March 16 2019 Book review: The Uninhabitable Earth: Life After Warming by David Wallace-Wells, (c) 2019. Finally finished this very engaging not-too-long book (300 pages, including notes and index). As previously mentioned, the book is an expansion on the author's 2017 New York Magazine article [1] by the same title. Alex Smith of Radio EcoShock interviewed Wallace-Wells recently [2]; worth listening to whether or not you read the book. Being someone who is naturally attracted to the more depressing end of the spectrum of writings concerning climate change, resource depletion, environmental destruction and the likelihood of civilizational collapse, this was a book I was destined to read. The very first sentence sets the tone: "It is worse, much worse, than you think.". And indeed, it really is. Likely the vast majority of people, at least in the US, base their understanding of climate change off of skimmed headlines referencing the ebb and flow of mere degrees and/or rates of warming, perhaps making a mental note not to buy Florida beachfront property. The actual ramifications of those few extra degrees of warming is much more extensive, much more severe, due to the cascading of interlinked systems that constitute our imperiled still-blue planet. The first section, Cascades, lays out the evidence to date for global warming (GW) and the central role it played in 4 of the 5 past mass extinction events. Basically massive volcanic activity got things going, triggering arctic methane releases (hydrates and/or thawed permafrost) which delivered the doom. The fact that our current anthropogenic GW is occurring at least 10x the rate of those past extinction events should be enough to give us big brained primates pause if we were truly rational beings. Sadly, we are anything but. The next section, Elements of Chaos, methodically goes through all the ways things can go sideways as GW progresses unchecked. Twelve short chapters with titles like Heat Death, Hunger, Dying Oceans, and Economic Collapse explore the multiplicative pile up of stressors. The author's goal seems to be to spell out the range of possibilities, an eye wide open view of possible futures. I took a lot of notes through this section which contains many factoids like "at 7 degrees C warming humans and other mammals lose the ability to cool their bodies via panting and/or sweating", a real possibility for countries straddling the equatorial band such as southeast Asia, a truly uninhabitable scenario. A few of the more notable notes: - Saudi Arabia burns roughly 700,000 barrels of oil per day to air condition buildings in the Summer months when temperatures can reach 120F. - general rule of thumb for crop yields: 10% loss per degree C warming for cereal crops; cereals plus soy and corn provide roughly 67% of human diet. - after India, US is the most vulnerable to GW due to coastal development. - by 2030 global fresh water demand will outstrip supply by 40%. - each degree C warming means 20-40% increased likelihood of war/conflict. Section III, Climate Kaleidoscope, focuses on cultural, political, ethical aspects of what has come to be called the Anthropocene. It is also the weakest section, though to be fair this kind of stuff is hard to get a bead on; we are the fish in the fish bowl after all. The bits that resonated most for me had to do with our economics and technology. I noted the following: Crisis Capitalism chapter: - most can easier imagine the end of civilization than the end of capitalism, or even the possibility or _not_ incentivizing burning fossil fuels. - climate change will likely end capitalism as we know it as the cost of adaptation and mitigation escalate, flat-lining any economic growth. The Church of Technology chapter: - the transition of electricity generation from "dirty" to "green" sources is the lowest of the low-hanging fruit; electrifying everything will be orders of magnitude harder and in many cases not possible at all. - despite the technological advances over the last several decades, our standards of living has been largely static; advances tend to simply add to energy and resource use. My biggest contention with the author is with some of his positions taken under Politics of Consumption where he suggests that the adoption of seemingly more ethical behaviors such as eating less meat and biking/walking instead of driving are little more than lifestyle choices stemming from neoliberal values that equate "right living" with substantive political engagement and are therefor a cop-out. To some extent I agree with that, however one doesn't have to engage in the US political system much before concluding that political engagement shares much in common with banging ones head against a wall. Most people have neither the time nor the fiscal luxury of direct political involvement in the current system. That leaves engagement through donations to various proxy groups, many of which to my eye look completely ineffective. Which leads back to where I suspect many people are, disengagement from the larger system to whatever extent possible, and personal ethical choices. By the way, Wallace-Wells thinks disengagement is also a cop-out. He is a parent which I suspect taints his point of view; all parents want a better world for their children, whatever it takes. The book wraps things up with History After Progress, which makes the case for recessing our relatively recent experience with Growth, Progress, and perhaps civilization in general as little more than a temporary reprieve from humanity's norm which as been largely as hunter-gathers (95% of modern humans lived this way), later as agriculturalists (last 12,000 years) for which gains in food security were offset but poorer health, long stretches decidedly lacking in anything that looked like economic growth and progress. Several civilizations did arise but depleted their resources and collapsed, a reversion to a subsistence mean. That our current civilization has, at least for some, seemed so full of wonder and possibilities, we can largely thank fossil fuels. But we have been so enamored with the view out the windscreen that we didn't contemplate the cloud of exhaust trailing behind. Now the winds have shifted, the tank is edging south of '1/2', and that open road turned out to be a round-about in need of repair. Closing thoughts: In general I found this to be a well-considered, engaging book. Wallace-Wells is a gifted writer and his style is a nice balance of word-play, enough factoids to make a point but not overwhelm, responsible use of references (no excessive name-dropping, no out-in-left-field sources). Several reviewers have accused the book of alarmism, however the author is simply presenting the range of possibilities and predictions based on science that always contains a degree of uncertainty. I spent some time in the Notes section and didn't find any references that seemed unsubstantiated -- most are books, papers and articles published by respected institutions. The fact of the matter is this information IS unsettling, and alarm is a normal response. That so many instinctively move to dismiss the message of Wallace-Well's book reminds me of that old John Steinbeck quote: "It is difficult to get a man to understand something, when his salary depends upon his not understanding it". So many of us have so much to lose by killing fossil capitalism even as it not-so-slowly kills us. And so we have school kids cutting class to protest the theft of their futures while their parents feed the beast -- it's koyaanisqatsi. - - [1] gopher://gopherpedia.com/0/The%20Uninhabitable%20Earth https://en.wikipedia.org/wiki/The_Uninhabitable_Earth [2] https://www.ecoshock.org/2019/02/uninhabitable-earth-david-wallace-wells.html
