon energy sector.
Launched by the Department of Energy and Climate
With escalating shale oil production putting the US on track to become the world’s largest oil producer, investors are challenging an increasingly common industry practice – burning off or ‘flaring’ associated natural gas from shale oil wells – as environmentally damaging, economically wasteful and a threat to the industry’s bottom line.
