Albert- I wonder if liquefied air (Lair) or liquid nitrogen could help in this situation. For example, imagine if large payloads of Lair (-320 F/ -195 C) were sprayed over these regions using aircraft, as it falls it would expand into extremely cold air, which would evenly spread out over the ice

Our research has shown that assessments of Greenland reflectivity change based on MODIS data are problematic. We have looked for darkening trends with MODIS and statistically speaking, we find a hint but nothing definitive. The image shown mentions darkening in 2011 relative to a six-year
