Climate change scientist Michael Mann discusses the most significant findings in the second installment of the IPCC report and how some climate change deniers are already attempting to discredit its conclusions
Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels. By using a worldwide agricultural model to estimate emissions from land-use change, we found that corn-based ethanol, instead of producing a 20% savings, nearly doubles greenhouse emissions over 30 years and increases greenhouse gases for 167 years. Biofuels from switchgrass, if grown on U.S. corn lands, increase emissions by 50%. This result raises concerns about large biofuel mandates and highlights the value of using waste products.
Mr. Jean Ziegler, the former United Nations Special Rapporteur on the Right to Food, repeatedly denounced biofuels as “a crime against humanity.” Biofuels have raised the cost of fertilizer, farmland, and food all over the world, resulting in the deaths of millions of innocent people. Biofuels are a fraud because they are sold as being “green.” In provable fact, biofuels have increased greenhouse gas release, water pollution and water shortages, deforestation, and topsoil erosion.
Biofuels are terribly energy inefficient and will never help us gain “energy independence” as our politicians promise. It takes so much fossil fuel energy to produce biofuels, and they do so much harm, that they are just not worth the effort. Biofuels are a money making scam and a crime against all of us, not a reasonable solution to any of our many problems.
Even if we used “every piece of wood on the planet, every piece of grass eaten by livestock, and all food crops, that much biomass could only provide about 30 percent of the world’s total energy needs.” – Dr. Timothy Searchinger, Princeton University
Our leaders seem to care more about the profits of ethanol manufacturers and the corporate farm lobby than they do about protecting the affordability and long term survivability of the human food supply. Food has become so expensive now that more and more Americans need food stamps just to survive. Please write your representatives in Congress and ask them why they wish to continue drilling for energy in the human food supply.

THE RENEWABLE ENERGY DISASTER

Global food prices have risen because food grains are in short supply. Another strong reason given for this is the shift to biofuel, which are promoted as a green alternative to conventional fuels, like petrol and diesel. The use of food for fuel started when the energy crisis forced the world to look for alternatives. Scientists turned to biofuel for energy solutions.
(November 1, 2007) President Bush promised to expand American biofuel production, but the result has been worse than nothing. Corn is a poor source for energy, but growing it and other staples as fuel has caused food prices worldwide to explode – even as the scarcity of flex-fuel vehicles means no significant increase in U.S. biofuel use.
Now the U.N. is worried about rising food costs, while environmentalists see entire regions torn up to grow fuel crops. The great ethanol boom of 2007 goes bust, this week on Global Pulse.

Biofuel was the buzzword of the millenniums Green Revolution- an eco-friendly blend of plant oil with regular oil, which could run your car and produce electricity. Now the global demand for Biofuel is threatening the lives of the 45 million people who depend on the rainforest for food. A riveting look at the food vs fuel debate.
Lawrence-Berkeley Lab scientist and energy expert David Fridley talks about the reality of biofuels as an alternative energy fuel. He explains inherent cost and production problems with ethanol and similar biofuels.
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
