Question … since we’re already discussing the idea of geoengineering the planet … why don’t we take shiploads of dry ice from many of our industrial processes and spread it out across the surface of the Arctic’s open waters to cool it down and thereby potentially increase sea ice extent? It’s already going to waste and/or sublimate directly into the atmosphere; seeding the Arctic Ocean’s surface with dry ice (much as you might do with a manure spreader) is no less crazy than the “high speed train to nowhere” Gov. Jerry Brown was pushing in California which is already suffering from billions of dollars in cost overruns. Would the Greenies get on board with that idea more readily than the idea we can convert a global economy to highly variable and highly intermittent wind & solar power?
