Scientists: “Exclusive Club” To Assume Command Of Global Geoengineering
December 21, 2013
Scientific publication envisions “a strategic multilateral implementation (of planetary scale geoengineering) through an exclusive ‘club’ that increases benefits to members at the expense of those excluded.”
In a recent publication published by Environmental Research Letters, three scientists have published the results of a computer simulation “game”, probing several scenario’s on how to best organize a “unilateral implementation scheme” of global geoengineering.
“(…) a sufficiently powerful international coalition might be able to deploy solar geoengineering. Here, we show that regional differences in climate outcomes create strategic incentives to form coalitions that are as small as possible, while still powerful enough to deploy solar geoengineering.”
Defining geoengineering as “intentionally reducing the amount of sunlight that reaches Earth’s surface through the use of stratospheric aerosols”, the authors used climate models (such as the ones used by the IPCC) as the basis for their “gaming” activities- which they describe as “global thermostat setting game”:
“ The characteristics of coalitions to geoengineer climate are modeled using a ‘global thermostat setting game’ based on climate model results. Coalition members have incentives to exclude non-members that would prevent implementation of solar geoengineering at a level that is optimal for the existing coalition.”, authors Katharine Ricke and Ken Caldeira point out.
