The clouds were spotted by NASA's AIM spacecraft, which observed a "vast bank" of the clouds that began on November 20 and has expanded to blanket the entire continent, creating a rippling mass of particles that represent the highest clouds formed on earth. The clouds "glow" because of their altitude - they reflect light cast from a horizon we can't see from the ground. But what causes these clouds to form so high above the surface of the earth?
Last year, atmospheric scientists from Hampton University published a study revealing the discovery of "meteor smoke" in the clouds. When meteors get pulverized in the atmosphere, they leave behind a trail of tiny bits floating in the upper reaches of the atmosphere. It turns out that these microscopic "meteor clouds" provide the building blocks for noctilucent clouds - water molecules gather on the specs of dust, creating ice crystals.
Comment: NASA is blowing more 'meteor-smoke' in our eyes!
After acknowledging that NLCs are increasing due to the increased extraterrestrial factor, NASA then tries to blame rising methane levels from below, suggesting that human industrial activity is responsible for both.
This is a rather pathetic attempt to blame NLCs on 'man-made global warming'!
Rising methane levels are due to methane being released from deep under the oceans.
Increased NLCs are a 'canary in a coal mine' alright, but not in the way Official Science would have us believe.
Since Official Science won't spell it out for people, it's left to citizen observers to do so:
