“…[T]o slow global warming, science has been exploring ways to manipulate the climate…[G]eoengineering offers promise...[but]comes with all kinds of potential pitfalls…[It] can be as simple as planting trees to remove CO2 from the air or as complicated as trying to use giant mirrors to reflect the sun into space or using wind-powered pumps to refreeze parts of the Arctic…[One proposal being studied is scattering fine particle in the upper stratosphere to] reflect some of the sun's rays and reduce or maintain global temperatures…[But once] you begin a solar geoengineering process, can you stop it? What happens if things don't go as planned? And what about the repercussions of CO2 emissions not related to global temperatures, such as ocean acidification?...[Scientists say it could have 'huge' unintended consequences on those least responsible for climate changes]..." click here for more
