Paganism at One with Science
If there were no carbon dioxide in our atmosphere, the entire surface of the earth would be buried in solid ice. Fortunately for us, throughout all of human history, trace levels of CO₂ have stayed between 260 and 280 parts per million, trapping just enough heat from the sun to make civilization and human life itself possible. Over the last two centuries, however, industrialization and the burning of fossil fuels have added over forty percent more CO₂ to the atmosphere, to 400 ppm, and that number has been climbing rapidly. So, if CO₂ should be trapping much more heat in the atmosphere, why does it not feel significantly hotter?
The answer is in the oceans, which have thus far been mitigating the effects of global warming. In addition to acting as a carbon sink, absorbing some CO₂ from the atmosphere as carbonic acid, the oceans have been acting as a heat sink as well. They are currently (and unevenly) absorbing the excess heat being trapped in our atmosphere by the additional CO₂. As anyone who has ever patiently watched a kettle boil knows, water holds a lot of heat. That has acted to delay the consequences of exploiting fossil fuels, so far. Over the next several decades, however, the heat-carrying (and carbon-carrying) capacity of the oceans will reach an equilibrium with the atmosphere, and then the extra heat being trapped will have no place left to go. The earth’s surface will become considerably hotter. Worse still, that excess heat will increase water-vapor in the air and will hasten the melting of the Greenland and Antarctic ice sheets and northern permafrost, decreasing the earth’s reflectivity and releasing from beneath the surface trapped stores of methane, a much more potent greenhouse gas — all greatly compounding climate change. We have already destabilized the climate; it is done. Yet climate does not respond instantly. There is a time lag. In fact, if we were somehow to cease all CO₂ emissions immediately, the earth would continue slowly to heat well beyond this century, until a new and hotter global equilibrium were eventually reached. And yet we are still recklessly adding over one hundred million tons of additional CO₂ to the atmosphere every single day!
Some have claimed that converting swiftly to renewable sources of energy will damage the economy. This is factually false. During World War II, the United States government spent massive amounts of wealth on a monumental increase in military capacity to fight fascism. The postwar result was the greatest economic expansion in the history of the country. We could easily accomplish this again, improving capacity for sustainable energy rather than military capacity. And climate change represents a much graver threat to global civilization, to the very survival of our species, than did even the grotesque evils of Nazi Germany, Fascist Italy, and Imperial Japan. Climate change will effectively be permanent and portends severe droughts, famines, resource wars (with or without nuclear weapons and potentially far deadlier than World War II), coastal inundations, whole populations of refugees, and civil unrest on a scale unprecedented in history. If the moderate projections of most climate scientists are accurate, it is uncertain whether civilization, or even humanity, will be able to survive in the long term.
The fossil-fuel industry has used its political and economic influence to resist the conversion to clean energy because, while it owns the fossil fuels beneath the ground, it does not own the sun and the wind. No one owns such renewable resources, and so they cannot be centrally controlled for private exploitation and profit. Industry planners, like those of the tobacco industry before them — in some cases, the same individuals — have worked to sow doubt about the science among the public, in order to continue to sell their harmful products. To delay reform, they have needed only to spread confusion about what are in fact settled questions among the large majority of climate scientists. The major fossil-fuel companies have assets at stake in excess of a trillion dollars. To understand their motivations, we need only follow the money.
By delaying, by not deciding whether to alter our course, we have in effect made a fateful decision not to act. Because of those delays, dramatic climate change is inevitably coming. We can work only to mitigate the disaster ahead. The earth has entered its sixth extinction event, and the complete disappearance of humans (and all other megafauna) is by no means beyond the realm of possibility. This is not about saving the planet. The planet has been through far worse in its four and a half billion years. This is about saving civilization and any decent survival for our descendants, perhaps even about saving humanity itself.
For all people, the religiously faithful and the genuinely skeptical alike, but mostly for people of relative privilege, climate change is a moral issue. It is in fact the defining moral issue of our time. Please consider sharing this message.
