Upper Atmosphere

A new climate modeling study presents a new scenario of how climate and life on our planet would change in response to a potential future strike of a medium-sized (~500 m) asteroid. The effect is represented by a massive injection of several hundred million tons of dust into the upper atmosphere.

A 40 year old loophole exempts satellites that burn up in Earth’s atmosphere from NEPA oversight. As satellites are now meant to be replaced every 5 years, mega-constellations will generate a steady stream of junk in the upper atmosphere where metallic ash could remain for hundreds of years.

A new study reaffirming that global climate change is human-made also found the upper atmosphere is cooling dramatically because of rising CO2 levels. Scientists are worried about the effect this cooling could have on orbiting satellites, the ozone layer, and Earth’s weather.
