Excerpts;

A pilot project at a lake in northern Alaska is one of a number aiming to slow climate change with geoengineering – Tiny spheres of reflective sand will be sprinkled upon the lake to see if this can prevent the lake ice from melting or slow the process down.

Scientists are attempting to resurrect the reflectivity lost by the Arctic as sea ice has receded due to a warming atmosphere and ocean. Sea ice is being lost at a rate not seen in at least 1,500 years, with Nasa calculating it is disappearing by about 13% a decade…
