Interview in article on methane removal technologies.
'Methane, long eclipsed by carbon dioxide  (CO2)  as  a  villain  in  climate change,  is  having  its  moment  in the  spotlight.  The  United  Nations climate  summit  opened  here  this week  with  faltering  global  com-mitments  to  reducing  CO2,  but  more  than 100 nations have agreed to cut their meth-ane  emissions  by  one-third  by  2030.  Officials  hope  cracking  down  on  the  potent greenhouse gas will help limit global warm-ing to a 1.5°C rise, the goal established by the 2015 Paris agreement.'
'Emitting just 10% of the amount of iron that naturally reaches the atmosphere in mineral dust could be enough to restore methane   to   its   preindustrial   level,   says Matthew Johnson, a chemist at the Univer-sity of Copenhagen.'
