The consequences of our carbon pollution provoke an instinctual reaction, but we must consider them rationally. Let’s clearly understand the cause, consider the consequences, and evaluate our options.
Humans have a history of damaging our environment, including driving many species to extinction, from the Wooly Mammoth to the Passenger Pigeon, last observed by Teddy Roosevelt. We have leached deadly chemicals into water supplies, released clouds of cyanide, bleached corals, created toxic fog and smog over cities, poisoned people with mercury, introduced microplastics into most living creatures, burned holes in the ozone, leaked radiation, made rivers burst into flames, filled oceans with garbage, and spilled oil, leaving dead zones. And that’s just pollution, excluding environments and species destroyed by development, drilling, farming, fishing, hunting, logging, mining, ranching, and war.
But our most continuous and consequential pollution is carbon. Especially since Drake’s Well began modern oil drilling, we have extracted fossil fuels of ancient forests that grew 300 million years ago and burned them into our atmosphere, changing our environment into something of which our species has zero survival experience. The last time we had this much carbon in our atmosphere was twice as long ago as when our most primitive ancestors split off from chimpanzees.
- Heat has been increasing, contributing to fires and killing more people every year.
- Droughts have been getting worse, contributing to fires and killing more people every year.
- Glaciers and snowpack have been shrinking, contributing to late season fires and killing vulnerable species.
- Storms have been getting worse, contributing to fires, floods and tornadoes, killing more people every year.
- Sea levels have been rising, threatening to flood low lying cities and coasts.
- Corals have been bleaching—dying en masse—and oceans have been acidifying, killing marine species.
- Diseases have been increasing, killing more people and species every year.
- Soil is becoming less healthy, due to erosion, salinization, loss of micro biodiversity and more.
- Deforestation, melting permafrost and changing water chemistry are reducing carbon sinks and in many cases releasing carbon pollution, like methane, into the atmosphere at increasing rates.
- Species are going extinct at an increasing rate.
- Ecosystems are being damaged, where problems with one or more species affect other species, often in unforeseen ways.
These carbon pollution problems are deadly, unprecedented since humans evolved, are synergistic—meaning that they combine and multiply effects—and will affect everyone negatively, at least economically.
We have alternatives to fossil fuel that cause far less damage and risks to life on earth, especially solar and wind power. In many cases, these alternatives are also cheaper.
Hoping that someone will invent some unknown solution that’s cheap, effective and has no side effects is not rational, given how simple and cheap it is to burn carbon fuel. Carbon capture devices are expensive, especially at the scale needed to shrink total carbon in the atmosphere. Geoengineering is unproven, expensive, and will bring unexpected negative consequences. We do not have any inexpensive, reliable way to mitigate the damage of carbon pollution, apart from reducing carbon pollution.
Rationally, the choice to stop burning so much carbon and convert to renewable energy in order to avoid these ill effects is clear and simple. Dishonesty about the causes, effects, alternatives and consequences is part of the problem. Science, including economics, supports reducing carbon emissions before damage and costs worsen. History shows that violent conflicts arise when living conditions deteriorate and governments struggle to feed and house people.
Instinctually, our fear of death should motivate us to stop burning so much carbon. In future posts, I will discuss other ways of thinking about our climate crisis, but I suspect the problem may not simply be how we think. The basic problem may simply be that we aren’t thinking at all.
