The Folly, Egoism and Dangers of Climate Geo-Engineering m...@economicdemocracy.org The Folly, Egoism and Dangers of Climate Geo-Engineering
[I]s humanity so resistant to change that we will tamper with the biosphere's workings to construct a "Frankensphere"; rather than reducing population, consumption and emissions? It is being widely suggested that humanity can "geo-engineer" a global solution to climate change; that is, modify the Earth's biosphere at a planetary scale. Many methods are suggested. Most include either reflecting additional solar radiation away from the Earth, or using the ocean to store more carbon. Reactionary geo-engineering proposals emerge largely from a sense of
desperation as the world fails to rein in greenhouse gas emissions, and
an unwillingness to make necessary societal and personal changes in response
to deadly climate change. To some the extreme action of taking the Earth's
ecological systems into techno-human hands seems sensible given indications
that global heating is proceeding more rapidly than thought, as shown by
unexpectedly quick melting of Arctic
Risky climate geo-engineering schemes include giant vertical pipes in the ocean to increase ocean circulation and thus marine carbon sequestration, similarly growing vast blooms of ocean plankton by fertilizing with iron, erecting giant mirrors above the earth to reflect the sun's energy, and dropping sulfur particles from balloons at high altitude to do the same. Two rogue US companies are moving forward with plans to fertilize the ocean with iron to create plankton blooms to suck heat-trapping carbon dioxide out of the atmosphere. They are motivated by profits from the growing carbon credit market, rising public demands for action, and politicians eager to avoid painful reductions in emissions. There is little that can be done to stop them, as no applicable laws or treaties exist. Such efforts to "manage" Gaia are absolute madness -- betting the planet and humanity on something as complex as artificially regulating a biosphere. Radical geo-engineering proposals could just as easily worsen the situation if these projects fail or are suddenly halted. And it is highly likely that unintended consequences of widespread implementation of such schemes would outweigh possible benefits. Have we learned nothing from the biofuels boondoggle? Failure could destroy the Earth. More: http://earthmeanders.blogspot.com/2007/10/folly-egoism-and-dangers-of...
