GLOBAL WARMING AND WHAT CAN BE DONE ABOUT IT
Steve Sachs, Coordinating Editor. Nonviolent Change
From what I have gleaned from teaching environmental and energy policy some years ago, and following developments in environmental research since, it is my understanding that global warming is part of a complex interactive ecological system in which human action, particularly resource use, have a large impact. There is now almost complete scientific agreement that global warming, bringing horrendous climate change, that is already having serious impacts on human life around the planet, is primarily caused by human activity, causing carbon dioxide, methane and other green house gasses to enter the atmosphere, that then trap heat. The relevant direct human action is first the burning of fuels (and other burning) that result in the release of green house gasses, but such gasses are also directly put into the atmosphere by other human acts; and secondarily as a result of the warming that has been occurring because of people increasing green house gas levels in the atmosphere (such as the melting of permafrost in the Arctic releasing huge amounts of carbon dioxide, and 14 times more heat increasing methane, and the heating of the oceans which reduces their capacity to absorb green house and other gasses – directly, and from the reduction, which occurs with raising sea water temperatures, of ocean plant life that transforms huge amount of carbon dioxide into oxygen and carbon).
Global warming is also increased by human action, such as deforestation, that kills trees and other green plants that convert carbon dioxide into oxygen and carbon (used by the plants). Thus global warming can be reduced in several ways: 1) by reduction in the burning of green house gas producing fuels, by increasing fuel use efficiency, reducing fuel burning, and switching to non-green house gas producing sources of energy, including wind power, photovoltaic cells and other direct solar power, wave action, hydro electric power, ocean temperature differential power, atomic energy (which may be to dangerous to use because of possible meltdowns, and the problem of dealing with highly radioactive waste that remains dangerous for as long as 1000,000 years), geothermal energy, using hydrogen and possibly other non-green house gas producing fuels, using as fuels green house gases that would enter the atmosphere without producing energy for human endeavor, if not captured and burned (e.g. capturing and burning methane escaping from landfills), and capturing carbon produced by green house gas producing fuel use; 2) by increasing the number of trees (ending deforestation, and reforesting) and other carbon dioxide transforming plants. 3) increasing the amount of particulate matter in the atmosphere, which blocks incoming sun light, and has a cooling effect. This, however, almost always has major detrimental side effects for human beings, including causing major health problems (to consider only the simplest of the many aspects of putting dust into the air).
As this last method of reducing global warming suggests, there is much more to the ecological problem facing human beings. Human activity causes a great many other impacts on the environment, some of which tend to change the ecological system of the planets, and/or its local and regional subsystems, often negatively from a human perspective, and which in many cases have direct negative effects for human beings, including the production of a wide range of pollutants from simple dust, to toxic chemicals, radiation, and biological hazards. So while global warming is often considered the most obvious current environmental threat for humanity (though some would say that radiation from bombs, accidents and nuclear waste is a greater danger, or that human caused or spread disease is a greater threat), global warming cannot properly be looked at in isolation. It has to be considered as part of a larger set of relationships among human beings (physical, social, economic, political. Etc,) and considering human beings as part of the Earth’s environmental system and subsystems. Indeed, in that context, global warming is only one of the negative side effects of human activity that needs to be considered. For example, destruction of the ozone layer (leading to toxic levels, for many – and at some point virtually all – forms of life) of ultra violate radiation penetrating the atmosphere, as the result of the use of certain chemicals that escape upward and destroy the ozone layer of the upper atmosphere, is again increasing because of the increased use in some developing counties of refrigerants and propellants, whose use has been greatly reduced in the rest of the world.
One aspect of the global warming problem in particular, and of environmental protection generally, is resource use: the finding, processing, transporting, using of resources, and disposing of residual material in that whole process, including all the results (positive, negative and neutral), direct and indirect, of that activity. In the case of energy, the most used source world wide, oil, is approaching the point where demand overwhelms supply, largely because of the huge and growing increases in oil consumption by China and other developing nations. Compounded with interruptions and uncertainties about some major oil production, because of war and political instability, this has spurred the development of biofuel, particularly ethanol, most notably in Brazil and the U.S. While increasing ethanol production has economic, political and security advantages, ethanol production currently increases global warming, and other polluting, because its production requires significantly more energy than does gasoline and other oil product production. (That may change as more effort, money and energy is required to mine oil, whether in pumping steam into no longer free flowing oil wells, or in mining oil from shale and tar sands). Also, despite what some advertising claims, burning ethanol simply produces a different combination of pollutants than does burning gasoline. While it might make sense to have some increase in ethanol use as a bridge to develop non greenhouse gas producing energy, and to include economic and human concerns properly in the process of energy transformation, to overcome global warming and reduce dangerous pollution more generally, it is far better to emphasize non-greenhouse gas producing sources of energy (taking into account the pollution, including greenhouse gas production, and cost of such development – e.g. manufacture of photo voltaic cells is not entirely clean). The politics and public relations of powerful established economic interests, in many cases, resists changes that are beneficial to whole societies and the population of the planet. And that resistance must be overcome, and where possible transformed (as has been happening, as even some oil companies have been moving to “greener” business practices).
One of the ways of reducing green house gas emition, and major pollution, as well as scarce resource use, is to reduce automobile use, which is one of the major and fastest growing sources of pollution, including greenhouse gases. Increasing public transportation, including high speed trains between cities, will help this, and incentives and encouragement to use such transportation will further help (reduced fares, etc.). A problem in the U.S. is that automotive and truck use is governmentally subsidized, while rail roads are not. Increasing automobile efficiency, introducing electric and highbred vehicles – which can be supported by subsidies and other incentives, while penalizing (e.g. taxes) greenhouse gas producing emitions, especially by highly innefficient engines. Encouraging, rewarding use of bicycles and walking can also reduce vehicle use. Careful urban, land use and traffic planning by governments, business and NGOs can also be a major vehicle for reducing vehicle use, and resulting pollution.
Production of power for electricity, manufacturing, etc., can also be switched from higher to lower polluting – particularly of greenhouse gases – while machines, devices, equipment, appliances, etc. can be made more energy efficient, and such use encopuraged/subsidiesed/advertised. Providing public information about the problem and what people can do about it, with specific information about helpful products and actions, can be a major help in all aspects of dealing with environmental-human protection.
A major aspect of reducing greenhouse gas emition and other pollution and environmental degradation is the development of new and improvement of old technology, methods, energy sources, etc. A great deal of investment needs to be made in this area (and some of that is happening) with the support of public and private funding.
Almost all of the aspects of the problem can be better met with increased intra and inter organization, and interpersonal, collaboration and efficiency. Government and private organizations and persons can play an important facilitating and communicating roll here (such as planning locations of facilities for shorter trvavel/shipping, coordination of research, sharing of information, timing of work shifts to avoid traffic jams, etc).
A critical aspect of protecting human life, economy, health, etc. by protecting the environment is in a variety of public policies at every level of government, from direct regulation (which should be smart regulation - as set out in Reinventing Government), subsidies, encouragements, penalties, planning, voluntary planning – encouraging collaboration/coordination, smart seeding of research and production of better products (e.g. the government ordering large numbers of a better product to bring the price down), spreading information, encouraging environmentally friendly activity, etc. To achieve this requires political action, including public expression (hence the need of public and private public education), by individuals, groups, corporations, and government entities.
Green business policies and actions are also an extremely important aspect of meeting environmental threats, including global warming. Government policy can encourage this, as must public caring about the issues and demand for green business activity. Education of business leaders and personnel is also critical. Understanding that moving in a greener direction can create jobs (some very well respected analysis shows clearly that moving to protect the environment will produce far more jobs and business opportunities than it creates, though some vested interests do, and will continue to, resist that proposition). Already quite a number of firms, and in some areas chambers of commerce, see that their future is dependent on protecting the environment, while others now want to seem that they are acting in a green way (investigative reporting and environmental group research needs to expose false green claims, encouraging real green action). Professional organizations can play an important part by developing, publicizing, encouraging, and at times enforcing a green ethic.
These are a few of the many interrelated aspects, briefly presented, of meeting the massive environmental threat we human beings are bringing down on ourselves. In proceeding to take protective action, it is important to see that all the aspects of the problems involved are interrelated, and to analyze them and act upon them holistically, and so far as possible (with out co-opting oneself) work collaboratively.
