there s very little that s green about orrock quarry in fife. the black basalt hillside is being steadily eaten away to make concrete and asphalt for new roads. this is our magic dust. basalt is a volcanic rock found in abundance around the world. and as it weathers in the rain, it takes the greenhouse gas carbon dioxide out of the atmosphere. that s what s balanced our climate for the last millennia. enhanced rock weathering is a way of turbocharging that natural removal. what we do is we use this fine material which massively speeds up the process. what we do is we use this fine material which massively speeds up the process. so more contact between the rain and the rock? we watch as the basalt is spread. the science is still new but it is thought that scattering about 1.5 tractor loads cancels out a typical brit s annual carbon footprint. for the world to stop warming, we re going to have to stop putting more carbon dioxide into the atmosphere. this isn t going to fix that. but the
