There'll come a time when airplanes are much more efficient when it comes to producing lower levels of greenhouse gas emissions, there'll come a time when we'll be able to offset those emissions much more effectively than we do now. But alas at the moment, flying airplanes is really one of the least defensible things that we do and it's one of the things that I indulge in quite frequently, alas.
If I drive my car to the store, those carbon molecules that are emitted actually get into the atmosphere circulation systems and affect climate in a global basis. This is shocking, this is amazing! No one in the 18th Century would have believed that anything like this were at all possible and I don't think we have, as part of our common sense, morality, norms and values that are really responsive to those kinds of issues, to the kind of power that we now are able to exert over the future and over people who live very far from us.
Apocalypses don't happen very often. They tend to be separated by tens or even hundreds of millions of years.
I grew up as an only child of two parents who had dropped out of high school. They had enormous respect for education and encouraged me as a child when I had strong interests in both math and science, but we really didn't have much by way of educational role modeling in our family.
We think of history as another specialization, like philosophy of language, rather than as something that informs everything we do and think.
Even those who specialize in the history of philosophy often ignore the political and cultural context, and the natural world in which their philosophers were philosophizing. This has consequences both trivial and important. If you systematically read the last fifty years of the major journals in our discipline you would be amazed at the amount of redundancy. Most of this is unacknowledged because most of us know so little about the history of our discipline and even the subfields in which we work.
We know the "great men" and a handful of heavily cited papers in our specialization. When there is a historical frame around a paper it's often a caricature that has become canonical.
If we don't have historical consciousness we can't really understand problems in all their dimensions, and if we can't understand problems than we can't find solutions.
It's true that climate change is an unprecedented problem so it's not surprising that it's so difficult to address.
Our traditional systems of decision-making are just not up to preventing changes in fundamental earth systems that are driven by a constant barrage of individually negligible emissions of an invisible, odorless gas, by billions of people all over the world.
We need to use economic instruments such as carbon taxes, cap and trade, tax and dividend and whatever else to help incentivize behavior that will move us to a post-carbon, post-animal agriculture world, and make our societies more resilient to the shocks that are already baked into the system. But that doesn't make climate change an "economic issue."
We can use economic instruments to help realize our goals but economics does not tell us what our goals should be.
Ethics is prescriptive and can change behavior, but usually only at the margins.
Ethical systems are fundamentally conservative and primarily directed towards regulating interactions within communities.
Climate change involves behaviors that are individually negligible, whose impacts go far beyond the spatial and temporal constraints that define our sense of community.
People who go around saying that it is wrong to fly and to eat meat are not so much making appeals to us from within our shared morality, but engaging in something more like "persuasive definition." They want us to look at the world and ourselves in a different way. Someday these prohibitions against flying and eating meat may be written into our moral psychology, but it will only be after there are viable, widely shared alternatives that are beginning to be widely adopted.
People with long memories and a vivid sense of the past have an immediate understanding of politicians like Donald Trump. They are not surprised by the behavior of Google, a corporation that notionally (until recently anyway) espoused the slogan "don't be evil" and then runs over individual people and even entire nations in the pursuit of profit.
We live in a world in which everyone wants solutions. But we can't find solutions if we don't understand the problems, and we can't understand the problems without knowing how we got here.
The Enlightenment is not a nightmare, nor is it something that comes easily to us. It is an aspiration - and a good one!
I became religious and at 14 went to a boarding school 500 miles from home to begin theological studies. By the time I started university, politics had replaced religion in the economy of my enthusiasms but I had no idea what to study. My boarding school emphasized languages which I was bad at, and deemphasized math and science which I was good at.
I played with English and Sociology in college but dropped out to work in the anti-war movement. I was going around denouncing the Viet Nam war as immoral but one day it dawned on me that I didn't know what that meant. I signed up for an ethics class at San Francisco State to find out the answer.
A great deal of our math, science, philosophy, and everyday behavior presupposes that stability and equilibria are the "default" states, and everything else involves some "perturbation." This is a mental model, a conceptual frame, a tacit belief, a presupposition - whatever you want to call it.
Most of what we think of as distinctively human has occurred in the last 10,000 years in the Holocene - a period in which the Earth was abnormally quiet.
If we're interested in the continuation of the human experiment we need to focus on resilience and coping with change (whether natural or anthropogenic) rather than living as if God or nature has given us a nice, orderly, calm, Babbit-like existence.
Most "process" philosophy is historicist (e.g., Hegel) and not concerned with "deep time." Maybe Whitehead is an exception. He may be a really important philosopher for all I know. I've never been able to read him.
