New Papers from the Anthropocene Working Group (part 5)

Jan Zalasiewicz et al., “Making the case for a formal Anthropocene Epoch: an analysis of ongoing critiques,” Newsletters on Stratigraphy 50:2 (2017)

What’s been needed to move forward the debate about formalizing the Anthropocene epoch as a new entry in the official Geologic Time Scale? A paper exactly like this one. Over the last five years a string of papers have been published critiquing the Anthropocene as a geological concept. They’ve contained substantive arguments and weaker arguments; they’ve added to and overlapped with one another. In this paper, the AWG members (with one notable additional contributor) systematise and respond to those critiques. It’s invaluable, clarifying work.

The Rhythms of History

The blog is still in hibernation for now. But here’s a short piece I wrote for the UC Press blog about the 2017 American Historical Association conference.

The American Historical Association’s annual conference begins in Denver on January 5. The panel I’d most like to go to is no. 142, “The Anthropocene in History,” chaired by John McNeill. (I wrote about Prof. McNeill’s most recent book here.) Being used to more modestly sized British conferences, I’ve never seen an academic conference panel take place in a ballroom, as the programme claims this one will.

Hibernation

In Britain, the common hedgehog goes into hibernation at just about this time of year. Its body temperature will drop (Hugh Warwick writes) by some 25°C; its heart will slow to five beats a minute; it can go for an hour between breaths. In the case of erinaceus, however, hibernation is triggered not by the cold but by the demands of the academic calendar. In other words, I’m putting the blog on hold until the spring because I’m busy with teaching. Expect a new series of weekly posts to begin next May. Continue reading “Hibernation”

Five Maxims

Throughout this blog so far I’ve stayed pretty close to the arguments I made in The Birth of the Anthropocene. But in each post up till now I’ve also tried to add something new, rather than just reprising what I’ve already said in print. Since this will be the penultimate post on Made Ground this year, though, it seems a good opportunity to give a more explicit summary of the book itself. If you haven’t read The Birth of the Anthropocene but you’d like to know what its argument is, for the purpose of citation, disagreement, or mere curiosity, this post is for you…  Continue reading “Five Maxims”

Eemian Bonds

James Hansen et al., “Young People’s Burden: Requirement of Negative CO2 Emissions,” under review for Earth System Dynamics

Why does the geological version of the Anthropocene matter to ecological politics? Because the ecological crisis has politicized geological time. The clearest pieces of evidence that the crisis has made deep time a political issue are newspaper headlines like the one in last Tuesday’s Guardian: “Planet at its hottest in 115,000 years thanks to climate change, experts say.” Headlines like that one—or like the New York Times’ front-page announcement in 2013 that CO2 levels are at their highest for at least three million years—are the starting point for the account of the Anthropocene that I gave in the book. A new and discombobulating temporal scale has made its presence felt in current affairs. The idea of the Anthropocene epoch is one way of coming to terms (as far as it’s even possible to come to terms) with that disturbance of scale. Continue reading “Eemian Bonds”
