Saving For The Future, Seed By Seed, Seed Banks Helping Protect Rare And Endangered Pla... - 0 views

  • Many plants have been the source for medicine that cures disease. Take the rosy periwinkle, which is native to Madigascar. Before its properties were discovered, only 10 percent of children with leukemia lived. But from the plant, scientists created a compound that helped increase the survival rate. "With the compound, the rate has now gone up to 95 percent,” Raven says. “Who knows what else is out there in nature's pharmacy.”

  • "We will have 10 percent of the world’s seeds by 2010 and we would like to go on and have a quarter of the world’s species by 2020,” says Paul Smith, director of the Millennium Seed Bank Project.

Waste Home - Life-Cycle of Waste Image and Description | Climate Change - What You Can ... - 0 views

  • Landfilling, the most common waste management practice, results in the release of methane from the anaerobic decomposition of organic materials. Methane is 21 times more potent a GHG than carbon dioxide. However, landfill methane is also a source of energy, and some landfills capture and use it for energy. In addition, many materials in landfills do not decompose fully, and the carbon that remains is sequestered in the landfill and not released into the atmosphere.
  • The image above illustrates the four main stages of product life-cycles, all of which provide opportunities for GHG emissions and/or offsets. These stages are: raw material acquisition, manufacturing, recycling, and waste management.

  • Those who profess to favor freedom, and yet deprecate agitation, are those who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle. Power concedes nothing without a demand. It never did, and it never will.                                                                                                                         --Frederick Douglass 1857

  • Coal-to-Liquid is a Giant Leap Backwards UPDATE: On June 19th, the Senate rejected an amendment by Sen. Bunning that would have mandated a 6 billion gallon market by 2022 for liquid coal with a vote of 39-55. Also on June 19th, the Senate rejected an amendment led by Sen. Tester that would have provided $10 billion in loan guarantees for the development of liquid coal in a vote of 33-61.
  • In an editorial on June 14, the Washington Post called the coal-to-liquid movement a "sop to the coal industry that would pump more greenhouse gases into the atmosphere. That is not the way to go."

Despite lower carbon dioxide emissions, diesel cars may promote more global warming tha... - 0 views

  • The state of California is implementing an even more restrictive standard in 2004, allowing only 0.006 grams per kilometer [0.01 grams per mile] of particulate emissions.
  • Even if the California standard were introduced worldwide, says Jacobson, diesel cars may still warm the climate more than gasoline cars over 13 to 54 years.
  • Jacobson says that new particle traps being introduced by some European automobile manufacturers in their diesel cars appear to reduce black carbon emissions to 0.003 grams per kilometer [0.005 grams per mile], even below the California standard.
  • ...4 more annotations...
  • But, he says, "diesel vehicles emitting at this level may still warm the climate more than gasoline over a 10 to 50 year period, not only because of black carbon emissions, but also because the traps themselves require addition fuel use.
  • Gasoline/battery hybrid vehicles now available not only get better mileage than the newest diesels but also emit less black carbon."
  • In practice, less than 0.1 percent of light vehicles in the United States run on diesel fuel, whereas more than 25 percent do in Europe. (Almost a third of new European cars in 2000 were diesel powered.)
  • In both the United States and Europe, virtually all heavy trucks and buses are diesel powered, and American diesel consumption rates for all modes of ground transportation combined are about 75 to 80 percent of those in Europe.

US EPA - High GWP Gases: Science - 0 views

  • In addition to having high global warming potentials, SF6 and PFCs have extremely long atmospheric lifetimes, resulting in their essentially irreversible accumulation in the atmosphere once emitted (see below).
  • The definition of a GWP for a particular greenhouse gas is the ratio of heat trapped by one unit mass of the greenhouse gas to that of one unit mass of CO2 over a specified time period.
  • While the most current estimates for GWPs are listed in the IPCC's Third Assessment Report (TAR), EPA analyses use the 100-year GWPs listed in the IPCC's Second Assessment Report (SAR) to be consistent with the international standards under the United Nations Framework Convention on Climate Change (UNFCCC) (IPCC, 1996

  • Hydrofluorocarbons (HFCs) HFCs are man-made chemicals, many of which have been developed as alternatives to ozone-depleting substances (ODS) for industrial, commercial, and consumer products.
  • The global warming potentials of HFCs range from 140 (HFC-152a) to 11,700 (HFC-23).
  • The atmospheric lifetime for HFCs varies from just over a year for HFC-152a to 260 years for HFC-23.
  • Most of the commercially used HFCs have atmospheric lifetimes less than 15 years; e.g., HFC-134a, which i sused in automobile air conditioning and refrigeration, has an atmospheric life of 14 years.
  • Perfluorocarbons (PFCs) Primary aluminum production and semiconductor manufacture are the largest known man-made sources of two perfluorocarbons – CF4 (tetrafluoromethane) and C2F6 (hexafluoroethane).
  • The GWP of CF4 and C2F6 emissions is equivalent to approximately 6,500 and 9,200 tonnes, respectively. PFCs are also relatively minor substitutes for ozone-depleting substances (ODSs).
  • PFCs have extremely stable molecular structures and are largely immune to the chemical processes in the lower atmosphere that break down most atmospheric pollutants. Not until the PFCs reach the mesosphere, about 60 kilometers above Earth, do very high-energy ultraviolet rays from the sun destroy them. This removal mechanism is extremely slow and as a result PFCs accumulate in the atmosphere and remain there for several thousand years.
  • The estimated atmospheric lifetimes for CF4 and C2F6 are 50,000 and 10,000 years respectively.
  • Sulfur Hexafluoride (SF6) The global warming potential of SF6 is 23,900, making it the most potent greenhouse gas the IPCC has evaluated.
  • SF6 is used for insulation and current interruption in electric power transmission and distribution equipment, in the magnesium industry to protext molten magnesium from oxidation and potentially violent burning, in semiconductor manufacturing to create circuitry patterns on silicon wafers, and as a tracer gas for leak detection.
    • davido T
       
      semiconductors (i.e. electronics) not exactly clean-tech!
  • Like the other high GWP gases, there are very few sinks for SF6, so all man-made sources contribute directly to its accumulation in the atmosphere. Measurements of SF6 show that its global average concentration has increased by about 7% per year during the 1980s and 1990s, from less 1 ppt in 1980 to almost 4 ppt in the late 1990’s (IPCC, 2001).
  • HFC-134a has an atmospheric lifetime of about 14 years and its abundance is expected to continue to rise in line with its increasing use as a refrigerant around the world.
  • The only significant emissions of HFCs before 1990 were of the chemical HFC-23
    • davido T
       
      wow!! all since 1990
  • Between 1978 and 1995, HFC-23 concentrations have increased from 3 to 10 parts per trillion (ppt), and continue to rise. Since 1990, when it was almost undetectable, global average concentrations of HFC-134a have risen significantly to almost 10 ppt (parts per trillion).

    Un des piliers de l'Agenda 21, tel qu'il a été défini lors du Sommet de la Terre, à Rio, en 1992, est le principe de l'engagement et de la participation de tous les citoyens concernés par les actions entreprises. Ce principe a pour corollaire, la possibilité pour chacun d'avoir un accès à l'information se rapportant aux actions de l'Etat en vue d'un développement durable.
