Climate Change

In 2000, recycling resulted in an annual energy savings of at least 660 trillion BTUs, which equals the amount of energy used in 6 million households annually. In 2005, recycling is conservatively projected to save 900 trillion BTUs, equal to the annual energy use of 9 million households.

What effects do waste prevention and recycling have on global warming?

What materials are most commonly recycled in the United States through collection programs? US recycling rates for commonly recycled consumer goods in 2006 are listed below: Newspapers: 87.9% Corrugated Cardboard Boxes: 72.0% Steel Cans: 62.9% Yard Trimmings: 62.0% Aluminum Beer and Soft Drink Cans: 45.1% Magazines: 40.5% Tires: 34.9% Plastic HDPE Milk and Water Bottles: 31.0% Plastic Soft Drink Bottles: 30.9% Glass Containers: 25.3% EPA's annually updated report, Municipal Solid Waste in the US: 2006 Facts and Figures, describes the national MSW stream based on data collected since 1960. The historical perspective provided is useful for establishing trends in the types of MSW generated and the ways in which it is managed.

The Second City's green-roofs program is second to none, with more than 2.5 million square feet devoted to providing cooling and insulating cover.

The first major city to tackle global warming, Portland creates less greenhouse gases than it did 15 years ago, while saving $2 million annually on city energy bills--and attracting new business with its efficiency expertise.

What is happening here is a vision that many in rural America see as their salvation: high-performance moonshine from amber fields of grain, and a “grass station” in every town. It may be a chimera. It may drain precious water from the arid plains and produce less energy that it uses. But it has the undeniable power of an idea in ascendancy.

The vision of a decentralized ethanol industry is taking shape, albeit an industry aided by tax breaks and government mandates. There are now 113 American ethanol plants and an additional 77 under construction, according to the Renewable Fuels Association, the industry trade group. Most of them are right in the middle of the Farm Belt, in counties that have been losing people since the Depression.

Archer Daniels Midland, once the dominant force, is less of a player, controlling about 22 percent of the market. But roughly 40 percent of the new biorefineries are locally owned, representing the sweat and capital of farmers, retired schoolteachers and small-town bankers.

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

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.

Governor to sign global-warming bill Why Sept. 27, 2006 will be a day to remember Daniel M. Kammen

More important than the target, which is itself dramatic, is the fact that California will establish emission controls on the largest industrial sectors, including utilities, oil refineries and cement manufacturing, and will use market mechanisms -- emissions trading -- to find the economically most-efficient ways to reduce global warming.

AB32, introduced by Assemblywoman Fran Pavley, D-Agoura Hills, and Assembly Speaker Fabian Núñez, D-Los Angeles, calls for a cap on greenhouse-gas emissions statewide, and a 25 percent reduction by 2020.

Call it the networked environment. Picture tiny - we're talking small as a dime - wireless sensors lining lake beds and ocean floors, buried in the ground, and floating in the sky. All the time they are sniffing the air, water, and soil for pollutants and detecting changes in temperature and pressure.

The payoff: real-time data on a variety of phenomena that affect the economy and society - climate change, hurricanes, air and water pollution.
