These mystifying clouds are called Polar Mesospheric Clouds, or PMCs, when they are viewed from space and referred to as "night-shining" clouds or Noctilucent Clouds, when viewed by observers on Earth. The clouds form in an upper layer of the Earth's atmosphere called the mesosphere during the Northern Hemisphere's summer season which began in mid-May and extends through the end of August and are being seen by AIM's instruments more frequently as the season progresses. They are also seen in the high latitudes during the summer months in the Southern Hemisphere.
...
"It is clear that these clouds are changing, a sign that a part of our atmosphere is changing and we do not understand how, why or what it means," stated AIM principal investigator James Russell III of Hampton University, Hampton, Va. "These observations suggest a connection with global change in the lower atmosphere and could represent an early warning that our Earth environment is being changed." |
I eagerly await the night-shining cloud deniers...

"...things I have neither seen nor experienced nor heard tell of from anybody else; things, what is more, that do not in fact exist and could not ever exist at all. So my readers must not believe a word I say." -Lucian on his book True History
"...They accept such things on faith alone, without any evidence. So if a fraudulent and cunning person who knows how to take advantage of a situation comes among them, he can make himself rich in a short time." -Lucian critical of early Christians c.166 AD From his book, De Morte Peregrini |

Obviously just light reflected from the buildings in the photograph, and probably others beyond the hill. Of course the lights would change and become more frequent and brighter As civilization spreads. Even though I don't know anything about this topic, I think the answer is so obvious that I really don't need to know anything. The real problem is that you see everything through your narrow filter of MMGW and fail to see the big picture, and the obvious answer. 
There. Now that was easy. Next..... |
