    The Solar Radiation Management Governance Initiative says geoengineering could be 'plan B' for climate change More research on the risks and governance of geoengineering the planet's climate by reflecting sunlight into space is needed, a grouping of science bodies and a green NGO have said, as the end of the first week of UN climate talks nears.

    Opponents of geoengineering will no doubt seize upon this week's cancellation of the fieldwork element of the Spice project as a significant victory in their campaign to outlaw research in this area. There are important lessons to draw from the problems encountered by the project, which planned to investigate the feasibility of spraying particles into the stratosphere to mitigate global warming.

    A controversial geoengineering experiment to simulate the cooling effect of volcanoes has been cancelled due to concern over a perceived conflict of interest with some of the researchers. The experiment would have injected 150 litres of water into the atmosphere from a weather balloon via a 1km pipe tethered to a ship as part of the Spice project (Stratospheric Particle Injection for Climate Engineering).

    Blue skies would fade to hazy white if geoengineers inject light-scattering aerosols into the upper atmosphere to offset global warming. Critics have already warned that this might happen, but now the effect has been quantified. Releasing sulphate aerosols high in the atmosphere should in theory reduce global temperatures by reflecting a small percentage of the incoming sunlight away from the Earth.

    Spritzing a sunscreen ingredient into the stratosphere could help counteract the effects of global warming, according to scientists behind an ambitious new geoengineering project. The plan involves using high-altitude balloons to disperse millions of tons of titanium dioxide-a nontoxic chemical found in sunscreen as well as in paints, inks, and even food.
