A UK trial 'geo-engineering' project is set to use a tethered, large balloon to see whether airborne release of particles can reverse climate change. The SPICE project (Stratospheric Particle Injection for Climate Engineering), which involves universities and Marshall Aerospace, will use a 20m balloon attached to 800m of 'flexible pipe' to prove the concept. If successful, a high-altitude system could see particles released some 20km up in the atmosphere.
