Climate Change and National Security: Implications for Space Systems

With an albedo of 80 percent or more, snow-covered terrain reflects most incoming solar radiation back into space. If the cover melts, the albedo drops to less than 30 percent, allowing the ground to absorb more solar radiation, heating the surface and lower atmosphere.Originally Published by Aerospace- The effects of climate change constitute an unprecedented threat to global security and military readiness. What, if anything, can the space community do to prepare?
