Geoengineering field testing


A team of British academics will in October 2011 start conducting field-tests, pumping water into the air from a balloon at a height of 1km. Ultimately, they aim to test pumping sulphates into the stratosphere from a balloon at 20 km height.

The balloon could also be used to test "cloud whitening", i.e. pumping up fine sea salt crystals and spraying them into the air to increase the number of droplets and the reflectivity in clouds.

Press Release: The SPICE project: a geoengineering feasibility study (September 14, 2011)

Editor's note: The test, part of the UK-based Stratospheric Particle Injection for Climate Engineering (SPICE) project that receives £1.6m support from UK research councils, has meanwhile been put on hold, following the councils' advisory panel's recommendation to delay the project.
