I really need to write about all the issues I mentioned last week, but this week I’m running behind, so I’ll write a quick book review instead.
My climate book club just read Under a White Sky: The Nature of the Future, by Elizabeth Kolbert. Somewhat atypically for a book about climate change (and other topics, in this case), I have no bone to pick with the author. She did a fine job. Now, it’s true that the book was a difficult read–not that the reading itself was hard, it’s a perfectly accessible and engaging text, but it offers no hope nor any suggestion as to what to do. But Ms. Kolbert is a journalist. Her job is to provide information, not to tell her readers how to feel or what to do. She did her job quite well.
Anyway, the climate authors who have told me to keep my chin up have mostly failed to cheer me as I don’t believe their sources of hope.
I hope, when I hope, for other reasons.
Ms. Kolbert’s premise here is that the distinction between nature and humanity has blurred and will continue to do so. She takes as her topic various people attempting to control natural processes on a large scale in order to fix problems caused by other people attempting to control natural processes–whether such attempts can do anything other than create larger problems yet is a question she asks but does not answer. She does interview several people who argue that at this point we have a moral obligation to try. I’m not sure that’s right. Neither is she.
To be clear, the nature/humanity split has always been fuzzy at best–the idea that humans are not natural or outside nature has always been an illusion. We are no more outside nature than we are outside physics. But it is true that we are changing things that we didn’t used to be able to change. There is nowhere in our biosphere now that is not being influenced or altered by humans to some degree, and that degree is growing all the time. We are at a point where we must acknowledge our collective power and make decisions about it–if Ms. Kolbert has a message beyond the purely informational, that is it.
Years ago, my dad remarked to me that when he first became a home-owner, he found himself in the position of, every day, having to decide whether or not to kill trees. Not that he thought daily about whether to kill them–most days, of course, the possibility of killing trees didn’t enter his mind. But every day he did have the option to call up a tree service and have any of the trees on his property cut down, so that every day he did not do so was an act of mercy on his part, whether the decision was conscious on his part or not.
Once you have the power to do a thing, not deciding ceases to be an option.
(Of course, my dad co-owned the property with my mom, so the image of Dad-as-sole-arbiter-of-tree-life is a bit inaccurate, but that wasn’t his point then, and it’s not my point now)
We, or at least some subsections of we, can now do things like fill the stratosphere with reflective particulates so as to cool the planet by dimming the sun. Whether we should do that, and other things like that, is no longer an avoidable question.
Each chapter of Under a White Sky takes as its topic a different attempt to fix a human mistake at large scales. The first involves invasive Asian carp and the various attempts to prevent their spread and to remove them from where they already are. The story gets pretty weird in places (did you know there are canals that have been electrified as a barrier to fish? There is lots of interesting detail and vivid scenes, much for various species of geek to enjoy. But the scale of the stories covered increases, chapter by chapter, always aiming for the biggie: climate change and the possibility of geoengineering.
Were enough particulates sprayed into the stratosphere to cool the planet, the sky would turn white.
Personally, I think some of Ms. Kolbert’s interviewees may be correct in that the political will to radically reduce emissions doesn’t exist, and that sooner or later geoengineering is likely to become politically unavoidable. Unless the emissions stop, though, that won’t be a solution.
The idea that geoengineering will be part of the solution in any scenario, instead of just another, even bigger, problem, depends on a lot of very optimistic assumptions for which we don’t have good evidence. Of the proponents of geoengineering I would ask why are you picking those optimistic assumptions rather than a different set? As long as we are assuming things….
Ms. Kolbert quotes some people as stating that the emissions just won’t stop, so we’ve got to find other solutions. But that’s not quite right–the only barrier to stopping the emissions tomorrow is political–it is technically feasible. The technical challenge is to stop the emissions without causing disaster, but that’s probably doable. It keeps not getting done because of a lack of political will. It’s important to remember that. There are literally people who would rather the rest of the world burn if it means keeping what they have. It’s important to remember that.
To those who think we can’t reduce emissions without causing widespread human suffering, I say that if we don’t reduce emissions steeply and fast there will be (with or without geoengineering) widespread human suffering. They may be, in some cases, different humans.
I suggest being very careful about making optimistic assumptions that have the effect of deciding which humans get to be collateral damage.
