Open access notables Glacier Geoengineering May Have Unintended Consequences for Marine Ecosystems and Fisheries, Hopwood et al., AGU Advances A bold suggestion to reduce sea level rise is to install underwater barriers to reduce the inflow of oceanic heat around Antarctica and Greenland. Inflow of warm, saline water masses drives ice melt and the destabilization of tidewater glaciers. Whilst the basic theory that barriers would stem oceanic heat flow is uncontroversial, the extent to which ...
