Greenhouse Gasses Hit Record High
2012-11-20 12:15:43

Brett Smith for redOrbit.com - Your Universe Online Greenhouse gas levels, which are capable of driving global warming over the coming decades, reached new highs in 2011, according to a new report by the World Meteorological Organization (WMO), a United Nations agency. The volume of carbon dioxide grew by two parts per million (ppm) to reach 390.9 ppm, about 40 percent above the pre-industrial level, the survey said. The survey added that the levels of two other greenhouse gases,...

Mine waste has greenhouse gas-trapping potential that should be economically valued says researcher It's time to economically value the greenhouse gas-trapping potential of mine waste and start making money from it, says mining engineer and geologist Michael Hitch of the University of British Columbia (UBC). Hitch studies the value of mine waste rock for its CO2-sequestration potential, or "SP." He says mining companies across Canada will, in future, be able to offset CO2 emissions with...

Global Warming Could Prevent Next Ice Age
2012-11-09 10:30:13

April Flowers for redOrbit.com — Your Universe Online We hear reports every day about the dangers and evils of carbon emissions, but could there be a good side? A research team at the University of Gothenburg thinks so. Their new study, published in Mires and Peat, suggests that mankind's emissions of fossil carbon, and the temperature rise that accompanies it, could prove to be our salvation from the next ice age. The current increase in peatland extent could reverse this effect,...

Methane Consuming Microorganisms Have Strange Diet
2012-11-06 13:06:13

Max-Planck-Gesellschaft Methane supplies the energy for cell metabolism, but is not the carbon source Methane is formed under the absence of oxygen by natural biological and physical processes, e.g. in the sea floor. It is a much more powerful greenhouse gas than carbon dioxide. Thanks to the activity of microorganisms this gas is inactivated before it reaches the atmosphere and unfolds its harmful effects on Earth's climate. Researchers from Bremen have now proven that these...

Climate change and extreme weather events grab the headlines, but there is another, lesser known, global change underway on land, in the seas, and in the air: acidification. It turns out that combustion of fossil fuels, smelting of ores, mining of coal and metal ores, and application of nitrogen fertilizer to soils are all driving down the pH of the air, water, and the soil at rates far faster than Earth's natural systems can buffer, posing threats to both land and sea life. "It's a...

Halving the amount of nitrogen fertilizer used in certain areas of China would substantially decrease greenhouse gas emissions without affecting crop productivity and the area's natural carbon sink. This is according to a new study, published today, 1 November, in IOP Publishing's Environmental Research Letters, which showed that a 60 per cent reduction in fertilizer use would significantly reduce emissions from areas that are, anyway, "over-fertilized", such as the North China Plain and...

Global Warming And Rice Production
2012-10-23 06:34:24

April Flowers for redOrbit.com - Your Universe Online A new study led by the University of California, Davis finds that more carbon dioxide in the atmosphere, coupled with rising temperatures, is making rice agriculture a larger source of the potent greenhouse gas methane. Relatively simple changes in rice cultivation, according to the study, could help reduce methane emissions. "Together, higher carbon dioxide concentrations and warmer temperatures predicted for the end of this...

Glaciers Cracking In Presence Of Carbon Dioxide
2012-10-11 19:48:46

Alan McStravick for redOrbit.com — Your Universe Online Our glaciers and ice caps are experiencing a little chemistry-based “good cop, bad cop” and it looks like the bad cop is going to make them crack under pressure. There is little doubt in the scientific community about the excessive presence at startling levels of carbon dioxide (CO2) in our atmosphere and the effect it is having on our increasing global temperatures and our melting ice caps and glaciers....

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
