I'm very concerned about two GM technologies, which don't seem to have attracted the concentrated attention of geoengineers and earth scientists.
Firstly, the creation of root nodules to host N2-fixing bacteria on non-leguminous plants. This can fundamentally alter the nitrogen cycle, and indirectly the carbon cycle. Secondly, the switching of C3/C4 photosynthetic apparatus. This can fundamentally alter the carbon cycle. Both of these have the capability to create new plant types with fundamentally higher primary productivity. Because these may outcompete wild species, they may be uncontrollable once released. I'm generally unconcerned about GM, but these technologies are potentially severely dangerous. In my opinion, they clearly fall into the realm of (potential) geoengineering, and I'd be pleased if people on this list could devote a little time to discussing these risks. If you're looking for a more direct link, the biofuels / biochar / BECCS angle provides an obvious entry point to the debate.
