Food security and secure food in the Anthropocene

Parametric Study of Prompt Methane Release Impacts III: AOGCM Results Which Respect Historical PIOMAS Measurements

“…It is noted that this particular tuning is not considered an advancement in AOGCM science per se, but rather aims to provide a prompt, physics based, historically-accurate and results-focused Arctic phase-change prediction in the near term since the integrity of civilization is rapidly being challenged by the deepening Holocene  Anthropocene climate handover, especially the food supply. [15][16][17] (e.g., There may not be enough time left to wait for significant Arctic/AA model advances. )…”

“… Risk: Northern Hemisphere growing season disruption  Arctic Ocean Cloud Brightening may extend modeled zero-ice dates [6]  Probably required to facilitate any realistic carbon-reduction actions [8,15,16,[24][25][26][27]  A methane burst (clathrates/provinces) moves these dates considerably closer Narrative Summary The importance of forecasting the approaching seasonal zero-ice condition in the Arctic (ca 2035) is the significant potential for periodic disruption of Northern Hemisphere (NH) food production, which is especially grave given that the global NH food production rate already has a decreasing trajectory. [15][16][17] Additionally, based on previous work, it is estimated that if large scale seasonal Arctic ocean warming and permafrost melt facilitates a rapid increase in the atmospheric methane burden [6,[8][9][10][11][12]28,31], the modelestimated dates for Arctic phase changes could be accelerated to 2030 and 2038, respectively, depending on the resulting atmospheric burden of methane as well as the precise rate of increase and timing of release. Even in the absence of a methane burst, the modeled acceleration of global temperature rise by loss of a seasonal sea-ice cover associated with the onset of Arctic phase change (i.e., Figure 1a) is of concern.…”

Biosecurity and more‐than‐human political economy: Veterinary interventions as productive economic forces in the ‘mozzarella landscape’ in Italy

“…It is less a simplified and rigid system that enforces borders, but rather a form of environmental governance that regulates the circulation and movement of human and nonhuman lives and non‐living elements (Barker, 2015). Biosecurity practices have to ensure the free circulation of the ‘good things and people’ while it has to restrict the movements of ‘undesirable things and people’ (Lougheed & Hird, 2017, p. 501). In industrial agriculture, biosecurity is decidedly an anthropocentric project, and its aim is to maintain the intensive mode of livestock farming, where animals are reclassified as biohazards (Braun, 2007), and to satisfy human diets (Blanchette, 2015) through securing food systems.…”

[15][16][17] The global mean surface air temperature rise during the modeled time period is shown in Figure 1a. The modeled rate least-squares linear fit line (0.43C per decade) reasonably reproduces NOAA globally estimated rates.…”

“…The anticipated Arctic phase change is suggested as a rational target for a minimally-damaging geoengineering effort: Arctic cloud brightening, to attempt to slow Arctic ice melt, maintaining the NH food-production basis for global technological civilization. [8,15,16,[24][25][26][27] AOGCM estimates of the impacts of insolation reduction were previously made. [6] However, geoengineering is likely useless without a concurrent global halving of industrial output.…”
