Do So

ENVIRONMENTAL CATASTROPHE HAUNTS THE EARLY TWENTY-FIRST CENTURY, OUR MENTAL MAPS OF SHRINKING RAINFORESTS MATCHED BY images of melting icecaps and dying polar bear cubs. As the thawing tundra releases an amplifying store of methane, the goal of Bill McKibben's 350.org, to reduce carbon in the earth's atmosphere to 350 parts per million, seems wildly optimistic.1 So, too, does much of the discourse of sustainability. How can humans depend on the biosphere's capacity to regenerate, having already destroyed entire ecosystems and caused countless extinctions and continuing to do so at an accelerating rate? Isn't it already too late? What tends to get lost in the linked discourses of climate change and sustainability is the rising seawater—salt water, the stuff that covers seventy percent of the planet's surface. If the ocean, as Christopher Connery claims, “has long functioned as Western capitalism's primary myth element” (686), then literary scholarship engaged with the discourse of sustainability should reexamine narratives of oceanic catastrophe.

The questions that drove Blake’s American reception, from its earliest moments in the nineteenth century through to the explosion of Blakeanism in the mid-twentieth century, did not disappear. Visions of America continued to be part of Blake’s late twentieth- and early twenty-first century American legacy. This chapter begins with the 1982 film Blade Runner, which was directed by the British Ridley Scott but had an American-authored screenplay and was based on a 1968 American novel, Do Androids Dream of Electric Sheep? It moves to Jim Jarmusch’s 1995 film, Dead Man and Paul Chan’s twenty-first century social activism as part of a protest group called The Friends of William Blake, exploring common themes of democracy, freedom, limit, nationhood, and poetic shape.

The Impact

AbstractChanges in land use and climate are the main drivers of change in soil organic matter contents. We investigated the impact of the largest policy-induced land conversion to arable land, the Virgin Lands Campaign (VLC), from 1954 to 1963, of the massive cropland abandonment after 1990 and of climate change on soil organic carbon (SOC) stocks in steppes of Russia and Kazakhstan. We simulated carbon budgets from the pre-VLC period (1900) until 2100 using a dynamic vegetation model to assess the impacts of observed land-use change as well as future climate and land-use change scenarios. The simulations suggest for the entire VLC region (266 million hectares) that the historic cropland expansion resulted in emissions of 1.6⋅ 1015 g (= 1.6 Pg) carbon between 1950 and 1965 compared to 0.6 Pg in a scenario without the expansion. From 1990 to 2100, climate change alone is projected to cause emissions of about 1.8 (± 1.1) Pg carbon. Hypothetical recultivation of the cropland that has been abandoned after the fall of the Soviet Union until 2050 may cause emissions of 3.5 (± 0.9) Pg carbon until 2100, whereas the abandonment of all cropland until 2050 would lead to sequestration of 1.8 (± 1.2) Pg carbon. For the climate scenarios based on SRES (Special Report on Emission Scenarios) emission pathways, SOC declined only moderately for constant land use but substantially with further cropland expansion. The variation of SOC in response to the climate scenarios was smaller than that in response to the land-use scenarios. This suggests that the effects of land-use change on SOC dynamics may become as relevant as those of future climate change in the Eurasian steppes.
