If the plan works, the team will move onto bigger balloons, higher altitude and -- eventually -- sulphate aerosol particles.
www.wired.co.uk The technique could be replicated around the world by jettisoning sulphate aerosol particles from a 20km-high, stadium-sized balloon.
www.wired.co.uk The sulphates would wash out within a couple of years but again this "solution" does not address ocean acidity, or the potential acidity of the sulphate aerosols.
