ONCE IN A WHILE, and with increasing frequency, climate change rises to the forefront of popular consciousness. It happened, for instance, in 2007, when An Inconvenient Truth won two Oscars and extreme heatwaves swept across the US and Europe, causing wildfires that torched over ten million acres of forest. A critical mass of people aided by the notion that others are doing something similar can break through the powerful psychological resistance and look the blinding thing in the face. It’s devastating and painful; you grieve and you panic. Even so, there’s relief in bringing something so painful into view, in holding it with your mind. But you can only look for so long. Resistance reasserts itself, and you slide back behind it. Next time you come out a tiny bit further before you retreat. This is how understanding happens, through a series of breakthroughs and retrenchments and consolidations, as with all efforts toward intentional growth. A single revelation is rarely enough. Even though “we know, we know,” as Bellow’s Mr. Sammler says about the human moral impulse, we also forget, forget.

So much of our daily behavior is confused and uncertain. We can’t seem to lead the lives we have and acknowledge the future simultaneously, even as we must. We keep our eyes on the middle distance — our hopes for the country (universal healthcare!) and for ourselves — and only feel the shadows on the horizon across our peripheral vision. We are everyday climate deniers the way we are everyday death deniers: we write our articles, save for “retirement,” canvass for causes that give us the most hope. We go to bars and ask our friends whether they plan to have kids. Those of us with kids have become “preppers” in both senses, drilling our toddlers with blocks, trilingual board books, and Raspberry Pis to ace the local magnet preschool’s entrance exam while lobbying high schools to teach organic farming and archery. Perhaps we should start cultivating other friends, those with hand skills, for when civilization breaks. But what will we be able to offer in return? We can edit their mission statements! More likely we’ll do the unskilled labor, like rusticated Chinese intellectuals during the Cultural Revolution. Perhaps our arrow-slinging children will bear us on their backs out of the civilization we ruined for them.
