Could sprinkling mineral dust on the world’s oceans actually help slow down climate-change? New research into geo-engineering indicates that it might be possible to remove tons of carbon dioxide from the atmosphere with this technique — but the potential environmental side-effects are giving scientists pause.
The researchers, led by Peter Köhler, of the Alfred Wegener Institute for Polar and Marine Research in Germany, found that distributing olivine — one of the most common minerals on the planet — on the world’s oceans would help make sea water better able to absorb atmospheric carbon dioxide, thereby slowing down global warming.
