Geo-Engineering: A Solution to Climate Change Not Worth the Risk
"Save Planet Earth" - Is it even wise to think on such a grand
scale?   Some suggest geo-engineering as a “fix” to climate
change. Technology wrought large.  Techniques such as using
mirrors or seeding the atmosphere with sulfur particles to block
solar radiation from reaching Earth’s surface could cool the
planet, but with its own unintended and undesirable
consequences.  In an essay in last Friday’s Science Daily,
scientists warn that the risks of global-scale geo-engineering
far outweigh the possible benefits.  Ecologists speaking at the
annual meeting of the Ecological Society of America held a
symposium to discus some of the methods proposed for large-scale
manipulation of earth’s natural systems to absorb atmospheric
CO2,, affect cooling, and thus  reduce warming. Despite this
interest in geo-engineering as a solution to global warming,
most scientists at the meeting consider not worth the risk any
attempt to engineer climate at a global
