News Release: Top-down Planet Hackers Call for Bottom-up Governance
Enviado por ETC Staff el
While most scientists left the Copenhagen Climate Summit feeling gloomy about their influence, a small group of geoengineering advocates came away emboldened by the summit’s weak outcome and uncertain road ahead. This group of scientists aims to get on with research and experimentation in controversial geoengineering technologies. Their real excitement is over “solar radiation management” (SRM). This is a way of “cooling down the planet’s thermostat” by reflecting a portion of the sun’s rays back to outer space, through a variety of techniques ranging from sunshades in space, to aerosol sulphates in the stratosphere, to whitening clouds. These high-risk, planet-altering schemes affect global warming without changing its cause which is excessive greenhouse gases in the atmosphere.
