Economist: The thawing Arctic threatens an environmental catastrophe

"One possibility for cooling the pole is geoengineering, the deliberate modification of the climate to reduce warming. Pumping sulphate aerosols into the Arctic stratosphere from high-flying aircraft could be one way to blot out a bit of the sun. Such an approach would cool Arctic summers but have little effect in winter because there would be no sunlight to reflect. Injecting salt crystals into clouds over the Arctic ocean, to enhance their reflectivity, might also encourage some cooling, though the helpfulness of this type of intervention is highly speculative."

Sustainable Business: ReWilding the Arctic, Solar Geoengineering Among Last Ditch Options for Climate Change

"Incredibly, a Siberian scientist is actively working to protect permafrost through rewilding.  The goal is to “revive the ice age “Mammoth Steppe” ecosystem across the Arctic, creating the northern Serengeti that was once there."

Berkeley Engineering: One big reflective band-aid

"While Ice911’s work falls in the category of geoengineering, Field is adamant that any climate change technology be removable or reversible, and she stresses that slowing Arctic ice melt is not a long-term solution. Instead, it’s triage until more permanent and sustainable long-term climate solutions can be adopted."

Nunatsiaq: As Arctic warms, interest in geoengineering increases

"Geoengineering could gain countries the time to change from an energy system based on dirty fossil fuels, like oil and coal, which also produce climate-warming emissions, to renewable, clean energy say its supporters."
