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.

  • 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.

  • Despite the US government’s opposition to the Kyoto Protocol, California, New York and New Jersey embraced carbon trading Tuesday as they joined European governments, Canadian provinces, and New Zealand to launch a forum known as the International Carbon Action Partnership.

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.

The Thirteenth Tipping Point | Mother Jones - 0 views

  • The 12 tipping points are: 1. Amazon Rainforest 2. North Atlantic Current 3. Greenland Ice Sheet 4. Ozone Hole 5. Antarctic Circumpolar Current 6. Sahara Desert 7. Tibetan Plateau 8. Asian Monsoon 9. Methane Clathrates 10. Salinity Valves 11. El Nino 12. West Antarctic Ice Sheet
  • A 2005 study by Anthony Leiserowitz, published in Risk Analysis, found that while most Americans are moderately concerned about global warming, the majority—68 percent—believe the greatest threats are to people far away or to nonhuman nature. Only 13 percent perceive any real risk to themselves, their families, or their communities. As Leiserowitz points out, this perception is critical, since Americans constitute only 5 percent of the global population yet produce nearly 25 percent of the global carbon dioxide emissions.
  • 12 ASTEROIDS AND EVOLVING INTO WISDOM IN 2004, JOHN SCHELLNHUBER, distinguished science adviser at the Tyndall Centre for Climate Change Research in the United Kingdom, identified 12 global-warming tipping points, any one of which, if triggered, will likely initiate sudden, catastrophic changes across the planet. Odds are you've never heard of most of these tipping points, even though your entire genetic legacy—your children, your grandchildren, and beyond—may survive or not depending on their status.

  • EISEROWITZ'S STUDY OF risk perception found that Americans fall into "interpretive communities"—cliques, if you will, sharing similar demographics, risk perceptions, and worldviews.

      that's a great term "interpretive communities"

  • On one end of this spectrum are the naysayers: those who perceive climate change as a very low or nonexistent danger. Leiserowitz found naysayers to be "predominantly white, male, Republican, politically conservative, holding pro-individualism, pro-hierarchism, and anti-egalitarian worldviews, anti-environmental attitudes, distrustful of most institutions, highly religious, and to rely on radio as their main source of news."
  • This group presented five rationales for rejecting danger: belief that global warming is natural; belief that it's media/environmentalist hype; distrust of science; flat denial; and conspiracy theories, including the belief that researchers create data to ensure job security
  • We might wonder how these naysayers, who represent only 7 percent of Americans yet control much of our government, got to be the way they are. A study of urban American adults by Nancy Wells and Kristi Lekies of Cornell University sheds some light on environmental attitudes. Wells and Lekies found that children who play unsupervised in the wild before the age of 11 develop strong environmental ethics. Children exposed only to structured hierarchical play in the wild—through, for example, Boy Scouts and Girl Scouts, or by hunting or fishing alongside supervising adults—do not. To interact humbly with nature we need to be free and undomesticated in it. Otherwise, we succumb to hubris in maturity. The fact that few children enjoy free rein outdoors anymore bodes poorly for our future decision-makers.

      hmm... was it so clear-cut a conclusion?
  • THE ALARMISTS AND THE ACROBAT ON THE OTHER END of Leiserowitz's spectrum of perception regarding global warming is an interpretive community he calls the alarmists, generally comprised of individuals holding pro-egalitarian, anti-individualist, and antihierarchical worldviews, who are supportive of government policies to mitigate climate change, even so far as raising taxes. Members of this group are likely to have taken personal action to reduce greenhouse gas emissions.
  • Collectively, alarmists compose 11 percent of Americans, with the remaining interpretive communities falling considerably closer to the alarmists than the naysayers in the spectrum—suggesting the gap might be cinched by sustained public education on the neighborhood dangers likely to arise in a changed global climate.
  • Hurricane Katrina provided a wake-up call for how bad it can get in the neighborhood, and may prove a tipping point itself.
  • Yet long before its rampage, American kids were coloring pictures of the first icon of global environmentalism, the Amazon. Its billion-plus acres of rivers and rainforest—its trees collecting and containing excessive greenhouse gases from the atmosphere—were our primer for the revolutionary notion that the earth's neighborhoods are interdependent. Today Amazonia is the most famous of Schellnhuber's tipping points. For a generation, kids have grown up learning that the Amazon is at risk from massive deforestation. But even if clearcutting were to halt, climate models forecast that a warming globe will convert the wet Amazonia forest into savanna within this century, and the loss of trees will render the region a net CO2 producer, further accelerating global warming.

  • Also, every gallon of gasoline or diesel fuel burned releases about 22 pounds of carbon dioxide (CO2), the major pollutant causing global warming.

      how is that possible when a gallon of gas doesn't even weigh 22 lbs??
