In which the ill advisory of five geoengineering concepts for the polar regions are discussed. Climate change impacts are especially pronounced in the polar regions. Instead of reducing carbon emissions, concepts have been devised to geoengineer instead: 1) stratospheric aerosol injection (SAI) 2) sea curtains 3) sea ice management 4) slowing ice sheet flow 5) ocean fertilization. Obviously, all only mask impacts rather than address root causes. For 1), would require 60k flights annually for lasting effect. Ending in future would cause rapid immediate warming. Would have no impact on polar regions in winter (no sunlight). Cause ozone depletion. Disrupt global climate patterns. Who governs? Cost at least $1 billion/year.
