Governance is the key element in any climate-altering approaches being proposed, particularly from the point of view of climate vulnerable nations, said Professor Saleemul Huq in an interview with C2GTalk. His greatest concern is that decisions that have repercussions for the most vulnerable will be taken without them having a chance to take part in the discussion, so it is extremely important that climate vulnerable nations have a say when decisions are taken regarding climate-altering approaches, including carbon dioxide removal and solar radiation modification.
