NASA Study Finds Connection Between Population And Pollution
2013-08-20 14:33:41

Brett Smith for redOrbit.com - Your Universe Online While previous research has linked employment or innovation statistics to urban population density, a new study from NASA scientists has made a connection between pollution and the number of people living in a city. Using satellite observations, the NASA team was able to calculate air pollution's dependence on population for cities in the United States, Europe, China and India. According to the report, which was published in the...

The past decade has witnessed a significant growth in Asian air pollution, causing a great concern for air quality and climate. If government policy makers hope to contain the problem, they will need increased research and better computer models of black carbon and other aerosol pollutants, also known as atmospheric brown cloud (ABC), according to University of Iowa engineering professor Gregory Carmichael. Carmichael made the case for more research and better-informed policy makers when...

GREENBELT, Md., Dec. 14 /PRNewswire-USNewswire/ -- A NASA-led study has found new evidence that a "heat pump" effect, driven by emissions of soot, or black carbon, contributes as much (or more) to atmospheric warming in the Himalayas as greenhouse gases. This warming fuels the melting of glaciers and could threaten fresh water resources in a region that is home to more than a billion people.

Air pollution in eastern China during the last 50 years has led to a reduction in the amount of light rainfall of almost a quarter. This is revealed by an international study conducted with support from the University of Gothenburg, Sweden. There is a risk that the consequences will be increased drought, reduced harvests and poorer public health.China's dramatic growth has also brought about an increase in environmental problems. At the same time as the population has more than doubled during...

Swedish and Indian researchers constrain the sources of climate- and health-afflicting soot pollution over South Asia A gigantic brownish haze from various burning and combustion processes is blanketing India and surrounding land and oceans during the winter season. This soot-laden Brown Cloud is affecting South Asian climate as much or more than carbon dioxide and cause premature deaths of 100 000s annually, yet its sources have been poorly understood. In this week's issue of Science...

Thick smog clouds that loom over Asia threaten the livelihood of crops and contain particles that actually reflect the sun's rays away from the earth, the U.N. reported on Thursday. These so-called "atmospheric brown clouds" are primarily caused by the burning of fossil fuels and firewood. They can be more than one mile thick and result in changing weather patterns in areas across Asia, the Middle East, southern Africa and the Amazon Basin. First identified by the report's lead researcher in...

Thick smog clouds that loom over Asia threaten the livelihood of crops and contain particles that actually reflect the sun's rays away from the earth, the United Nations reported on Thursday. "One of the impacts of this atmospheric brown cloud has been to mask the true nature of global warming on our planet," United Nations Environment Program (UNEP) head Achim Steiner said at the launch in Beijing of a new report on the phenomenon. Caused by the burning of fossil fuels, wood and plants,...

A study found an increasing pollution problem in Asia could affect cloud formation high in the Himalayas, an action that could make problems for monsoons and speed the melting of glaciers. Researchers in France and Italy, studied microscopic particles in the air that could be seeds for water droplets at the highest mountain observatory in the world located in Nepal. Scientists say it was the first time they observed such particles forming so high, far above those seen in previous studies...
