The 2007 assessment report by the United Nations Intergovernmental Panel on Climate Change (IPCC) confirms that it is virtually certain that human activities (mainly through the use of fossil fuels and land development) have been responsible for the global warming that has taken place since the industrial revolution. Under current economic and social trends, the world is on a path to unprecedented ecological catastrophes. 1 As the IPCC report was being released, new evidence emerged suggesting that climate change is taking place at a much faster pace and the potential consequences are likely to be far more dreadful than is suggested by the IPCC report | more…
Most Americans today believe that the burning of fossil fuels is causing global warming, but not everybody agrees. Climate contrarians proclaim that global warming is not occurring at all, or that it is occurring but is entirely natural, i.e., that the anthropogenic (human) contribution to global warming is negligible. The contrarian ranks include the well-known radical journalist Alexander Cockburn, who forcefully proclaimed anthropogenic global warming to be a myth in three articles published in 2007 on the CounterPunch Web site and in The Nation | more…
The world ocean covers approximately 70 percent of the earth. It has been an integral part of human history, providing food and ecological services. Yet conservation efforts and concerns with environmental degradation have mostly focused on terrestrial issues. Marine scientists and oceanographers have recently made remarkable discoveries in regard to the intricacies of marine food webs and the richness of oceanic biodiversity. However, the excitement over these discoveries is dampened due to an awareness of the rapidly accelerating threat to the biological integrity of marine ecosystems | more…
For several decades following 1947, the modern large dam in India presented itself as a political conundrum, often voiced in strange, contradictory tones. In an oft-quoted speech in July 1954 Jawaharlal Nehru, India’s first prime minister (1947–64), likened the large dam to a “modern temple.” Later, in a less remembered speech before a gathering of engineers and technocrats in 1958, Nehru, as if in contrition, bemoaned the quest for big dams as a “disease of gigantism | more…
The three water crises—dwindling freshwater supplies, inequitable access to water, and the corporate control of water—pose the greatest threat of our time to the planet and to our survival. Together with impending climate change from fossil fuel emissions, the water crises impose some life-or-death decisions on us all. Unless we collectively change our behavior, we are heading toward a world of deepening conflict and potential wars over the dwindling supplies of freshwater— between nations, between rich and poor, between the public and the private interest, between rural and urban populations, and between the competing needs of the natural world and industrialized humans | more…
An acute food crisis has struck the world in 2008. This is on top of a longer-term crisis of agriculture and food that has already left billions hungry and malnourished. In order to understand the full, dire implications of what is happening today it is necessary to look at the interaction between these short-term and long-term crises. Both crises arise primarily from the for-profit production of food, fiber, and now biofuels, and the rift between food and people that this inevitably generates… | more…
Twenty years ago climatologist James Hansen of NASA’s Goddard Institute of Space Studies, widely considered to be the world’s leading authority on global warming, first brought the issue into the public spotlight in testimony before the U.S. Congress. Recently, Hansen published an article entitled “Climate Catastrophe” in the New Scientist (July 28, 2007), http://www.newscientist.com. There he presented evidence suggesting that under “business as usual,” in which greenhouse gas emissions continue to increase unchecked, a rise in sea level by several meters during the present century due to the melting of polar ice sheets is a “near certainty.” | more…
Rachel Carson was born just over 100 years ago in 1907. Her most famous book Silent Spring, published in 1962, is often seen as marking the birth of the modern environmental movement. Although an immense amount has been written about Carson and her work, the fact that she was objectively a “woman of the left” has often been downplayed. Today the rapidly accelerating planetary ecological crisis, which she more than anyone else alerted us to, calls for an exploration of the full critical nature of her thought and its relation to the larger revolt within science with which she was associated. | more…
Regardless of how attractive it may seem or how hard the Bush administration promotes the interests of his nuclear power industry supporters, electricity from nuclear fission is still so hampered by the problem of high-level waste disposal, that any building of new plants would be a serious mistake.…Recent technical advances are still grossly inadequate, and the future of nuclear power, as we know it, is very poor at best. | more…
Considerations of Environmental Protection Criteria for Radioactive Waste, U.S. Environmental Protection Agency, Office of Radiation Programs, Waste Environmental Standards Program, Washington, D.C. 20460, February 1978.
Most government reports make dull reading, and this one is no exception. But it contains a message which needs to be taken in by everyone even minimally concerned about the future of the human race. That message, quite simply, is that there is not and cannot be a safe program for disposing of radioactive wastes. The reasons are basically simple, do not depend on any complicated scientific arguments, and cannot be refuted or made irrelevant by any conceivable increase in scientific knowledge or technological capability. They can be summed up in a series of quotations from the report. | more…
When I was a boy I always assumed that I would grow up to be both a scientist and a Red. Rather than face a problem of combining activism and scholarship, I would have had a very difficult time trying to separate them. | more…
Isador Nabi is widely believed to have emerged from the swamps of southern Vermont some time in the 1970s. The first written record of him was a short-lived biography in American Men of Science. Then he seems to have dissolved. But it is said that he is a sort of academic Golem and that whenever greed, obscurantism, careerism, reductionism, and opportunism afflict science, that is, most of the time, he condenses again out of hypothetico-deductive dust in some obscure vault in that library where they bury unread dissertations, and he lurks in and around academia spending his rage in jest. An unsuccessful obituary appeared in Nature in 1981. Since then he has been nominated (by himself) eleven times for the Grammy and his works have been retranslated into English from 116 foreign languages that didn’t want them. | more…
