NASA is reporting that part of the Earth's atmosphere, known as the "Thermosphere",
has apparently collapsed.
"Miles above the surface of the earth, the Earth's atmosphere interacts with space,
a rarefied layer of gas called "the thermosphere" recently collapsed and now is rebounding
issue of the Geophysical Research Letters (GRL). "It's a Space Age record."
"The thermosphere ranges in altitude from 90 km to 600+ km.. It is also where solar radiation
makes first contact with our planet. The thermosphere intercepts extreme ultraviolet (EUV)
photons from the sun before they can reach the ground."
"According to some scientists, this phenomenon could be caused by the fact that quantities of
CO2 gas have it acts as a coolant, shedding heat via infrared radiation.
It is widely-known that CO2 levels have been increasing in Earth's atmosphere"
The thermosphere is the biggest of all the layers of the earth's atmosphere directly above
the mesosphere and directly below the exosphere. Within this layer, ultraviolet radiation
causes ionization. Named from the Greek θερμός (thermos) for heat, the thermosphere
begins about 80 kilometres (50 mi) above the earth. At these high altitudes, the residual
atmospheric gases sort into strata according to molecular mass (see turbosphere).
Thermospheric temperatures increase with altitude due to absorption of highly energetic
solar radiation by the small amount of residual oxygen still present.
