Stanford School of Engineering New study quantifies the degree of contribution to global climate caused by slash-and-burn agriculture and wildfires, and finds bigger than expected impact It has long been known that biomass burning – burning forests to create agricultural lands, burning savannah as a ritual , slash-and-burn agriculture and wildfires – figures into both climate change and public health. But until the release of a new study by Stanford University Civil and...

Japanese Nuclear Disaster Could Cause More Deaths
2012-07-18 11:17:41

Connie K. Ho for redOrbit.com — Your Universe Online Based on recent findings, researchers from Stanford University believe that radiation stemming from Japan´s Fukushima Daiichi nuclear disaster may eventually lead to anywhere from 15 to 1,3000 deaths, with 24 to 2,500 due to cancer, in the country. The results of the project differ from previous studies that stated that the radioactive release from the nuclear disaster would not lead to significant health effects. The...

Cities release more heat to the atmosphere than the rural vegetated areas around them, but how much influence these urban "heat islands" have on global warming has been a matter of debate. Now a study by Stanford researchers has quantified the contribution of the heat islands for the first time, showing that it is modest compared with what greenhouse gases contribute to global warming. "Between 2 and 4 percent of the gross global warming since the Industrial Revolution may be due to urban...

A new study of dust-like particles of soot in the air – now emerging as the second most important – but previously overlooked – factor in global warming provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported here today. In a presentation at the 242nd National Meeting & Exposition of the American Chemical Society...

If someone told you there was a way you could save 2.5 million to 3 million lives a year and simultaneously halt global warming, reduce air and water pollution and develop secure, reliable energy sources "“ nearly all with existing technology and at costs comparable with what we spend on energy today "“ why wouldn't you do it? According to a new study coauthored by Stanford researcher Mark Z. Jacobson, we could accomplish all that by converting the world to clean, renewable energy...

Soot from the burning of fossil fuels and solid biofuels contributes far more to global warming than has been thought, according to a new Stanford study.  But, unlike carbon dioxide, soot lingers only a few weeks in the atmosphere, so cutting emissions could have a significant and rapid impact on the climate. Controlling it may be the only option for saving the Arctic sea ice from melting. If soot emissions were eliminated, more than 1.5 million premature deaths from soot inhalation...

Everyone knows that carbon dioxide, the main greenhouse gas driving climate change, is a global problem. Now a Stanford study has shown it is also a local problem, hurting city dwellers' health much more than rural residents', because of the carbon dioxide "domes" that develop over urban areas. That finding, said researcher Mark Z. Jacobson, exposes a serious oversight in current cap-and-trade proposals for reducing emissions of heat-trapping gases, which make no distinction based on a...

Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand, say Stanford civil and environmental engineering Professor Mark Z. Jacobson and University of California-Davis researcher Mark Delucchi. To make clear the extent of those hurdles "“ and how they could be overcome "“...

The best ways to improve energy security, mitigate global warming and reduce the number of deaths caused by air pollution are blowing in the wind and rippling in the water, not growing on prairies or glowing inside nuclear power plants, says Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford.And "clean coal," which involves capturing carbon emissions and sequestering them in the earth, is not clean at all, he asserts.Jacobson has conducted the first quantitative,...

The winds that blow near the surface of the Earth have two beneficial effects: They provide a renewable source of clean energy and they evaporate water, helping rain clouds to build up. But aerosolized particles created from vehicle exhaust and other contaminants can accumulate in the atmosphere and reduce the speed of winds closer to the Earth's surface, which results in less wind power available for wind-turbine electricity and also in reduced precipitation, according to a study by Stanford...


Word of the Day
cruet
  • A vial or small glass bottle, especially one for holding vinegar, oil, etc.; a caster for liquids.
This word is Middle English in origin, and ultimately comes from the Old French, diminutive of 'crue,' flask.
