Crisis

How bad is the environmental crisis?  You have all heard about the dangers of climate change due to the emission of carbon dioxide and other greenhouse gases into the atmosphere -- trapping more heat on earth.  You are undoubtedly aware that global warming threatens the very future of the humanity, along with the existence of innumerable other species.  Indeed, James Hansen, the leading climatologist in this country, has gone so far as to say this may be "our last chance to save humanity."

But climate change is only part of the overall environmental problem.  Scientists, led by the Stockholm Resilience Centre, have recently indicated that we have crossed, or are near to crossing, nine "planetary boundaries" (defined in terms of sustaining the environmental conditions of the Holocene epoch in which civilization developed over the last 12,000 years): climate change, species extinction, the disruption of the nitrogen-phosphorus cycles, ocean acidification, ozone depletion, freshwater usage, land cover change, (less certainly) aerosol loading, and chemical use.  Each of these rifts in planetary boundaries constitutes an actual or potential global ecological catastrophe.  Indeed, in three cases -- climate change, species extinction, and the disruption of the nitrogen cycle -- we have already crossed planetary boundaries and are currently experiencing catastrophic effects.  We are now in the period of what scientists call the "sixth extinction," the greatest mass extinction in 65 million years, since the time of the dinosaurs; only this time the mass extinction arises from the actions of one particular species -- human beings.  Our disruption of the nitrogen cycle is a major factor in the growth of dead zones in coastal waters.  Ocean acidification is often called the "evil twin" of climate change, since it too arises from carbon dioxide emissions, and by negatively impacting the oceans it threatens planetary disruption on an equal (perhaps even greater) scale.  The decreased availability of freshwater globally is emerging as an environmental crisis of horrendous proportions. All of this may seem completely overwhelming.  How are we to cope with all of these global ecological crises/catastrophes, threatening us at every turn?  Here it is important to grasp that all of these rifts in the planetary system derive from processes associated with our global production system, namely capitalism.  If we are prepared to carry out a radical transformation of our system of production -- to move away from "business as usual" -- then there is still time to turn things around; though the remaining time in which to act is rapidly running out.

Let's talk about climate change, remembering that this is only one part of the global environmental crisis, though certainly the most urgent at present.  Climate science currently suggests that if we burn only half of the world's proven, economically accessible reserves of oil, gas, and coal, the resulting carbon emissions will almost certainly raise global temperatures by 2° C (3.6° F), bringing us to what is increasingly regarded as an irreversible tipping point -- after which it appears impossible to return to the preindustrial (Holocene) climate that nourished human civilization.  At that point various irrevocable changes (such as the melting of Arctic sea ice and the ice sheets of Greenland and Antarctica, and the release of methane from the tundra) will become unstoppable.  This will speed up climate change, while also accelerating vast, catastrophic effects, such as rising sea levels and extreme weather.  Alternatively, if our object is the rational one of keeping warming below 2° C, climate science now suggests that we should refrain from burning more than a quarter of the proven, economically exploitable fossil fuel reserves (unconventional sources such as tar sands are excluded from this calculation).

The central issue in all of this, it is important to understand, is irreversibility.  Current climate models indicate that if we were to cease burning fossil fuels completely at the point that global average temperature had increased by 2°C, or 450 parts per million (ppm) carbon concentration in the atmosphere (the current level is 390 ppm), the earth would still not be close to returning to a Holocene state by the year 3000.  In other words, once this boundary is reached, climate change is irreversible over conceivable human-time frames.  Moreover, the damage would be done; all sorts of catastrophic results would have emerged. Recently climate scientists, writing for Nature magazine, one of the world's top science publications, have developed a concrete way of understanding the planetary boundary where climate change is concerned, focusing on the cumulative carbon emissions budget.  This is represented by the trillionth ton of carbon.  So far more than 500 billion tons of carbon have been emitted into the atmosphere since the industrial revolution.  In order to have an approximately even chance (50-50) of limiting the increase in global average temperature to 2°C, the cumulative CO2 emissions over the period 1750-2050 must not exceed one trillion tons of carbon; while in order to have a 75 percent chance of global warming remaining below 2°C, it is necessary not to exceed 750 billion tons of carbon.  Yet, according to present trends, the 750 billionth ton of carbon will be emitted in 2028, i.e., about sixteen years from now. If we are to avoid burning the 750 billionth ton of carbon over the next four decades, carbon dioxide emissions must fall at a rate of 5 percent per year; while to avoid emitting the trillion ton, emissions must drop at a rate of 2.4 percent a year.  The longer we wait the more rapid the decrease that will be necessary.  The trillionth ton, viewed as the point of no return, is the equivalent of cutting down the last palm tree on Easter Island.  After that it is essentially out of our hands.

This takes us to the social question.  The problem we face when it comes to the appropriate response to impending climate catastrophe is not so much one of climate science -- beyond understanding the environmental parameters in which we must act -- as social science.  It is an issue of social conditions and social agency.  We live in in a capitalist society, which means a society in which the accumulation of capital, i.e., economic growth carried out primarily on the terms of the 1 percent at the top (the ruling capitalist class), is the dominant tendency.  It is a system that accumulates capital in one phase simply so that it can accumulate still more capital in the next phase -- always on a larger scale.  There is no braking mechanism in such a system and no social entity in control.  If for some reason the system slows down (as it is forced to periodically due to its own internal contradictions) it enters an economic crisis.  That may be good temporarily for the environment, but it is terrible for human beings, particularly the bottom portion of the 99 percent, faced with rising unemployment and declining income. Overall, capitalism is aimed at exponential growth.  It cannot stand still.  The minimum adequate growth rate of the system is usually thought to be 3 percent.  But this means that the economy doubles in size about every 24 years.  How many such doublings of world output can the planet take? Hence, there is a direct and growing contradiction between capitalism and the environment, a contradiction that becomes more and more apparent as the size of the capitalist economy begins to rival the basic biogeochemical processes of the planet.  Naomi Klein has rightly characterized the age we live in as "disaster capitalism" because of its dual economic and ecological crises -- and due to the increasingly exploitative means the rich employ to enable them to prosper in the midst of increasing destruction.

There are two predominant ways of addressing the climate crisis and the environmental problem generally.  One is to look for technological ways out -- often seen as being spurred by the creation of carbon markets, but the onus is on the technology.  The argument here is that through the massive introduction of various advanced technologies we can have our pie and eat it too.  We can get around the environmental problem, it is suggested, without making any fundamental social changes.  Thus, the pursuit of profits and accumulation can go on as before without alteration.  Such magic-technological answers are commonly viewed as the only politically feasible ones, since they are attractive to corporate and political-power elites, who refuse to accept the need for system change.  Consequently, the establishment has gambled on some combination of technological miracles emerging that will allow them to keep on doing just as they have been doing.  Predictably, the outcome of this high-stake gamble has been a failure not only to decrease carbon emissions, but also to prevent their continued increase. The turn to those alternative technologies that are already available (for example, solar power) has been hindered by the fact that they are often less profitable or require changes in social organization to be implemented effectively.  As a result, greater emphasis is placed on: (1) nuclear energy (a Faustian bargain if there ever was one); and (b) carbon capture and sequestration technology for coal-fired plants, which is neither economically nor ecologically feasible at present, and hence only serves to keep coal, the dirtiest fossil fuel, going. 

Beyond this the only option that the vested interests (the 1% and their hangers-on) have left is to push for geoengineering technologies.  This involves such measures as dumping sulfur dioxide particles in the atmosphere to block the suns rays (with the danger that photosynthesis might be decreased), or fertilizing the ocean with iron to promote algal growth and absorb carbon (with the possibility that dead zones might expand).  These geoengineering schemes are extremely dubious in terms of physics, ecology, and economics: all three.  They involve playing God with the planet.  Remember the Sorcerer's Apprentice! Nevertheless, such technological fantasies, bordering on madness, continue to gain support at the top.  This is because attempts to shift away from our currently wasteful society in the direction of rational conservation, involving changes in our way of life and our form of production, are considered beyond the pale -- even when the very survival of humanity is at stake.

The other approach is to demand changes in society itself; to move away from a system directed at profits, production, and accumulation, i.e., economic growth, and toward a sustainable steady-state economy.  This would mean reducing or eliminating unnecessary and wasteful consumption and reordering society -- from commodity production and consumption as its primary goal, to sustainable human development.  This could only occur in conjunction with a move towards substantive equality.  It would require democratic ecological and social planning.  It therefore coincides with the classical objectives of socialism. Such a shift would make possible the reduction in carbon emissions we need.  After all, most of what the U.S. economy produces in the form of commodities (including the unnecessary, market-related costs that go into the production of nearly all goods) is sheer waste from a social, an ecological -- even a long-term economic -- standpoint.  Just think of all the useless things we produce and that we are encouraged to buy and then throw away almost the moment we have bought them.  Think of the bizarre, plastic packaging that all too often dwarfs the goods themselves. 

Think of military spending, running in reality at $1 trillion a year in the United States.  Think of marketing (i.e. corporate spending aimed at persuading people to buy things they don't want or need), which has reached $1 trillion a year in this country alone.  Think of all the wasted resources associated with our financial system, with Wall Street economics.  It is this kind of waste that generates the huge profits for the top 1 percent of income earners, and that alienates and impoverishes the lives of the bottom 99 percent, while degrading the environment. What we need therefore is to change our economic culture.  We need an ecological and social revolution.  We have all the technologies necessary to do this.  It is not primarily a technological problem, because the goal here would no longer be the impossible one of expanding our exploitation of the Earth beyond all physical and biological limits, ad infinitum.  Rather the goal would be to promote human community and community with the earth.  Here we would need to depend on organizing our local communities but also on creating a global community -- where the rich countries no longer imperialistically exploit the poor countries of the world.  You may say that this is impossible, but the World Occupy Movement would have been declared impossible only a month ago.  If we are going to struggle, let us make our goal one of ecological and social revolution -- in defense of humanity and the planet.
